Description

technical field [0001] The invention belongs to fish medicine, in particular to a fish medicine for treating small melon worm disease. Background technique [0002] Small melon worm disease is a common fish disease. The body surface and gill flaps of the diseased fish are covered with white dot-like worms and cysts, which are visible to the naked eye, so it is also called white spot disease. The mucus on the head, trunk and fin rays of the body surface increases significantly, and it is mixed with the insect body, which seems to have a thin film. The melon worm disease has an obvious onset season, and spring, autumn and early winter in the south are popular seasons. After the mature melon worm leaves the fish body, the body secretes transparent and elastic cysts, sinks to the bottom of the water or attaches to aquatic plants and plant debris, and then begins to divide. After 9 to 10 divisions, 300 to 1000 larvae are formed. At 15 to 20 degrees Celsius, after about 24 hours...
