In January and September, it was an important period for the cultivation and stocking of conventional fish seedlings. Therefore, from July to September, summer flowers and fish species cultivation should be done. Before the stocking, the seedlings should be sterilized in a timely manner. When stocking, they must be sterilized with salt water or potassium permanganate to prevent bacterial infection. To purchase seedlings from other places, it is necessary to carry out disease detection and quarantine so as not to bring in pathogens.
2. Management of adult fish farming: (1) July-September is the peak season for fish growth, and fertilization and feeding should be strengthened. Ponds with mainly fish and fish should be topdressed according to their color and transparency. Ponds or cages that eat mainly fish should be fed in a timely manner. And do feed "four set" (quality, quantitative, positioning, timing), fertilization, "four look" (see fish, see the sky, see the water, see the season); (2) pay attention to water quality control. According to the weather changes in time to increase oxygen and water. Due to the rapid growth of fish in July-September, the amount of food consumed increased, excretion increased, and the water quality was prone to deterioration due to lack of oxygen. Therefore, aerobic machine oxygenation should be started every day. In case of hot weather, it is necessary to extend the time for starting oxygen. At the same time, it is necessary to frequently add new water, raise the water level to more than 1.5 meters, and replace some of the bottom water properly. Promote the use of beneficial microbial agents to improve water quality and sediment quality. During high temperatures, it is best to apply photosynthetic bacteria or other microbial agents such as Bacillus once every 15 days; (3) Prevent diseases. From July to September, the temperature is relatively high, but the water temperature is relatively suitable. Various pathogens in the water are prone to breeding and breeding. This is the season in which fish are susceptible to disease. If ignorance of prevention can easily induce fish disease. In July and September, the major diseases that are prone to be outbreaks and epidemics are bacterial hemorrhage, gill disease, enteritis disease, anthelminthosis, Chinese sturgeon disease, and ringworm disease. The focus should be on prevention of bacterial bleeding and parasitic diseases. Regular use of lime, chlorine dioxide, dibromohydantoin, and insecticides and other fishery drugs spilled and disinfected. (4) Strengthen day-to-day management and stick to duty on duty. From July to September, the weather is changeable, and thunderstorms and typhoon weather are prone to occur. Attention should be paid to observing the eating conditions of fish and oxygen-depleted floating heads. It is necessary to add new water and oxygen aerators in time to prevent signs of hypoxia. .
