The control technology of enteritis, a common disease in tilapia farming
1. Symptoms of Tilapia Enteritis Sick fish usually have black body, slow movement, stray swimming alone, swollen abdomen and erythema. In severe cases, light pressure on the abdomen will cause bloody yellow mucus to flow out. Sometimes the diseased fish will not move at the edge of the fish pond for a short time. Internal convulsions to death.

2. Causes of Enteritis in Tilapia
The pathogen causing tilapia enteritis is intestinal Aeromonas punctata, which is a conditional pathogen. Such bacteria exist in the intestinal tract during the entire process of tilapia farming. In healthy fish, this strain is not dominant and does not cause disease. However, when the water quality environment deteriorates, the dissolved oxygen decreases, the feeding of spoiled feed, and the feeding of the bait is not fixed or quantitative, that is, when the water is full, hungry or overeating, the resistance of the fish body will decrease, which will cause Luo Fei The occurrence of fish enteritis. Therefore, enteritis may occur during the entire breeding cycle, which is very harmful to tilapia.

3. Prevention measures
1. In the process of tilapia breeding, it is recommended to feed it regularly with green feed, which has a certain effect on the prevention of enteritis. The main reason is that the cellulose and vitamins in green feed can promote the secretion and increase of intestinal digestive juice. The role of animal immunity.
2. Whether enteritis occurs is inseparable from the ratio of harmful bacteria to beneficial bacteria in the intestine. To avoid enteritis, it is necessary to supplement beneficial bacteria such as lactic acid bacteria. Use Lechang to inhibit the content of harmful bacteria, so that beneficial bacteria can take advantage, thereby reducing the risk of enteritis. Morbidity.
3. Control the breeding density and reduce the occurrence of stress. At the same time, feeding Eucommia ulmoides leaf extract-Fortune 100, can enhance the body fitness and immunity of tilapia, anti-bacterial and anti-virus, enhance the anti-stress ability of fish, and reduce bacteria infection.
