The resistance of the eel is strong, and it is generally unacceptable for disease. However, if you do not have the law, you can also make you sick. The main diseases and control methods for fleas are described below:
First, green mold: also known as green moss disease, is the main disease of artificial breeding of earthworms. From mid-June to the end of August, due to high temperatures, high humidity, and mildew in food, maggots are susceptible to infection by pathogenic bacteria. The early stage of infection is mainly the appearance of small spots of black or green on the skin of the joints, and then gradually expand; then the body surface loses luster, black spots appear below the abdomen, loss of appetite, sluggish operation, and ultimately died of refusal to eat thin . The main cause of the disease is the excessive humidity in the feeding environment or the rot of the food in the pool.

Control methods: (1) Remove mildewed food, drive fresh live food, maintain good hygiene in the culture tank, and conduct disinfection and sterilization. (2) Adjust the temperature and humidity in the culture tank and keep it afloat. (3) for the onset of phlegm can be used penicillin 0.25 g water 1 kg spray disinfection or add water to drink. (4) A total of 0.6 grams of edible mothers, 0.25 grams of oxytetracycline, and 0.25 grams of chloramphenicol are powdered into a powder and mixed with 400 grams of feed until they are cured.

Second, the bloating disease: phlegm in the fall after the cold and cold period suffering from the disease, mostly due to more food and low temperature caused. In the early stages of the disease, the head was purple-red, the poisonous hooks were full, they did not eat or eat, the abdomen swelled, and the operation was delayed. The disease died after about 1 week of illness.

Control methods: (1) Mix 1 g of water and 500 g of water and let it suck and increase the temperature. (2) After adding 0.5 g of sulfaamide to finely ground, add 300 g of feed and mix well; use 0.25 g of chloramphenicol and 300 g of feed to mix well and feed it every other day until it is cured.

Third, shelling disease: As a result of a damp habitat habitat, so that the fungus caused by body parasites. The initial performance was restlessness, creeping back and forth, late performance as weakness, slow action, and eventually died of inaction.

Control methods: 0.25 grams of oxytetracycline, 0.6 grams of food mother, 1 gram of calcium, a total of research into fine and 400 grams of feed mix, and even feed for several days, until recovered.

Fourth, the ant damage: Insects or spawning eggs during the incubation period of the cricket resistance is weak, when the ants enter the group will attack and attack, resulting in the pupa when the fleas were killed, or the hatchlings of females abandoned eggs and fled.

Control methods: (1) Dig a ditch around the breeding pond and inject water to prevent ants from entering. (2) Fruits or other sweets can be used to induce ants with fruit or other sweet food and then stunned by ants and burned with boiling water.

5. Miscarriage: Pregnancy and convulsions are mostly caused by disturbances, tumbling, noisy or direct stimulation of foreign bodies. Therefore, during pregnancy, entertainment is kept quiet, and it cannot be turned frequently.
