【 摘 要 】

A completely randomized experiment was run to evaluate the effect of methionine and lysine supplementation on the pejerrey (Odontesthes bonariensis) fingerlings performance. Four treatments were compared: Diet T1 control, with available contents mehionine and lysine in products used in formulation of diets; Diet T2 supplemented with 4.76% of DL- methionine; Diet T3 supplemented with 4.76% of L- lysine and Diet T4 with 4.54% of DL methionine and 4.54% of L lysine. Resulted showed that diets containing methionine were more efficient than control diet and diet with lysine only. Control diet did not differ from diet with lysine supplementation only. It is shown that contents of available lysine in products used in the formulation of diets meet pejerrey fingerlings requirements. Amounts of methionine in control diet are insufficient for fingerlings growth. A supplementation of this aminoacid is required to maximize performance.
