Early spring jaundice to eat early

In early spring, the temperature is relatively low, and the scutellaria baicalensis does not eat, and it grows slowly. How to manage the early spring feeding and management, so that the early start of eating Huangpi is the key to improving aquaculture production and increasing income. According to the characteristics of low temperature and low light in early spring, we should do a good job in the following tasks to promote the early start of eating Huangpi. 1, pay attention to insulation. The temperature in the early spring is low, and there is little hole activity in the jaundice. In the artificial breeding, the insulation work needs to be done well, so that the temperature of the small environment in Dianchi Lake can be increased, so that the yellow praying can be eaten out of the hole. If the size of the pond is not large, it can be used as a simple support for the use of mixed wood and bamboo on the floor, and a drip-free plastic film or general agricultural film (preferably no liquid film) can be used on the rack. When the wind is large or in cold weather, it can be covered with a film; when there is no wind, the film can be opened and deflated slightly at noon; when there is no sun, the sun can be exposed at the noon, so that the heat storage in the Dianchi Lake and the plants in the pool can be fully used for photosynthesis. 2, appropriate warming. In early spring, the change of water in Dianchi Lake generally uses deep well groundwater, because the water temperature is generally above 10°C; where there are hot springs, warm spring water can be used. 3. Feed the bait. In the early spring, when the oysters start to eat, the bait requires all live bait. The best bait is live quail, followed by Tenebrio molitoris, and then snails, quail meats and so on. With live bait, the appetite of the jaundice can be quickly adjusted and the physical strength of the jaundice can be restored. Generally live bait is fed for about 1 week, and Astragalus can gradually emerge from the nest, after which it can gradually use other bait. It is better to put the bait on the mud for the first time, but the amount should not be too much. The next day, if there is a surplus of bait in the pool, the amount of bait should be reduced; if the bait is eaten, the amount of bait should be increased appropriately. When a large number of oysters come out to eat, they should be changed to feeding at the food station.
