Abstract: This study presents a comparative analysis of the Feed Conversion Ratio (FCR) in Indian major carps, specifically Rohu (Labeo rohita) and Catla (Catla catla), under traditional and formulated feeding regimens. Conducted in the West Godavari district of Andhra Pradesh, India, the research involved nine ponds, each spanning 10 acres. Before stocking, optimal pond preparation techniques were utilized, including the application of quick lime, cattle dung, poultry manure, urea, and superphosphate. Fingerlings were introduced at densities of 2500 Rohu (200 grams) and 250 Catla (300 grams) per acre. The study employed various feeding regimes: De-oiled Rice Bran (DORB), Groundnut Oil Cake (GNOC), Cottonseed Cake (CSC), commercial sinking feed, and commercial floating feed, both containing 22% protein and 5% fat. The analysis focused on the FCR of traditional feeding methods compared to commercial feeding strategies. Key metrics evaluated included the average cost of fish production per kilogram and the total protein requirement for producing one kilogram of fish. Results indicated significant variations in FCR and cost-efficiency between traditional and commercial feeding regimens, providing valuable insights for optimizing feeding practices in aquaculture to enhance production efficiency and profitability.
