1, water quality management. The water depth in the room is kept at 5-8cm and it stays about 10cm outdoors. It can be deepened to 15-20cm in hot season. Due to the shallow water level, the carp excretion is large and the water quality is easily deteriorated. Therefore, change the water more frequently, which is the key to aquaculture without water, usually 3-4 days in summer, once in spring and autumn, and change the water every time. Production practice shows that the complete replacement of water conservancy in pest control counties does not affect the growth and development of carps. 2, feeding. After stocking the fish, it takes 7-10 days or even longer to acclimate the squid to feed on the compound feed (the feed is wetted into a ball or twisted into a strip with a meat grinder), and after the food is normal, the feed should be “timedâ€. , quantitative and fixed points, and take corresponding management measures by observing the feeding situation of squid. 3, pest control. It is mainly prevention. The main diseases and pests in still waterless culture include capillary nematode disease, enteritis disease, bacterial rotting disease, print disease, and erythroderma disease. After the domesticated food has been successfully eaten, the drugs (such as trichlorfon and anthelmintic) are mixed and killed immediately. The control of other diseases is similar to that of aquaculture. 4, more summer. Relatively speaking, indoor summer is easier. It is necessary to consider shade in outdoor farming, deepen the water level at high temperatures, and adjust the temperature with groundwater. 5, winter. Usually over the winter in the earth aquaculture ponds, divided into two types with or without water overwintering. The depth of water with water is about 20cm in winter, but it is necessary to put grass, branches and other objects to prevent the whole pool from freezing. Without water, it will be drained before it hibernates in winter, and the mud will remain moist. It will be safely overwintering with insulation materials such as straw. Where conditions permit, the indoor temperature in winter is kept above 15°C, so that the carp breaks dormancy, and it can still grow in winter. Before and after the Spring Festival, the sale of commercial plutonium is more desirable.
