Abstract



An 8-week experiment was conducted to examine the effect of restricted feeding on compensatory weight gain and body tissue changes in fry of the Indian major carp, Cirrhinus mrigala. During the period of feed restriction, the control group was fed to satiation twice a day while feed for the three other groups was completely withheld for 1, 2, or 4 weeks. During the subsequent re-alimentation period, all groups were fed to satiation. At the end of the experiment, fish deprived of feed for two weeks had a significantly ( p<0.05) higher body weight (5.400.20 g) and lower FCR (3.400.20) than the control group (4.550.10 g and 6.750.02, respectively). At the end of the experiment, there were no significant differences in dry matter, protein, lipid, or ash contents among groups, except that fish deprived of feed for four weeks had a significantly ( p<0.05) lower protein content than fish in the other treatments.
