A Detailed Explanation of the Key Management Points in Snakehead Fish Farming
The snakehead fish is also called the snakehead, snakehead fish and so on. Because of its rich nutritional value and rather high economic value, it is widely farmed artificially. So, what are the management points in snakehead fish farming? Let's find out together!
1. Pond management
The pond for snakehead fish farming should be chosen in a sunny spot, and the water level in the pond is generally 1 m to 1.5 m deep. Some aquatic plants should be planted appropriately around the pond, and at the lower parts of the pond, netting should be used to enclose it. Before stocking, we should thoroughly disinfect the pond, and then appropriately spread in some base fertilizer to cultivate the water body. Later, we should also clear the pond at irregular intervals to ensure a good farming environment.
2. Fry stocking
For snakehead fish fry, we generally have to purchase from formal, disease-free areas. 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, when the fry are about 3 to 5 cm, then 8,000 to 9,000 can be stocked per mu, while for a size of about 10 to 15 cm, only about 5,000 can be stocked per mu. Finally, for fry of about 20 cm, at most only 2,000 can be stocked per mu. In addition, in later rearing, they should also be continuously grouped and reared separately, so as to ensure the yield and quality of the snakehead fish.
3. Feed feeding
The feed should be of good quality and low price, produced by formal units, and one should not seek cheapness and choose inferior products. The feed mainly includes crude protein, crude fiber, fish meal, 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 a balanced nutrition for the snakehead fish. At the same time, the feeding of bait should be done at fixed times, fixed locations, fixed quality and fixed quantity. Generally, the best feeding times are from 8 to 9 o'clock every day and from 4 to 5 o'clock in the afternoon. Under normal conditions, feeding is done 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 technology. 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. Also, we should always pay attention to weather changes, and observe the snakehead fish's daily movement, feeding and other conditions, and prevent diseases in time. Finally, we should do a good job in preventing escape, so as to avoid unnecessary losses.
