Higher amounts of total lipids (LIP/TBM, p < 0.05) and lower amounts of total proteins (PRT/TBM, p < 0.05) were detected only in Hi75 and Hi100 liver samples; an increasing trend in fatty acids amount (FA/TBM, p < 0.05) was detected in all livers samples of fish fed diets with increasing BSF meal inclusion levels, together with a decrease of both carbohydrates (COH/TBM, p < 0.05) and phosphates (PH/TBM, p < 0.05); lower levels of glycogen (GLY/TBM, p < 0.05) were found in Hi50 and Hi75 groups.
