MODULAR FLOATING DOCK SYSTEM for aquatic sports and aqua culture

Maritime Technic - Pontoon System25 years experience in "state of the art" flotation 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 utilizing the friction co-efficient achieved by independently controlled flooding of the 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 individual modules are easy to handle (weight: 6.2 kg) and have a very high load capacity of 360 kg/m2 (=75 lbs/sq ft). They are made of a high-quality synthetic, UV-stabilized and anti-static material (green or blue), which is extremely resistant to the elements. Individual blocks measure 50x50x50 cm (1.65x1.65x1.65 ft) and the standard freeboard is approximately 40 cm. Blocks are easily assembled (with an assembling wrench) by joining the connecting lugs with bolts that give a secure and stable connection.
These building blocks can be assembled to meet any desired layout or dimensions, 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 utilized throughout the year or the modules can be stacked and stored. Unlike closed floats, this system does not blow up in the sun and is resistant to attacks from Teredinidae.
Unlike conventional wooden floats, the pontoons are made of a skid-proof material, and will not rot or develop sharp edges, or expose rusty nails etc. The "Maritime Technic - Pontoon System" contributes to water purity and is aesthetically pleasing. It has lugs (ears) along the sides where different accessories can be fitted and anchoring systems attached.
Swimming ladders safety rails, anchor fastening and and boat -mooring-eyes are the main accessories, with options such as side screws and bars as well as fenders, ropes and anchors. If needed, access ramps and gangways can be produced to the customer’s design. For marinas electricity distributors (w/wo illumination) and water supply-systems are available.

ILLUMINATED NET CAGES for the fingerling production with natural zooplankton

Illuminated submerged cagesystem20 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 center 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. The 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 aluminum 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 faces, 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.



UNDERWATER LAMPS to increase growth and delay maturity

LED underwater lampThis new underwater lamps with LED (Light Emitting Diode) are especially energy saving and have a long service life (approx. 30,000 hours). They are used successfully in both fresh- and seawater, either in the night to attract various aquatic organisms (like zooplankton or squid), or during the winter for the simulation of daylight (24 h/day) to delay maturation and increase growth (up to 10-30 %) in several fish species (like Salmon or Cod etc.). The professional lamps are available with different light colors: blue (approx. 40 lm/W), yellow (approx. 60 lm/W), green (approx. 80 lm/W), or white (approx. 100 lm/W = Lumens/Watt), whereby optimal to attract zooplankton (copepods, phyllopods) is blue light (around 450 nm), to attract squid, shrimp and fish in seawater is green light (around 500 nm), and to attract fish in freshwater is yellow light (around 600 nm). To simulate daylight, mainly blue or white light is used, whereby blue light penetrates furthest in water but white light comes closest to the natural light spectrum and can be used for all or general purposes. The recommended power in white LED light (4,000-6,000 Kelvin) is about 1-3 Watt/m2 of the holding unit (tank or cage). The self-sinking and water-proof (IP68) lamps can be used for a water depth up to 10 m (1 bar) and a water temperature up to 30 °C. They are made from high quality plastic and stainless steel (AISI316), with LED's (SMD 3528) placed on 4 sides for a 360 degree lighting angle, which reaches up to 5 m (depending on water turbidity). This submersible lamps are delivered complete with a fixed cable (5 m) and are available for 12 V/DC with two crocodile clips (the 4 larger models are optionally also available for 220 V/AC with a transformer).

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 fulfills all requirements of today's aquaculture and hydrological needs. Appropriate sieve fabrics are offered per running meter and as standard or customized products, such as filter-, dip-, hatching-, cage- and plankton-nets.
In Austria a catch of zooplankton for the production of fry and fingerlings is commonly practiced since more than 50 years. During the last years several important optimizations are archived allowing a better net construction and easy catching. With appropriate designed plankton nets, harvests of several tons per day can be achieved. Thanks' to this Austrian development of special sieve-net-systems, it is possible to grad the plankton in 3 different size classes during the catch. The result is the correct plankton 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.

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 petrol motor was not over motorized for the boat and the use.
All models have a compensated row motor, which coiling compensation optimizes the energy usage and increase the output of the motor, specially at higher turns. The casings as well as all supports are made from marine aluminum (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 shaft 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 pin, 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 accessories.
Additionally, special batteries for long time use with high cycle stability, battery loaders, and (from 36 V on) a steeples motor regulation is available.

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 fish pools 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. Aquaponic kits or hydroponic sets are available optionally.

Recirculation System

RECIRCULATION SYSTEMS for the intensive production

The modules for production are available for a yearly production-capacity of min  25 t/year (standing crop 10 t) onward and allow our customers to get familiar with the technique and topic without high risks. The water from the fish pools 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 fish tanks, witch could be adapted to customer wishes in form, size and number. The use of UV- or ozone is possible too. This system is available for all fish species (also salmonids).

FILTER CHAMBERS with swirl separator

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 trapped 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 glass, Aqua rock, Bio balls, Poly foam etc.). The waste particles concentrate at each cone, where they can be removed regularly 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 sucked 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 systems. A regulating system allows to operate the skimmer also under extreme differing situations of water column. Each skimmer, made from acryl and/or polypropylene (on request also from polyethylene), could be also used as ozone reactor. The optimal retention time is about 2 min., if the flow rate is increased the retention time decrease.

BIOFILTER MEDIA with high settlement area

Biofilter Material

For Recirculating Aquaculture Systems (RAS) as well as aquaria and ponds or for the biological cleaning of waste waters after fish farms or culture ponds we supply the carrier or settling material for the biofilter which can be used in fixed or moving bead filters. The filter media are made from HD-PE (density 0,94-0,96 g/cm3) and is available of recycled raw material (black) or virgin raw material (white). They have a large settlement area for bacteria and allow a good biological cleaning from ammonia to nitrate (nitrification) as well as from nitrate to nitrogen (denitrification). The nitrification rate is approx. 0.5 g NH4-N/m2 in moving bead or flow filters (in fresh water at a water temperature of over 20 °C). In fixed bead or sprinkling filters, with a reduced cleaning capacity respective with more filter material of 20-30 % must be calculated. In seawater, as well as at water temperatures under 15 °C, with a reduced cleaning capacity respectively with more filter material of 40-60 % must be calculated. Other random media (like: chips/flakes/saddles) with up to 5,000 m2/m3, on request.

WATER DESINFECTION with UV-light

Ultraviolet light (UV) destroys microorganisms (like: virus, bacteria, fungus, parasites, algae, etc.) by changing their genetic information (DNA), but does not produce residual or hazardous by-products, nor does it affect the taste, odor or color 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 disinfection is UV-C (200-280 nm), specially with a wavelength of 254 nm.
UV-C Inline system (with control box)The heart of the UV systems are high-performance lamps (low pressure technology) which provide a stable UV output through a wider temperature range (1-45 °C). This special 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 (9,000 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 up to 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.
By studying various reactor geometries with respect to the UV intensity distribution and hydraulic characteristics (0.5-6.0 bar), specific reactors types in stainless steel (AISI 316 or V4A) with 1-16 lamps where developed to provide effective disinfection while minimizing 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 disinfection for up to several m3/h. This systems are characterized by their high disinfection performance, combined with compact construction and low energy consumption (220-240 V/50-60 Hz).

ULTRASOUND DECVICE to destroy algae and protozoa

Ultrasound algae destroyerAlgae are problematic in many water areas and can create huge problems and high costs in industry, agriculture and other fields where water is used. Algae also make ponds and pools to ugly holes and can settle on boat hulls - where expensive antifouling coatings are necessary. This digital ultrasound devices (100-250 V/50-60 Hz AC or 12-24 V/1,5-2,0 A DC) send to the water (pond, pool or lake) special ultrasonic sound waves in periodic time scales trough the transducer in an angel of 180° on the front side. The wave length is depending on the type of the device and the mentioned distances are based on average values which can vary according to local circumstances, like water quality and water plants etc. In every algae the is a microscopic liquid bubble called vacuole. Our digital ultrasound device force that to swing which burst and finally kill the algae. But this is specific to different algae species. Single cell algae are killed after a treatment of 7-10 days, but filamentous algae need a longer treatment and die after 3-7 weeks. In which time the water will get clear depends also on the biological balance in the water. But also the quality and capacity of the eventually installed filter plays an important role. Additionally, with the ultrasound also the biological film (which builds up as sludge on the bottom or wall) in your water will be reduced and remove the base for many diseases pathogens like fungi or bacteria etc. The created ultrasound are not to hear for humans. If the device is in operation you may hear just a little ticking. But some other animals like dogs can hear it and may stay away from the device. Other is the whole with fishes, which some customers report prefer the ultrasound and stay nearby may because their skin is cleaned from parasites. Fishes feel not only better but also grow faster and are healthier with the ultrasound device.

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 (0.75-1.50 kw (1.0-2.0 HP) 230 or 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 faces 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) trout 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. These proven aerators are supplied complete with motor, supports, float kit and propeller protection fingers. They are lightweight compact systems ( 21 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 maximizing efficiency). In enriching the water with air or pure oxygen, this aerator can create good circulation with a lesser amount 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.

PADDLEWHEEL AERATORS for intensive production

Paddlewheel Aerator with H-floatThis paddlewheel aerators widely used all over the world, special in intensive ponds and raceways. They are available with 2-6 paddle wheels, in different power ratings from 0,75 to 2,20 kw (for 220 or 380 Volt) and have a weight of 80-120 kg. The oxygen introduction is up to 1.5 kg/kwh or with 6 mg/l at beginning approx. 0.5 kg/kwh. Wheel and frame are made of steel, the paddles from special plastic material and the H-formed floats from thick UV- and ozone resistant plastic.


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 efficiency, 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 efficiency and also reduce the possible parts which could become defect with time. A very long self live and high efficiency is also guaranteed through the worm-gearing. The motor is specially sealed against 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 Aerator with T-floatOxygen cover

To use this paddlewheel aerators also with pure oxygen instead of air, as accessories 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 % and the oxygen introduction up to 2-3 kg O2/h.


RUBBER DIFFUSER with stainless steel frame

Rubber Diffuser in stainless steel frameThis professional, 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 always ready to operate. An uniform bubble size due to the straight hose mounting in a stainless steel frame are main features of this professional diffusers. The sturdy hose connection is 6 mm as standard (and is also available in 9 mm if preferred).

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 saturation 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 air

Cross-Diffuser (floating)The fine pored ceramic tubes allow to diffuse the air in fine bubbles. The diffusers should be installed in the same depth, 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 feeding 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. 1.5 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 largely 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 waste 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 tubular membrane and solid air diffusers, but with few of the disadvantages. Solid diffusers can break or become blocked by biofouling, iron and carbonate precipitation. Membrane and other tubular diffusers 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 3 m in length, and with extension parts also longer) 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 approx. 200 mbar (<3 psi). All diffusers are supplied with 1/4-1/2" hose tails.


MEMBRANE COMPRESSORS for Direct Current

Membrane CompressorThis simple 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 accessories 6 mm hoses and various diffusers are available.

SIDE-CHANNEL BLOWERS for water aeration or delivery

Blower Type VThe design of these blowers is based on long experience in blower production. The motor (standard 380 Volt/50 Hz, 2850 RPM) is made for endurance and is offered in different power sizes. The flow capacity based on air at 981 mbar and 20 °C (at the inlet connection) ranges from 110-300 m3/h. Because of the small dimensions and compact construction, as well as the low noise level (45-48 dB), these blowers can be placed almost anywhere. The blowers can be installed singly, in parallel, or in rows for an increase in pressure. On request the blowers can be produced for us in seawater, or for other voltages and frequencies. Air filters, pressure valves and support stands are available as accessories.

The typical emerged blowers (type V) are installed only on the land, but at almost any location. An advantage in recirculation systems is that the heat in the air of a room can be used to heat the water.
The special submerged blowers (type T) are installed directly in the water and therefore allow shorter piping, as well as lower pressure losses. They are much quieter and also save space. An additional advantage in recirculation systems is that the heat generated by the blower motor will heat water.


REGENERATIVE BLOWERS for pressure or vacuum generation

Regenerative Sidechannel Blower (doubble stage)This reliable and favorable blowers summaries modern know-how of pressure and vacuum generation, based on longtime experiences. The motor is 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 regenerative. 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. The machines are delivered as mono stage (M) or double stage (D) blowers with single (S) or twin (T) impeller. As accessories air filters, sound absorbers and security valves are available.

OXYGEN GENERATOR SYSTEMS for intensive aquaculture

Oxygen GeneratorIn recent years, fish farming has turned into high density farming practice and pure oxygen is essential in modern aquaculture. Several studies have shown adding dissolved oxygen into water on fish farms has a very positive effect on growth rates, feed conversion and mortality rates, all factors that will affect the profitability significantly. On-site oxygen generators allow an uninterrupted supply of gas with a high purity output (adjustable 85-95 %, outlet pressure 4 bar). This means that you can produce gas where and when you need it, and in the exact quantity and quality you need, to reach gas self-sufficiency and independence from external gas suppliers.  This oxygen generators are known as reliable, easy to use and low operational cost. They save energy and money as supply of oxygen cylinders or rent of liquid oxygen tanks becomes irrelevant. The average oxygen production cost are about 1,1 kwh per cubic meter of oxygen. An oxygen generator combined with cylinder gives the highest level of backup in comparison with cylinders it gives overall cost reduction up to 80 %. We use only high quality components and all systems are designed for 24 hours, 365 days a year’s operation. They are easy to operate and require minimum amount of maintenance and service.
This proved generators are based on the well-known PSA (Pressure Swing Adsorption) technology, using two pressurized columns with molecular sieves to ensure continuous production. Dry compressed air is blown through a valve to the vessel where the pressure is built to reach 5 to 7 bar(g). Oxygen is tied to a molecular sieve during the building of pressure and the nitrogen is allowed to pass through to the accumulation tank. While pressure is built in vessel, the second remains without pressure. A part of the produced gas is used for regeneration of the molecular sieve, which, in the case of Nitrogen, is a Carbon Molecular Sieve (CMS). The entire PSA system can be subdivided into several components like: air compressor, air dryer, air tank, oxygen generator, oxygen tank and accessories. The models are available with a capacity in the range from under 1 to over 400 m3/hour (at an oxygen purity of 90 %). Oxygen cylinder filling stations are available on request.

SATUROMETER to identify gas super-saturation

SaturometerThis new handheld saturometer (Protection class IP65, with electric backlight display identifies gas super-saturation in water reliably to 250 hPa resp. mbar pressure difference (displayed also as % total gas saturation), with an accuracy of 1 hPa. It works with a usual 6 x 1.5 Lithium cells, with integrated capacity monitoring on the meter. The maintenance free sensor is completely sealed (Protection class IP67, Signal outlet 0-5 V). As option also oxygen (O2) and/or carbondioxyd (CO2) sensors can be connected to the meter, and with the optional software it than even calculates  nitrogen (N2).
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 super-saturation has a significant negative impact on the fish immune system. A fish stock infected with IPN (Infectious Pancreas Necrosis) produced losses of 10-15 % after 90 days whereas fish from the same stock exposed to super-saturation showed a mortality rate of 65 %. The gas bubbles themselves cause a lot of direct damages like lesions and embolism. 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


OPTICAL DISSOLVED OXYGEN SENSOR to connect on systems or computers

Optical Oxygen SensorThis new development is the first optical oxygen sensor with SCS interface (Simulation Clark-Sensor), for a perfect integration into running systems. The ideal substitute for your existing oxygen sensors. Via the SCS interface downward compatible to classic oxygen sensors (galvanic isolation), works together with classic transmitters. Additionally, the sensor can be connected via the 4 to 20 mA current output or with a process control system (SPS). As accessories, a PC-adapter (USB-RS485) is available, with which the sensor can be connected directly to a personal computer, and configures from there (Software for free), where just a net-device is needed and no external meter. The calibration is simple and only needed once as the calibration data can be stored in the sensor. The robust and simply exchangeable sensor cap has a warranty of 2 years. It guarantees stable values at once, little drift, quick reaction time, and all independent from incoming flow. The sensor has no sensitivity towards H2S or CO2, but an automatic temperature compensation and malfunction diagnosis. Measurement range 0-20 mg/l, 0-200 % sat., resolution (at 25 °C) +/- 1 %, limit 0.1 %, reaction time < 60 s, temperature range -5 to +50 °C. The sensor can be delivered with an IP68 termination plug or with a fixed cable in different lengths. For mounting in a probe holder the sensor can be delivered optionally with a 1" process connector. For fish farming there is a robust version with a biting-protection with nut inserts available for water depth up to 20 m. A display- and regulation system (for up to 8 sensors) is available as accessories.


MODULAR MULTIPARAMETER measurement and control system

Modular Multiparameter Process ControlWhen it comes to automatically controlling and adjusting critical water parameters, it leaves nothing to be desired. Due to its flexible modular concept, the system is the perfect solution for most applications in aquatic environments. Apart from comprehensive timing functions, it provides measuring modules for the parameters of pH value, redox potential, temperature, conductivity, level (fill level), oxygen and air pressure.

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 uniformly 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 preferred water flow so that the eggs at the base are rotated uniformly 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 accessories) 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 swim out at just the right time. Now you can virtually duplicate nature's way of hatching eggs with this durable, see-through incubator jar. So next time you want your eggs "over easy", make sure you are using this hatching jar.


INCUBATION JAR SYSTEMS with overflow

Weiss Jar SystemThis simple and cheap jar system is suitable for hatching of eggs of various fish species, like carp, pike, perch, catfish, burbot, sturgeon etc. It is made of stainless steel frame and saves space and water. Each "Weiss or Zougg" jar made of glass with a volume of about 9 liters and bottom sieve, has a its own inlet pipe with valve and a overflow with pipe, so that it can be supplied individually with water. After hatching the larvae usually leave the jars by themself with the water flow or are removed by the farmer from the jar. The system can be build with any number of jars (up to 10 pieces in single and up to 20 pieces in double row).


BREEDING JAR SYSTEM with top tank

Zougg Jar SystemThis well designed systems are made of stainless steel and are equipped with "zougg or weiss" glass jars witch can be removed and serviced separately. Through the inlet tank on top, all jars can be individually supplied with water. The tank and feet are somewhat adjustable in height. The eggs of various fish species (Cyprinids, Esocids, Thymallids, Coregonids etc.) are incubated in the jars and rotated gently by the water flow. A breeding cone for salmonid eggs and an overflow sieve (1-2 mm holes) to avoid eggs or larvae being spilled out by water, is available as accessories. The standard systems have dimensions (LxWxH) of 115-215x40x165-185 cm and are equipped with 3-7 glass jars each with a volume of 8 liters. Other sizes or 3 liter jars are possible on request.

The water (min. 5 l/min) from the inlet, flow trough the trays on which the eggs stay, 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 water. Without disturbing the other trays, each tray (approx. 62x52x8 cm) can be drawn out and controlled easily and provides in the inserts (approx. 45x37x5 cm) perfect conditions from the fertilized egg to the swim-up stage. They are available with 5, 8, 10 and stacked with 16 or 20 trays for up to 1 liter or 10,000 eggs per tray) made from strong non toxic plastic material and includes the aluminum or stainless steel frames (approx. 64 cm deep, 58-60 cm wide and approx. 50, 84, 100 and 175 or 210 cm high, changes reserved) and all egg trays with polyester screens (approx. 1-2 mm).


VERTICAL INCUBATORS to save water

Vertical Incubator with top tank and support frameThis vertical incubator allows optimal conditions for the incubation and hatching of salmonid eggs (like: trout, charr, grayling etc.) and save water. The water (only 1.8 l/min) from the top tank with float switch and filter tube flows by gravity trough the trays, from the central inlet funnel through the sieve baskets where the eggs stay, and leaves the tray via the outlet holes all around the sides, where if lows down the cone shaped tray to the next one a.s.o., so that all trays will be supplied with sufficient oxygen. Without disturbing the other trays, each tray can be drawn out and controlled easily and provides optimal conditions from the fertilized egg to the swim-up stage. The corpus made of black plastic has a removable and roll-up front cover also made of plastic material, which reduces light within the incubator. The incubator is available with 10 trays and baskets (for 100.000 eggs respectively up to 1 liter eggs per tray) made from aluminum (approx. 40 cm diameter and 5 cm high). The whole incubator has dimensions (W x D x H) of 48 x 62 x 128 cm. A support frame (45 cm high) made of stainless steel is available as accessories.

The screen (1-2 mm holes) of the egg incubation baskets are fitting exactly. The water (min. 0.1 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. Optional an outlet screen is available. This troughs can also be used for start-feeding of the fry after the yolk sac has been absorbed.


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 (like salmon and trout, as well other species on request) in natural streams. The flood save and closeable box is made of stainless steel with dimensions of (LxWxH) 90 x 20 x 13 cm, weight approx. 13 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 control (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 themselves in the brook or river.


HATCHING SUBSTRATE for stronger fry

Hatching substrateMainly 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 usually practiced. 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 naturally occurring 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.


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. A water and compressed air supply is needed for operation.
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.

This graders are made of aluminum and stainless steel and are available for various fresh- and sea- water fishes from Salmoniformes and Cypriniformes to Perciformes etc. The grading technology is based on 2-5 V-shaped channel with moving plastic fingers below, which moves the fish until the channel is too wide for the fish thickness and the fish are released to the collecting tanks below, from where they are flushed with water to the outlets, and additionally by pipes back to the holding ponds. During the whole grading process the fish are kept wet by water (submersible pump as option). The machines are mounted on a trolley with 2-3 wheels. Equipped with 380 V/50 Hz motor (230 V on request).

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 (0,2-50,0 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 separate 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 chargeable 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 accessories kits are available to count fry from 0,2-0,5 g.

FISH COUNTERS for graders or pipes

Fish CounterThis newly developed fish counter series made of aluminum and plastic was specially developed to count fast (about 4 t/h) and accurately (over 98 %) live fish like salmonids, cyprinids and percids (from 5-5000 g) after an automatic grader. The counter is simply connected to the outlet tube of the grader or any other tube.. Provided with programmed intelligence, the fish counter performs various controls (auto-test) and informs the user in case of failure. The electronic display provides the following information: number of fish counted, status and degree of sensivity selected. The two new sensors with transmitter and receiver modules are mounted into a slide and are provided with an electrical connector. The graphic display and the power supply cable are also equipped with an electrical connector (Input 90-220 VAC/15 VDC). The various connectors are connected in the junction box of the main module. All electronic parts are sealed, easily removable and replaceable by the user. The counters are available for fresh- or seawater use and supplied with a set of separators and two support legs. A reception tank/funnel with 160/200 mm diameter pipe connection is available as accessories.

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 splash-proof 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 aluminum case which is sturdy, splash-proof 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 accessories). 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 auxiliary 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 powerful electric fishing devices are successfully 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 preferred. The electric building corresponds to security class II. Therefore all power delivering parts are double 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 arise. The permanent excited generator and the high quality magnet materials guarantee a continuous and reliable power. Each device will be tested mechanically and electrically completely and delivered with user manual.
Direct current creates usually a better anodic reaction as impulse current would doe. But at extreme conductivities or for electric barriers with direct current soon the borders are reached. As result, powerful combined (Direct-/Impulse-Current) devices where created, where the impulse frequency and volts can be adjusted (via motor turns or switch). The back-carry units are compact lightweight systems with high outgoing power. Impulse devices are a little larger and have a little more weight than direct current devices.
We deliver net-, battery- or petrol-driven back-carry- or stand-devices with direct- and/or impulse current with an outgoing power of 250-11.000 Watt (5-160 kw/impulse 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 accessories are available: 30-50 cm Ø Stainlesssteel-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 DEVICES with or without cleaner

Gutting device-stand set (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 gut and clean fish (like trout) from 150-1000 g (optionally up to 2000 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.
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 knife comes down and cuts the gorge, which is than sucked and stored in a container. Optionally, after gutting the remaining blood is removed by the rotating (1500 RPM, 20 cm diameter) round washing brush. The rational working sequences enables one person to process 300-400 fish per hour.
The new reworked and improved version (wall- and stand models) have a gutting head which can be removed without tools and is dismantled in seconds, which allows good cleaning and disinfection. The  removable suction head fits to usual 120 l waste containers, which allows easy and fast replacing and deposition. These stainless steel gutting devices are delivered complete as table, wall or stand units with or without compressor and vacuum cleaner and with or without round rinsing brush.


AUTOMATIC GUTTING MACHINE for round fish

Fish gutting machineThis robust fish processing machine (for fishes (like trout, charr, bass, mackerel and herring) is made from stainless steel. A main point at development was the removement of complicated and failing technique. The compact machine (LxWxH 2,6x0,6x1,9 m, weight 350 kg) is nearly maintenance free. Complicated and expensive engagements are not necessary and the function via a button allows for rentable gutting (removement of intestines and gills). The running speed of the machine is adjustable, to allow to feed the machine with the fish up to 3000 pc./h with a weight between 150 and 1200 g (max. adapted to the double size difference e.g. 300-600 g). The water demand is about 500 l/h, air pressure min. 6 bar, electricity 1,2 kw/h 380 V/50 Hz (others on request). As accessories a feeding tank (before the machine) and a control sunk (after the machine) is available.

MANUAL SCALING DEVICE for all fishes

Manual scaling deviceThis fish scaling device is well protected from spray water, safe in operation and securely insulated, tested to 4000 V. The 230 V/50 Hz ICE standard 0,1 kw motor can be used continuously. The machine LxWxH of 23 x 24 x 19 cm with a weight of 9 kg, can be connected to a grounded or non-grounded wall socket. The cover of the laminated, flexible axle (160 cm long) consists of two layers of steel, one layer of insulating compound and one layer of plastic. The ball bearings in the top, with which the fish is scaled, are waterproof and all outside parts are rustproof. The device is supplied completely with handle, feet, 160 cm cable and plug.
As accessories 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 fish 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 fishes

Fileting machineThis 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 height output (approx. 100-200 kg/h) and safety measurements allow a fast working. The compact design (LxWxH: 118 x 56 x 127 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 skin can also be removed manually or by skinning machines. A continuous cleaning is done by water spray nozzles. As accessories an (20-40 degree) adjustable forwarding belt (30 cm/s, wide 35 cm, length 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 above the ground (other dimensions are possible on request). The beheaded and gutted 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:

BONE CUTTERS for fish filets

Y-bone cutterWith this compact manual devices made from stainless steel, you can cut (Cutting wide 9, 15 or 30 cm) fast and easy the Y-bones in fillets from bony rich fishes (like cyprinids, etc.). With this cutting in small distances (every 3-4 mm), the numerous Y-bones are chopped in very small pieces, so that they are no longer detected or dangerous in the fillets and can be eaten comfortably with the meat.
With a special adapter (available as accessories) you can also cut now the fillets in chips or stripes (and, for example serve it fried or on salad).
There is also a stripe or cube cutter available (i.e. for herring or salmon) which saves about 50 % of working time. The cutting distance can be chosen in steps of 4 mm, i.e. 8, 12, 16, 20 mm (please mention at order).

On request also an electric bone cutter is available.


PINBONE REMOVERS for fish filets

Automatic PinbonerFor removing of small and unwanted pin-bones from larger fresh, de-frosted or smoked filets (from about 150 g filet weight on, like: Salmons, Trout and Chars) different pinboners, from compact handheld devices to automatic band machines, are available. All machines (motor: 220-240 V, 50-60 Hz) are building from non-corrosive material to the quality and work with the same principles. The deboning unit can je adjusted in height, angel and speed. The belt can also be adjusted in speed. During operation, the machine units are kept clean with water or air. The unique mechanical picking action of these pinboners gently removes neck- and pin-bones (90-95 % at single- and 95-100 % at twin-systems), 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. Optionally all machines are available as twin models (with 2 heads after each other). As accessories also a vacuum system is available which sucks away the bones and water from the fillets.

It is a product for special gastronomy as smoking is possible at any time in presence of the customer - also in delicatessen-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 specialties 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. Flavor 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 color 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 color and enamel. Very short pre-heating times and very low energy consumption due to completely insulated double-casing. Heating with thermostatic regulation, automatic timer. Switches and control lamps on the front side a design suitable for modern kitchen. A new version (HS-36) in Gastro-Norm (GN) is also available.

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 carbonized 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 on top of it. When the smoke development is completed, the gas heater is switched off and the smoke process is finished.

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 brought to a pressure of 3-5 bar.
At this patented technology, liquid smoke will be spreaded via an ventilation system over nozzles and recycled during closed vents. 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 taste 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 aggressive cleaners or personnel) all equipment is placed in the cabinet and the program is started - that's all!

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 color 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 in tanks 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 in tanks with live zooplankton. Stocking of fingerlings with 3-4 cm is most economic and is more as enough 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 beautiful sturgeon (light scutes on dark ground) which is well accepted as ornamental fish for garden ponds.
Ship Sturgeon (Acipenser nudiventris): A rare and interesting sturgeon which builds also freshwater resident populations (in the Ural and Danube rivers).
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 AGENTS 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 natural conditions especially as many species are now grown some distance from their original geographic location. Thus, endocrine or a combination of endocrine and environmental manipulations 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 intramuscularly at a dose of 1-10 Milligram/kg fish. Available in vials of 1 Gramm (= 1000 Milligram).


TRANQUILIZERS for aquatic animals

Eugénol (Clove-oil) is a very useful, 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 occurs also no alteration of the taste of the fishes. Available as pure oil in vials of 10 or 100 Milliliter.


DISINFECTANTS for aquaria and aquaculture

We supply various chemicals for disinfection 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 disinfection of equipment, fish and eggs;
Chloramine against gill diseases and Myxobacteria;
Copper sulfate against gill diseases and algae;
Virkon against bacterioses and viroses;


STARTERBACTERIA for ponds and recirculation systems

For the startup and stabilization of biological filters in recirculation systems, but also for biological cleaning of water in culture or garden ponds, special bacteria sets have been developed. The highly active bacteria also help to stabilize existing or old filter systems. Available as liquid product in containers of 5 l or as dry product in containers of 400 g, each reaching for up to 50 m3.


CONSULTING for aquaculture and fishery

An European-wide 25 years' experience and know how in the field of aquaculture, longtime cooperation with important scientific institutes and researchers, worldwide contacts and the experience-exchange on numerous international congresses and symposiums are the base of our respectable and successful 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:

Natural waters:
Consulting in questions of water-management, composition of ecologic rational stocking-plans. Accompany (also scientifically) on restocking-projects for Sturgeons, Salmons, Trout, Pearlmussels a.s.o. Realizing of water-investigations and fishstock-examinations. Settlement of fishing-actions with electricity, seine- and gillnets in lakes and rivers. Planktoncatch- and stockanalysis for lakes, ponds, lagoons and fjords etc.
Management of fish-stocks in fresh- and seawater. Solutions for parasite-problems, slow growing fish-stocks or to low catch-quotes. Suggestions for high catch-compulsion. Breeder-catch, re-production and reward rearing of autochthone and sensible fish species and forms (with zooplankton).

Production systems:
Planning of farming and production systems for freshwater and marine fishes as well as shrimp. Calculation and preparation of economy- and feasibility-studies as well as water- and market analysis and project reports and funding proposals. Engineering in the field of aquaculture and marine. Construction of hatchery-, nursery-, netcage-, recirculation- and docking-systems. Management and marketing for fish production plants. Education and mediation of professional personnel for aquaculture and fishery.
We also developed a new economy-business plan model, based on a table calculation program (like MS Works, Excel or Lotus). You can enter all variables like: feeding rates an conversion factors, survival and selling rates, stocking density and tank sizes, prices etc. and it will calculate approximately forecast growth and stocks, investment and operation costs and all other requirements.

Get in touch opportunely is important for rational planning and success!


PUBLICATIONS about fish and farming

The Sturgeons and Paddlefishes (Acipenseriformes) of the World: Biology and Aquaculture.
By Martin Hochleithner and Jörn Gessner.
An extended, updated and reviewed third edition. Soft- or Hardcover, 248 pages.

The breeding and culture of sturgeons in captivity has advanced rapidly over the past several years. With recent developments, the requirements of the industry have changed, and the techniques used have also evolved and been adapted to meet these changing needs. Based on experience gained in the the former USSR, new technologies have been developed, and the background of sturgeon biology has been enlightened in many respects. This compendium is designed to close the information gap between scientists and practitioners. Its appeal will be far reaching since biologists, field technicians, hatchery operators and fish farmers, fisherman and fish enthusiasts, will all find a wealth of practical information relevant to their field of interest. The book has the style of a species synopsis coupled with everything anyone needs to know about the reproduction and culture of acipenserid fishes. It summarizes current knowledge on all sturgeon and paddlefish species worldwide and presents it as a practitioner-oriented working guide. It draws on the experience and research findings of the authors gained over more than two decades. The new, third edition has been updated, extended, and reviewed, and includes many new color illustrations. It value will be timeless.

Sturgeon Fishes (Acipenseriformes): Science as Art.
By Paul Vecsei and Martin Hochleithner.
Hardcover, 120 pages.

Sturgeon illustrator Paul Vecsei and sturgeon farmer Martin Hochleithner are both internationally well known specialists in the field of sturgeon research and aquaculture. In this volume, they showcase the numerous sturgeon species and highlight the plasticity of sturgeon morphology (both within and between species) using more than 130 detailed illustrations and many summary tables. The material in this book is the culmination of 5000 hours of scientific illustrations. Each illustration is of an individual fish and is extremely accurate. They are made in the technique of pointillism, a known fine-art technique. Each picture is made by small dots, which, when viewed for a distance, creates a very detailed rendition of shape and form. Sturgeon aficionados, sturgeon experts and art lovers will appreciate the collection of illustrations in this unique work.

The Bibliography of Acipenseriformes: With over 10000 References.
By Martin Hochleithner, Jörn Gessner and Sergej Podushka.
Available as searchable electronic version (on CD-ROM) or printed book version (over 500 pages).

This bibliography, which includes nearly all publications from around the world, and covers all Acipenseriforms and a range of topics, is intended to serve as a ready reference for researchers, fisheries managers, aquaculturists and conservationists who work with this ancient fish group. The numerous references are listed alphabetically by author(s) and chronologically by year(s), as the original title. Almost all sturgeon- and paddlefish species are threatened or endangered. Information on them is by no means complete, whether in fields related to sturgeon culture, biology, ecology or management. Due to the current rate of wild-stock exploitation and environmental degradation, the availability of new information might prove crucial for their survival. This is an attempt to disseminate information about work carried out to date, and to increase its availability.

The Bibliography of Acipenseriformes: Update of the 2000's.
By Martin Hochleithner, Jörn Gessner, Sergej Podushka, Mohammad Pourkazemi and Qiwei Wei.
An update for the years 2000-2009. Paperback, 280 pages.

This bibliography, which covers all Acipenseriforms and a range of topics, is intended to serve as a ready reference for researchers, fisheries managers, aquaculturists and conservationists who work with this ancient fish group. Almost all sturgeon- and paddlefish species are threatened or endangered. Information on them in any field is by no means complete, whether related to sturgeon culture, biology, ecology or management. In many aspects sturgeon biology is very different from that of other fishes, and techniques suitable for other species may not work with them. Due to the current rate of wild-stock exploitation, the availability of new information might prove crucial for their survival. This is an attempt to disseminate information about work carried out to date, and to increase its availability. This is the most important and comprehensive bibliography about Acipenseriformes, and includes nearly all publications from around the world. The references are listed alphabetically by author(s) and chronologically by year(s). This update includes the years 2000-2009. This update is already included in the bibliography on CD-ROM.
