Indicator 2.4.14

This Indicator requires the UoC to ensure that fish counting procedures achieve a minimum accuracy of 98%, meaning that the error margin must not exceed 2% and applies to both manual and automated counting methods.

The total number of fish at key stages of production (e.g. stocking and harvesting) needs to be counted.

The actual count should be within 2% of the true number (e.g. if 100,000 fish are stocked, the count must be between 98,000 and 102,000).

Acceptable counting methods include e.g.:

The UoC shall demonstrate that fish are counted at key stages of production (e.g. stocking and harvesting) using a method that achieves 98% accuracy.

If automated systems are used, ensure they are regularly calibrated.

Documentation of counting procedures, accuracy checks and error rates.

Results of fish counts at key stages of production have been presented.

That calibration of the counting method is conducted.

Documents are maintained to record counting procedures, accuracy checks and error rates.
