Effect of citric acid supplementation on growth parameters of Cirrhinus mrigala fingerlings fed canola meal based test diets
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2016, Vol 9, Issue 1
Abstract
Increasing demand with high price and unstable supply of the fish meal with the expansion of aquaculture made it necessary to search alternative protein sources. Due to higher pH of digestive tract, fish cannot absorb nutrients. Use of citric acid is beneficial for the absorption of nutrients by decreasing pH of digestive tract. Therefore, the aim of the current study was to explore the effect of citric acid supplementation on growth performance of Cirrhinus mrigala fingerlings fed canola meal based test diets. Six experimental test diets were formulated by supplementing with graded levels (0%, 1%, 2%, 3%, 4% and 5%) of citric acid. Fingerlings in triplicate tanks were fed at the rate of 5% of live wet weight. Fifteen Cirrhinus mrigala fingerlings were stocked in V-shaped tanks with the capacity of 70 liter water twice daily, for ten weeks in feeding trial. Feces from each tank were collected twice a day and were dried at 60°C and grinded for analysis. The result showed that Cirrhinus mrigala fingerlings fed canola meal based diet with 3% citric acid indicated significant improvements (p<0.05) in weight gain (352.65%), SGR (1.68%) and minimum FCR (1.21). From the results, it was concluded that 3% citric acid supplementation in canola meal based diet is the optimum level for growth performance in Cirrhinus mrigala fingerlings.
