In summer, the temperature is high, the temperature difference between day and night is large, the temperature difference between the upper and lower sides of the water body is obvious, and the water quality changes rapidly. Especially when the continuous high temperature occurs, the farmed fish are affected by environmental changes and the stress response is intensified, and the resistance is reduced, which can easily lead to disease occurrence and epidemic, resulting in economic loss. During the summer cultivation process, especially when there is a continuous high temperature, the following technical points need to be noted in the aspects of aquaculture management and fish disease prevention and control: First, regulate water quality and create a suitable breeding environment. 1. Appropriately add new water, generally add 7 or 10 days of water or change the water once, change the water every time by 10 to 15 centimeters, and keep the water level at 1.5 to 2 meters. When you add new water, try to avoid flushing the bottoms. 2. Ponds with a water depth of more than 2.0 meters are best equipped with cultivators and diligent aerators to promote the exchange of upper and lower water layers or the circulation of water. 3, Quanchip splash lime to improve water quality is obvious, every 10 to 15 days per cubic meter of water body dose of 25 to 30 grams of lime thrown lime once. 4. The application of photosynthetic bacteria, Bacillus and other microecological preparations can effectively improve the microbial ecological environment of aquaculture water bodies. 5. If the plankton in the water body is abundant and stable or after the application of the probiotics, try to avoid administering the drug. 6. If cyanobacteria blooms appear in the culture ponds, strengthening the circulation of the pond water can effectively suppress the blue-green algae outbreak. The 0.5-gram dose per cubic meter of water in the Quanchiposa can effectively kill cyanobacteria. In the splash of copper sulfate on the same day to strengthen oxygen, to avoid flooding ponds, in the splash of copper sulfate after 3 to 4 days, you can splash a quick lime in Quanchipia, improve water quality and sediment. Second, scientific feeding, enhance fish resistance. 1. It is advisable to set one feeder per 15 to 18 mu water surface to avoid a large number of fish gathering in a single place. 2. Ponds with a water depth of more than 2 meters should reduce the feeding time. It is advisable to feed 20-30 minutes at a time. 3, under continuous high temperature conditions, in particular, adhere to the "quality, quantitative, timing, positioning," feeding, to ensure feed quality, supplement fish vitamins and trace elements, improve the body's resistance. 4, in the vicinity of the food market to take bags, hanging gongs method, the use of copper sulfate, bleaching powder and other disinfection sterilization insecticide to prevent pathogen infection. The specific method is: use a bamboo or other triangular or square food field box, hang a bamboo basket on each side, expose the surface of the water, put 100 grams of medicine into the bowl, change the medicine once a day, and then hang it for 3 days. Disinfect the food field; add allicin and other antibacterial drugs to the feed to prevent intestinal diseases by using 0.5 kg of garlic per 100 kg of fish, mash together with 200 g of salt, mix in the flour paste, and mix the cold with the feed. After feeding, feed 2 to 3 days. For crabs, crayfish and other breeding objects, they must adhere to the principle of reasonable collocation of fine, green, and rough feeds. Concentrates are best made into food groups and placed on a multi-place food table. Feeding table food feeding method is the most effective method for immune promotion, metabolic improvement and drug prevention of crabs, crayfish, etc., and can ensure sufficient intake of drugs. Third, appropriate thinning, gradually reduce the breeding capacity. The culture density should be scientific and reasonable, so that the self-purification capacity of the pond and the amount of organic pollution are basically balanced. According to pond conditions, supporting conditions and technical standards, etc., to stocking fingerlings is generally controlled at 800-1000 kg/mu. In high-temperature or continuous high-temperature weather, do not use the whole pool to pull the net, it is recommended to use the attached table in the food platform to set up fishing nets, catch large and small, not only reduces the breeding capacity, increase the efficiency of capital flow, It also reduces the impact on fish, water quality, and pond ecology. After net fishing, suitable conditions can be properly supplemented with small-scale fish species to ensure the utilization of water and aquaculture production.
