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.
JAR SYSTEM made from stainless steel
This well designed systems are
made of stainless steel and are equiped with "zougg or weiss" glass jars wich
can be removed and serviced seperatly. Through the inlet tank on top, all jars can be
individually supplied with water. The tank and feets are soemwhat 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. After hatching the larvae
usually leave the jars by themself with the water flow or are removed by the farmer from
the jar. 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 accessoire.

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.
|BREEDING THROUGHS for salmonid eggs
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.
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 vital 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 and healthier, they also have less deformations and lower mortalities.

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.
MACHINE with fiber optics and infrared light
This fish egg sorting machine uses the
most current technology to sort 100,000 salmonid 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.
Quality is our motto ... and your profit!
