What’s the catch? Patterns of cetacean bycatch and depredation in Hawaii-based pelagic longline fisheries

Shark Depredation and Unwanted Bycatch in Pelagic Longline Fisheries

Evolving Fisheries: Today’s Bycatch is Tomorrow’s Target Catch Escolar (Lepidocybium flavobrunneum) Catch in the U.S. Pelagic Longline Fishery

Wildlife and fisheries management are based upon economics: the law of supply and demand controls the direction of commercial fisheries. In the U.S. pelagic longline fishery, one example of a bycatch species that has received little research attention because of its lower economic value is the escolar (Lepidocybium flavobrunneum). Given its importance as a secondary market species, the main obj...

Temporal patterns of target catch and sea turtle bycatch in the US Atlantic pelagic longline fishing fleet

Sea turtle bycatch in pelagic longline fishing gear is an ongoing threat to the conservation of sea turtle populations. However, these bycatch events do not occur uniformly in space or time. Leatherback (Dermochelys coriacea) and loggerhead (Caretta caretta) bycatch rates reported in large fishing regions exhibited different degrees of interannual variability. Target catch and sea turtle bycatc...

Pathology and distribution of sea turtles landed as bycatch in the Hawaii-based North Pacific pelagic longline fishery.

We examined the gross and microscopic pathology and distribution of sea turtles that were landed as bycatch from the Hawaii, USA-based pelagic longline fishery and known to be forced submerged. Olive ridley turtles (Lepidochelys olivacea) composed the majority of animals examined, and hook-induced perforation of the esophagus was the most common gross lesion followed by perforation of oral stru...

Dolphinfish Bycatch in Spanish Mediterranean Large Pelagic Longline Fisheries, 2000–2010

The aim of this paper is to describe the dolphinfish bycatch rates in the longline fisheries of the Western Mediterranean and modelling the nominal bycatch abundance and distribution of dolphinfish from the Spanish Mediterranean as a function of technical, geographical, and seasonality factors. Our results indicate that the impact of the pelagic and semipelagic longline on the dolphinfish popul...
