Using acoustically visible gillnets to reduce bycatch of a small cetacean: first pilot trials in a commercial fishery
Bycatch of protected species, particularly small cetaceans, in gillnets is a worldwide concern. One hypothesis for this is that echolocating cetaceans entangle because they do not perceive conventional gillnets as impenetrable barriers, owing to the gillnet’s faint echo. A gillnet modified for impro...
