In the summer, the warm water of the day, the physiological function of the prawns, food intake increased significantly, should be the peak period of growth of shrimp. However, practice has shown that in the summer, the speed of shrimp does not increase, but it decreases. This situation is mainly related to high summer temperatures. In midsummer, the daily maximum temperature in most areas along the coast of China is above 33°C almost every day. In general, the surface water temperature is relatively close to the temperature, but the maximum difference is 1～2°C, and it is often maintained at about 30°C. Far more than the optimum growth temperature of shrimp (19 ~ 25 °C), thus affecting the rapid growth of shrimp. However, prawns living in natural sea areas have already avoided deeper waters and have been nocturnal during the day. During the day, they spend 10 to 20 meters deep on the seabed to enjoy the cool air. During the night, the temperature of the upper water drops before they feed on the upper waters. Suitable water temperature. Pool shrimp is not the case, even if the bottom of the reservoir is still only 2 meters deep, and 2 meters deep water temperature is only 2.4 degrees lower than the surface temperature, still in the high temperature of 28 ~ 30 °C. Under the stimulation of high water temperature environment, the physiological function of shrimp, body temperature increased, loss of appetite, prone to hyperthermia, affecting the growth rate, such as encountering unclean water, low pressure and rain and other adverse weather, but also lead to pan. So, how to overcome the negative impact of high summer temperatures on shrimp aquaculture? The first is to increase the daily water exchange capacity of the shrimp pool water and achieve the purpose of reducing the water temperature. At present, the daily water exchange capacity of general shrimp farms is 8% to 10% of pool water. If it is increased to 20%, the growth rate of shrimp will be significantly improved; the daily water exchange capacity will be increased to 30%, and the growth valley of shrimp will disappear in the midsummer; if the daily water exchange rate reaches 50%, the shrimp growth peak may occur and the yield per mu can be achieved. 400 to 500 kg, shrimp body length is also close to the shrimp. Second, the shrimp pond should not be too shallow. At least the water depth should be kept at 2.5 meters or more to provide a water environment for the shrimp to avoid the heat. Third, shrimp farms that do not have a large number of water-changing conditions should, in the high-temperature season in midsummer, reduce the amount of feed to prevent the residual bait from excessively contaminating the pool water, causing hypoxia and other diseases.
