Midsummer is a critical period for freshwater fish farming. In order to ensure a stable and high-yield aquaculture, farmers should strengthen the following four aspects of aquaculture management: Enhanced fertilization feeding At this point, the fish grows most prosperously and the feed coefficient is low. For ponds with mainly fish and fish, they should be topdressed according to their water color and transparency. For ponds or cages that mainly eat fish, feeds should be fed in a timely manner. The number of feeds can be controlled flexibly according to specific circumstances, and persist in achieving Four set" and "four look." Pay attention to water quality regulation Due to the high temperature of summer water, fish grow faster, food intake increases, excretion increases, and water quality deteriorates, resulting in lack of oxygen. Therefore, aerobic machine oxygenation should be started every day. Open aerators to regulate water quality at 2-3 o'clock in the sunny day. If hot weather is encountered, extend the oxygenation time. At the same time, it is necessary to frequently add new water, generally adding water or changing water once every 7-10 days, changing the water every time by 10-15 centimeters. Raise the water level to more than 1.5 meters, and stir the bottom of the pool regularly to promote the metabolism of the material, and replace some of the bottom water properly. Promote the use of beneficial microorganisms to improve the quality of water and sediment, it is best once every two weeks to apply once photosynthetic bacteria, Bacterial Vibrio or EM bacteria and other microbial agents. Do a good job of disease prevention Midsummer water temperature is more suitable for various pathogens in the water, which is easy to grow and breed. It is the season when fishes are easy to attack. The main diseases that are easily outbreaks and epidemics are bacterial hemorrhagic disease, gill disease, enteritis disease, sporeworm disease, anchor head disease, and Chinese sturgeon. Diseases and ringworm disease. Farmers should do a good job in the prevention of bacterial hemorrhage and parasitic diseases: food counters should be cleaned every 10 days, and fishery chemicals such as quicklime, chlorine dioxide, dibromohydantoin, and trichlorfon should be regularly disinfected. Strengthen day-to-day management In the summer, the atmosphere is changeable, and thunderstorms and typhoon weather are prone to occur. The work of preventing fish from running away should be done, such as timely reinforcement of dikes, repair of pool dams, and attention to the maintenance and reinforcement of fish and fish installations to prevent fish from being damaged. In addition, we must pay more attention to the observation of fish eating and oxygen-depleted floating heads, and find that the signs of hypoxia should be filled with new water and aerators in time to avoid flooding fish.
