During February 1976-November 1981, 2040 spotted seatrout (Cynoscion nebulosus ) were caught for tagging with hook and line at Bastrop Marina on Bastrop Bayou in the Galveston Bay system. The subsequent tag return rate was 8.6% (176 individuals). Tag recapture data indicate an exit of fish from the Bayou in winter months with a return in the spring, followed by a summer exit and a subsequent fall return. Forward stepwise regression analyses indicate that total length at release, number of warm days free and number of cold days free accounted for 60.28% of the variation in total length at recapture. Survival of spotted seatrout tagged in fall ranged from 20-33% per year
