Scallops are commonly caught with toothed dredges which bulldoze the seabed leaving a trail of destruction in their paths.
What is caught in bycatch?
Over 50 species of fish and 60 other species, including crabs and starfish, have been caught accidentally along with the scallops, and are usually discarded. This is known as bycatch. Fishing boats also throw away, or ‘discard’, young fish and those that exceed their fishing quota (the amount they are allowed to catch). Discarding and bycatch are damaging and wasteful activities as the animals are often dead when they are thrown back into the sea.
