ABSTRACT In southern Iberia (NE Atlantic), cetacean bycatch is reported in several fisheries, whereas depredation by bottlenose dolphin (Tursiops truncatus) is commonly observed in bottom set‐net fisheries. This study tested the effectiveness of acoustic deterrent devices in discouraging small cetac...
