The culture density of snakehead is relatively high, with a pure area of 660m2 per mu of water surface, and 1 10,000 fry can be put in fish ponds. The snakehead grows rapidly, ranging from 1. 1 kg to 3kg. The snakehead has strong vitality, and it will be laid flat in the fish pond when it is released. When it is fed with the feed of snakehead, it will not pollute the water source and affect the growth of snakehead.

Special culture technology of snakehead

Generally, there are two sources of fish species, one is wild and the other is artificial breeding. However, no matter which species come from, they should be screened before going into the pond. The species with basically the same specifications should be bathed in 3% ~ 5% salt water for 5 ~10 minutes, and then put into the same fish pond. The stocking density depends on the water source, water injection and drainage conditions, the source of bait fish, etc. In general, 6,000 ~10,000 fish are stocked in 667 square meters for 3 ~ 5 cm long fish. 10 ~15 cm long fish, stocking 4000 ~ 6000 fish; About 2000 fish species of about 20 cm are stocked. If the water source, water injection and drainage conditions are good and the source of bait fish is sufficient, the stocking density can be appropriately increased.
