1. Change the traditional aquaculture model to ensure a balanced market for aquatic products. The first is to change the feeding structure of fish species. First of all, according to the requirements of the wheel catcher, a certain percentage of fish species that are listed in the market will be placed in winter each year so that they can be put into the market in the season of high sales of aquatic products; secondly, the requirements for listing large varieties in small sizes and small varieties in large sizes will be required. , to put in different specifications of fish species; again, increase the amount of grass carp, carp and carp feeding, reduce the amount of carp, carp, carp feeding. The second is to raise adult fish. After entering the fish pond dry pool in winter, part of the adult fish will be raised in the fish pond and will be sold in spring. The third is to set up cages in the pond. The live special aquatic products captured in peacetime will be put into cages for raising. When the market price rises, they can be picked up at any time. According to the actual situation in the local area, the above methods can be used flexibly to ensure that there will be fresh aquatic products available throughout the year and the economic benefits will be significantly improved. 2. To optimize the structure of aquaculture species and promote the breeding of new and special aquaculture species. With the development of the aquaculture industry, consumer demand for aquatic products has emerged in two major characteristics: First, the demand for high-quality aquatic products has increased; second, it has shifted from seasonal demand to annual demand. Therefore, market-oriented optimization of aquaculture species structure and promotion of aquaculture and breeding of new and famous aquaculture species are important ways to adapt to changes in the market supply and demand relationship and increase the economic benefits of aquaculture. The first is to develop and use existing aquaculture species (such as carp, squid, and Wuchang fish). The second is the introduction of new varieties of aquaculture (such as tilapia, stingray, catfish, squid, freshwater whitefish, Macrobrachium rosenbergii, etc.). Thirdly, aquaculture species (such as wild pheasant, yellow peony, etc.) that have long farming cycles, high market prices, and are favored by the people can be developed according to local conditions and gradually form large-scale production. 3. Open up feed resources and reduce feed costs. The cost of feed accounts for about 70% of the total cost of aquaculture. Extensively developing feed resources and reducing production costs are effective ways to increase the economic benefits of aquaculture. The first is grass-fish farming. The second is the combination of fishery and husbandry. According to the needs of fishery and fertilizer, the scale of raising pigs and poultry will be maintained, and the integrated breeding mode of fish and livestock combination and fish and poultry will be adopted to establish a benign ecological cycle. In this way, it can not only increase the output of aquatic products, but also reduce the cost of grain and greatly increase the overall economic benefits of aquaculture. The third is to popularize feeds for fish farming, shorten the aquaculture cycle, and achieve high-yield and high-efficiency production. 4. Comprehensive prevention and control of fish diseases. In recent years, fulminant fish disease has largely constrained the development of the aquaculture industry. Based on the characteristics of fish diseases, we adhere to the principle of “mainly prevention, combination of prevention and control, and unremitting efforts.†We must implement comprehensive disease prevention measures that combine ecological control and drug prevention and control. This will prevent the occurrence of fish diseases, reduce breeding costs, and increase Aquatic product quality and aquaculture efficiency are of great significance. The first is to change the fish species in the past to release the winter fish species in the spring so that the fish can enter the normal growth period earlier and enhance its disease resistance. The second is scientific feeding and fertilization. Apply less, diligently fertilize materials to keep the water quality fat, live, tender and cool. The third is to attach importance to drug control. Fish species should be disinfected prior to stocking to prevent pathogens from entering the pond. In the epidemic season of fish disease, drugs are regularly used to disinfect water bodies to prevent the occurrence of fish diseases.
