Snakehead is a fierce carnivorous fish. It likes to inhabit lakes, reservoirs, rivers, ditches and ponds, with lush water plants and soft mud. It usually lurks at the bottom of the water and swims to the upper and middle layers of the water when it is foraging or lacking oxygen. Snakehead has a strong adaptability to bad water quality, water temperature and hypoxia. Usually I like to hide in water and grass, waiting for opportunities to prey on small animals such as small fish, shrimp, frogs and mice. The larger snakehead can swallow large birds such as ducks, especially during the protection of young, and the snakehead has a bad temper.
The survival water temperature of snakehead is 0 ~ 38℃, and the optimum water temperature is 16 ~ 30℃. When the water temperature rises above 8℃ in spring, snakehead often moves in the middle and upper water. When the water temperature drops below 6℃ in autumn, it swims slowly and often lurks in deep water. When the water temperature is too low in winter, they hibernate underwater. The snakehead is a carnivorous fish, and its food varies with the size of the fish. Young fish below 3 cm mainly feed on cladocera, cladocera and chironomid larvae. Small fish with a body length of 3~8 cm mainly feed on larvae, maggots, small fish, shrimps and tadpoles in aquatic insects. Adult fish over 20 cm mainly eat wild miscellaneous small fish, shrimp, frogs and other carnivores.
The magical nature will always subvert people's cognition and bring unexpected surprises inadvertently. We should thank the fisherman, otherwise we never thought the mullet would grow so big. As long as someone catches a big fish, there will be a lot of calls for release on the Internet. They are distributed in many natural waters in China, and the fish caught by fishermen is not enough to have any impact on them. ?
