Crecimiento, conversión de alimento y mortalidad de <i>Eretmochelys imbricata</i> (Reptilia: Chelonidae) en estanques artificiales en Costa Rica

Abstract

Growth rates, feed conversion and mortality of cultured Eretmochelys imbricata (hawksbill turtle) were studied in concrete raceways by feeding with fresh fish meal (tilapia) and in duplicate (tanks of 21 m'). The turtles were 11 months old at the begining of the experiment, with and average caparace straight length of 23.64 ± 1.94 cm, an average caparace curved length of 24.15 ± 1.94 cm and an average weight of 1527 ± 2.54 g. The experiment was carried out during six months and a density of 3 ind/m' was used. The equation of Von Bertalanffy for the growth of E. imbricata was LRC= 3.5 + 1
