Technical Points and Methods for Snakehead Fish Farming Explained
Strictly speaking, snakehead fish refers to the northern snakehead, also called snakehead. It is a rather fierce fish with extremely strong reproductive capacity, but in our country it is a very common food fish. It has few bones and few intermuscular spines, and its flesh is tender with high nutritional value. Eating snakehead fish helps wound healing and also has a nourishing and restorative effect. There are also many large-scale snakehead fish farms in our country, but how exactly do you farm snakehead fish? Today, the editor will focus on explaining the key points of snakehead fish farming. Friends who need it can read carefully.
1. Pond Management
The pond for snakehead fish farming should be chosen in a sunny location, and the water level in the pond is generally about one meter to one and a half meters deep. Some aquatic plants should be properly planted around the pond, and the lower areas of the pond need to be enclosed with netting. Before stocking, we must thoroughly disinfect the pond, and then properly spread some base fertilizer to cultivate the water body. Later, we should also clean the pond at irregular intervals to ensure the farming environment.
2. Fry Stocking
We generally purchase snakehead fish fry from regular areas free of disease. The purchased fry also need to be disinfected first with salt water, generally for about five minutes. Density management during stocking is also very important. The stocking density of fry is mainly related to the size of the fry. Generally, if the fry are about three to five cm, then 8,000 to 9,000 can be stocked per mu, while if the size is about ten to fifteen cm, then only about 5,000 can be stocked per mu, and finally for fry about twenty cm, at most only 2,000 can be stocked per mu. In addition, in later rearing, they must also be continuously grouped and raised separately, so as to ensure the yield and quality of the snakehead fish.
3. Feed Feeding
The feed should be chosen from regular producers offering good quality at a low price; do not seek cheapness and choose inferior products. The feed mainly includes crude protein, crude fiber, fishmeal, bone meal, soybean, flour and other nutrients. While feeding with feed, it is also necessary to supplementarily feed some bait such as river mussel meat and small fish, so as to ensure balanced nutrition for the snakehead fish. At the same time, bait feeding should be done at fixed times, fixed locations, with fixed quality and fixed quantity. Generally, the best feeding times are from eight to nine o'clock every day, and from four to five o'clock in the afternoon. Normally, they are fed twice a day. If the weather is bad, then basically only one feeding a day is needed.
4. Daily Management
Daily management is also a key point in snakehead fish farming techniques. After feed feeding, we should promptly scoop out the remaining food residue, and disinfect the pond at irregular intervals, generally about once every half a month. At the same time, we should check the water quality in the pond and change the water at irregular intervals. In addition, we should always pay attention to weather changes and observe the daily movement, feeding and other conditions of the snakehead fish, so as to prevent diseases in time. Finally, we must do a good job of preventing escape to avoid losses.
The above are the technical key points of snakehead fish farming. Basically, once you master these key points, there will not be any major problems in farming snakehead fish. If there is anything else you want to know, you can follow us, or contact the editor directly.
