Docking Systems

MODULAR FLOATING DOCK SYSTEM for aquatic sports, aqua culture and environmental protection

Maritime Technic - Pontoon System25 years experience in "state of the art" floatation engineering worldwide, together with cutting edge technology and the most advanced production techniques are the base for the new extremely versatile PONTOON BUILDING BLOCK SYSTEM.

By utilising the friction co-efficient achieved by independent controlled flooding of modules we have refined this system to provide not only the most stable floating platform available, but also a high load capacity which can also be combined with a fender-sidebar system.

The single modules are easy to handle (weight: 6,2 kg) and guarantee a very high load capacity of 360 kg/m2 (815 lbs/10,8 sq ft). They are made of a high-quality synthetic, UV-stabilized and anti-static green material (Novolen) which is extremely resistant to the elements! With block measurements of 50 x 50 x 50 cm (1,65 x 1,65 x 1,65 ft), the standard freeboard is approximately 40 cm. Blocks are easily assembled by connecting 4 elements (= 1 m2) via connecting lugs, with one bolt which gives a secure, stable connection.

This building block system can be varied according to any desired layout or measurements and can be used to replace or extend existing pontoon systems. This seawater and acid resistant system requires no maintenance or cleaning and is extremely durable. It can be utilised throughout the year or the single modules can be stacked and stored. Unlike conventional wooden floats, the pontoon is made of a skid-proof material, and will not rot, it is also safer as it won't splinter, or have sharp edges, rusty nails etc.

The "Maritime-Technic- Pontoon System" contributes to water purity, is aesthetically pleasing and comes equipped for various anchoring configurations. Swimming ladder, railing post and boat fastening-eye are main accessories with options such as fender systems, UV- resistant ropes and for marinas, electricity distributors (w/wo illumination) are available.

ELECTRO MOTORS for boats and pontoons

Electro motors (shaft, screw and flange models)For boats, an electro motor is practicable for up to 9 m total hull lengths. Electric motors have, compared with petrol motors, different turning moments, which allow to use electric motors with relative low powers. Longtime experiments have proven, that the required power relation (electro to petrol motor) can be 1:2.0 to 2.5, if the pertol motor was not over motorisized for the boat and the use.
All models have a compensated row motor, which coiling compensation optimizes the energy usage and increase theoutput of the motor, specially at higher turns. The casings as well as all supports are made from marine aluminium (GalSi5Mg to DIN 1725, pp. 2), which is corrosions and seawater proof. All other materials incl. all screws are made from stainless steel. The ball bearings are made for long operation and live and the seals of the bearing are made form seal rings. All parts are covered by plastic or special paintings for additional protection. Motor and motor casings are also painted with antifouling. All parts are built with high precision and each motor will be tested to electric performance.

The outboard-shaft models have a weight of 19-21 kg and are delivered with integrated cable, switch and fuse. They are ready to use and just have to be mounted on the heck and connected with the cables to the battery. Available in 3 power sizes (500, 800 or 1.400 Watt) with 4 steps (2 front and 2 back) and with different staft lengths for various boat types.
The inboard-flange models have a weight of 15-35 kg and are delivered with complete cables, switch and fuse. They must be installed on the boat and are fitted with a pinn, where lenking ropes can be fixed. Available in 4 power sizes (800, 1.400, 2.000 or 3.000 Watt) with 4-6 steps (font and back).

A foldable propeller, which brings the wings into a position so that they doe not turn if the motor is not used, is available as accessoire.
Additionally, special batteries for long time use with high cycle stability, battery loaders, and (from 36 V on) a stepless motor regulation is available.

Netcage Systems

SUBMERSIBLE WAVE PROOF OFFSHORE NET CAGES for fish farming

 Layout

This cages are developed for industrial farming of various fish species (i.e.: Sea bass, Sea bream, Grouper, Salmon, Trout, Sturgeon) all the year round at exposed open water areas such as seas and oceans. To prevent damage from storm impact and to provide optimum conditions for fish farming, the cage can be submerged.
Completed with a painted or galvanized framework with a net chamber enclosed and a feed bunker on it allowing automatic feed supply and farming process supervision. To place the cage vertically, it is equipped with a special system providing its surfacing, submerging and positioning at a depth of 4-40 meter. Horizontal positioning of the cage is provided by the system of anchorage including anchor ties and anchors. Lightness and tracery of the cage are in full accordance with the sea landscape.
The cage structure is produced to the "Rules for Building and Classing Underwater Vehicles, Systems, and Hyperbaric Facilities" and passes control assembling and testing at the manufacturing plant. It will have the certificate of the official "Maritime Register of Shipping".
The steel work is marked and packed as packages or in boxes which can be transported in a standard 40-feet container.
The basic material of the (polygon) framework consists of rod welded tubular low carbon (grade A) steel elements, connected with each other by flange bolts. The three-dimensional framework forming a regular nonahedron in plan, with three slanting trusses, running from the vertical columns to the geometric centre, closing at the feeder casing. The upper contour is completed with service platforms, passage walkways (500 mm wide) with railings (1.000 mm high) and removable hand ropes, also to the feed bunker. The walkways and brackets are made of pipes with 120 mm in diameter. The vertical columns (720 mm in diameter, 2.250 mm long) house permanently buoyancy compartments, balancing tanks, and compensation tanks of residual buoyancy resulting from discharge of changing loads. Also sensors that measure depth of submergence, water temperature and underwater acoustic are housed there. The 5.980 mm long horizontal members of the bottom contour are made of pipes with 478 mm in diameter and house the main ballast tanks and compressed air cylinders, 6 of which are ballast compartments and 3 are compressed air cylinders. Three mooring walls with wooden guard rails are provided for service boat mooring. To provide for safety of work of the attending personnel, the cage is equipped with removable single row life-lines. The shape of the whole structure and all separate sections are adjusted so that the cage experiences minimum rolls and trims at waves and current. The experience of the underwater system operation has proved that the operation in the water column is the most effective structural measure to protects structures from corrosion. Hot galvanized coating provides the structure service life of more than 20 years. This coating is reliable, practically excluding restoration and repair.
The system of automatic underwater feed distribution is intended for storage and measured distribution of feed for an autonomous operation of 7-30 days and located at the geometric centre of the cage. The system consists of a water tight bunker of 3.000 litre (2 tons feed in average) of cylinder conical shape (1.412 mm in diameter and 2.890 mm in height) and an automatically feed distributor (with a microprocessor) with a volumetric type dosage of 5 litre each. Compressed air is supplied to the pneumatic device by pipelines from compressed air cylinders, which are replenished from a service boat, equipped with a compressor. To prevent water penetration into the feeder, its upper part is equipped with a water tight hatch with a rack-and-pinion lock. Inside the feeder the upper part houses solenoid valves, system controller and (24 Volt, 125 Ah) batteries. The system is made of corrosion proof steel (6-8 mm thickness) and non-ferrous metals.
To submerge and surface the cage it is equipped with ballast compartments. The main ballast tanks are filled by gravity via drain holes equipped with ventilating valves with a remote control pneumatic drive. The balancing tanks are filled via kingston valve. The water from ballast compartments is replaced by compressed air (5-10 kg/cm3), supplied from the service boat compressor (min. 150 l/min). Air to the actuators is supplied through the pipelines made of corrosion proof steel and rubberized hoses. The process of submerging and surfacing is supervised by the depth sensor, its display being located at the service boat or via water acoustic communication channel from the shore.
The signal buoy consists of cylinders of variable sections, providing a platform for deployment and protection of the control and monitoring complex of the cage. The size and weight characteristics are adjusted to provide survivability in the regime of extreme weather conditions. It can operate afloat at wave (force 8-9) and respective wind speed. It also can freeze in ice (up to 50 cm) to stay for winter. Flexible pipelines and electric cables coming from the signal buoy to the cage and supplying compresses air and providing power supply. Additionally the buoy includes the antenna for an underwater acoustic control and monitoring system with an operation range of 10 km. Safety is provided by flashing beacons and corner reflectors, also from the feed bunker.
To install the cage at the water area (in a depth of up to 50 m), it is equipped with a special system of anchorage, consisting of anchor ties (i.e. a chain with a variable running mass) and 3 anchors (weighing 3-10 t), providing reliable functioning of the system under weather conditions given. The anchors are not included in the delivery, but are made on site (by the customer according to the drawings given). The anchorage system is designed for each particular site depending on hydro-meteorological conditions and depth of an installation site.
The net chamber with a volume of 1.000 to 2.000 m3 is preferably built from our polymer covered polyester net (mesh size 20, 25 or 40 mm) but could be changed to a kapron or nylon net too. The net chamber is placed within the steel structure at special guy ropes, running up and down from the platform. The guy ropes are fastened to the feed bunker and the net chamber. To provide for harvesting of fish, the net chamber is equipped with a device, consisting of a rope system and portable hand operated winch, raising the bottom edge to the surface. To remove wastes from the net chamber it is equipped with a special tray device which is lifted to the surface by the help of winches.
It is possible to position the cage system in a depth range in the water column of 4-40 meter. Afloated the system withstands waves (with personnel to force 3) without personnel to force 6 and waves up to 6 meter. Submerged it is resistant to force 9 and respective wind speeds and waves up to 8-9 meter. The axial diameter is 20,12 meter and the light displacement is 16,2 tons. Total height (including 2.000 m3 net chamber) is 12,1 meter, the minimum draught (at launching) is 0,8 meter and the maximum draught (including 2.000 m3 net chamber) is 8,6 meter.

We also produce traditional square cage systems of any size, based on our pontoon system.


SUBMERGED ILLUMINATED NET CAGES for the fingerling production with natural zooplankton

20 years' experience in the field of global plankton research and fingerling production with natural plankton and years of tests under different environmental conditions in marine and fresh water, are the basis of the new "UWG- Solar cage system". The production method is based on plankton feeding in the natural environment like: lagoons, bays, fjords, lakes and large ponds, by means of attracting the organisms using a lamp located in the centre of fine meshed submerged nets. Mainly Copepods and Cladoceres - but also a variety of other zoo plankton are photo sensitive and steadily swarm into the cages towards the light source.

Illuminated submerged cagesystemThe net cages 2x2x2 m (8 m3) are manufactured from highly resistant mono filament polyester fabric (with mesh sizes 0,3 to 1,8 mm), is fitted with a zipper for easy access and a conduit for the electric cable. The net cage is stretched onto a strong stainless steel or aluminium frame. An efficient solar generator is supplied for remote site operation. An electrical transformer can be supplied in order to reduce voltage to safer levels for use with water. Depending on the zoo plankton populations, the fish stocking density (from the fry stage to fingerling size of 5 cm length) can come to 5.000 Ind./m3 and survival rates of more than 90 % have been achieved with various marine and freshwater fish species.

Operation and maintenance is limited to: the functional control of the system, a periodic cleaning with a portable high pressure cleaner, in order to prevent clogging effects caused by detritus, algae and faeces, and the observations of the plankton development in the location. The system is environmentally safe since: no feeds or fertilizer are applied, the construction materials are inert, and the plankton consumption is minimal and does not affect the natural stocks.

PRECISION CLOTHS for aquaculture and hydrobiology

Plankton nets in use Copepodes under 500 micrometer cloth

This fabric program includes precision sieves of different material strengths and offers a narrow mesh grading between 20-2000 micrometer and therefore fulfils all requirements of today's aquaculture and hydrological needs. Appropriate sieve fabrics are offered per running meter and as standard or customised products, such as filter-, dip-, hatching-, cage- and plancton-nets.
In Austria a catch of zooplancton for the production of fry and fingerlings is commonly practisized since more than 50 years. During the last years several important optimisations are archived allowing a better net construction and easy catching. With appropriate designed plancton nets, harvests of several tons per day can be achived. Thank's to this Austrian development of special sieve-net-systems, it is possible to grad the plancton in 3 different size classes during the catch. The result is the correct plancton size for all development stages from fish larvae to fry and fingerling. An expensive and complicated indoor-production of prey organisms (such as: Algae, Rotatoria, Artemia, Daphnia etc.) is not necessary.

Recirculation Systems

The requirement for seafood continually rises worldwide, and product is continually becoming more scarce. Aquaculture is a young, innovative part of economy with high growth rates and secure prospects. The future of fish production requires water to be used as economical as possible, and environmentally safe removal of waste products with lowest possible energy consumption. Demands of environment legislation reduce possibilities of open water fish production more and more. Already existing fish farms are confronted with directions for purification of their waste waters.
This accelerates the development of intensive, water saving systems for fish production which do not depend upon natural environmental factors. Production in a closed water systems offers more a compact growing environment for fish, low shared personal costs and good profits.
In such systems the waste water, which is loaded with metabolic by-products, is recycled through biological and physical purification and more than 90 % re-used. Through improvement of the re-circulation and filter technique we are able to offer an very efficient, easy and cost effective system for fresh and seawater. Risk minimization, process control and fish health are factors considered in our designs and re-circulation systems are produced in module-construction. Each module is an autonomous working system and is therefore the water is not transferred between modules. Depending on system size and customer wishes our systems will be supplied with modern measuring, regulation and security technique and working accessory.
Depending on the requirements (production capacity, conditions and species) we offer generally two systems:

RECIRCULATION SYSTEMS for nursing and holding

The modules for nursery and holding are available for a yearly production-capacity of 1-2 t (125-250 kg standing crop) and consists of 2 square and 1 filter tanks with the needed technique and equipment. The water from the fishpools are cleaned through a particle filter to remove suspended solids prior to bio-filtration. The bacterial settlement for nitrification will develop on the packages of the reactor, mud will be removed through the current. Our bio-reactors have the gigantic settlement-area of over 900 m2 per cubic meter filter material and therefore we need only very small filter units. Through the introduction of fine air bubbles through a special aeration- and lift construction our systems work without pumps and therefore require less energy thereby reducing costs. Through compact construction, our systems can be installed any time and anywhere without rebuilding or extension expense.

Recirculation System

RECIRCULATION SYSTEMS for the intensive production

The modules for production are available for a yearly production-capacity of 50 t/year (standing crop 10 t) onward and allow our customers to get familare with the technique and topic without high risks. The water from the fishpools are cleaned through a drum filter to remove suspended solids prior to bio-filtration, where the nitrification process and the aeration with oxygen takes place. From there the water is pumped to the fishtanks, wich could be adapted to customer wishes in form, size and number. The use of UV- or ozone is planned. This system is available for all fish species (also salmonids). Beside consulting and planning we offer also training and service as well as the seed (fingerlings) etc.


HOLDING AQUARIA for fish and seafood

Holding aquariumAn aquarium should be seen as a complex grouping of elements functioning synergetically to maintain constancy of environmental characteristics, countering any variation whatsoever and simulating as far as possible the whole biological cycle that is present in nature and indispensable to the live of the aquatic animals. This professional range of aquariums are designed for holding of live crustacea or fishes at a working temperature of 10-30 °C and consists of double glass walls in which the two layers of glass are separated by a dry air gap. The aquaria are delivered as complete assembled units (IP55) with support frames (80 cm high, colour: black, white, grey or blue) with cover and lights, external mechanical/biological filter, protein skimmer, circulation pump and chiller with thermostate and UV-C.

The following models are available as standard:

Holding capacity kg 70-140 110-220 150-300

Larger or stackable holding tanks, on request.


POLYESTER TANKS in all forms, sizes and colours

Circular basins in all sizes and forms! Rectangulare tanks in all sizes and forms!

A long proven history (30 years) in pools and tanks manufactured of (GRP) glassfibre reinforced polyester (450 g/m2). The conical form and funnel shaped outlet and absolutely smooth inside finish ensure the system is practically self cleaning. Therefore it is possible to hold sensitive bottom fish or fish larvae. The whole pool and especially the edging very strong, allowing attachment of automatic feeders or other equipment.
Optional laminated feet make it possible to place the pool safe on any bottom and ensure easy lightweight handling or transportation. The pools and tanks are available in different sizes and types. The outlets are made from PVC - pipe (110 mm Ø) with water level regulation, which is fixed under the bottom and leaded at the pool side.


CIRCULATION BASINS for better production conditions

Circulation basinOur completely new developed "Circulation Basins" are between a rectangular tank and a circular pool. They summarize all advantages of both (i.e.: self cleaning, good flow conditions), but don't have their disadvantages (i.e.: bad water exchange, bad fish distribution). We recommend our new basins specially for recirculation systems to offer better production conditions to the fishes and to use the water more economically, but also for space and current loving fish species (i.e.: Salmons, Sturgeons).
We recommend a width/length relation of 1:3. Every basin has therefore two bottom outlets and should have also (two) inlets, thereby. A central seperator (middle wall) divides the basin in an endless canal.
We offer various models from our "Circulation Basins", which are made from Glassfibre Reinforced Polyester (GRP) and are available in all colours of the RAL-scale.

PRESSURE FILTER with cleaning technique

Pressure Filter UV-CThis compact prssure filters with integrated UV-C lamp (9-11 Watt for up to 9.000 hours) are complete filter systems with ecological threefold operation technic (mechanical/biological/optical), to solve all filter problems in garden ponds or aquarium tanks. An integrated user friendly backwash system allows an easy maintenance without opening of the filter. The water leaving the filter has the same pressure as the entering water and therefore may can also used for waterfalls or injectors and therefore provides for a better oxygenation. The filters have a diameter of approx. 27-37 cm and a height of 47-57 cm. They can stand free or set into the ground, below or above the water outlet and used for fresh- or saltwater. The filters are available in two sizes with a volume of 25-30 l and 1" hose connections, for a recommended water flow of approx. 2.500-5.000 l/h and tank or pond size of 3-6 resp. 6-12 m3 (with resp. without fish stock).

FILTER CHAMBERS with swirl seperator

Center-Vortex-FilterThis new compact filters are used specially for holding units and garden ponds and are very effective for the fine and raw filtration. The system can be operated by gravity or pumps and can be placed into the ground or stands free. A long inlet opening secures that the water in the vortex rotates slowly, so that the larger waste particles are traped in the center of the bottom. The build-in flow channels force the water to flow trough the filter media (i.e.: Filter brushes, Japan matts, Sinter glas, Aqua rock, Bio balls, Poly foam etc.). The waste particles concentrate at each cone, where they can be removed reularely by opening of a gate valve. The models are made from galssfibre reinforced polyester (GRP) and are delivered with cover and outlet pipes. They are available with or without filter material.

PROTEIN SKIMMERS for aquaculture and aquaria

EiweißabschäumerThis protein scimmers have a good dimensioned volume of the reaction- and foam tube. A special injection unit generates a vacuum, where air is succed in and distributed in fine bubbles. In seawater the single bubbles have a volume of 0,065 mm3, a surface of 0,785 mm2 and a diameter of 0,5 mm. Each liter air generates therefore a total surface of 12 m2. A rotating (patented) nozzle system cleans the foam tube and the foam collector. Over a valve (optional automatic) water cleans the nozzle sytems. A regulating system allows to operate the scimmer also under extreme differing situations of water column.

The optimal retention time is about 2 min., if the flow rate is increased the retention time decrease.

WATER DESINFECTION with UV-light

UV-system in stainless steel reactor  UV-system in concrete cannel

Ultraviolet light (UV) destroys microorganisms by changing their genetic information (DNA), but does not produce residual or hazardous by-products, nor does it affect the tast, odor or colour characteristics of the treated water. It is light with very high energy levels and wavelength of 200-400 nanometer (nm). The most effective ultraviolet light for desinfection is UV-C (200-280 nm), specially with a wavelength of 254 nm.
The heart of the UV systems are high-performance spectrotherm lamps (low pressure technology) which provide a stable UV output through a wider temperature range. This special spectrothermal lamps show higher degrees of effectiveness and stability than other conventional lamps. They also exhibit a high UV power output (up to three times more than competitive low pressure lamps) and long operating live (12,000 h), resulting in decreased overall costs. The efficient lamps have a high UV emission in the area of the effective wavelengths (254 nm), that makes it possible to destroy more than 99.99% of all pathogens in water. To further increase efficiency, reliability and service lifetime, electronic power supplies (ballasts) for the lamps where developed. In addition, the new electronic ballast replaces several components required in conventional systems, reducing overall electrical cabinet size and heat transfer requirements.
Electronic controllers containing smart chips are designed specifically for the lamps and increasing effectiveness. These can vary the supply of energy to the lamps as a function of water quality and flow rates. They ensure that optimal levels of ultraviolet rays are emitted in the effective wavelength range and at the same time, they ensure low energy consumption. Consequently the lamps have much longer life expectancy than conventional lamps. In addition, calibrated sensors, monitor and document all factors necessary for desinfection and provide superior wavelenght selectivity (>99% at 254 nm), minimal drift (± 2%) and long service life. Upon reaching a present limit, the UV systems automatically signal that cleaning is necessary. If required, additional functions, such as ultraviolet dose indicators, automatic cleaning and remote monitoring via telemetry and the internet, can be integrated.
By studying various reactor geometries with respect to the UV intensity distribution and hydraulic characteristics, specific reactors types where developed to provide effective desinfection while minimising overall power requirements. Our systems have a modular design, which enables us to draw up solutions that are specified to our clients' needs in all areas of ultraviolet desinfection for up to sereral m3/h. This systems are characterised by their high desinfection performance, combined with compact construction and low energy consumption. Depending on the application, also special ranges are available that can be easily integrated into existing systems. The control panel indicates and measures important operating parameters such as UV intensity (mW/cm2) in the water. Alternatively, the UV dose (mJ/cm2) can be calculated and displayed if a flow signal is provided.

Aeration Systems

INJECTION AERATORS for aeration, circulation, destratification and oxygenation

Injection Aerator Injection Aerator in use

This injectors are one of the best and most advanced aeration systems worldwide, and also suitable for large ponds. They work with an for endurance run produced, maintenance free, turnable, submerged (also seawater resistant), motor in different power sizes (1.0 HP 230 V/50 Hz or 1.5-2.0 HP 380 V/50 Hz). The rotating propeller (2800 r.p.m.) produces an adjustable current, through which air drawn from the surface and formed into fine evenly distributed bubbles.
The diffused air aerate from the bottom up and the circulation created from the fine bubbles displaces the surrounding water, thus breaking up stratified water areas. This constant surge forces the pond to turn over, bringing cooler bottom water to the surface, where it picks up additional oxygen from the atmosphere. Therefore the dissolved oxygen is always as high as possible. Through the eutrophication process (of faeces and feeds) there is usually oxygen deficit at depth, therefore this system works to an adjustable depth and introduces the oxygen where it is needed, not only on the surface. If submerged, pure oxygen instead of air can be introduced with exact dosage. Long contact time of the fine bubbles in the water, ensures also this system is very effective.
Depending on power and depth, the air flow rate is up to 35 cubic meter/hour and the oxygen introduction up to 3 kg/h/kw. At an oxygen content of 6 mg O2/l at beginning, one 1.0 HP unit in use with air, introduce over 0.32 kg O2/h which is the oxygen demand for over 2600 kg (table sized 250 g) trouts at a water temperature of 10 °C, for approx. 1000 kg at 20 °C or up to 3000 kg of other species.
Depending on installation, depth and current, sediments can also be cleaned. If the aerator is positioned near the water surface it also acts as an ice clearing machine in winter. Strong circulation also eliminates pond stratification and organic matter deposition. Finally thanks to the floatation phenomenon (foaming), this aerators make it possible to remove excess algae proliferation, colloidal substances, mud and any other suspended particles and improve water quality. With this proven system, all variants of aeration, current creation and oxygenation are possible.
Theese proven aerators are made in China and are supplied complete with motor, supports, float kit and propeller protection fingers, but are not available for delivery to: Portugal, Spain, Italy, France, Belgium, Danmark, Germany, Great Britain, USA, Mexico, Thailand and Taiwan. They are lightweight compact systems (Motor: 14 to 16 kg), and very easy to install.


INJECTORS without further energy consumption

Injector Injector in use

This "ECO" injector is a new developed static aerator for the water inlet pipe (1 ") in tanks, raceways and small ponds, that works hydraulically and has no moving parts. It is designed to ensure cost-effective use of any viable water source. For degassing, aeration, oxygenation and dosing with chemicals (thereby avoiding the slightest wastage and maximising efficiency). In enriching the water with air or pure oxygen, this aerator can create good circulation with a lesser ammount of water than is usually supplied, with consequent energy savings. It works hydraulically (from 0.2 bar and 0.4 l/sec. on) exploiting the act the water passing through it at high speed (achieved by means of suitable flow rates and pressures with the special 3 interchangeable nozzles (for approx. 30, 50 or 100 liter/minute) and creates a great pressure drop and consequently a tremendous suction capacity, without introducing additional energy. If no pressure is available it can be connected to any pump.


PROPELLER AERATOR with horizontal spray pattern

Propeller Aerator in useThis propeller aerator was specially developed for intensive production of fish in tanks, raceways and ponds. The maintenance free, heavy duty, motor (230 or 380 Volt) has a mounted propeller which allows a high water circulation and has an oxygen transfere rate of approx. 1.5 kg/kwh. The small float size (70 x 70 cm) as well as the compact and lightweight system make it fast and easy to install.

PADDLEWHEEL SYSTEMS for effective oxygen introduction

Aeration and/or oxygenation is specially of economic importance in intensive farms. At this completely new developed systems all possible failures and defects of other known products have been removed. The systems have been tested under hardest conditions and have a very high effeciency, with the same time low investment and operation costs. The oxygen introduction is usually about 1.6 kg/kwh. There are no bearings of the wheel (100-130 r.p.m) necessary and also no couplings and discs, this reduce friction lost and increase the effeciency and also reduce the possible parst which could become deffect with time. A very long self live and high efficieny is also guarandeed through the worm-gearing. The motor is specially sealed aginst moisture. Paddles, wheel and frame are made of stainless steel, the floats from thick UV- and ozone resistant material. The Paddlewheel Aerators are available in different power ratings (180, 250, 370, 550 and 750 Watt) and have dimensions of approx. 1.5 x 1.6 x 0.6 m (LxWxH) and a weight of 30-70 kg.

Paddlewheel aeratorOxygen cover

To use this paddlewheel aerators also with pure oxygen instead of air, as accessoire a special oxygen cover is available. The special formed cover inside guarantees that no oxygen (feed up to 15 l/min) disperse or waste to the surface, after the water leaves the aerator. As there are no seals necessary at the bearing of the wheel, also this guarantees that there is no oxygen wasted and thus this makes the system very effective too. The efficiency is up to 90 %.


RUBBER DIFFUSER with stainless steel frame

Rubber Diffuser in stainless steel frameThis professionell, extremely durable and effective diffusers are suitable for the live fish transport and for emergency purposes with pure oxygen. The approx. 1000 pores/meter arranged in 6 rows, of the special oxygen hose open only if oxygen is supplied and close again if the supply stops. Thus, pore blockage is prevented and the diffuser is allways ready to operate. An uniform bubble size due to the streight hose mounting in a stainless steel frame are main features of this professionell diffusers. The sturdy hose connection is 6 mm as standard (and is also available in 9 mm if prefered).

The following sizes are available as standard:

Width cm 40 40 55 55 55 55 70 70 70 70
Length cm 50 70 70 80 90 100 80 100 120 150

Other diffuser sizes and forms on request. For the self production of diffusers we deliver also just the diffuser hose per meter (19 mm inside diameter) as well as end pieces with connector and the pressure hose per meter (6 mm inside diameter).


CERAMIC PLATE DIFFUSERS for micro gas bubbles

Micro Bubble Ceramic Oxygen Diffuser Micro Bubble Ceramik Oxygen Diffusser in use

This diffusers are robust engineered products with high specification and performance and perhaps are the most efficient diffusers available. The ceramic plate has been designed to be very strong, the thickness (approx. 12 mm) of the ceramic has been increased over the more conventional plates. The pore size is also only 0.3 microns which produces a cloud of tiny oxygen bubbles (10-200 microns) in the water. Depending on the gas (oxygen or ozone) and water chemistry, the diffused gas may pass directly into solution with no visible sign of bubbles. There is no better gas diffuser available.
The flow is optimally 3-4 l/min and maximally 6-8 l/min. The working gas pressure is 25 to 35 psi, do not exceed 50 psi as it may result in damage to the diffuser. The ultimate in flat plate ceramic gas diffuser. One diffuser will supply sufficient oxygen to supply 100 % of the oxygen demand of approximately 2000 kg of fish with an efficiency approaching 100 % transfer of oxygen into solution and a oxygen satturation in the water of over 120 %. In seawater applications it can actually be difficult to see the bubbles, since the gas goes almost directly into solution.
The ceramic flat plate diffusers has a weight of 3,55 kg, outside dimensions of 450 x 110 x 28 mm with a ceramic plate of 400 x 90 x 12 mm (360 cm2) which gives a very small bubble size and are used where a small high rate diffuser with a high oxygen transfer efficiency is required. The diffuser has 4 mounting holes where stoppers can be fitted and has a female BSP threaded inlet with 6 mm adapter to connect the pressure hose.


PROFESSIONAL CERAMIC DIFFUSERS for airCross-Diffuser (floating)

The fine poored ceramic tubes allow to diffuse the air in fine bubbles. The diffusers should be installed in the same deepth, but as deep as possible below the water surface. The floating cross diffuser is placed on the water surface in the center of the tank or pond and fixed with a rope to the shore so that it can move a little and aerate a larger area.

The cross diffusers are available complete with 20 mm hose tail (other on request) and are delivered with or without float. The 1 m long feeeding tube is also available shorter. Each diffuser tube has a length of 18 cm and a diameter of 6 cm and can introduce approx. 1.5 to 2.0 m3 air/hour each (6-8 m3 per cross diffuser). They are also available as self sinking single tube diffusers with hose tail.


FLEXIBLE GAS DIFFUSERS with high performance

Flexible Gas DiffuserThis is among the most robust and versatile fine bubble diffusers commercially available. The diffuser has the capacity to pass large quantities of air, oxygen or carbon dioxide with low pressure drop and small bubble size (approx. 1-4 mm). Fine bubble diffusion is inherently more effective than coarse bubble diffusers in providing a greater mixing action and aeration efficiency. The diffusers are of a tubular semi-flexible construction (32 mm in diameter). An outer polyester sleeve encases a silica particle ballast and an inner nylon distributor. The internal ballast is not fused together, therefore precipitates such as iron and carbonates tend to crack off, and can be flushed out easily. The internal ballast (weight approx. 1.6 kg/m) means that the diffuser does not need to be anchored to the floor of the tank. The unique design of the diffusers makes them largley resistant to biological and chemical fouling. The diffuser resolves many of the problems associated with other diffusers and has proven itself with over 10 years of use in many industrial and wast water treatment applications and it is the leading air diffuser for aquaculture. This gas diffuser is a hybrid air diffuser with the benefits of both tubulare membrane and solid air diffusers, but with few of the disadvantages. Solid diffusers can breack or become blocked by biofouling, iron and carbonate precipitation. Membrane and other tubular difussers have to be secured to the tank bottom. The membranes (elastomers) can also suffer from fatigue, and as a consequence the performance can rapidly tail off over a few months.
The diffusers are sized (up to 5 m in length) according to the flow (m3/h) of air to be used. Length is approx. 33 cm per m3/h air or liter oxygen/min flow rate and pressure drop is less than 1 psi. All diffusers are supplied with either 3/8", or 1/2" hose tails in acetyl plastic. Brass or stainless steel fittings and non return valves are also available.


MEMBRANE COMPRESSORS for Direct Current

Membrane CompressorThis simpe membrane diaphragm compressors supply oil-free air and are perfectly suitable for live fish transports, where the required energy (12 V/DC standard, 24 V/DC on request) can be supplied by a battery i.e. from the truck. As accessoires 6 mm hoses and various diffusers are available.

REGENERATIVE BLOWERS for pressure or vacuum generation

Regenerative Sidechannel Blower (doubble stage)This reliable and favorable blowers summarise modern know-how of pressure and vakuum generation, based on longtime experiences. The motoris constructed for endurance run is available in various power sizes. Concerning the compact dimensions and the low sound this blowers are easy and everywhere to install. Lateral channel blowers work regeneratively. Casing and impeller with radial blades form a circular body. The medium (air) is accelerated by centrifugal force in the blade channels, stocked and compressed. This process continues permanently with continually increasing pressure rising until the medium leaves the casing through the outlet connection. Because of the special principle of construction and design, there is no contact between rotating parts.
Our unique submerged air blowers (on request) are installed directly in the water and allow therefore shorter pipe-lines, resulting in lower oppositions. This submerged blowers are nearly noth to hear and also save space. The waste heat from the submerged blowers can be used to heat the water in warmwater recirculation systems, which is an additional advance. The blowers can be installed single, paralell or for increasing the pressure, also in rows. At special request, all blowers can be produced for seawater use or other electric frequencies.

SATUROMETER to identifie gas super-satturation

SaturometerThis new handheld saturometer (Protection class IP65, with electric backlight display identifies gas super-saturation in water reliably to 400 hPa resp. mbar pressure difference, with an accuracy of 1 hPa. It works with a usual 6 x 1.5 Lithiumcells, with integrated capacity monitoring on the meter. The maintainance free sensor is copleatly sealed (Protection class IP67, Signal outlet 0-5 V). As option also an oxygen sensor can be connected to the meter.
The gas bubble disease is very often present undetected and leads to significant damage in the fish stock. If fish are being exposed to oversaturation continuously, they will suffer from it no matter which gas contributed most to the supersaturation! In experiments it was proven, that a continuous charge with only low levels of supersaturation has a significant negative impact on the fish immune system. A fishstock infected with IPN (Infectious Pancreas Necrosis) produced losses of 10-15 % after 90 days whereas fish from the same stock epxosed to supersaturation showed a mortality rate of 65 %. The gas bubbles themselves cause a lot of direct damages like lesions and embolies. Those alone are lethal in some cases. But in every case they open the door for secondary infections which can not be repelled by a weakened immune system. Another typical sample is a trout breeder who reported fin rot and saprolegnia on the fish body. Measures showed a gas pressure of 45 hPa which equaled to 105 % gas saturation. It may not sound high but the pectoral fins were severely damaged by gas bubble lesions. The fin rot and fungus (Saprolegnia) were clearly produced by an undetected gas oversaturation.

We deliver also moisture meters.

Dynamic Sensor Data


MULTICHANNEL PROCESSERS for control and management

Automated monitoring and control removes the information gap that exist with manual data collection, lower labour costs and allow to operate the aerators exactly then when they are needed. One of the biggest advantages of automated monitoring is that it provides critical data continuously and reduces the chance of human errors. Continuous monitoring and control maintains the environment ideally suited for optimal fish growth and production, and reduces the stress in both fish and workers. Traditional metering and monitoring equipment keeps dissolved oxygen levels within certain fixed limits. This system enables to vary oxygen levels as desired, to suit the fish, the feed and the time. The desired levels have just to set and the system will automatically ensure that the orders are carried out. The optional extensive logging facility store data, so that every time it is to see what happened and changes can be made if needed.

HaupteinheitThe main unit is a small yet powerful microprocessor controlled system, and is build on a modular basis. It accepts up to 8 analogue inputs (i.e.: for oxygen and temperature), and has galvanic isolated control and alarm outputs (4-20 mA). The system performs measurement, alarm and regulation functions ensuring safe operation, maximum feed utilization and livestock growth. Optionally the system can be extended to a powerful registration and data logging tool, where a PC can be connected, from which observation of records and copying or logging of data can take place. It is a stand alone unit that does not depend on a PC for correct operation and can operate (and be configured) without a PC. The unit can also be connected to a 24 V battery pack to ensures that the system remains operating after mains failure. The compact system is built into a plastic box (dimensions 36 x 15 x 31 cm) and has a weight of just 5 kg (Protection class IP 55/Nema 4).

The robust and easy to use (60 mm large) oxygen probe is a self polarising membrane covered galvanic cell that generates an electrical signal proportional to the oxygen pressure it senses, no matter whether it is in water, air or another medium. It is connected using ordinary 2-core cable, which can have any length (up to 1000 m) and does not need an external supply because it makes its own electricity. Cleaning the membrane (with a cloth or tissue) is, apart from an occasional calibration, the only routine maintenance necessary.


CAMERA SYSTEM for underwater monitoring

Underwater CameraThis small waterproof (IP68) camera can be used down to a deepth of 30 m  The compact form with just 11 cm in length allows to use it everywhere. The modern camera technic (1/3" Sony Super HAD CCD incl. 3,6 mm objective, view angel 78 degree, 291.000 pixel, resolution 420 TV-lines) allow to use it even under diffused light conditions (down to 0,01 Lux) and still supplies usable images. Above 2 Lux the camera supplies perfect colour pictures, below 2 Lux it switch automatically to b/w operation. The use and installation is very simple, just connect the plugh of the camera to your vieo inlet of your TV and connect the cammera to the electric circuit. By an USB Digital-Recorder box (available as accessoire) it is also possible to display images of up to 4 cameras simulanously (manually, timed or via sensor), or to transfere it to a PC to view, or store it. The camera can also be used year round (temperature range -20 to +55 °C). The camera is delivered with turnable base, transformer (230 V AC/12 V DC), BNC/Chinch-Adapter, as well as 30 m cable (longer cables on request).

Breeding Systems

FISH HATCHING JARS made from plastic

Plastic Hatching JarUsed successfully for over 20 years by federal, state and professional hatcheries and fish producers here and abroad, this jar can be used for a wide variety of species like: Salmonids, Thymallids, Coregonids, Acipenserids, Percids, etc. Made of high impact, non-corrosive easy to clean plastic, this uniquely designed hatching system enables uniformely distributed water to rotate fish eggs ever so gently and evenly. It works very simply as water from the supplying hose is directed down to the open-ended feeder tube in the center of the jar. The tube (diameter 3 cm = 1.25 in.) easily accommodates the prefered water flow so that the eggs at the base are rotated uniformely and precisely. The jar has a height of 45.8 cm (18 in.) a diameter of 16 cm (6.25 in.) and a volume of 6.86 l (232 oz.). It weighs only 2.5 pounds and can be ordered complete or also without feeder tube and screen. A circular filter/mesh screen (as acessoire) prevents waste eggs from spilling out of the jar, while the large spout (length 7.5 cm = 3 in., width 5.3 cm = 2 in.) at the top lets hatched fish swimm out at just the right time. Now you can virtually duplicate nature's way of hatching eggs with this durable, seethrough incubator jar. So next time you want your eggs "over easy", make sure you are using this hatching jar.


Zuger Jar SystemZUGER-JAR-SYSTEM made of stainless steel

This systems are made of stainless steel and are equiped with 8 liter glass jars wich can be removed and supplied seperatly. Through the inlet tank, all jars can be individually supplied with water.

The standart system has 7 Jars each with a volume of 8 liters, other sizes or jars are also possible, depending on customer design. Single jars with or without support are also delivered.

The system can be equiped with a heating-/cooling system and in connection with an UV-sterilizer operated in recirculation.

We deliver also traditional troughs made of reinforced glass fibre polyester with (40 x 40 cm) egg incubation baskets.


Vertical Incubator with 8 traysVERTICAL INCUBATORS for salmonid eggs

The vertical incubators guarantees safe rearing conditions and is available with 4, 8 or 16 trays approx. 60 x 60 cm (for 50.000, 100.000 or 200.000 eggs respectively up to 1 liter eggs per tray) made from strong non toxic plastic material and includes the aluminum frames (approx. 44, 82 or 175 cm high) and all egg trays (approx. 50 x 40 x 4 cm) with PVC coated polyester screens. Optional an isolation panel (clear or black) is available.
This incubator for the professional breeding and hatching of eggs and fry can be combined and arranged in different ways, to utilise the water and space as effectively as possible. The water (approx.
0.1-0.2 l/sec) from the inlet, flows through the trays on which the eggs stays, and leaves the water tray over the front during the side canals to the next tray, were it flows again through the egg tray and so on, so that all trays will be supplied with sufficient oxygen. Without disturbing the other trays, each tray can be drawn out and controlled easily.


BREEDING THROUGHS for salmonid eggs

Dreeding Through with 4 traysThe horizontal throughs allow an easy survey of the breeding process and are available for up to 4 or 7 baskets approx. 40 x 40 cm (for up to 1-2 liter eggs each) made from smooth reinforced glasfiber polyester (approx. 215 or 360 cm long). The stainless steel screen (1.5-2.0 mm holes) of the egg incubation baskets are fitting exactly. Optional an outlet screen is available. This throughs can also be used for startfeeding of the fry after the yolk sac has been absorbed. The water (min. 0.2-0.4 l/sec) from the front, flows through the baskets on which the eggs stays, and leaves the through at the back side, so that all baskets will be supplied with sufficient water. Without disturbing the other baskets, each basket can be controlled easily from the top.


BREEDING BOX for running waters

Erbrütungsbox (geöffnet)An experience of many years in egg incubation and fry rearing, as well as stocking experiments in various waters, where the base of this new and innovative invention for the hatching of salmonid eggs in natural running waters. The flood save and closeable box is made of stainless steel with dimensions of (LxWxH) 85 x 20 x 12 cm, weight approx. 8 kg). It is used for the professional and controlled incubation and hatching of salmonid eggs as well as for the breeding and rearing of fry for (re)-stocking purposes. The box is simply set into the water (front flap against the current and cover a little above the water line) and anchored by the eyes to the bottom ground. Depending on fish species and egg size, the box supports a save environment for up to 10.000 eggs and fry until exogenous feeding. The eggs lay in baskets, which can be fitted with special hatching substrate to reduce maintenance. Under „normal“ conditions, the maintenance is limited to the periodical controll (1 x per week) of the system, where results of 90-95 % are reached in average. When the fry reach the stage of exogenous feeding they can distribute themselve in the brook or river.


HATCHING SUBSTRATE for stronger fryHatching substrate

Mainly for salmons, but also for many other salmonids, this 2-layer hatching substrate (40x40 cm) have been used and proven well. The eggs are incubated on the hatching substrate as usualy practized. After hatching the larvae move trough the spaces and shelter in the substrate nipples of the soft rubber like plastic substrate. The hatching substrate imitates the gravel substrate naturaly occuring in the brooks or rivers and provides optimal developmental conditions for the fish larvae. The fry are therefore stronger, have less deformations and a lower mortality rate.


Egg pickerMANUAL SORTING DEVICE for salmonid eggs

Formerly, developed at the Austrian Institut of Fisheries Economy in Scharfling, this handheld egg-sucker has been rebuild, allowing to select dead Salmonid eggs now easily and fast.
The pistol-formed device has to be hold at the handle with one hand, with the other hand the sucktion ball has to be pressed until the unit overflows at the tube end. Now, each egg can be avised with the sucktion pipe and if the button at the handle is pressed, it will be sucked into the plexiglass collecting unit.
With some experience, it is possible to work with this device fast end exactly. Where no automatic sorting machine is available, it is the best professional device for sorting Salmonid eggs manually.


AUTOMATIC FISH EGG SORTER with fiber optics and infrared light

 

Egg SorterThis egg sorting machine uses the most current technology to sort 100,000 eggs per hour. It is available with both live and dead egg counter or also without counters. Using the patented standard disk, the egg sorter will sort salmonid eggs from 5,000-18,000 per kg (150 to 500 per ounce), or if equipped with the salmon disk, it will sort any size salmon egg. Best of all, you never have to change disks to handle different sizes of eggs. The patented technology uses fiber optics and modulated infrared light to scan the egg and assure the highest level of accuracy (approx. 98-99 %). It has been used all around the world and will accommodate any local voltage. In the interest of safety and reliability, the local voltage is reduced to 12 volts DC. It has dimensions (LxWxH) of approx. 78 x 35 x 27 cm (32 x 14 x 11"), a weight of 23.4 kg (52 lbs), and an egg tank capacity of 19 liters (5 gallons) and is made of clear and white acrylic plastic.
Eyed eggs are placed in the trough with water flowing through the bottom. Several kilogram of eggs may be loaded at one time. The water flushes the "eyed" eggs against the patented disk where they are captured in the tapered holes in the outside of the disk. Once the egg sorter is fitted with the disk matching the type of egg you are sorting (trout or salmon) it will sort any size egg inserted. The eggs in the disk then pass an electronic scanning device which, using modulated infrared light, detects dead eggs. All with 100 % ambient light immunity. Dead eggs are then ejected out one side of the sorter while the live eggs travel to the opposite side where a gentle flow of air ejects them into a curtain of water which carries them to a separate container - safe, sound and ready for further incubation. The counters then increment, providing accurate totals of both live and dead eggs sorted. Each time a dead egg is detected, a light comes on giving you visual assurance that everything is working correctly.

AUTOMATIC FEEDERS for controlled feeding of dry food

Solaris - Standard, Interval, Superspreader and Electric each with 95 l feed hopper and tube holder

This Solaris Feeding System was designed and constructed to the latest specifications in the field of aqua culture economics by using the most modern components of present day technology.

The model "STANDARD" is delivered with a (600 mA) solar panel, which supplies a motor with the needed energy. This feeds without battery, without electronic, (some seconds, some seconds pause) from sunrise to sunset (also on rainy days). The daily feeding amount (1-5 mm Pellet) is adjustable from 0,1 kg up to 100 kg/day.

The model "INTERVAL" is also equipped with a feeding computer and accumulator (to balance weather depending days) which is mounted in a splash proof box (directly on the feeder) and can be adjusted exactly to feeding intervals, feed amount and time.

The model "SUPERSPREADER" is equipped additionally with an adjustable sector and round spreader (radius adjustable approx. 2-8 m and up to 20 m on request), and delivered with a bigger solar panel.

The model "UNIVERSAL" can additionally be used for fine granulated feeds and pellets up to 12 mm.

Thewhite or green feed hoppers are available in four sizes (for 15, 25, 45, 75 or 100 litre). As accessoire a tube or ring holder hopper support is available. Optionally we deliver a holder construction to fix the feeder on land or a floating construction to put it on the water surface.

All models are also available without solar panel, accumulator and timer, for the connection to a central power supply with transformer and distributor box (for up to 8 or 24 feeders).

For this central timer and distributor box we also provide special hatchery feeders.Electric Hatchery feeder incl. 2,5 l hopper

The model "HATCHERY" is a disc-feeder with a 2,5 l volume feed zylinder and was developed for feeding the finest fry food up to 2 mm pellets in the hatchery. The feeder is suspended above the fry tanks, thus allow you to have sufficient space to work. Power supply is provided via a distributor box equipped with a (220V AC/12 V DC) transformer and a timer. The beginning (i.e. morning) and the end (i.e. evening) of the feeding period are set on the timer. The distributor box automatically issues a pulse which switches the motors of all (up to 24) connected feeders on simultaneously for a short time to move the conveyor disk(s). The interval between pulses is infinitely adjustable from 0,1 second to 10 hours. For individual feeder dosage, the slot between conveyor disk and the plexiglass zylinder can be adjusted. For this purpose, slacken the adjustment screw (turn counterclockwise), turn the conveyor disk cklockwise (the slot becomes smaller), or turn it counterclockwise (the slot becomes wider), and inaly re-tighten the adjustment screw.


PENDULUM FEEDERS for self service 

Pendulumspreader with 75 l Hopper and Tube holderPendulumfeeder with 25 l Hopper and Ring holderThe model "PENDULUMFEEDER" is a self feeder for 1-5 mm pellets with a disc. When the fish touch the pendulum, the feed falls from the disc directly into the water. The slot between feeder and disc can be adjusted.

The model "PENDULUMSPREADER" is a self-feeder for 1-5 mm pellets with solar panel, which continously operates a spreader disc. When the fish touch the pendulum, a part of the feed falls directly into the water and a part of the food on the adjustable spreader disc which spreads it over a distance of up to 8 m (sector spreader).

The white or green feed hoppers are available in five sizes (for 15, 25, 45, 75 or 100 liter). As accessoire a tube or ring holder hopper support is available.

AUTOMATIC FEEDING DEVICE for frozen zooplankton

Planktonfeeder20 years world wide experience in the field of plankton research, catch and larval feeding are the basis of the new "Plankton feeder", which was developed with the Institute of Fish research.
This device is designed for the professional application of frozen zoo plankton as a larval diet in marine and fresh water hatcheries for the production of high quality fingerlings like: Coregonids, Chars, Grayling, Salmon, Sturgeon, Sea bass, Sea bream, Turbot, Grouper and other species. The technique is based on a timed "wash down" of feed layers from large frozen plankton crumbs (up to 20 kg) and homogeneous distribution of the thawed plankton rations to the larval tanks by a specially developed self cleaning distributor. "Wash down" of the food layers and thawing can be performed either through spraying or by flooding or by a combination of both facilities, the remaining plankton is frozen immediately. The feed particle size can be perfectly adjusted by a special sieving unit. In order to avoid membrane damage and leaching effects of the thawed plankton organisms, the feed is distributed to the (up to 32) larval tanks by gravity flow only.

If necessary we deliver also the frozen crustacean plankton or plankton nets in all diameters and mesh sizes.

ELECTRONIC COUNTERS for fry and fingerlings

Fry Counter Type MicroThis fry counters have been developed with particular emphasis on well-being of the fish. The counters operate according to the "free-swim" principle: the fry or fingerlings (0,2-70,0 g depending on species) are in their natural element all the time and swim through the counter unit by instinct. Thus the counting will in no way cause stress to the fish. The counters have patented nozzles that seperate the fish by means of water so that each of them passes the photoelectric cell - a simple and reliable way of counting the fry with 98-100 % accuracy. The counters are fitted with reliable electronic components with memory. The electronic cylinder operates on chargable batteries but may also be connected to 220 V/50 Hz. Sensor unit and electronic cylinder are both water-resistant. The counters are easy to use and to handle. No division according to size is required and only one person is required to operate or move the counter.
Each counter includes a stainless steel water pump (220-240 V/50 Hz, 940 Watt, 11 kg with a capacity of 12 m3/h), and frame to mount the counter on the edge of a tank or placing it in a tank or cage. As accessoire kits are available to count fry from 0,2-0,5 g and also flatfish.

PIPELINE COUNTERS for much fish

Fish Scanner with control unitThis fish scanners are based on a patented counting principle which gives both high capacity and accuracy (98-100 %). The fish flows freely through a pipe and passes an advanced camera/measuring system (CCD Camera chip) which will register the size and speed of the passing fish. The resulting data is then transmitted to a control unit which may handle as many as 4 channels (e.g. during grading) simultaneously. It is not necessary to have any space between the fish passing simultaneously. The robust and reliable electronics of the system will always provide the total number of fish passing through the unit. The splashproof counters are easy to use and suitable for direct fish pump or grading machine feeding. Optionally an easy-to-use PC software which will in addition to presenting the accurate number, give you all the information you need from the counters. It gives you real time monitoring with key features like: number, weight (average/total/distribution), speed, efficiency, Reg. Unit status, lens check, systems log and printing the results.

The control unit (dimensions WxHxD 28x13x37 cm, weight 5 kg) is made from powder-painted marine aluminium case which is sturdy, splashproof and user-friendly. The power supply is 100-240 VAC 50/60 Hz (consumption 10-33 Watt), 12 or 24VDC (150 Watt power inverter available as accessoire). The input channels can power and control up to 4 CSE or 2 CSF registration units at the same time. It has fluorescent buttons and backlit display, and also connectors for auxillary equipment like PC, and PLC control etc. The adjustable carrying handle can also lift the front of the control unit (to approx. 10º, 30º and 45º) for easy operation and a better view. As options an external siren (115dB) and a PC monitoring system (requires a COM-cable) is available. The control unit can easily be connected to a PC to monitor and log the counting.
The CSE-units are used for "dry"-counting (pipe 0-25 % full of water through the unit) and suitable for many applications.
The CSF-units are used for wet-counting (pipe 100 % full of water through the unit) and suitable for special applications.
All registration units are delivered with 10 meter cable, other lengths available on request.

ELECTRIC FISHING DEVICES with direct- or impulse-current

Electrofishing battery devices (250-10.000 Watt) Electrofishing backcarry devices (1.300-3.000 Watt) Electrofishing stand devices (3.000-13.000 Watt)

This save and powerfull electric fishing devices are sucessfully in use on all continents since over 20 years. Through the various and sometimes problematic areas of use, a wide range of devices was developed which will match nearly any requirement.
All devices are build to EN 60335 and EN 55014-standards, IEC and VDE-regulations, and can be TÜV-tested if prefered. The electric building corresponds to security class II. Therefore all power delivering parts are doubble isolated and guarantee the best possible security for persons. A "Totmannswitch" (in the European Union required) guarantees for additional security, so that all outlets of the device are without electric current if dangerous situations arrise. The permanent excited generator and the high quality magnet materials guarantee a continous and reliable power. Each device will be tested mechanically and electrically completely and delivered with user manual.
Dirrect current creates usually a better anodic reaction as impuls current would doe. But at extreme conductivities or for electric barrieres with dirrect current soon the borders are reached. As result, powerfull combinated (Dirrect-/Impuls-Current) devices where created, where the impulse frequenz and volts can be adjusted (via motor turns or switch). The backcarry units are compact lightweight systems with high outgoing power. Impulse devices are a little larger and have a little more weight than dirrect current devices.
We deliver net-, battery- oder petrol-driven backcarry- or stand-devices with dirrect- and/or impulse current with an outgoing power of 250-11.000 Watt (5-160 kw/impuls at 25-100 Impulse/sec.), and a current of 300-960 Volt with a weight of 10-135 kg and for a conductivity of 50-10.000 µS.
As accessoires are available: 30-50 cm Ø Stainlessteel-Anodes with RGP-electro handles up to 6 m in length, Copper-Cathodes with cable and connector, Plastic cable drums for up to 200 m cable, hand- or foot-Totmannswitch, Electro-rubber outfit (tested to 1000 Volt) as well as tanks and lights.

AUXILIARY FISH GUTTING DEVICE made of stainless steel

Gutting device (with washing table and rinsing brush)This gutting devices are in use since more than 20 years and a valuable help for small and medium processing plants. They allow to gutt and clean fish (like trout) from 150-1500 g in one rational working process, without give the fish out of the hand. There is also no need for turning over the fish in your hand as all sequences of operation start from the vent. If the operator should slip in the direction of the blade while cutting, an injury can nearly be excluded. The rational working sequences enables one person to process 300-400 fish per hour.
With the adjustable and save gutting blade the ventral wall of the fish is cut starting from the abdomen. As hygiene is the most important factor when processing fish, injuries of the guts are also excluded. The suction head has two scrape edges at its lower rim. While passing through the fish, all remains (like kidney and blood) are removed. By pressing a button, an automatic knive comes down and cuts the gorge, which is than sucked and stored in a (30 l) container. Optionally, after gutting the remaining blood is removed by the rotating (1500 RPM, 20 cm diameter) round washing brush.
Theese stainless steel gutting devices are delivered complete as table, wall or stand units with or without compressor and vacuumcleaner and with or without round rinsing brush.


AUTOMATIC GUTTING MACHINE with fish size adjustmentGutting machine 1700

This compact and robust fish processing machine (for trout and bass) is made from stainless steel and plastic material. A main point at development was the removement of complicated and failing technique. The complete machine operates without hydro pneumatic or electronic elements and is driven by hydraulic pumps, which are integrated in the frame. The machine is (except a mothly oil control at a viewing glas, and the exchange of knives and brushes) nearly maintainance free. Complicated and expensive engagements are not necessary and the function via a push button allows a rentable working. Additional misstakes are impossible as wrong size selection can be avoided with the automatic niveau-regulation. The running speed of the transport chain is as low as possible, to allow to feed the machine with the fish just by one hand. A control line at the outlet side allows an optic control of the processed result, without the need to take the fish in the hand. Bad results (usually approx. 5 %) can be removed here. As the machine works without cross-cutt between gillcovers and pectoral fins, there is no additional waste of fish weight.

As accessoire a 6 mm strong plexiglas cover (LxWxH: 84x50x29 cm) is available, under which the fish can be scaled to avoid spraying of scales during scaling.


AUTOMATIC SCALING MACHINES for many fishes

Automatic scaling machineThe robust, solidly constructed machines with belt drive offer perfect scaling technology, with their design (body in stainless steel, automatic time selector and control valve for reduced water consumption) and complete operational safety (auto-stop control, motor protection, restart protection).
Scaling takes place at the bottom and sides of the machine and offers the advantages of short (approx. 1-5 minutes per scaling cycle), low-noise scaling cycles and reduced water consumption. The water used in the scaling process is accumulated, so that the fish are thoroughly washed and a soft cushion of water is formed. This provides a flexible support and ensures that the scaling action is very gentle (fishes are not exposed to heavy bumps or impacts). The auto-stop control automatically stops the machine when the loading lid, top lid or release flap is opened. Gentle release is ensured because the machine restarts slowly and the start button must be pressed and held down, which is an added safety feature. An automatic shut down with manual restart guards against automatic start-up after a power failure. The scaling machines are supplied either with a karborundum drum for soft fisch or small scales and with a round-hole drum for clams and hard fish or large scales. The machine is also available with a dirty water drain on the left-hand side (standard at the right side).

FILETING MACHINE for some fishesFileting machine

This compact machine allow to fillet all fish with up to a height of 110 mm and a weight of 100-1000 g fast and exact, without gutting the fish. The machine is made of stainless steel and easily cleaned with water. A hight output (approx. 100-200 kg/h) and savety measurements allow a fast working. The compact design (LxWxH: 118x56x127 cm) and the low weight (approx. 88 kg) allow to use it on nearly any place.

With the rotating round-knife, first the head is cut off. Following, the fish is put in the machine head-cut first and belly-up. The fish is now forwarded by special grip belts to the round-knifes and 2 fillets are cut. The cut is adjustable, thus allowing a low waste of meat (Filet approx. 40-50 %). The belly bones have to cut of manually. The skinn can also be removed manually or by skinning machines. A continous cleaning is doen by water spray nozzles.

As accessoire an (20-40 degree) adjustable forwarding belt (30 cm/s, wide 35 cm, lenght 140 cm) is available.


FILLETING MACHINE for much fishes

Filleting machineThe transformation of fish into fillets offer an interesting value added profit margin and is directly depending with the filleting costs. This new generation of filleting machines now comes in different sizes, with dimensions suited to various fish sizes and species (Salmon, Trout, Charr, Whitefish, Perch, Pikeperch, Bass, Bream, Mackerel, Bonito, Tuna, Pollack etc.) permitting an efficient filleting of fish with minimum loss of product and high yield production of 50-80 % (Salmonids) of splitted fillets. The productivity depends on the operator skill and process chain but is about 10-30 fish/min (approx. 1-3 t/h depending on fish size). The yield is directly depending on the state of the freshness and consistency of the fish, its fat content and maturity, as well as the cut of the head (I-, C- or V-cut). The simple mechanic solutions based on rigorous geometric principles in combination with a sensitive system to the thickness of each fillet, allow the machine to process fishes of various sizes (from 0.1 to 6.0 kg) without setting changes. The type number means the maximum fish height between anus and dorsum in mm, which the machine can handle. The smart design and sturdy construction (made in stainless steel) insure a long life to meet high conditions and norms of hygiene. All machines work with 2 or 4 blades (and 1 or 2 electric 400 Volt/50 Hz motors), are efficient and easy to clean and maintenance. Each machine has 2 wheels for easy movement. The standard height of the fish inlet is 80 cm and the fillet outlet 77 cm abouve the ground (other dimensions are possible on request). The deheaded and guttet fishes are loaded by hand into the machine. A 10-12 cm high transport belt carefully transfers (approx. 20 m/s) the fish to the round blades knifes which run not parallel but axial. The blades cut the fillets and separate the waste bones, thus saving over 50-75 % of the production time. The filleting machines are available with 2 or 4 blades either for the production of fillets with belly bones (ribs) or for the production of fillets without belly bones (ribs). The water requirement during filleting is about 300-500 l/h. A sharpening tool to use directly on the machine is available as accessory.

The following 2 blade types are available as standard:

All machines are building from non-corrosive material to the quality and work with the same principles. The unique mechanical picking action of theese pinboners gently removes neck and pinbones, leaving fillets looking their best. Pinboning is not only removing the pin bones, but important is also not to break pin bones, not to bleach the fillet by water, and keep the fillet without gaping. They are very user and maintenance friendly and allow fast working. The pinboners are ideal for use by fish processors, fish mongers, fish shops, fish restaurants etc., giving excellent results with best possible yields and minimum weight loss.

ELECTRIC PRESSURE CHAMBER for smoking and grilling

Pressure chamber smokersOur implements are produced by modern machines and they are installed and approved accurately by hand. Due to continuing further development and in close cooperation with the leading professional institutes and associations of fish- and meat industry, as well as due to many suggestions from application in gastronomy, this devices are the most matured smoker, a fact that is confirmed by the best cooks all over the world, as well as by FIMA (marketing institute of the fish industry), by many professional associations as for example VDK (association of cooks) and last but not least by many foreign unions and professional hotel schools.  This smokers with its approved technic are in operation worldwide. It is a product for special gastronomy as smoking is possible at any time in presence of the customer - also in delicatesse-shops, in the groceries store, at the butchers, at the party-service, restaurants, beer-gardens etc.

In the electronic pressure chamber grill and fumigator you can easily prepare hot or cold smoked specialities ready to serve within very short times. You can work with the oven in closed rooms - smoking indoors - always a pleasure. Fish and meat are not cooked directly by firewood or infrared heat, but indirectly by the hot air inside of the pressure chamber. The tightly closing door guarantees that only a very small amount of smoke and thus nearly no moisture are let out. Proper gravy will be preserved, which is a great advantage in comparison to other smoking processes. Fish is put, with its belly up, onto the special grates. Flat-fish, fillet, meat are smoked on the flat grids. Flavour and proper gravy will remain. Cooking without addition of grease, therefore low on calories. Constant temperature and optimal diffusion of smoke (pressure) will lead to a good cooking and a golden-brown colour of the smoked food. After the timer has run off, smoke will deposit on the inside of the walls. The darker they are, the better the taste will be. The special heat-resisting sealing of the doors needs neither maintenance nor renewal. Very low energy costs, over 60% of cooking-terms you can grill and cook without electricity. The double-casing guarantees that no water can enter. All electric parts are protected. Both the interior and exterior of the smokers as well as tin-plates and grates are made of stainless steel. No rusting or loss of colour and enamel. Very short pre-heating times and very low energy consumption due to completely insulated double-casing. Switches and control lamps on the front side a design suitable for modern kitchen. Heating with thermostatic regulation, automatic timer. The standard outfit consist of stainless steel vessel and smoking-pan, 2-4 racks and 2-4 flat grids as well as user maual and recipes.

SMOKING CHAMBERS for excellent product quality

Typ RS-40 + RS-100With this smoker you will get a state-of-the-art and high-quality product finished through CNC-production, containing over 30 years of development and experience. Most remarkable features are simple operation and extremely compact design. With our special integrated smoke-gas-guidance, your smoke goods will get evenly cooked and aromatized. The smoke-gas-guidance takes place over an additional sheet metal in the back to the outlet (see funcion sketch). With this you will get an optimal use of the smoke, the temperature inside the oven is very evenly and the dripping of condensate onto your smoke goods is safely avoided. The aluminium coating offers advantages compared to other coatings as food-proofed and highly corrosion- and heat-resistant. Stainless steel is 100% corrosion-resistant, acid- and leach-resistant, easy to clean thus allow flexible use (smoking of fish, meat, sausages, poultry and savage meat in the same oven possible). This smokers are available in different sizes made of aluminium covered steel or stainless steel with interchangable wood- or gas fiering, for hot- and cold smoking of fishes as well meat and sausages. All smokers come complete with dry-drip-tub and bouncer. Additionall smoking grids, rosts, spits or hokes, smoke pipes (130 mm diameter) also with rain cover are available as accessoire.

Wood firing:
For cold-smoking, the burning box is filled with smoke-flour and the draft regulation is completely closed after lighting. The smoke-flour becomes carbonised and with a maximum fill of the burning box the oven smokes up to 15 hours.
For hot-smoking a fire is kindled in the burning-box. The temperature will be set by the draft regulation. As soon as the smoked goods are dry and cooked, the draft regulation is to be completely closed and the fire is covered with smoke-flour to get a good smoke development. You will get best smoked-results by using pure beech wood. More simple, more comfortable and above all more economically you will smoke your goods with the gas heater.

Gas heater:
Drying and cooking: With full power of the gas heater - without smoke-flour pan.
Smoking: Cutting down of the heater to half power and simply putting the filled smoke-flour pan ontop of it. When the smoke development is completed, the gas heater is switched off and the smoke process is finished.


ISOLATED SMOKING DEVICES made of stainless steelCuring Device

Good and consistent curing results appeal to your customers and widens your customer base best.
This electrically (230/380 Volt) heated smoking devices have a capacity of 20-200 fishes (resp. 15-150 kg meat) per smoking time of 30-90 minutes. Precisely thermostate controlled heating produces heat and smoke for cooking slowly. A smoke pipe connection (120 mm), and the well doubble isolated (50 mm) walls and door prevents heat loss and makes curing possible also in closed rooms. The fish to be cured either be laid on the racks or hung on curing hooks on the racks.
As accessoires a (build in) thermometer, timer swich and a smoke pipe regulator valve, as well as special curring hooks, racks and curring meal (wood chips) are available. On request, a build in connection pipe for/and an external smoke generator (for cold smoking) is available too.

LIQUID SMOKE SYSTEMS for stable product quality

Liquid smoke systems Typ TFSR 80-100This systems are completely different to traditional ones in a way, that they need no smoke generator and burner, because instead of a generator, a tank with liquid smoke will be brough to a pressure of 3-5 bar.
At this patented technology, liquid smoke will be spreaded via an ventilation system over nozzles and recircled during closed ventiles. During this process a steam- and gas phase is build, which generates a non visible smoke. This "smoke" is physically identical with conventional smoke, with all durability- and tast giving substances (carbonyls, acids and phenols) but has no tarphase and other undesired matters (Benzo-a-pyren).
The complete system is microprocessor controlled and allow easily the programming of   temperatures, moisture, times etc. as well as to save up to 99 programs (with 20 steps each). The actual and required parameters as well as alarms etc. are shown on a digital display.
For the full automatic cleaning process (without agressive cleaners or personel) all equipment is placed in the cabinet and the program is started - thats all! Beside smoking, with this cabinets you can also curing, steaming, cooking, backing, roasting etc. all with an allways stable product quality.

Fishes

FRESHWATER FISHES with quality

Arctic Charr (Salvelinus alpinus) and Lake Trout (Salmo trutta lacustris):
The breeders origins from populations of alpine lakes. Suitable for stocking in alpine lakes, reservoirs and dams, as well as for the production of seafood. The fish are raised in
netcages with live zooplankton and therefore are extremely vital and of high stocking value. A high growth rate as well as an excellent meat combined with a nice colour and large sizes are main characteristics. Tests with tagged fish have shown that fingerlings of 3-5 cm is the most economic size for stocking, as the adaptation of much larger fingerlings to the lakes is more difficult.

Grayling (Thymallus thymallus) and Danube Salmon (Hucho hucho):
The breeders are caught in springtime in various rivers, reproduction and raising takes place at the nursery farm on lake "Wallersee" with live zooplankton and later on also with dry food.

Pike (Esox lucius), Pike Perch (Sander lucioperca) and Burbot (Lota lota):
The mother breeders are catched in lakes. Reproduction and raising of fingerlings with live plankton takes place at the nursery farm on lake "Wallersee". Stocking of fingerlings with 3-4 cm is most economic and is more as anought in most waters.

Sturgeons (Acipenseridae):
After years of studies and experiments among most known sturgeon species and hybrids, now from our own broodstock are available -
Siberian Sturgeon (Acipenser baerii): An easy to keep sturgeon which is used mainly for aquaculture and caviar production (available from fertilized eggs to pregraded females).
Russian Sturgeon (Acipenser gueldenstaedtii): A beautifull sturgeon (light scutes on dark ground) which is well accepted as ornamental fish for garden ponds.
Sterlet (Acipenser ruthenus): A slow growing sturgeon which is mainly used for restocking (in the Danube River) but also for the aquarium trade (available also as albino).
Beluga (Huso huso): The "Caviar fish" with the best growth rate, within 2 years a weight of up to 10 kg can be obtained with a water temperature of 20° C.

We produce over 20 fish species during the year like: Chondrostoma nasus, Barbus barbus, Silurus glanis and others.


SPAWNING HORMONES for finfish

In nature, reproductive development and spawning in finfish is controlled by environmental factors such as temperature, photoperiod, nutrition, water quality, and presence of spawning substrate. In aquaculture, it is not always possible or economically feasible to replicate nautral conditions especially as many species are now grown some distance from their original geographic location. Thus, endocrine or a combrination of endocrine and environmental manupulations are utilized to facilitate reproduction. In the last decade significant research has been conducted worldwide on ripening fish sexuality using various preparations.

Carp Pituitary Extract (CPE) are acetone dried pituitaries of carps, which are pulverized and can be used to speed up maturation (induced maturation) as well as the spawning process itself (induced spawning). Intramuscular injections are highly effective in increasing the incidence of spawning as well as possibly increasing egg take in certain species. The potential economic benefits of taking eggs earlier (or later) in a given season or in fact eliminating seasonality altogether in certain climates and regions are significant. Carp pituitary extract contains a variety of pituitary hormones, including gonadotropins, which are effective for the induction of final maturation and ovulation. CPE is administered in distilled water or physiological saline and injected intramusculary at a dose of 1-10 Milligram/kg fish. Available in vials of 1 Gramm (= 1000 Milligram).

Luteinizing-Releasing Hormone analogue (LH-RHa) is another item which current research has brought forth yet as a new approach to induce spawning and maturation. Typically, the hypothalmus portion of a fish's brain is stiulated by complex environmental factors to secrete LH-RH which in turn triggers the pituitary gland to release gonadotropic hormones. The gonadotropic hormones travel by way of the general circulation to the gonads (ovary or testes). The gonadal tissue receiving the stimulus of gonadotropin begins the maturation process whereby the fish is ready to begin reproduction or spawning. A specific analogue of LH-RH is many times stronger than the naturally occurring one. Research has shown this to be the most potent maturation and spawning aid.  Additionally, the LH-RH "a" analogue is not specific to any particular species and should be applicable universally to all species. LH-RH(a) then deals with maturation and spawning at a higher "command level" than do pituitary extracts which are essentially gonadotropic agents. LH-RH(a) is administered in distilled water or physiological saline and injected intramusculary at a dose of 1-100 Microgram/kg fish. Available in vials of 1 Milligram (= 1000 Microgramm).


TRANQUILIZERS for aquatic animals

Eugénol (Clove-oil) is a very usefull, natural and environmental friendly tranquilizer, which can be used for various fish species. A higher tolerance against longer exposure times gives a greater security and makes the application under practice condition much more easier. Because of the low dosage (30-50 ppm) there occures also no alteration of the taste of the fishes. Available as pure oil in vials of 10 or 100 Milliliter.

Tricaine Methanesulfonate (MS-222) is a highly versatile anesthetic intended for the temporary immobilizatin of fish, amphibians and other aquatic cold blooded animals and the most widely used and trusted anesthetic use in aquaculture, fishery and veterinary settings. It has long been recognized as a valuable handling tool during surgical operation, stripping, weighing, measuring, tagging, transportation, photography etc. Tricaines are not affected by salinity. Fish anethetised show rapid reversibility when placed in fresh water. Further, the level of sedation is proportional to the strength of anesthetizing baths. It is available as a white, water soluble powder available in bottles of 100 or 1000 grams administered by bath, used for anesthesia and sedation at a dose of 20-200 ppm, with an induction time of 2-20 minutes.


DISINFECTANTS for aquaria and aquaculture

We supply various chemicals for desinfection in aquaculture and aquaria. Some chemicals are in some countries only allowed for fish which are not used for human consumption, like eggs, spawners or ornamental fish.
The following chemicals are available:

Actomar for desinfection of equipment, fish and eggs;
Chloramin against gill diseases and Myxobacteria;
Copper sulfate against gill diseases and algae;
Virkon against bacterioses and viroses;


CONSULTING for aquaculture and fishery

An european-wide 25 years' experience and know how in the field of aquaculture, longtime cooperations with important scientific instituts and researchers, worldwide contacts and the experience-exchange on numerous international congresses and symposiums are the base of our respectable and successfull consulting in management of waters and fish stocks, and in planning and construction of production systems, not only for freshwater but also for brackish- and seawater.
In cooperation, our team can offer:
