Clever use of the complementarity between various fish life habits, appropriate breeding of some beneficial varieties in the main cultivar, to achieve the purpose of regulating water quality, preventing and controlling diseases, and fish rearing. For ease of operation, a brief introduction to the life characteristics of common fish is now available for reference when selecting. First, carp, carp They are the bottom of the "cleaners", which inhabits the bottom of the water, feeding the bottom of the bait and humus, make full use of residual organic matter in the water, can greatly reduce the decomposition of organic matter in the bottom of the decomposition, reduce the occurrence of fish disease . Second, the three kinds of fish, squid, black scorpion, and California scorpion are regarded as the "mistaging pioneers" in the water body. They have fierce temperament and can ingest large amounts of wild fish and shrimp. One of the three types of fertilization can be used to control the growth and reproduction of wild fish and shrimp, reduce competition pressure with the main fish to compete for oxygen, and use natural animal feed to increase fish production. Fresh fish and shrimp are used in the major water bodies such as squid and black quail, while corpses and viscera are also used to remove water pollution. Third, the white peony is known as the “water filterâ€. The proper culturing of the peony can make full use of the natural bait resources such as plankton in the water, control the water body fatness, and thus adjust the water quality. At the same time, the sea bream is also a "forecaster" of the fish's hypoxic floating head. When the white locust appears floating head, it indicates that the water body has begun to lack oxygen, and oxygenation measures should be taken in time. 4. The three types of grass carp, catfish, and crustacean are called “hygiene staffs†in the water. In cases where there are too many aquatic plants in the water or there are many weeds on the shore, grass carp, carp, and head pups can be properly reared. It can both purify the breeding environment and use natural foods to increase the fish yield. The head fish also eat grass and fish leftovers. The carp also likes algae in the water. 5. Herring often inhabits the lower layers of the body of water, carnivorous, feeding on insect larvae, snails, mussels, etc., and snails, oysters, clams, shrimps and other more water can be set appropriately to raise herring. 6. Tilapia has a large role in water bodies. It eats aquatic plants as well as various organic detritus, algae and aquatic insects. It not only makes full use of water resources, but also regulates water quality. Tilapia often digs in the bottom of water to improve the quality of the bottom. At the same time, Tilapia prefer to eat fish in the water, anchor head and other fish, can reduce the risk of fish diseases. In addition, tilapia is easily frightened, and its back and forth swimming in the water can prevent water rats from stealing fish. 7. Red snapper, red snapper, and red snap are called "indicator fish." In cage culture, if you want to check whether the cage is damaged, you can stock dozens of red snapper, red snapper, and red roti. If the number of such fish is reduced, it means that the cage has been damaged and needs to be repaired to reduce unnecessary loss. In addition, these fish, with their bright red color and fast swimming speed, can prevent water-eating mice and otters from stealing fish. (Bao Hao)
