What should be paid attention to when releasing fish fry in winter in the reservoir
Every winter is the golden season for releasing silver carp, bighead carp, grass carp and herring to the reservoir. However, many mariculturists report that a large number of dead fish and swimming diseased fish will be found on the water surface of the reservoir within 2 ~ 7 days. The skin of these fish loses luster and the body surface mucus increases. According to the above symptoms, it can be inferred that the fish is suffering from a typical "incompatibility of soil and water". The disease is mainly caused by the sharp change of water temperature and the strong stimulation of nerve endings in the skin of fish, which leads to the dysfunction of internal organs and its death.

Common diseases of parent fish and their prevention and treatment
1. The pathogen of vibrio is Vibrio alginolyticus. When the fish is sick, it is slow to move, often swims out of the water, and the food intake is reduced or not eaten; the ends of the caudal, ventral and dorsal fins are congested and inflamed, and the tissue between the fins spreads gradually, and when the fin fester is severe, the festering focus of the body surface of the diseased fish is uncertain, and in serious cases, it rotates into a deep hole, the bones are exposed, and Vibrio can be isolated from blood and internal organs, resulting in a high mortality rate. Prevention and treatment: ① uses vaccine to immunize fish. Soak in ② drugs, usually with 100ppm
