Several Practical Measures for the Prevention and Treatment of Rice Field Eel Diseases

Introduce or transplant certain aquatic plants with medicinal value into the eel pond to achieve the purpose of disease prevention and treatment. For example, introducing purple-backed duckweed into the eel pond and keeping it growing vigorously can prevent rice field eel fever, "heatstroke" and "colds". Planting water pepper or sweet flag on the pond banks can prevent and treat red-skin disease.

Tie fresh grass into several small bundles and soak them in the mud banks, pond or net cages to prevent and treat diseases. For example, to prevent and treat red-skin disease and enteritis, use 150-200 g of fresh castor leaves or tender twigs per 50 sq m of water surface, tie them into several small bundles, insert them into the mud bank and let them rot naturally, for 3-4 days each time, 2 times in succession.

Mash fresh tender Chinese herbal medicines and soak them in the eel-rearing water body to achieve the purpose of disease prevention and treatment. For example, mash 2.5 kg of fresh water pepper, put it into 1 cubic meter of eel-rearing water and let it soak for several days, which can prevent and treat rice field eel rotten-intestine disease.

Grind sun-dried Chinese herbal medicines into powder, mix with water or directly scatter evenly into the eel-rearing water body to achieve the purpose of disease prevention and treatment. For example, grind Chinese gall into powder, dissolve it with boiling water, and splash it over the whole pond; the dosage is 2-4 g per cubic meter of pond water, which can prevent and treat rice field eel red-skin disease, furunculosis, etc.

This is one of the most common methods of using Chinese herbal medicines to prevent and treat diseases. Decoct dried or fresh herbs in water over low heat until concentrated; after boiling, simmer for about 5-10 minutes, filter out the residue, let it cool, and splash it over the whole pond to achieve the purpose of disease prevention and treatment. For example, per cubic meter of water body, take 100 g of bloodwort, 100 g of Jijiesu, 50 g of humifuse spurge, 20 g of phyllanthus urinaria, 35 g of purslane and 100 g of false daisy, decoct in water over low heat until concentrated, filter out the residue and splash over the whole pond, which can prevent and treat rice field eel tail-rot disease, enteritis, print disease, water mold, etc. Using a decoction of lightyellow sophora root (100 g of lightyellow sophora root added to 2 kg of water, boiled and then decocted over low heat until concentrated), use 8-11 g of lightyellow sophora root per 50 sq m, repeat once every other day, 3 times in succession, which can prevent and treat print disease.
