Incidental Catch of Mollusks Associated with Shrimp Fishery in the Gulf of Tehuantepec, Southern Mexican Pacific - Abstract
This study presents the species of bivalves and gastropods of commercial interest and potential use recorded in 33 sampling stations in the Gulf of Tehuantepec, southern Mexican Pacific. The collections were performed with a trawling net on board of the shrimp vessel FIPESCO 63. The relative abundance and the biological value index (BVI) of every species was calculated as an indicator of the importance of the mollusks based on the abundance and frequency of the species in the samples. A total of 832 individuals of 59 species (18 bivalves, 41 gastropods) from which most are of commercial or potential interest. The most abundant were Argopectenirradians, Harpacrenata, Granolariasalmo, Ficusventricosa, Crepidulaexcavata, Hexaplexbrassica, Malearingens, Crucibulumlignarium, Fusinusdupetitthouarsi,Tonna sp., Olivasplendidula, Melongenapatula, Conuspatricius and Crucibulumpersonatum. Comments and suggestions are made on the present use of the species and the possibilities of exploitation in aquaculture and fishery taken into consideration previous experiences with these and other species in different regions of the Mexican Pacific and the rest of the world.
