Culture techniques: six key points in Loach culture

In recent years, due to the extensive use of pesticides and increased fishing intensity, the natural resources of Misgurnus anguillicaudatus decreased. Therefore, the artificial culture of Loach has been increasingly valued by the majority of farmers. As the waters of Loach culture are generally shallow and mostly still water, the water quality of culture is easy to deteriorate. Therefore, attention should be paid to scientific and rational feeding and fertilization in disease prevention and control, and the stocking density should be appropriate, and new water should be added frequently to keep the water quality fresh. To do a good job of disease prevention in Misgurnus anguillicaudatus culture is mainly to do the following six points:

1. Seedling quality

The seedlings of Loach with strong physique, strong vitality, smooth body surface, disease-free and injury-free should be selected.

2. Seedling disinfection

Before stocking, it is best to soak the seedlings with 2% murine and 3% salt water for 5-10 minutes to kill the pathogens on their body surface.

3. Stocking density

During the period of Misgurnus anguillicaudatus culture, if the stocking density is low, it will cause a waste of water resources, and the stocking density is too high, which can easily lead to Loach disease. Generally, there are 100-150 summer flowers per square meter with a body length of 3-4 cm, and 50-80 seedlings with a body length of more than 5 cm. Under good conditions, the stocking amount can be increased appropriately, otherwise the stocking amount should be reduced appropriately.

4. Feed management

Misgurnus anguillicaudatus is a kind of omnivorous freshwater economic fish, especially likes to eat silk earthworms, water fleas and other plankton, but animal feed should not be fed alone, otherwise it is easy to cause Misgurnus anguillicaudatus to be gluttonous, food indigestible, intestinal breathing abnormal, "flatulence" and death, and never feed spoilage feed, otherwise Loach is easy to suffer from enteritis and other diseases.

5. Water quality management

During the period of culture, good cultivation of water quality is an effective measure to reduce the culture cost, and at the same time, it meets the physiological and ecological requirements of Loach, which can make up for the shortcomings of incomplete nutrition and uneven feeding of artificial feed, reduce the occurrence of diseases and increase the yield. After stocking Misgurnus anguillicaudatus, topdressing should be applied timely according to the water quality in order to maintain a certain fertility of the water quality and keep the water body in a living and refreshing state.

6. Breeding environment

The breeding environment of Misgurnus anguillicaudatus should be in the place of shelter from the wind and sun and close to the water source. Misgurnus anguillicaudatus has low requirements for water quality, but the waters polluted by pesticides or too high concentration of chemical drugs can not be used as aquaculture water. Before stocking, the pond should be thoroughly disinfected and cleaned, and some aquatic plants should be planted in the pond to provide a comfortable, shaded and quiet living environment for Loach. At the same time, the roots of aquatic plants also provide a place for the reproduction of some benthos and provide natural bait for Loach.
