Autumn and winter management of carp
Squid is a semi-hibernating fish. When the temperature is below 15°C, the carp does not eat, and it enters hibernation by micro-breathing. Therefore, after entering the autumn, the temperature gradually decreased, and the eel's feeding and activities gradually weakened. At this time, the management of autumn and winter needs to be strengthened. The main measures are: First, increase the feed with high fat content so that the carp can accumulate more fat for the consumption of fish when they are in hibernation. Feeds with high fat content include cocoons, cockroaches, and fly maggots. Feed them as much as possible. Second, a reasonable capture of listed squid like to drill into the pool bottom silt, especially after the temperature dropped, will drill into the silt over the winter. For this reason, for Chengyu, it is reasonable to capture the listing 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 shovels, shovels, and other hard sharps to dig deep enough to cut or bruise the squid. At the same time, we must pay attention to catching up and keeping small so that we can breed eggs in the coming year. Third, to strengthen the overwintering protection of water conditions better Dianchi, you can use deep water overwintering method, that is, to maintain a depth of 50 cm to 70 cm in the pool of water, and put some water plants, duckweed, etc. in the water, when the winter ice , knock open ice permeability. In this way, both the bottom temperature and the oxygen content of the pool water can be maintained. When the squid began to hibernate, the pool was allowed to dry for winter. 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 animals such as cats and dogs from preying on salmon. In case of freezing cold, the pool surface should be covered with a layer of straw or other stalks, insulation and antifreeze. When the temperature rises above 15°C in the coming spring, feeds should be promptly fed to promote the growth of salmon.
