| Summary: | Population structure, food habits, and spawning activity of 1026 gray snapper, Lutjanus griseus, were studied from sportfishermen catches in ENP from November 1978 through January 1980. Results showed that fish age ranged from 1-7 years, 2-3 year old fish dominated the catch, and recruitment was complete by age 3. Fish taken from Cape Sable were older than fish taken from other areas. Growth varied between sexes and among areas of capture; females were larger than males at ages 1-2. | |
| Summary: | Fish taken from hypersaline areas were larger than fish taken from brackish waters. Annual survival rate of fully recruited fishes was s = 0.28; male survival was higher than that for females. Gray snapper apparently spawn outside of park waters. Their diet, consisting mainly of fish, shrimp, and crabs, varied with age, among seasons, and areas of capture. Comparison of this study with an earlier study of park gray snapper (Croker 1960, no. 63 in bibliography) showed increases in survival and longevity since 1960. | |
