Key techniques of mixed culture of snakehead

Mixed-culture snakehead is a collocation breed. Take advantage of snakehead's love for fish to eliminate wild fish in the pond and turn harm into benefit. Therefore, the size of snakehead is smaller than that of economic fish cultured in ponds, and cannot be equal to or greater than 1/3 of other economic fish cultured in ponds, otherwise it will be eaten by snakehead. Even the same species of snakehead varies greatly in appearance and size, and there is also gluttony. Snakehead is not resistant to high temperature, and likes to hide in the grass to catch passing fish. Therefore, after a long summer, floating plants such as water hyacinth should be planted in the pool, which should account for about one tenth of the area and should not be too much. In summer flowering period, the activity of snakehead is weak, so it is not allowed to leave aquatic plants in the culture pond, because aquatic plants often trap fry, which affects their feeding, hinders their growth, weakens or is too small, but is eaten by peers or kills each other, suffering from diseases such as water mold.

The bait should be fresh, rotten fish can't be fed, sometimes it will be discarded by snakehead fish, and sometimes it will cause fish to get sick. In order to ensure enough small bait, we can fertilize regularly, keep the transparency at 25 cm, cultivate plankton, promote the growth of wild fish as soon as possible, and promote its multiple reproduction.

The bigger the snakehead, the more bait it needs, and the lower the return on output value. Therefore, when snakehead meets the market standard, it should be caught and sold as soon as possible. Grasp the big and stay small, and grasp the big and make up for the small. The polyculture amount is about 15 fish per 667 square meters of water surface according to the crude output of wild miscellaneous fish. You can put more snakeheads in ponds rich in wild fish.

The most common diseases of snakehead are rot and white skin disease. The cause of disease is killing each other and causing bacterial infection. It's hard to get sick without injury. The reason for killing each other is that the bait is insufficient, and the fish are killed or injured.

Sufficient bait grows fast, but insufficient bait fights; If you don't die, you will get sick, which is often favored by white slime molds. The main fish pond plays an auxiliary role and contributes a lot to swallowing miscellaneous fish; Eliminate bait-consuming and oxygen-consuming miscellaneous fish and reduce fish diseases.
