The following types are available as standard:

VACUUM PUMPS with or without weighting system

For the lifting of fishes to grading machines and/or the loading of transport tanks etc. this fish vacuum pump is especially suitable. The functional principle is relative easy but effective, which helps to reduce unnecessary breaks and expensive repairs. The fishes (up to 5 kg in body weight and up to 16 t/h) are sucked up to 5 m in height, via an inlet funnel over a 6 m long suction hose (150 or 200 mm Ø) by two vacuum tanks (each 150 l) which work in exchange. By a 0.6 m2 large separator with 8 mm grid distance, the fishes are separated from water and glide so directly into a transport tank etc. The water and fishes leave the unit by a hose (water outlet 200 mm - fish outlet 230 mm Ø), which can be adjusted in height from 90-150 cm. The live fish pump has dimensions (L x W x H) of 360 x 155 x 230 cm) and a weight of approx. 650 kg. The motor (400 V/50 Hz, 4.0-7.5 kw) is integrated into the galvanized steel housing. The 3 transport wheels and telescopic legs guarantee that the unit stands well and is safe.

As option, there is a scale available, which weights the fishes (up to 1 kg in body weight and up to 6 t/h) after the fish pump. The weighting results (accuracy +/- 50 g) can be added and easily read from the display. The fish scale has dimensions (L x W x H of 165 x 103 x 165 cm) and a weight of approx. 190 kg.

MANUAL GRADING DEVICE for fry and fingerling

Originally developed at the Austrian Institute of Fisheries Economy in Scharfling, this simple but effective sorting device is perfectly suitable for sorting of fry and fingerlings in small to medium fish hatcheries and already used for centuries. The distances of the grating can be easily adjusted by shaping the device to a rhomb. The seawater resistant impregnated wooden frame keeps floating and an exact distance between the aluminum grates. The device is placed in one tank, than fishes are just put into the device, the smaller fish go thru the grates while larger ones can't pass and are placed in another tank. For grading into more than 2 size classes, the grates are enlarged by simply pushing the whipable scale-bar, and so on.

Available in two sizes:

AUTOMATIC GRADING MACHINES with moving fingers

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 channels 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 optionally). The machines are mounted on a trolley with 2-3 wheels. Equipped with 380 V/50 Hz motor (230 V on request).

The following types are available as standard:

Some graders are also available with an integrated fish counting system.

ELECTRONIC COUNTERS for fry and fingerlings

This 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.

The following types are available as standard:

FISH COUNTERS for graders or pipes

This newly developed fish counter series made of aluminum and plastic was specially developed to count fast (about 3-5 t/h) and accurately (over 97 %) live fish like salmonids, cyprinids and percids (from 1-5000 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 (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.
