1. The ratio of grass carp and other phagocytic fish to filter-feeding and omnivorous fish in mixed culture has been studied and practiced for a long time. It has been proved that if the main phagocytic fish are fully fed and any pond mud and residual feed are excluded to provide nutrition, the ability of phagocytic fish to feed filter-feeding fish is 15% of their weight, that is, the weight ratio of phagocytic fish to filter-feeding fish in mixed culture is 100:15; 2. The ratio with omnivorous fish is 100:10. If there is pond mud and leftover feed, the two ratios are 100:20 and 100:15 respectively.
