The project had four major goals and objectives:  (1) to determine percent composition by weight and number of target species (shrimp) and all non-target species caught in commercial shrimp trawls within bays on the northern and mid-Texas coast, (2) to determine the catch rate and mean size of target and non-target species, (3) to compare average percent composition of commercial bay trawl species to species composition in the Texas Parks and Wildlife Department's (TPWD) fishery independent bay trawl surveys, and (4) to compare 1995 bycatch composition and magnitude on the northern and mid-Texas coast during the 1995 spring and fall shrimping seasons to preliminary single-year bycatch data collected during 1992 in Galveston Bay and during 1993 in Corpus Christi Bay. 

This project determined percent composition, catch rate, and mean size of commercial shrimp seasons in Galveston Bay, Matagorda Bay, San Antonio Bay and Corpus Christi Bay. ,It also conducted statistical analyses on percent composition of major commercial shrimp and bycatch organisms collected in commercial and TPWD samples during the spring and fall shrimping seasons on the northern and mid-Texas coast. This knowledge will assist in the management of Gulf of Mexico recreational and commercial marine organisms and associated fisheries, as well as in environmental issues and management regimes related to Texas Bay and Gulf of Mexico ecosystems.
