Summary:

Cod traps equipped with pingers resulted in a reduction in collisions with humpback whales (Megaptera novaeangliae) in Newfoundland, Canada. Traps with alarms caught more fish than traps without alarms.

Field Studies:
Location Fishing gear Reduction technique Bycatch species Effect on bycatch species Catch Effect on target catch Type
Canada Traps Acoustic pingers Large Cetaceans (maximum length > 7.5 meters) Decreased collisions Cod Increased cod catch In the wild
