Individual Fish Counter


Main Control System

Northwest Marine Technology is pleased to introduce the Individual Fish Counter. The system is designed for counting fish when they are being processed by hand, such as for fin clipping or vaccinating. The counter will accommodate fish as small as 0.5 grams.

The counter consists of a Main Control System (below) and up to 12 Individual Counting Stations. The fish are placed individually into the Counting Station funnels (above) and sensors detect passing fish. The Control System tallies the individual counts per station and the total count. In addition, the operator can set a total count that will trip an alarm when reached. This feature will be particularly useful for populating ponds.

The Control System can be used free standing or wall mounted. The Individual Counting Stations can be integrated into most fish handling equipment.
