The 20th meeting of the Commission for Deepening Overall Reform of the CPC Central Committee adopted the Action Plan for the Revitalization of the Seed Industry, elevating provenance safety to a strategic level related to national security. Factory aquaculture seed industry is an important part of the seed industry, is also a strategic, basic and core industry of fishery, is to ensure the safe and effective supply of aquatic products, and promote the healthy and sustainable development of modern aquaculture industry. The north coast of Changyi City has advantaged conditions for the development of Marine economy. In recent years, Changyi City has made full use of the local superior natural conditions and regional advantages to expand and strengthen the indoor factory breeding prawn seed industry, stimulate the "blue kinetic energy" of economic development, and make every effort to fight the seed industry to recover.



A group of 20 members, including academicians of Chinese academy of engineering, dean of Marine life college of ocean university of China, president of China ocean-going fishery association, relevant expert leaders of ministry of agriculture, deputy director of provincial agriculture and rural areas, went to changyi to investigate the development of aquaculture seed industry. In seed industry technology co., LTD., the panel line workshop, breeding workshop, the scene looked at the storage of shrimp workshop workshop production such as cultivation, scientific research institute of China called the shore, the deputy director of the prawns and genetic breeding, seedling propagation of shrimp cultivation, etc, to carry out technical research situation, as well as the factory indoor farmed shrimp feeds for large-scale propagation progress of the project, The Expert Group highly affirmed the achievements made in the factory aquaculture seed industry, and checked the production record of the project, counted the relevant reproductive data, discussed and concluded the acceptance report and signed it. The results of the inspection show that the cooperation in prawn breeding technology has broken through the technical bottlenecks of multi-trait breeding and the proliferation of standardized prawn without specific pathogenic species, reaching the world's advanced level. At present, more than 450 families of Penaeus vannamei have been independently established, and 50,000 pairs of species of shrimp have been cultivated, which can achieve the market supply of 300,000 pairs of species of shrimp, and fully meet the domestic demand for species of shrimp.

According to the introduction, China is the world's largest producer of prawn, is also the world's first consumer and importer of prawn. Since 1988, when the shrimp was first introduced to China, and from 1997 to 1999, the whole artificial scale breeding technology for the first time was broken through, the South American white shrimps have embarked on a magnificent development path, and the foundation stands at the commanding heights of the global industry. However, on the road of introduction to China, prawn-loving companies have been monopolized by foreign companies for a long time. The number of imported prawn-loving pairs has increased from 150,000 pairs in 2014 to about 300,000 pairs now, and the lack of "prawn-loving" has become the pain of Chinese people. Academician of the Chinese Academy of Engineering and dean of the College of Marine Life at the Ocean University of China told reporters that the price of a pair of imported shrimp can reach as high as $3,000, and China spends hundreds of millions of dollars on imported shrimp every year. It is reported that the total area of Marine aquaculture in Changyi City has reached 420,000 mu, with a total output of 187,000 tons and an annual output of 1.92 billion yuan. Changyi is an important aquaculture base in Shandong Province. Fishery development, seed industry first. In recent years, Changyi City, based on its unique advantages, has actively set up three platforms for seed research and development, breeding and promotion, and large-scale breeding, and promoted the innovative development and chain extension of the Marine seed industry. The independent innovation ability and comprehensive competitiveness of the aquaculture seed industry have been significantly enhanced.



In 2018, Changyi successfully attracted the national aquatic genetic seedling of Bampu Seed Industry and the prawn research and development and breeding project of "Forbes Top 50 Listed Companies in Asia" in Guangdong Haida North Modern Ecological Breeding Demonstration Park, becoming an important factory aquaculture prawn germplasm bank in China. Set up a joint laboratory "prawn breeding" "prawn seed industry development base", the construction of prawn breeding center and 168 standardized farming workshop, the factory indoor farming in South America white shrimp shrimp seedlings cultivation, propagation, cultivation, promotion, cultivation of South America white shrimp shrimp with fast growth, strong resistance, forming rate is high, and the advantages of spawning quantity, Compared with the widely used Penaeus vannamei, the cost of planting shrimp is reduced by 50%, the growth rate of shrimp seedlings is increased by 15%, the annual production of 300 thousand pairs of shrimp can be 240 billion shrimp, the annual output of Penaeus vannamei can be increased by 290,000 tons and the output value is increased by 11.7 billion yuan. Therefore, "Changyi shrimp seedlings" will radiate the whole Bohai Rim region and the main breeding areas such as Zhejiang and Jiangsu, effectively solve the supply problem of high-quality shrimp seedlings in the north, and reverse the passive situation of "south seedlings to the north". It is understood that Changyi will take this opportunity to cultivate industrial chain, strengthen and expand existing enterprises, introduce deep processing enterprises of aquatic products, extend the industrial chain, improve the supply chain and enhance the value chain, and create aquatic genetics and breeding of Bangpu Seed Industry as the source, prawn breeding center and small and medium-sized shrimp seedling breeding enterprises as the link. The complete industrial chain of "integration of breeding, reproduction and promotion" for indoor factory breeding of Penaeus annus with the terminal of the northern modern ecological breeding demonstration park of Haida in Guangdong Province can achieve an annual output of 12,000 tons of Penaeus annus with an output value of 620 million yuan.
