How to prevent rice field eel diseases in spring? Garlic and salt solution works well
After overwintering, rice field eels begin to become active in spring when the temperature rises. At this time, they are very susceptible to saprolegniasis, skin rot disease, bacterial septicemia and other diseases, which can lead to death. If a clarified solution made by soaking fresh garlic and high-quality salt at an 80-100 fold dilution is promptly splashed into the breeding pond, once every 3-5 days, for 2-3 consecutive applications, splashing 2-3 kg per square meter of breeding pond each time, evenly sprinkled on the water surface, the rice field eels will not be infected by the above diseases, and the breeding survival rate will be high.

Occurrence and Prevention Methods of Rice Field Eel Diseases
Rice field eels live year-round in water bodies with complex environmental factors and are frequently attacked by pathogens such as viruses, bacteria and parasites. During the rearing process, sudden changes in water temperature, insufficient dissolved oxygen, excessively high water acidity, and poor feeding management, such as insufficient feed, malnutrition, or feeding rotten and spoiled feed, and deterioration of water quality, disrupt their physiological state, weaken the eel body and lower their resistance, and in severe cases often cause mass death. Even if they do not die, it directly affects the growth and development of the rice field eels. In some cases, it is also due to excessive stocking density, or

Detailed Explanation of Techniques for Self-Breeding Rice Field Eel Fry
1. Selection and Cultivation of Parent Eels. Eels used for breeding must have a robust physique and swim actively. The body color is best in coarse black mud, yellow-brown, or black speckled, green-brown. The source of parent eels should be those caught in cages the same day with relatively small wounds. Rice field eels (Monopterus albus) have sex reversal characteristics; 1-winter-age and 2-winter-age rice field eels are basically female, and after 2-winter-age rice field eels spawn, the proportion of males gradually increases, until at 6-winter-age they are basically male. During the non-spawning season, it is difficult to distinguish male from female; generally, body length and body weight are used as standards, generally body length 37-50 cm, weight 7
