VERTICAL INCUBATORS for salmonid eggs
This vertical incubator 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/s) 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
The 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.
BREEDING BOXES for running waters
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 fry
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.
HATCHING JARS made from plastic
Used successfully for over 20 years by
federal, state and professional hatcheries and fish producers here and abroad, this
McDonald type hatching jar become the standard of the fish farming industry. It can be
used for a wide variety of species like: Salmonids, Thymallids, Coregonids, Acipenserids,
Percids, Cyprinids etc. Made of clear, high impact, 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 (1.1 kg). A
circular filter/mesh screen prevents 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 SYSTEM made from stainless steel
This systems are made of stainless steel
and are equiped with glass ars wich can be removed and supplied seperatly. Through the
inlet tank, all jars can be individually supplied with water.
The standart system has 3-7 Jars each with a volume of
8 liters, other sizes or jars are also possible, depending on customer design.
Single jars with or without stand support are also available.
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.
MANUAL SORTING DEVICE for salmonid eggs
Formerly
and originally developed at the Austrian Institut of Fisheries Economy in Scharfling, this
handheld egg sorting device 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 (with water) into the plexiglass collecting unit. The collected eggs are
stored in the collecting unit (with sieve) and the water overflows at the at the hose,
which hangs to the bottom. 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 SORTING MACHINE with fiber optics and infrared light
This fish 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 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.
