Effect of dietary vitamin C on the growth and survival rate of walking catfish Clarias batrachus (Linnaeus)

Abstract

The aim of the study was to evaluate the effect of dietary vitamin C in 3 levels (T2-
500, T3-1000, T4-1500 mg vit C) per kg feed on the growth and survival rate of walking catfish
(Clarias batrachus) in aquaria system. Clarias batrachus fingerling having an average weight of
6.11± 0.47 g were reared in aquaria for a period of 11 weeks fed on diets containing 35%
protein. The highest survival rate was found in T? and lowest in T?. Best growth performance
was found in T? followed by T?, T? and T? (control). Best on the findings of the present study it
is recommended to supplement 1500 mg vitamin C/kg feed containing diet for C. batrachus.
