Abstract: Growth of the captive-reared green sea turtle, Chelonia mydas, fits a logistic by weight growth equation reaching an asymptotic weight at approximately 12.5 years with an average weight of I 56 kg. The relationship of weight to carapace length and width is inter-dependent with age and size of the turtle. Mean age at sexual maturity for the captive green turtle is estimated at 16 years, and it is projected that 96% of a captive population would begin nesting at 25 years of age. Although growth of mature green turtles reaches an asymptote at 1 2.5 years, captive, mature green turtles continue to increase in weight at a rate of 3 kg/yr.
