The biology of gray snapper, Lutjanus griseus, in Everglades National Park was studied from 1959-1960. Based on 849 fish collected mainly from the Everglades National Park sportfishery, snapper ranged in age from 1-5 years with age groups I and II making up 62 and 29% of the catch. Mean lengths, age and length at recruitment, length-weight relationship, and sex ratio were determined. Data are presented concerning habitat, and salinity and temperature ranges including cold water induced mortality. Stomach contents of 200 snapper indicated Crustacea dominated by frequency and volume with shrimp occurring most frequently. Fish and crabs were the second and third most important food groups by frequency. Study Period: April 1959-April 1960; Habitat: Coastal mangrove, estuarine bays, and lagoons; Study Type: Semi-quantitative and quantitative; Biological Component: Fish; Gear Type: Hook & Line, Trawl; Temporal Frequency: Monthly; Abiotic Parameters Measured: Salinity, temperature; Dominant Taxon/Taxa Studied: Lutjanus griseus.
