The experiment was run on carp individuals in their second year of life. The fish were randomly divided into two groups fed two different isoprotein diets, one with increased fat level (Group I) and the other with increased carbohydrate level (Group II). Cortisol, total protein and protein fraction contents, AspAT and AlAT activities, and body composition and weight increments were monitored. Statistically significant differences between the two experimental groups were found in cortisol content, albumin level, blood AspAT and AlAT activities as well as in dry weight, total protein, and fat contents of the fish body.
