1. Site selection and construction of fish pond: It is best to choose the fish pond for raising snakehead in the sunny position with a water depth of about1-1.5m. Aquatic plants can be planted around the fish pond. Disinfection should be done well before stocking black fry to avoid infection with germs and losses.

2. Stocking black fry: It is very important to buy black fry from regular channels, which can increase the survival rate. The bought fry should also be disinfected, usually with salt water, not for too long, about five minutes.

3. Scientific feeding: snakehead has a large food intake and a wide range of foods suitable for it, such as clam meat, small fish, shrimp, soybeans, fish meal and flour. Usually, we should pay attention to its scientific feeding and help it grow.

Growth habit

It has strong adaptability to the changes of environmental factors in water, especially to hypoxia, poor water temperature and water quality. When the water is short of oxygen, it can stick its head out of the water. The back side is flat. The head is long, slightly flat at the front and slightly higher at the back.

With the help of the suprabranchial device consisting of the upper branchial bone on the back of the first branchial arch and the bone fragments extending from the glossopharyngeal bone, oxygen in the air can be directly breathed. So it can survive for a long time even in humid areas with little water and no water.

The survival water temperature is 0-4 1℃, and the optimum water temperature is 16-30℃. When the water temperature reaches above 8℃ in spring, it often moves in the upper and middle layers of water. Active in the upper water body in summer; When the water temperature drops below 6℃ in autumn, it swims slowly and often lurks in the depths of water; When the water temperature approaches 0℃ in winter, it will stay in the mud and stop eating.
