Determination of proximate composition of native catfish (Mystus cavasius) fed with poultry offal’s protein rich formulated feed in captive condition

The experiment was conducted to evaluate the effects of poultry offal feed on the body composition of Gulsha fish (Mystus cavasius) using four treatments and three replications for 60 days.Using AOAC method, dry matter (DM), moisture, crude protein (CP), crude fat (CF), and total ash were measured during experimental trial in a laboratory setting to assess the changes of proximate composition of Gulsha fish fed on four different poultry offal formulated feeds viz., Diet-1 (30% FM+0% POM); Diet-2 (20% FM+10 POM); Diet-3 (10% FM+20 POM), and Diet-4 (0% FM+30% POM).In dry matter basis, mean value of dry matter, moisture, crude protein, total ash and crude fat of fingerlings Gulsha were found to be 24.7%,75.3%,63.27%, 10.6%, and 10.56%, respectively.After culturing with different formulated diets, the mean value of dry matter, moisture, crude protein, total ash and crude fat were found to be diet1 (23.53%, 76.47%, 67.22%, 10.58%, 12.09%), diet2 (22.63%, 77.37%, 71.17%, 10.16%, 12.38), diet3 (22.97%, 77.03%, 68.17%, 10.1%, 11.30%), and diet4 (23.02%, 76.97%, 65.32%, 10.24%,11.18&),respectively.The study found significant variation in proximate composition between fingerling Gulsha and cultured with formulated diets.Diet-2 had the highest protein content (71.17%), moisture content (77.37%), and fat content (higher in diet-2 compared to fingerling).The result suggests that feeding Gulsha with protein-rich poultry offal formulated fish feed as an alternative to fishmeal.
