Abstract

A 3×2 factorial feeding trial of three DIETARY PROTEIN levels (45, 50 and 55%) and two DIETARY crude ENERGY levels (4200 and 4600cal/g) with three replications was coducted to investigate the proper DIETARY PROTEIN and ENERGY levels for the GROWTH of fingerling Caspian trout (Salmo trutta caspius). Fingerlings with average weight of 3.8±0.1g were fed the experimental diets for 60 days. Results indicated that weight gain, FCR, SGR and PER were affected significantly by DIETARY PROTEIN and enaegy levels (P<0.05). At the constant PROTEIN levels, GROWTH performance of fishes improved as DIETARY ENERGY levels increased (P<0.05) and at the constant ENERGY levels, GROWTH indexes at first increased and then decreased significantly as deitary PROTEIN level increased. GROWTH performance of fish fed diet with 50% PROTEIN and 4600cal/g ENERGY significantly (P<0.05) was better than other treatments. PROTEIN content of fish increased when DIETARY PROTEIN increased but there was no significant difference (P>0.05) between 50 and 55% PROTEIN. Lipid content of fish fed higher PROTEIN levels was significantly (P<0.05) lower than those of fish fed lower PROTEIN levels. Moisture and ash contents of fish were not affected by DIETARY PROTEIN levels. Lipid content of fish fed diet with high-energy level was significantly higher than those of fish fed the low DIETARY ENERGY (P<0.05). This case was converse for body moisture. PROTEIN and ash contents of fish also were not affected by ENERGY levels. It can be suggested that for this size of the Caspian trout, diet with 50% PROTEIN and 4600cal/g ENERGY is appropriate.
