Abundance and size of brown shrimp within the shallow (less than or = 7.3 m) waters off Galveston, Texas

Abstract

Catch rates and mean lengths of brown shrimp (Penaeus aztecus) collected at various depths within the 7.3 m zone before, during and after the 1982 Gulf closure were analyzed. No difference in catch rates among the depths sampled were detected. Mean lengths of shrimp in all depths increased throughout the study. Movement from Galveston Bay corresponded closely with the 25 May - 14 July coastwide closed season.
