RESULTS AND DISCUSSION
Levels of vitamin C significantly influenced weight
gain of common carps (Table 2).
Weight gain increased with an increase in levels of
vitamin C. SGR of fries also followed the similar pattern as
observed with weight gain. Protein efficiency ratio (PER)
was significantly higher in treatment 2 compared with
other groups and lowest in control group (without
supplementation of vitamin C). Lower feed conversion
ratio (FCR) was observed in treatment 2. Survival rate of
common carp did not differ among the treatments.
Carcass proximate and vitamin C content of fish fed
the various diets are presented in Table 3.
The crude protein content was significantly (P
