Yellow eel is a freshwater fish that is widely distributed in rivers, lakes, reservoirs and other waters throughout China. The yellow eel has delicate flesh, delicious taste, rich nutrition, and has certain medicinal value. Therefore, yellow eel farming has high economic and social benefits.
1. Food of yellow eel**.
Yellow eel mainly eats meat and is a fish with a relatively mixed diet. In the natural environment, the food of yellow eels** mainly includes plankton, small crustaceans, insects, insect larvae, oligochaetes, etc. In addition, eels feed on mud-bottomed snails and other small invertebrates.
Under artificial breeding conditions, the food of yellow eel mainly includes earthworms, fly maggots, small fish, small shrimp, etc. In addition, yellow eels also eat some plant foods such as vegetables and fruits.
Second, the breeding method of yellow eel.
Breeding environment. Yellow eel farming needs to choose a place with fresh water quality, pollution-free water source, suitable water depth, sufficient sunlight and quiet environment. At the same time, it is necessary to build a good breeding pond, keep the pond water clean, and change the water regularly.
Breeding density. The breeding density of yellow eel needs to be determined according to the size, physical condition, water quality conditions and other factors of yellow eel. In general, 10-20 eels can be reared per square meter.
Feed feeding. Yellow eels need to be fed regularly, generally 2-3 times a day. The feed can choose earthworms, fly maggots, small fish, small shrimp, etc., and you can also choose some compound feed. The amount of feeding needs to be determined according to the size of the eel, feeding and other factors.
Disease prevention and control. Yellow eel is prone to disease in the breeding process, and it is necessary to do a good job in disease prevention and control. Generally, it is necessary to disinfect the breeding pond regularly to keep the water clean. At the same time, it is necessary to regularly check the physical condition of the yellow eel to detect and develop diseases in time.
3. Tips for yellow eel farming.
Adjust the water level appropriately.
During the breeding process, the water level can be adjusted appropriately to adapt to the changes in different seasons and weather conditions. In general, the water level needs to be deepened in summer to keep the water temperature stable; In winter, the water level needs to be lowered to reduce the impact of ice on the eel.
Adjust the lighting appropriately.
Light has a certain effect on the growth and reproduction of yellow eels. In the process of breeding, the light intensity and time can be appropriately adjusted to promote the growth and reproduction of yellow eel.
Reasonable mix of feed.
When feeding the feed, different kinds of feed can be reasonably matched to meet the nutritional needs of the yellow eel. At the same time, it is necessary to pay attention to controlling the amount of feeding to avoid the deterioration of water quality caused by overfeeding.
Take precautions to prevent escape.
In the process of breeding, it is necessary to take anti-escape measures to prevent the yellow eel from escaping or being preyed upon by other animals. Anti-escape nets, anti-escape walls and other facilities can be set up to ensure the safety of yellow eels.
In short, yellow eel farming requires mastery of certain techniques and management methods, as well as attention to detail and skill. Only by doing a good job in every link can we improve the efficiency of breeding and product quality.
