Can snakeheads be farmed?
Yes

Currently, most of the snakeheads on the market are caught in natural waters, and the proportion of artificial culture is still relatively low. Artificial culture of Channa striata is also based on mixed culture in ponds, subject to the artificial propagation technology is not mature, the seedlings are collected in the field, as a "supporting fish" and other cultured species are mixed in the same pond, the scale of culture is small, the specification of the fish, the yield is difficult to ensure.

Before the release of seedlings, the pond should be drained. After dredging, exposure to the bottom of the pond dry cracks, exposure to 100 to 150 kg of lime per mu or with bleach 5 to 10 kg disinfection to kill pathogenic bacteria, wild fish and hostile organisms. 3 to 5 days, in the bottom of the pond to lay tile tube, tile, large diameter bamboo tube, scrapped large tires or grey plastic tubes as a habitat hiding, and then filtered into the water with a 40 mesh mesh net, the water depth of 60 to 80 cm, and the application of ammonium carbonate 0.5 ~ 1 kg / mu and calcium superphosphate 0.05 ~ 0.1 kg / mu fertilizer, 3 ~ 5 days can be released fry. Before entering the pool, the fish can be 5 × 10-6 concentration of potassium permanganate solution bath for about 5 minutes. Putting should be carefully from the edge of the pool does not leave the water to put fish into the pool, for the vitality of the weak, dead and injured fish species should be fished up in a timely manner. Fish stocking density should be based on the specific circumstances of the breeding.

Sandpiper snakehead adult fish can be mixed or mono-culture, especially mixed for good. Sandpiper feeding pond can be planted some aquatic plants, for its habitat hidden, but also to improve water quality. Mixed farming can not only let the snakeheads prey on the wild fish in the pool, but also increase the stocking varieties and production, which is conducive to improving the economic benefits of aquaculture.

Generally in the culture of river crabs, prawns and four big fish in the pond mixed culture of snakeheads, per mu stocking body length of 2 cm snakeheads summer flower fish fry 1000 ~ 1500, can be used in the pond of wild fish, shrimp as bait, per mu can catch snakehead commercial fish 50 ~ 75 kg. Such as the use of small ponds to raise the main sand snakehead, 2500 ~ 3,000 fish species per mu, feeding 7 ~ 8 months, mu yield can reach 120 ~ 150 kg or so. Fish species of different sizes should be cultured in separate ponds according to large, medium and small to avoid the phenomenon of cannibalism. In the case of insufficient bait in the late feeding period, wild miscellaneous fish fry and egg-holding green shrimp can be put in the pond to let them reproduce naturally in the pond, so as to continuously supply bait to the sand snakeheads.
