On electrical fishing for brown shrimp (Crangon crangon)

Sea trials with the electro-net showed that the raised groundrope created an escape route for most fish species regularly caught in shrimp trawls, while the electric field made the shrimps tail-flip high enough to be caught. The electro-net with raised groundrope and small meshes in the top panel gave satisfactory results. The losses of commercial shrimp catches were negligible. Part of the undersized commercial fish catch could escape and non-commercial fish and invertebrates were caught in lower numbers compared to the standard gear. Electric fishing can be a practical alternative to the standard shrimp trawl and could be an acceptable balance between the economic interests of the fishermen and the ecological demands of the marine ecosystem.
