The temperature difference between day and night in autumn is relatively large, and it is easy to cause deterioration of water quality. Fish disease has also entered the second multiple period. In order to effectively help farmers to manage the fisheries in the autumn and do a good job of prevention and control of fish diseases, the Shandong Provincial Urban Aquatic Products Bureau takes active actions and takes Three measures prevent fish diseases. 1. Strengthen monitoring to ensure safe aquaculture environment. In the autumn, after several months of fish growth, the ponds have high density, large amounts of fertilizer for feeding, and large amount of organic matter in the water, and the water quality is easily deteriorated. The aquatic animal disease prevention and control stations are fully utilized, and regular sampling of water quality is conducted at key breeding sites. The pH, temperature, ammonia nitrogen, etc. were measured to provide a reliable scientific basis for preventing fish and shrimp disease. Scientific guidance to farmers for the prevention and treatment of fish diseases to ensure the safety of the breeding environment, so that "mainly prevention, prevention and control combined." 2. Strengthen drug guidance and ensure the safety and quality of aquatic products. Through fishery home-based experts and instructors, they have established extensive links with farmers in various ways, such as directing farmers to use drugs scientifically, achieving symptomatic, timely, appropriate, and correct methods of drug use; on the other hand, directing culture The households selected FDA-certified fishery medicines and refused to use illicit drugs. They strictly implemented the withdrawal period system for some rounds of catcher ponds to ensure the quality and safety of aquatic products. 3. Strengthen the training of fishery science and technology demonstration households and farmers of various townships in the prevention and treatment of aquaculture diseases. In the face of the uneven quality of fishermen in Yucheng City, and different levels of farming skills, the “inviting and going out†approach is adopted to increase training, and in conjunction with fishery science and technology, household training will be adopted. Conduct lectures; promote parallelism and simultaneous guidance; send medicines to the countryside, serve the frontline and other measures. The quality of fishery technicians at the grass-roots level has been strengthened, and the skill of fishery workers in breeding and the level of disease prevention and control have been improved, and immediate results have been received. 2022 New Laser Distance Sensor
