Electrofishing is a type of monitoring which uses electricity to temporarily cause fish to swim towards an operator in order to catch them. After the survey, the fish are released back in to the water unharmed.  The use of semi-quantitative electrofishing can indicate the size and age structure of fish  populations and allow us to evaluate habitat conditions.

We use backpack electrofishing equipment to assess juvenile fish stocks in shallow reaches of rivers. We record the number, size and species of the fish we catch. Water quality and habitat conditions are also logged and the data we collect is made available to our partners and the public.

We focus our electrofishing surveys to places where we have carried out improvements, to see how effective our habitat work is, although we also investigate suspected problem areas.Monitoring sites button

Volunteers help us carry out our electrofishing programme every summer.
