Astragalus is a semi-hibernating fish. When the temperature is lower than 15 °C, the carp will basically not eat, rely on micro-breathing into the hibernation. Therefore, when entering the fall, the temperature gradually decreased, and the carp's feeding and activities gradually weakened. At this time, by strengthening the optimization management of autumn and winter, not only can continue to increase weight gain, but also can increase the survival rate of overwintering, which will help increase the output in the coming year. Huang Qiu's autumn and winter optimization feeding management measures mainly include the following: First, increase the fat feed. Increasing the feed with high fat content can allow the carp to accumulate more fat for the consumption of hibernating and wintering. Feeds with high fat content mainly include cocoons, cockroaches and fly maggots. To increase the amount of fat feeds for yellow locusts, feed as early as possible, generally should be carried out before November, because the temperature in autumn is still relatively high, which is conducive to the utilization, absorption, and conversion of squid for fat feed, and increase its required energy for wintering. Strengthen its ability to fight against cold and disease in winter. Second, a reasonable capture of the listing. The squid has the characteristic of preferring to enter the mud at the bottom of the pool, especially when the temperature in the late autumn is significantly reduced, it will cause people to overwinter in deep silt. Therefore, for Chengyi that meets the market specifications, it is advisable to capture the listing as soon as possible before winter. When catching, the pool water should be drained first, and the surface mud should be removed, and then the mud in the bottom of the pool should be captured with both hands. Avoid using hard sharps such as shovels and shovels to dig and prevent cutting off or bumping the carcass. At the same time, it is necessary to keep large and small in order to lay eggs for reproduction in the coming year. Third, strengthen winter protection. Two species of wintering carp remain in the pond for winter protection: First, Dianchi Lake, which has better water sources, can use deep water overwintering method. That is, keep a depth of 50 to 70 centimeters in the pool and place some aquatic plants and duckweed on the water. When it freezes in winter, knock on the ice to breathe. In this way, not only the bottom temperature can be maintained, but also the oxygen content of the pool water can be maintained, creating an ideal wintering condition for the squid. Second, Dianchi Lake, where the water conditions are not good enough, can dry up when the carp begins to hibernate. However, it should be noted that the pool soil should be kept moist and not too dry; plastic nets should be placed on the pool soil to prevent cats, dogs, weasels, rats and other animals from eating predators; in case of freezing cold, the pool surface should be covered with insulation.
