Pumping
When using a fish pump to transfer fish to the counter it is important to ensure an even flow of fish
and water. Uneven delivery of fish to the counter can cause inaccurate counting as the number of
fish may exceed the capacity limits.
It is also important to test the counter on the correct fish size settings pumping water only to
ensure excess water does not create over-counting and adjust pump as required.

7.2 “Test with water only”
6.1 Vacuum Pumps
When using larger vacuum pumps it may be necessary to provide additional dewatering or a buffer
tank. Short bursts of many fish can overload the counter and both excess water and white water
can affect the performance of the counter particularly when counting smaller fish.
6.2 Netting
When netting the fish into the counter it is similarly necessary to supply a sufficient amount of
water for gentle handling of the fish and maintain an even flow of fish over the curved counting
channel.
