First of all, it is an opportune time to use the Spring Festival to achieve the early sale of fish that meets the specifications for the return of funds. If the market for supply of aquatic products exceeds demand, the price is really sluggish, so it is possible to carry out temporary stock raising and avoid off-season sales. However, we must master the heat, do not commit "reluctant sellers" problems, the shot when the shot, trying to sell a suitable price. Second, we must use the winter leisure time after the Spring Festival to calculate the cost of production for one year, and make profit calculations to make a good annual summary. It is necessary to select the best breeding mode and production mode from the annual summary, and sum up the successful experience and the lessons of failure in order to lay a solid material foundation for the new year's fishery production. First, the winter management of adult fish should strengthen the feeding and management of the upcoming fish, especially to do anti-theft work. Second, winter management of fingerlings should strengthen wintering management of fingerling production, deepen pool water, and do wintering work well. Third, the excavation and regulation of fish ponds requires comprehensive planning and design of the newly excavated fish ponds. It is necessary to select places with convenient drainage, good water quality, and convenient transportation, and complete the pond renovation projects in time. Fourth, production arrangements should be based on market demand, according to local conditions to choose the mode of aquaculture and breeding species, reasonable arrangements for stocking plans, timely release of fingerlings. Many farmers are accustomed to stocking after the Spring Festival. In fact, this is not scientific. The spring temperature gradually rises, the scales of the fish are loose, and the fish body is easily injured, affecting the survival rate of the fish species. Farmers raising grass carp can inject grass carp vaccine at this stage.
