Abstract
A study of the biology of the gray snapper was based on the examination of 849 fish collected primarily from the sport fishery of Everglades National Park. Gray snappers from Park waters ranged from 1 to 5 years of age, with age‐groups II and III making up 62 and 29 percent of the catch. Mean lengths for each age group, age and length at recruitment into the sport fishery, length‐weight relationship, and sex ratio of gray snapper are given. All Everglades Park fish were immature. The stomachs of 200 fish were examined for food contents. Crustaceans made up 61.6 percent of food items by number and 76.7 percent by volume, shrimp occurring most frequently. Fish and crabs occurred in 34 and 27 percent of the stomachs containing food.This publication has 0 references indexed in Scilit:
