Bioscanner Fish Counter

Highly Accurate and Gentle Treatment of Fish

Bioscanner Fish Counter

Fish of all species are counted stress free and remain in water at all times. The Bioscanner is highly accurate and can be utilized with fish from 3g to 6kg. Accurate information on the number and size of farmed fish is very important in modern aquaculture. Biomass data on the fish in tanks and pens makes it possible to monitor production and facilitates management and planning. The Bioscanner has been counting fish worldwide since first introduced in 1984 and is the standard in the automated counting of live fish.

How it works

The two main functions are the V-form and the curve form. As the fish come out of the basin they are close together, and have to be separated to be counted accurately. The V-form ensures that the fish cannot turn around, and also that they are not crowded together. The curved form accelerates the fish down the channel. If two fish are close together in the beginning the one that is little bit ahead will accelerate faster and this causes a separation of the fish.

For correct operation the amount of water must be adjusted to the size of the fish. Better separation of the fish will be achieved if not too much water is used. However, sufficient water must be used to flush the fish smoothly down the channel.
