Autumn Prevention and Control Methods for Fish Fulminant Hemorrhagic Disease
Fish are prone to fulminant hemorrhagic disease in autumn. This disease has a sudden onset, spreads quickly, and has a long epidemic duration, with a high mortality rate and heavy losses. Once it breaks out, it is difficult to control, and the condition tends to recur. Fish farmers should strengthen their awareness of prevention to prevent the occurrence of this disease. 1. Disinfection of fingerlings Before fingerlings are stocked into ponds, they must be soaked and disinfected in 1% to 2% salt water. The soaking time depends on the fish's constitution and the temperature. When conditions permit, fingerlings can be soaked with fulminant hemorrhagic disease vaccine. 2. Timely water exchange and oxygen enhancement The water quality must be kept fresh,

What are the prevention and treatment methods for toxic water disease in fish?
Water is the air that fish breathe to survive. In recent years, water bodies have suffered pollution (such as excessive dissolved oxygen, excessive metals, water oxygen deprivation, etc.), causing toxic water disease in fish and resulting in mass deaths. The following methods can be used to diagnose and rescue fish suffering from toxic water disease in water bodies. 1. Toxic water disease from excessive dissolved oxygen. Excessive dissolved oxygen in water bodies can cause eutrophication, leading to bubble disease and many other illnesses in fish. 1. Harm and symptoms. Because too much unfermented fertilizer is applied to the water body, fine small bubbles of methane and hydrogen sulfide are decomposed at the bottom of the pond, and fry mistakenly swallow them as food. The main symptoms are that many small bubbles adhere to the fish gills, causing the fish body to float upward or lose balance; there are white bubbles in the fish intestines, or many bubbles attach to the body surface, fin rays, and gill filaments, and the fish body floats on the water surface, which can cause fish death in severe cases.
