This document discusses the benefits of integrated fish and poultry farming. The system creates a mutually beneficial relationship where poultry provide fertilizer for fish ponds through their manure, and the fish consume food waste from the poultry, reducing costs. This integrated approach increases productivity and profit per unit area by optimizing resource use. While fish growth may not be maximized, targeted feeding can address this issue. The document recommends polyculture of different fish species for better utilization of pond resources compared to monoculture.
