Description:"The U.S. Atlantic pelagic longline fleet operates throughout the Gulf of Mexico, along the entire U.S. Atlantic coast over the continental shelf and slope, and in distant water areas including the central North Atlantic and the Canadian Grand Banks. The Atlantic longline fleet is defined as a Category I fishery under the Marine Mammal Protection Act, and it is also the subject of management concerns under the Endangered Species Act due to interactions with leatherback and loggerhea d turtles. Total bycatch of marine mammals and turtles in the longline fishery was estimated for 2005 using data from the pelagic longline fishery observer program and a mandatory fishery logbook reporting program. We applied a delta-lognormal approach to estimate region specific and total annual interactions with protected species for the fishery. During 2005, there were an estimated 351 (233 - 529 95%CI) in teractions with leatherback turtles (Dermochelys coriacea) and 274 (195 - 384 95%CI) interactions with loggerhead turtles (Caretta caretta). The primary marine mammal species interacting with this fishery were pilot whales (Globicephala sp.) with an estimated 294 (180 - 473 95% CI) interactions and Risso's dolphin (Grampus griseus) with 42 (15 - 120 95% CI) interactions. Potential sources of bias and uncertainty in these bycatch estimates are discussed"--Abstract.
