--- The purpose of this study was to determine frequency the presentation of anothomohistopathologycal lesions compatibles with metabolic disorders related to energy and proteins in the diet of juvenile Rainbow Trout (Oncorhynchus mykiss ). Forty fish were collected randomly from the one trout hatchery, located in Huancayo-Junín, mainly taking samples of liver, kidney, gill, stomach and spleen. Between the macroscopic findings compatible with metabolic alterations observed with major frequency it was the fatty liver characterized by a brown pale coloration in 67.5% (27/40). As soon as, to the lesions histopatológicas compatible the metabolic alterations were found fat degeneration 97.5% (39/40), predominantly in grade IV and hyaline degeneration in renal tubules, 62.5% (25/40) and only 7.5% in glands gastric stomach. In gills, changes in growth such as hyperplasia (30/40), fusion (29/40) and lamellar atrophy (29/40) by 75% and 72.5% respectively, representing the highest frequency of lesions. Based on the findings, concluded that the lesions compatible the metabolic disorders were observed in a high frequency, principally related to excessive protein as hyaline degeneration in the kidney and stomach, and fatty degeneration in liver for balancing energy. Finally, the lesions on gills suggest an association between metabolic disorders and their polluting effect on the aquatic environment.
