Graders & Sorters

MANUAL GRADING DEVICE for fry and fingerling

Grading deviceOriginally 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:

Type Small Large
Device size cm



Grading distance mm





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).

Counters & Scales

ELECTRONIC COUNTERS for fry and fingerlings

Fish 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.

The following types are available as standard:

Type Micro Macro
Fish size g 0,5-5,0 5,0-50,0
Capacity/h 30.000-35.000 25.000-60.000

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 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. A reception tank/funnel with 160/200 mm diameter pipe connection is available as accessory, as well as an inlet hopper for manual use.

PIPELINE COUNTERS for many fishes

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

This save and powerful electric fish catching machines are successfully in use on all continents since over 30 years. Through the various and sometimes problematic areas of use, a wide range of electrocatchers was developed which will match nearly any requirement. All our devices are build to EN 60335 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 "Deadmanswitch" (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 backcarry units additionally have a tilt-switch. 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 and lower deformations of fishes than 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 were created, where the impulse frequency and volts can be adjusted (via motor turns or switch). The backpack 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 motor-driven back-carry- or stand-devices with direct- and/or impulse current with an outgoing power of 250-15.000 Watt (5-160 kw/impulse at 10-100 impulse/sec.), and a current of 100-1000 Volt with a weight of 5-100 kg and for a water conductivity of 50-20.000 µS. As accessories are available: 30-60 cm Ø stainless steel anodes with RGP-electro handles up to 6 m in length, copper cathodes with cable and connector, plastic cable drums for up to 100 m cable, hand- or foot- Dead-man-switch, electro-rubber outfit (tested to 1000 Volt) as well as tanks and lights.

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