Koi and herring polyculture increase efficiency
In order to fully tap the potential of the water body, adult fish farming is mostly polyculture, dense-growing and rotation. If the squid is polycultured with herring in the same pool, it is easy and fast to grow. The commonly used ratio is 1 kg of herring species for each stocking, and 2 to 4 tails of squid with a total length of about 13 cm are stocked. For example, with grass carp polyculture in the same pool, each kilogram of grass carp stocks is stocked with only one carp weighing 50 to 100 grams. In the well-preserved fish ponds where fish are kept in close range, rapid growth of the fish to obtain sufficient food is necessary to fertilize natural foods and feed artificial diets. First, the general principle of fertilization is to achieve water quality and maintain the "fat, live, tender, cool." Third, daily management to achieve "six four": 1, four early morning: Early clear the fish pond, early release of fish species, early feeding and early feeding bait pond. 2, four to see: see the fish's activities, see the changes in water quality, see the weather, see the season. 3. Siqin: Observe the grounds and observe the growth and health of the fish. Diligently clean up the fish pond and prevent diseases. 4, four defenses: prevent floating head, pan pool, fish disease prevention, disaster prevention, security. 5, four set: feeding, qualitative, quantitative, timing, positioning. 6, four elimination: fingerling disinfection, food disinfection, tool disinfection, regular disinfection of the food court.

Second, the general principle of feeding is "uniform, sufficient, and good." If the feed is fully fed, the daily feed amount can be calculated as 1 to 5% of the fish's increasing body weight.
