Abstract:
This report contains the results of a study into best practice for electric fishing operations, using information taken from literature and Environment Agency regions. The Environment Agency’s Electric Fishing working group identified a need to develop best practice for electric fishing operations, in respect of choice of equipment and output characteristics needed to achieve good fish capture efficiency and minimum incidence and severity of fish damage at all times. Aspects in need of investigation were: 1. Output type and waveform; 2. Frequency and power output; 3. Anode size and shape, cathode size and shape; 4. Choice of options available regarding gear configuration (single anode, multi-anode, boom-mounted etc); 5. Post-capture fish care. Overall the aim of the project was to: - Collate existing published information regarding optimal equipment settings; - Determine from Agency staff the pool of knowledge that exists regarding practical equipment usage; - Determine from empirical experimentation and published literature the most appropriate combinations of electric fishing equipment and output settings for use under the range of conditions likely to be encountered in the UK; - Promote the best practice in electric fishing with the currently available equipment. The project revealed that much of literature on electric fishing, especially in respect of harmful effects on fish, is contradictory, and there is a paucity of literature on electric fishing of common UK species other than salmonids.
