First, 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 pond area is not large, you can use a combination of wood and bamboo to make a simple support on the pond. The shelf is covered with a drip-free plastic film or a general agricultural film (preferably without drip film). When the wind is large or in cold weather, it is covered with a film; when there is no wind, the film can be uncovered at noon; when there is no sun, the film 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.
Second, appropriate warming
In early spring, it is common to use deep-well groundwater in Dianchi, because the water temperature is generally above 10°C. Where there are hot springs, warm springs can be used. In the vicinity of the factory, factory cooling water can be used. Change the water every time 1/2, generally 5 to 7 days. However, it should be noted that the water temperature must not be higher than 3 °C above the temperature of the Dianchi Lake. If the water temperature is too high, it can be introduced into the reservoir for a period of time before reaching the required water temperature and then switching in.
Third, 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. Normal live feeds are fed for about 1 week. Astragalus can gradually emerge from the nest, and then it can be gradually used to spread over the loach, 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.
