Se evaluó el efecto de dietas isocalóricas e isolipídicas que contenían 45, 47, 49, 51, 53 y 55% de proteína sobre el crecimiento y supervivencia de subjuveniles de tortuga carey (Eretmochelys imbricata). Se desarrolló un diseño experimental completamente aleatorizado durante 68 días en condiciones controladas de laboratorio y se utilizaron ejemplares con peso promedio inicial de 76 g. Los mayores crecimientos en peso se obtuvieron con las dietas que contenían 49 y 51% de proteína, lográndose crecimientos diarios de 2.8 g. El factor de conversión del alimento varió entre 1.98 y 2.68 y los mayores valores de eficiencia proteica lo alcanzaron los ejemplares que obtuvieron los mayores crecimientos. Se recomienda el empleo de piensos que contengan 49-51% de proteína en la alimentación de subjuveniles de la especie.Diets isocaloric and isolipidics containing 45, 47, 49, 51, 53 y 55% protein levels on growth and survival of hawksbill subjuveniles (Eretmochelys imbricata) were carried out. A totally aleatory randomized experimental design was developed under controlled conditions of laboratory during 68 days, and utilized animals had an average initial weight of 76 g. The fastest growths in weight were reached with diets of 49 and 51% of protein, obtained daily growth in weight of 2.8 g. The feed conversion ratio varied between 1.98 y 2.68 and the best protein efficiency ratio was reached for the animals that attained the bigger growths. It was recommended to feed with artificial diets which contain 49-51% protein levels in the feeding for sub juveniles of the species.
