1. Adjust the temperature difference. The cages are pre-placed in the reservoir bay. When the temperature of the fish ponds and the water temperature of the reservoirs differ by more than 3°C, the temperature difference should be gradually adjusted. After the fish species is adapted to the water environment of the reservoir, the fish species can be put into the cage. Reservoir. The method is to gradually add the reservoir water to the tank of the shipped fish species. When the temperature of the water in the tank to be shipped is close to the reservoir water temperature, stay for 10 minutes to 30 minutes. Slowly pour the fish species and the water into the cage. To adapt the fish species to the new water environment, allow the fish species to freely swim into the reservoir after 120 minutes of raising in the cage.
2. Drug prevention. According to the characteristics that the water temperature of the reservoir is often lower than the temperature of the water in the fish pond, garlic juice can be combined with urea to prevent the “acclimatization†of the fish species. It has a good effect and has no side effects on the fish species. 1.3 kg of garlic juice is added for every 500 kg of water. After the fish is put into the water tank, 2.5 kg of urea is added to each 500 kg of water to make it sink into the bottom of the tank. When the urea dissolves slowly, it absorbs the water tank. The heat of the water makes the temperature of the water in the fish transport box slowly decrease, which helps the fish to adapt to the lower water temperature environment.
Every winter is the golden season when fish, eel, grass carp, and herring are used for reservoirs. However, many fish farmers have reported that during the 2 to 7 days of feeding fish species, a large number of dead fish and floating sick fish are found on the water surface of the reservoir. The skin of these fish is dull and the surface mucus is increase. Based on the above symptoms, it can be inferred that the fish had a typical "soil and water". The disease is mainly caused by the drastic changes in water temperature and the stimulation of internal organs caused by strong stimulation of the skin's nerve endings. The mortality rate is as high as 20% to 60%, causing serious economic losses to the fishermen. So, how to prevent the disease from happening?
