A feeding trial was conducted to evaluate the influences of dietary nutrient composition on the compensatory growth of Blunt Snout BreamMegalobrama amblycephala. Three diets were tested: a control, a high-protein (HP), and a high-protein and carbohydrate (HPC) diet. Each of the three diets was fed to Blunt Snout Bream (initially weight, 24 ± 0.50 g) for 60 d using either satiation feeding (in which fish were fed daily) or restricted feeding (no feeding for 3 d followed by feeding for the next 12 d). The weight gain of fish fed the HP and HPC diets was significantly higher than that of fish fed the control diet. In addition, restricted feeding led to significantly less weight gain than daily feeding with the control and HP diets. However, there was no significant difference between the two feeding regimes in the weight gain of fish fed the HPC diet. The feed conversion ratio of fish fed the control diet was significantly higher than that of fish fed the HP and HPC diets. Moreover, the ratio was significantly lower with restricted feeding than with satiation feeding. Whole-body composition was not significantly different among treatments. Fish subjected to the restricted feeding regime had an elevated hepatosomatic index compared with fish fed to satiation. On the whole, the HPC diet could improve the compensatory growth of fish without altering their whole-body composition, and compensatory growth has the advantage of improving feed efficiency and nutrient retention.
