Effects of electrofishing for Ensis spp. on benthic macrofauna, epifauna and fish species. SR652

Summary

This report summarises the results of experimental work carried out as part of “Design and Trials of Electrofishing System for Razorclams – FIFG 57437 and Seafish IPF funding project C85”. The aim of the project was to design and trial methods of harvesting Ensis spp. using electrical stimulus with the intention of providing a more environmentally benign alternative to existing hydraulic and toothed dredges. The results of this study demonstrate that the effects of electrofishing gear employing relatively low DC voltage and amperage can be effectively used in the harvest of Ensis spp. without serious negative effects on the epifaunal and macrofaunal benthic community.
