Full Title
New information on Hector?s dolphin bycatch from camera monitoring
Author
Elisabeth Slooten
Authors Summary
Camera monitoring indicates that Hector?s and Maui dolphin bycatch in trawl fisheries has been substantially under-estimated. Past estimates have been based on one observed trawl death in 1998, due to very low levels of observer coverage. On-board camera monitoring has detected much larger numbers of trawl captures, with nine Hector?s dolphin deaths during 20 September 2023 ? 29 February 2024, including a mother and calf pair. Because the trawl fishery started much earlier than the gillnet fishery, this new information indicates that substantial fisheries bycatch started much earlier than previously thought, and therefore the level of depletion of Hector?s and Maui dolphin populations is worse than previously thought. Maui dolphin bycatch is estimated to remain on the order of one individual per year, which is 10x the PBR.
