A 60-days feeding trial was conducted to assess the growth and metabolic enzyme activity in Clarias batrachus fingerlings fed with graded levels of digestible carbohydrate (DC). Ninety fingerlings (90) of Clarias batrachus (Av. Wt. 5.5g) were stocked in three distinct experimental groups in triplicates following completely randomized design. Three experimental diets viz. 20 % DC (T1), 30% DC (T2) and 40% DC (T3) were fed to Clarias batrachus fingerlings. The lowest weight gain was observed in the group fed with 20% DC (T1). Specific growth rate (SGR) and protein efficiency ratio (PER) were significantly (p<0.05) higher in T2 and T3 groups than the T1 group. Activities of intestinal amylase and liver Glucose - 6 - phosphate dehydrogenase (G-6-PDH) enzymes were significantly higher (p<0.05) in T3 group. Both T2 and T3 groups showed higher aspartate amino transferase (AST) and alanine amino transferase (ALT) activities in both liver and muscle tissues. No significant change was observed in the hexokinase activity in the liver and muscle tissues (p>0.05). Hence, from the findings of the present study it can be concluded that the dietary inclusion of 40% DC can be used effectively in aqua feed formulation without compromising the growth of C. batrachus.
