The aim of this study was to determine the carcass chemical composition and amino acid profile of carcasses and the level of activity of the digestive enzymes of Khajoo (Schizothorax pelzami). To this end, Khajoo fish were harvested from the north-eastern region of Iran, and after preparation, relevant analyzes were carried out in three longitudinal classes (8-12, 12-16, 16-20 cm).As the fish size increased, carcass protein content decreased significantly (p <0.05), and the amount of crude fat and ash increased (p <0.05). The results showed that arginine and leucine are the most abundant and methionine is the least amino acids in the Khajoo fish carcasses. With increasing fish weight, the amount of leucine, lysine, threonine and methionine of the carcasses increased significantly (p <0.05). Total protease enzyme have the highest amount of activity and the level of activity of the total protease and lipase enzymes showed a significant increase (p <0.05) with fish body weight gain. The results of this study showed that Khajoo fish could be considered as a species with omnivorous eating habit which tending to carnivores.Information on the chemical composition and amino acid profile of carcass of Khajoo could be applied as a template for formulation of dietary foods.
