Common diseases and control methods of bullfrog

Bullfrog is the frog we often eat, it is large, delicate meat, rich nutrition, loved by consumers, its breeding range and density are also significantly improved, but followed by disease. So what diseases are there in bullfrog breeding, and how to control these diseases? come to the pro-farm network to take a look at the common diseases of bullfrogs to control them.

1. Bubble disease

Bubble disease mainly occurs in the tadpole stage, the whole body of the sick tadpole is swollen and swollen, causing it to lose its balance and float on the surface. If the sick tadpole is removed and dissected, it will be found that the intestines and stomach are filled with gas. The disease mainly occurs in the high temperature season, the organic matter content in the culture pond is too high, after high temperature fermentation, resulting in high nitrogen and oxygen content in the water, leading to the disease.

Prevention and control methods: usually strengthen water quality management, frequently change water, water injection, once the disease is found, immediately inject water, find ways to drop the temperature down, strengthen aeration, and then fish out the diseased tadpoles, put them into cooler water, and sprinkle them with magnesium sulfate solution.

2. Gastroenteritis

Gastroenteritis is also a common disease that harms bullfrogs, mainly in tadpoles and young frogs, which is caused by bacterial infection or indigestion. Its onset speed is extremely fast, the mortality rate is high, the stomach of the tadpole is inflamed and congested, and the anus is red and swollen, while the young frog or adult frog is characterized by sore and weak body, unable to beat, and serious death.

Prevention and control methods: the same to strengthen water quality management, do a good job of disinfection, feeding should pay attention to the freshness of feed, do not feed rotten and deteriorated feed. The residual bait is cleared in time every day, fresh bait is fed, and the disease can be prevented by soaking in salt water with lower concentration.

3. Hepatitis

It is extremely difficult to find when hepatitis occurs, and there are no obvious features in the appearance of bullfrog. the only appearance feature is that the body color loses luster, the color is gray and black, must be sick, bullfrog has a poor appetite or stops eating, lurking in dark and damp places in the grass, limp and limp, the mouth contains blood, and the tongue often spits out.

Prevention and control methods: the breeding ponds should be fully disinfected before stocking, especially in the old breeding grounds, strengthen water quality management, change water regularly, and forbid feeding spoiled bait.

4. Skin rot

Bullfrog skin rot is mainly caused by lack of nutrition, especially lack of vitamins or skin damage resulting in bacterial infection. When the disease occurs, the bullfrog skin loses its luster and appears white spots. With the development of the disease, the skin begins to fall off and rot, exposing the muscle tissue of the back, and in severe cases, it spreads the whole body. At the same time, black granular protuberances appear in the eyes, preferably leading to loss of vision.

Prevention and treatment methods: change water regularly, strengthen water quality management, often disinfect, strengthen nutrition allocation, and mix vitamins and nutrients in bait.

The above are the common diseases and control methods of bullfrogs brought by the pro-agricultural network. This is the end of the introduction on the diseases of bullfrogs. For more agricultural knowledge, please pay attention to the pro-agricultural network.
