Based on 54 recaptures of 488 tagged fish, fish tagged in northwest Trinity Bay did not frequent East or West Galveston Bay. Fish moved toward the Gulf of Mexico in late spring and summer, perhaps to feed or as part of a spawning migration, then returned to the tagging site in fall. The fitted relationship between distance traveled (Y) and Julian recapture date (X), Y-5 9.87 + 50.58 1 sin (0.98 (X-90)) 1, was significant (P lt 0.01) and explained 37% of the variation in Y. The possibility of one population and a spatial separation of fish into at least two estuarine groups can not be eliminatedClimatology: Environmental Sciences; Ecology: Environmental Sciences; Estuarine Ecology: Ecology,Environmental Sciences; Marine Ecology: Ecology,Environmental Sciences; Mathematical Biology: Computational Biology; Nutrition; Reproductive System: Reprodu;Cynoscion nebulosus [Osteichthyes];ESTUARINE POPULATION; FEEDING; GULF OF MEXICO; MATHEMATICAL RELATIONSHIP; MIGRATION PATTERN; NORTH ATLANTIC OCEAN; SEASONALITY; SPAWNING;Osteichthyes: Animals,Chordates,Fish,Nonhuman Vertebrates,Vertebrates;[04500] Mathematical biology and statistical methods;[07504] Ecology: environmental biology - Bioclimatology and biometeorology;[07508] Ecology: environmental biology - Animal;[07510] Ecology: environmental biology - Oceanography and limnology;[07512] Ecology: environmental biology - Oceanography;[12100] Movement;[13202] Nutrition - General studies,nutritional status and methods;[16504] Reproductive system - Physiology and biochemistry;[85206] Osteichthyes;[85206] Osteichthyes,Pisces,Vertebrata,Chordata,Animalia;Journal
