Abstract

Observer data from the US pelagic longline fishery were examined to describe the characteristics of elasmobranch bycatch off the southeastern coast of the United States from 1992 to 1997. Elasmobranch bycatch was dominated by silky sharks (Carcharhinus falciformis). Substantial proportions of dead discards were also observed for other pelagic species, including night sharks (C. signatus) and bigeye thresher sharks (Alopias superciliosus), as well as several coastal species, notably dusky sharks (C. obscurus). Comparison of mean lengths to published estimates of size-at-maturity indicates that, for many species, bycatch in this area is immature.
