Evaluations of Body Composition and Growth Performance by Applying Different Dietary Vitamin C Levels in Stinging Catfish, Heteropneustes Fossilis

An experiment was conducted for sixty days to evaluate the effects of Vitamin C of formulated feed on growth performance and body composition of stringing fish, Heteropneustes fossilis (Bloch, 1792). During experimental trial in the laboratory condition, the change in growth and feed utilization by the stringing fish fed on three different Vitamin C level have been assessed by the determination of condition factor (K), survival rate (SR), specific growth rate (SGR%), feed conversion ratio (FCR) and average daily gain (ADG) and protein efficiency ratio(PER). All the water quality parameters specificallyTemperature (°C), Dissolved oxygen (DO), Carbon dioxide (CO2) and pH in the plastic tanks were highly monitored and maintained. The highest food conversion ratio (FCR) was found in the treatment 1 while the lowest was measured in treatment 3. The values of protein efficiency ratio (PER), condition factor, average daily gain (ADG) and specific growth rate(SGR) were highest in treatment 3 and lowest in treatment 2 and treatment 1 respectively. Result of the current study showed that supplementation of Vitamin C at 1200 mg/kg feed had significant positive effects on the FCR, SGR, ADG, PER while no such differences were observed in condition factor variables. The fish Diet C containing 1200 mg/ kg of Vitamin C level has been found to be more effective for better growth of the stringing fish.
