الوصف: We describe the 1994 and 1995 releasable bycatch (bycatch) of sharks (Carcharhinidae and Sphyrnidae) in the U.S. Gulf of Mexico fishery for gulf menhaden Brevoortia patronus. “Releasable bycatch” is defined as catch of nontarget species observed in the purse seine from the time it is brought alongside the carrier ship until all the catch is pumped into the hold and the net is cleaned. Shark bycatch in the gulf menhaden fishery was positively skewed, 726 sharks being observed in 30% of the fishing sets sampled. Ten species of sharks were identified, blacktip sharks Carcharhinus limbatus being the most common. Approximately 20% of sharks were not identified to species. At the time of release, 75% of the sharks in the bycatch were dead, 12% were disoriented, and 8% were healthy. An annual bycatch of approximately 30,000 sharks for the fishery was estimated for the 1994 and 1995 fishing seasons. By means of a logit model, the likelihood of observing shark bycatch was explained by spatial and temporal...
