Summer is the golden season for the cultivation of jaundice, but this season's hot weather, rainy days or thunderstorms in the evening, the water quality will be seriously deteriorated, so we must grasp the following five key links: 1, cooling down 2, feeding off Summer temperatures are high, ensuring that the quality of the feed is important. The feeds, especially animal feeds, must be fresh and have been deteriorating. The rancid bait should not be fed. The scutellaria baicalensis grows fast in summer, and it is necessary to feed as much animal protein diets as snail meat, live quail, and fly maggots as much as possible and feed it twice a day, ie before 9 o'clock in the morning and after 6 o'clock in the afternoon. In case of bad weather, the food intake of Astragalus membranaceus is reduced, and the remaining bait should be removed in time so as not to deteriorate the residual bait and pollute the water quality. 3, transfer water off Pay attention to the adjustment of water quality pH. Although Astragalus prefers to live in a slightly acidic environment, the acidic environment is conducive to the growth of pathogenic microorganisms in the case of a high density of artificial rearing, which causes the disease to become infected. Practice has proved that the ph value of water in summer eel pools is suitable for controlling between 7 and 8. 4, prevent escape When the weather suddenly changes in the summer, especially when thunderstorms, heavy rain, and jaundice appear to be irritating, it is easy to escape. In severe cases, one can escape overnight. Therefore, when the weather suddenly changes in the summer, special attention must be paid to avoiding escaping. Regularly check the depth of the water level, whether there are cracks in the pool wall and the bottom of the pool, and whether the drainage hole is blocking the fishing nets in order to eliminate hidden dangers in time and stop the way out of the yellow locust to escape. 5, floating head clearance In the hot weather, rainy days or evening thunderstorms, severe deterioration of water quality, bubbles on the surface of the water, etc., when the morning and evening patrol pool found the water surface of the cluster of yellow peony, scattered floating, shocked and beating, indicating that the pool water is severely deficient in oxygen, must take measures to deal with quickly. For light floating heads, new water can be injected in time to increase the dissolved oxygen in the water. In summer and early autumn, dark floating heads are easy to appear. Due to mild symptoms, they are not easy to detect and are prone to flooding. It is necessary to observe carefully, and once they are found, they must immediately prevent water injection; The floating head caused by the sudden changes in water quality should reduce the feeding, remove the bait residue, and inject fresh water as soon as possible. Pay attention to adding new water should not be carried out in the evening, so as to avoid convection of the upper and lower aquifers, but intensify the floating head.

The maximum adaptation limit of jaundice to high temperature does not exceed 28°C. Exposure to the sun in the hot sun can rapidly increase the temperature of the pool water, and it is prone to heat stroke and even burnout. Therefore, controlling the pool water temperature is critical.
The main cooling methods are: 1. Build a shade shed on the top of the pool to cover the shade net. 2. Put appropriate amount of floating plants on the surface of breeding ponds, such as water hyacinths, water lilies, duckweed and other shade. 3, irrigation cooling. Deepen the water level in the pool to 25-30 cm, and replace the surface water in the pool by irrigation to balance the pool water temperature. Conditional farmers can adopt the method of daily micro-flowing water to reduce the temperature and have better results.
