The objective was to evaluate the productive response of two extruded balanced feeds in the first stage of steelhead trout fries (Oncorhynchus mykiss). The experiment was carried out in the ponds of the Vinchos hatchery, located in the district of Canchayllo, province of Jauja, region Junín, belonging to the SAIS “Túpac Amaru” Ltda. N°1. The balanced foods used in the experiment were: La Molina extruded food (T1) that is made in the Balanced Food Plant of the La Molina National Agrarian University, and Nicovita extruded food (T2) from the Vitapro S.A company. The evaluation was carried out during 64 days, for which 85,836 steelhead trout fingerlings with an average weight of 142 g were used. These experimental fish were distributed in two treatments with three repetitions of 14,306 fish each. The evaluation parameters were biomass gain, feed intake, feed conversion, survival, growth rate and cost per kilogram gained. The statistical model used was the Completely Random Design (D.C.A.), the analysis of variance and the Tukey test were performed to evaluate the differences between the means of the treatments and for the survival parameter, the chisquare was used. The results obtained for the evaluated parameters feed intake, feed conversion, survival and cost per kilogram gained showed significant differences (α<0.05); however, in the parameters, weight gain and growth rate, only a higher numerical performance is observed for treatment 2 (T2). In conclusion, the results obtained indicate that a better productive response was obtained with treatment 1 (T1) by obtaining a higher percentage of survival and lower cost per kilogram gained in the first stage of steelhead trout fries.
