Formation and prevention of flatulence disease in cultured Misgurnus anguillicaudatus

After the overwintering period, the physique of Loach is weak, the whole overwintering period is in the fasting stage, the intestinal wall of Loach is relatively thin, coupled with a long time without peristalsis, the digestive ability is still very weak. Therefore, even if the farmers do not feed in large quantities, it is also prone to the phenomenon of flatulence. After the overwintering period, the water quality in the Loach pond is thicker, there are more organic matter and impurities in the water, and some pond water feels sticky or astringent, so the gas content in the water body is often on the high side, which is easy to cause "flatulence" of the Loach, that is, the intestinal tract of the Loach is full of small bubbles, which increases the buoyancy of the Loach. Therefore, the smaller Loach will lie on its side on the surface of the water. Misgurnus anguillicaudatus living in this body of water, the gas in the water accompanied by the feed into the intestinal tract, which is why the small amount of feed is also easy to flatulence. Air bubble disease is easy to occur if the water condition is too poor.

Loach eating causes flatulence, from the outside, Loach's belly is round, belly lying up in the water, you can see that the belly is black and white, black is the feed; cut open the Loach intestines, you can see the feed row in the Loach intestines, a little effort, that is, overflow from the anus. Many farmers disapprove of this, but the occurrence of a large number of flatulence will cause the outbreak of Loach enteritis, so it is necessary to prevent the occurrence of Loach enteritis in advance. Prevention and control methods (1) change the water regularly, keep the water fresh, change the water in time when the water quality is sticky or astringent; (2) improve the sediment regularly, control the discharge of gas from the sediment, and reduce the content of gas in the water body; (3) the amount of food should be less in the early stage, not more, and gradually increase the amount of feed, and reduce the amount of feed on cloudy and rainy days.
