2. Epidemic: mainly occurs in the larval stage of crabs.
3. Symptoms: Diseased crabs often appear unconscious, emaciated, and even die of severe illness. There is a large number of blood clots in the dead crabs.
4. Control methods: When catching and transporting crab seedlings, avoid damage. Add 4 to 5 grams of fish disease and other drugs per kilogram of feed every half a month, and then take 3 days for prevention.
Prevention must be thoroughly cleared before the stocking of crabs. Chemical, physical, or biological methods can be used to improve water quality. Photosynthetic bacteria can be used in breeding ponds and ponds to control the environment, and the density of river crabs should be appropriately reduced, and as much as possible avoided.
