Resumen

BADILLO-ZAPATA, Daniel et al. Protein and lipid requirements for growth of juveniles of the native fish Dormitator latifrons (Richardson, 1844). Ecosistemas y recur. agropecuarios [online]. 2018, vol.5, n.14, pp.345-351. ISSN 2007-901X.  http://dx.doi.org/10.19136/era.a5nl4.1554.

Dormitator latifrons is a fish 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 significant differences (p > 0.05) were detected in the growth, survival and proximal composition of the fish muscle. The apparent digestibility of the diet with 30% protein and 8% lipids was significantly higher than the rest of the diets, so it is considered sufficient for adequate growth of D. latifrons juveniles.

Palabras llave : D. latifrons; lipids; native; nutrition; protein.
