متن کاملCharacteristics and magnitude of sea turtle bycatch in US mid-Atlantic gillnet gear
From 1995 to 2006, US federal fisheries observers deployed aboard commercial fishing vessels in the US mid-Atlantic region documented captures of loggerhead Caretta caretta, green Chelonia mydas, Kemp’s ridley Lepidochelys kempii, and leatherback Dermochelys coriacea turtles in commercial sink gillnet gear. Data collected by these observers were used to characterize sea turtle bycatch in sink g...
متن کاملModeling spatial patterns in fisheries bycatch: improving bycatch maps to aid fisheries management.
Fisheries bycatch, or incidental take, of large vertebrates such as sea turtles, seabirds, and marine mammals, is a pressing conservation and fisheries management issue. Identifying spatial patterns of bycatch is an important element in managing and mitigating bycatch occurrences. Because bycatch of these taxa involves rare events and fishing effort is highly variable in space and time, maps of...
متن کاملMarine mammal bycatch in gillnet and other entangling net fisheries , 1990 to 2011
Since the 1970s the role of fishery bycatch as a factor reducing, or limiting the recovery of, marine mammal populations has been increasingly recognized. The proceedings of a 1990 International Whaling Commission symposium and workshop summarized fishery and bycatch data by region, fishery, and species, and estimated the significance of the ‘impacts’ of bycatch in passive gear on all cetacean ...
متن کاملAddressing fisheries bycatch in a changing world
Fisheries bycatch is a threat to species of marine megafauna across the world’s oceans. Work over the past several decades has greatly advanced our understanding of the species affected, the magnitude and the spatial extent of bycatch. In the same time period, there have been substantial advances in the development of mitigation strategies and best practices to reduce bycatch. In this paper, we...
