1. Fall Management: In the fall, the northern air mass gradually descends to the south, and the climate begins to cool and the temperature drops. In early autumn, there are more storms and more rainfall.
(1) Full attention should be paid to the maintenance of drainage and irrigation systems and the reinforcement of plastic sheds to prevent storm damage.
(2) Grasping time for fattening, preparing for hibernation on nutrient reserves, and making Chengyu achieve higher listing standards. Should choose a better diet and add vitamins and minerals. Because of the fact that it is necessary to restore post-partum fatigue, the bait also needs to be mixed with fresh fish and snail meat.
(3) Sheng Qiuyu is born more often and needs to be cultivated with conventional seedlings. Note that the warming tank must be cleaned and disinfected prior to delivery. The temperature of the water rises to 30°C and can be put into the baby. After that, it is necessary to constantly check the water quality to deteriorate the waterproof quality.
(4) At the end of autumn, prepare for the winter and prepare for the next year's breeding plan. Choose a sunny day to clean out the pool and weigh and measure it. After the disinfection and improvement of Dianchi Lake, the high-density and centralized stocks planned to be listed are kept at a water level of 35 to 40 cm and ready for sale. Intimate and need to continue breeding into the wintering pool, let it hibernate naturally. The juveniles also need to be divided into pools again in order to reduce the breeding density and avoid mutual bite injuries due to individual differences. The juvenile bait at this time can be replaced with a high-protein diet that feeds salmon.
2. Winter management: The winter climate is controlled by the Siberian air masses. The weather is cold and dry. The average water temperature is below 20°C and it is the winter hibernation period.
(1) The pro-gills and clams that are kept at room temperature are mainly supplemented with the reduced moisture due to evaporation in a timely manner to maintain the stability of the water level in the pool and to regularly inspect the pool embankments to prevent water leakage.
(2) When there are conditions, the juvenile pool can be warmed to keep the water temperature constant at 26 to 30°C. At one time, the weight of juveniles was measured one time in order to correct the feeding amount and adjust the stocking density. The food can be gradually added some live bait to balance nutrition and promote rapid growth.
