| Abstract |
Small-mesh fishing for squid in Nantucket and Vineyard Sounds during the springseasonal fishery result in high catch and discard of undersized flounder and scup,both important commercial and recreational fishery species. This study was designed to assess the extent of bycatch and discard in the Loligo pealeii squid inshore fisheryand to describe and document the behavior patterns of squid and non-target fish inrelation to fishing gear. Bycatch rates vary spatially and temporally but over 30% byweight of total catch are discarded at sea. The main bycatch and discard speciescomprise flatfish (summer flounder Paralichthys dentatus and winter flounderPseudopleuronectes americanus), scup (Stenotomus chrysops) and butterfish(Peprilus triacanthus). Videotape recordings and behavioral analysis of squidreactions have shown that squid display classical herding behavior and considerableswimming endurance in the forward part of the net. Loligo are shown to rise whendropping back towards the codend and in some cases to turn and rise on tiring. Thisbehavior may be used to separate squid from the main bycatch species. Separatortrawl test-trials have demonstrated that clear separation between squid and bycatchspecies can be achieved by simple gear modifications. |
