RESUMEN. Dormitator latifrons es un pez con potencial comercial que habita ambientes con climas tropicales y subtropicales desde el sur de California (EEUU) hasta Perú. El objetivo fue determinar los requerimientos nutricionales de proteína y lípidos para el crecimiento de juveniles, se elaboraron cuatro dietas experimentales con contenidos de proteína del 30 y 40%, y lípidos del 8 y 16%, con tres repeticiones por tratamiento. Se realizó el análisis proximal de las dietas experimentales, del músculo al inicio y al nal del experimento y se determinó la digestibilidad aparente. No se detectaron diferencias signicativas (p > 0.05) en el crecimiento, supervivencia y la composición proximal del músculo de los peces. La digestibilidad aparente de la dieta con 30% de proteína y 8% de lípidos fue signicativamente superior al resto de las dietas, por lo que se considera suciente para un adecuado crecimiento de juveniles de D. latifrons.ABSTRACT. Dormitator latifrons is a sh with commercial potential that inhabits environments with tropical and subtropical climates from southern California (USA) to Peru. The objective was to determine the nutritional requirements of protein and lipids for the growth of juveniles; four experimental diets were prepared with protein contents of 30 and 40%, and lipids of 8 and 16%, with three repetitions per treatment. Proximal analysis of the experimental diets, of the muscle at the beginning and at the end of the experiment, was carried out and the apparent digestibility was determined. No signicant dierences (p > 0.05) were detected in the growth, survival and proximal composition of the sh muscle. The apparent digestibility of the diet with 30% protein and 8% lipids was signicantly higher than the rest of the diets, so it is considered sucient for adequate growth of D. latifrons juveniles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
