The European Commission ignored scientific advice when it allowed the use of electric shocks to catch fish in British waters, an investigation shows.

British fishermen have reported that the sea is a “graveyard after a visit by the overseas boats. They tow electrodes that fire bursts of electricity into the seabed to force out sole and plaice from the mud.
