Four aspects of aquaculture structure in Beijing suburb need to be adjusted

Introduction: the aquaculture industry in Beijing is changing from "quantity fishery" to "quality and benefit fishery" According to the shortage of water resources in the suburbs of Beijing and the characteristics of metropolis and large market, the adjustment of aquaculture industry structure should focus on the following four aspects: first, the adjustment of aquaculture species structure That is, to seize the market selling point, with the pursuit of refinement and specialty as the main direction of attack Make full use of the cold spring landscape resources and the hot water resources of geothermal and power plant waste heat in the mountainous area of this city, and develop the cultivation of cold water salmon trout and hot water fish and shrimp Moderately compress the cultivation of conventional warm water varieties At present, the consumption specifications of fresh water aquatic products in the market tend to be "small varieties, large varieties and small specifications" That is to say, the larger the specifications, the better the sales, and the higher the price For example, the average price per kilogram of a crab above 150g can reach more than 120 yuan, about twice the price of a crab around 100g The larger the individual, the smaller the specifications, The market is selling well and the price is moderate Therefore, the breed specification and catching time must be determined according to the market demand to obtain the best benefit The second is the adjustment of cultivation mode We should build and develop high, medium and low-grade water-saving, land-saving, intensive and industrial facilities fisheries according to local conditions, and establish commercial fish bases of tilapia, rainbow snapper, bass, sturgeon and other famous and excellent varieties that can be supplied to the market all the year round and are popular with consumers We will actively develop cold spring water aquaculture in mountainous areas for rainbow trout, golden trout, silver trout, Atlantic trout, and "three nets" of the reservoir Third, the adjustment of regional structure We will continue to consolidate and develop cross administrative and relatively concentrated industrial zones, such as the ornamental fish Industrial Zone dominated by Chaoyang, Tongzhou and Daxing, the cold water fish Industrial Zone dominated by Huairou, Fangshan and Mentougou, the tilapia and rainbow snapper Industrial Zone dominated by Changping, and the fishery standardization Industrial Zone dominated by Pinggu and Shunyi pond aquaculture Fourth, the adjustment of fishery industrial structure We should speed up the development of aquatic products processing industry, increase processing output, and make more aquatic products enter supermarkets and go to the international market To develop sightseeing and leisure fishery, the suburb fishery of Beijing should be built into a production base of green and pollution-free aquatic products as well as a garden style tourism and leisure resort base (author:) share to feed Weibo share to:
