Data were analyzed for variations between area, size of fish, and season by using percentage volume and percentage frequency. of occurrence. About 59% of the stomachs were empty. The percent volume of fish ranged from 95.1% in northwest Florida to 99.8% in south Florida. Twenty-five families of fish were represented in the diet. Six families were oominant: Clupeidae, Sparidae, Carangidae, Sciaenidae, Mugilidae, and Haemulidae. The dominant fish species were Sardinella aurita, Iagodon rhomboides, and Decqpterus punctatus. Invertebrates never exceeded 5% of the total volume or 12% in occurrence in any area. Relatively minor differences in diet among size classes and among seasons were noted; however, between areas the diet varied considerably.
