Risk Factors for Seabird Bycatch in a Pelagic Longline Tuna Fishery

Regulations often require that bycatch of threatened species be released; but, if animals are already dead, their release serves no conservation purpose. We exa...

Tropical tuna fisheries are among the largest worldwide, with some having significant bycatch issues.
