Small-Scale Fisheries Bycatch Jeopardizes Endangered Pacific Loggerhead Turtles
BACKGROUND Although bycatch of industrial-scale fisheries can cause declines in migratory megafauna including seabirds, marine mammals, and sea turtles, the impacts of small-scale fisheries have been largely overlooked. Small-scale fisheries occur in coastal waters worldwide, employing over 99% of the world's 51 million fishers. New telemetry data reveal that migratory megafauna frequent coasta...
متن کاملMulti-year tracking reveals extensive pelagic phase of juvenile loggerhead sea turtles in the North Pacific
BACKGROUND The juvenile stage of loggerhead sea turtles (Caretta caretta) can last for decades. In the North Pacific Ocean, much is known about their seasonal movements in relation to pelagic habitat, yet understanding their multi-year, basin-scale movements has proven more difficult. Here, we categorize the large-scale movements of 231 turtles satellite tracked from 1997 to 2013 and explore th...
متن کاملSize scaling in western North Atlantic loggerhead turtles Published as ”Size Scaling in Western North Atlantic Loggerhead Turtles Permits Extrapolation
Sea turtles face threats globally and are protected by national and international laws. Allometry and scaling models greatly aid sea turtle conservation and research, and help to better understand the biology of sea turtles. Scaling, however, may differ between regions and/or life stages. We analyze differences between (i) two different regional subsets and (ii) three different life stage subse...
متن کاملImpacts of fisheries bycatch on loggerhead turtles worldwide inferred from reproductive value analyses
1. Fisheries bycatch has been implicated in declines of many long-lived marine vertebrate populations, but bycatch impacts on these populations vary according to spatio-temporal overlap in fisheries operations and critical ontogenetic habitat, as well as to characteristics of fishing gear. 2. To provide a framework for comparing the relative impacts of different fisheries on populations of logg...
متن کاملPathology 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...
