Supplementation of Four Protein Percentage to the Basal Diet of Catfish (Mystus cavasius) Fingerlings: To Analyses the Optimum Level of Protein and Body Composition of Fish

Reducing feed cost and the pollution originating from feed have been principal matters in fish nutrition. Mixed feeding schedules have been proposed as one of the methods to reduce both of them and successfully tested in many fish species. The aim of the present study was to determine the mixed feeds containing 30, 35, 40 and 45% of protein content of four pelleted feeds was given to the four groups of cat fish (Mystus cavasius) and evaluating the optimum level of protein in the diet for this fish by studying the biochemical parameters of cat fish (Mystus cavasius) 60 days feeding schedules.
