1. Pond selection
When cultivating snakeheaded fish, you must first determine the breeding area of ??the pond. It is not suitable to breed too many snakeheaded fish, but it can be divided into several ponds and raised separately. About 2-5 acres. The water depth is about 2 meters, and there should not be too much silt at the bottom of the pond. Anti-escape nets must be installed at the water inlet and outlet of the pond to prevent snakeheaded fish from escaping during the breeding process. Before stocking, you need to splash quicklime on the fish pond to disinfect it. You can also plant water lilies about one meter wide in the pond. This will not only prevent snakeheaded fish from jumping out of the pond, but also effectively shade the pond. The pond should be located away from noisy places, with sufficient clean and hygienic water sources, and a good drainage and water exchange system.
2. Fish species release
When choosing fish species, you usually buy them in the market. Although the prices in the market are relatively low, their specifications are different, and in many cases Can cause mechanical damage to fish. Therefore, before stocking fish fry, the pond must be disinfected with quicklime, or the fry must be soaked in salt water and bleach for about 20 minutes to disinfect the fish fry. The stocking density of snakehead fish is determined based on various factors such as breeding area, feeding technology and feed. Generally, up to 2,500 snakehead fish can be cultured in one acre.
3. Feeding
Anyone who has experience in snakehead farming knows that snakehead is a very ferocious carnivorous fish, whether it is live or dead meat. They mainly feed on various small fish and shrimps in the pond. When artificially feeding snakeheaded fish, they must be fed at fixed points and times every day, at least twice a day at 10 a.m. and 3 p.m. Generally, after a week of stocking, the fish species will start to compete for food on the water surface. When the snakeheaded fish are eating, you should also carefully observe the eating situation of the snakeheaded fish. If there are fewer snakeheaded fish near the food or the competition between the snakeheaded fish is not intense, time, it means that most of the snakeheaded fish are full and can stop feeding.
4. Feeding and management
The snakehead fish has a very large feeding habit, so it also produces a lot of excrement, so the water in the pond will soon become fatter and fatter, resulting in A large number of zooplankton breed and breed. Causes hypoxia in the pond, so when breeding, you must pay attention to changes in the amount of dissolved oxygen in the water. If hypoxia occurs, oxygen must be added in time. If the situation is serious, surface sterilization must be adopted. Now, sprinkle trichlorfon on the edge of the pond about 3 meters away. Although snakeheaded fish has strong disease resistance and has a low incidence rate during breeding, snakeheaded fish will still get sick if not properly managed in autumn, so everyone must always pay attention to the growth of snakeheaded fish at this time. If abnormal situations are discovered, corresponding measures must be taken promptly.
