Loach diseases focus on prevention, how to do a good job of disease prevention

Because the water depth of the cultured Loach is shallow, and most of them are still water, the water quality of the cultured Loach is easy to deteriorate. Therefore, in addition to scientific and rational feeding and fertilization, we should also pay attention to the appropriate stocking density, and often add new water to the waters of the cultured Loach to maintain fresh water quality. To do a good job in disease prevention of Loach culture, we should mainly do the following.

Loach

First, the breeding environment. Shelter from the wind and the sun, the place near the water source is more suitable for the breeding of Loach. Although Misgurnus anguillicaudatus has low requirements for water quality, the waters where the concentration of chemical drugs is too high or polluted by pesticides can not be used to cultivate Loach. Before stocking, the pond should be thoroughly cleaned and disinfected, and some aquatic plants should be planted in the pond, so that Loach can have a shaded, comfortable and quiet living environment. At the same time, the roots of aquatic plants are also breeding places for benthos that can provide natural bait for Loach.

Second, the quality of seedlings. It is necessary to choose Loach seedlings with no disease, no injury, strong physique, strong vitality and smooth body surface.

Third, seedling disinfection. Misgurnus anguillicaudatus seedlings before stocking, it is best to soak in 2%-3% salt water for 5 to 10 minutes to kill the pathogens on their body surface.

Fourth, stocking density. During the cultivation of Loach, if the stocking density is low, water resources will be wasted; if the stocking density is too high, Misgurnus anguillicaudatus is prone to disease. In general, the seedlings with body length 3cm~4cm are 100 ~ 150 / m ~ 2, and those with body length above 5cm can be 50 ~ 80 / m ~ 2. The stocking amount can be increased appropriately if the conditions permit, otherwise the stocking amount of Loach should be reduced properly.

Fifth, feed management. Misgurnus anguillicaudatus is omnivorous fish, especially likes to eat silk earthworms, water fleas and other plankton, but generally should not be fed animal feed alone, because it will cause Loach gluttony, indigestion, abnormal breathing, "flatulence" and death, never feed spoilage feed, otherwise Loach is prone to enteritis and other diseases.

6. Water quality management. During the culture period, the effective measure to reduce the culture cost is to grasp the water quality culture, and the water quality culture also meets the physiological and ecological requirements of Misgurnus anguillicaudatus, which can make up for the shortcomings of incomplete nutrition of artificial feed and uneven feeding of Misgurnus anguillicaudatus. It can also reduce the occurrence of Loach diseases and increase yield. After stocking Misgurnus anguillicaudatus, topdressing should be applied timely according to the water quality in order to maintain the fertility of the water quality. The water body should always be kept alive and refreshed.
