Walking in front of the new bureau 丨 Changyi: cracking the "gene password" of the industry deeply cultivated the blue marine economy

Editor's note:

Keep in mind that the instructions will go in front, and the mission will start a new game.

From July 4th, Lightning News Client planned to launch a series of "Walking in the New Bureau" series of melting media reports. Through graphic, short videos, live broadcasts, all -media products, etc. The spirit of the Second Party Congress, watching the "Top Ten Innovation" breakthroughs, the new progress of the "Fortune of the Top Ten Industries" and the "Top Ten Demand Demand".

Qilu.com · Lightning News July 16th In the row of standardized breeding workshops in the Guangdong Haida North Modern Ecological Aquaculture Demonstration Park in the Guangdong Haida North in Changying Town, Weifang. Here, the company's independent breeding, expansion, and breeding with "China core" South White Plack -pairing shrimp is sold throughout the country through a transport vehicle.

my country is the world's largest pairing of shrimp production and consumer countries. South White Placs is the largest seawater breeding area and the highest output of shrimp. The annual output exceeds 1.8 million tons, accounting for 40 % of the world's output. However, the source of the seed has always been monopolized by foreign countries. The price of imported shrimp is up to 3,000 yuan. my country ’s South -Whitening pairs of shrimp and shrimp rely on imports, facing the current situation and dilemma of high costs and unable to achieve multi -generation reproduction.

Fishery development and seed industry first. To master the initiative, we must cultivate good local shrimp. How to build a seed industry R & D platform? To this end, through the methods of deepening the cooperation of government, property, research and research and strengthening the construction of innovation platforms, Changyi City has worked hard on talent introduction and institute cooperation. Relying on the national aquatic genetic breeding centers of the PCP industry, and Academician Bao Zhenmin and the scientific research team of the Huanghai Institute of the Chinese Academy of Aquatic Sciences, the research and development of the South White Plants Seed shrimp varieties will be carried out to create a selection platform for shrimp varieties with independent intellectual property rights.

At present, Changyi City has built the largest and most genetic diversity of South White Plane Sports Given Resource Library in the country, breaking through a number of "card neck" technologies such as multi -tragic genome selection, standardized original shrimp expansion, and the cost of shrimp. Reduced 50%, the growth rate of shrimp seedlings increases by 15%, and the market supply of 100,000 pairs of shrimp can be achieved annually, and 100 billion shrimp seedlings can be produced. Not only that, the park has also set up an industrial development platform of "education", "complex" and "pushing". Haixing Nongchai Nursery Base sold 6 billion shrimp seedlings within half a year, which solved the problem of high -quality shrimp seedlings in the north, completely reversed the "South Miao and North Diversion", and launched the characteristic brand of high -quality shrimp seedlings in Changyi.

With advanced technology, it is necessary to promote industrial development. Previously, fishermen mostly adopted the "small weakness" model of self -cultivation seedlings, and now they adopt new models and new technologies such as "greenhouse marks" and "such as the East Shed" to build intensive and large -scale construction. A series of measures such as standardized original breeding bases. Utilizing the advantages of the Haiju Group in feed, animal protection, seedling, and breeding technical services, the park has upgraded the breeding model. The rough nourishment of the soil pond has been upgraded to a more stable and efficient warm shed hierarchical breeding model. The yield of ponds has been increased from 300 catties to more than 1,000 catties, and radiating over 100,000 acres of coarse ponds, which drives local farmers to achieve a shrimp output value of 3 billion yuan.

In recent years, Xiaying Town, Changyi City, has exerted the advantages of the seas and natural conditions. With innovation and enhancement of the "three models" as the lead, it has established a platform for research and development, and strives to break through the technical difficulties of the "card neck" of the marine seed industry. "Small seedlings" developed into large industries and rejuvenated new vitality. At present, there are 10 aquatic seedlings production enterprises, and 6 provincial -level aquatic breeding farms and genetic breeding centers have been built. The annual seedlings of seedlings, barracuda crabs, semi -slip tongue, Daling crickets, sea crickets, etc. More than 300 million yuan.

Changyi City has also continued to make efforts in the construction of the platform, attracting the construction of the "two centers" of sea shrimp seedlings and shellfish breeding seedlings. It has built a new platform and provided a new engine for high -quality seedlings breeding and promotion. Among them, the prawns breeding center that was put into production in the second half of 2020 covers an area of ​​about 300 acres, 12 seedling cultivation workshops, and the seedlings are radiated with the entire Bohai Rim region, as well as major breeding areas such as Zhejiang and Jiangsu. With 100 million yuan, the output value has changed the passive situation of unable to cultivate shrimp seedlings in the winter of Shandong, solved the problem of high -quality shrimp seedlings in the north, and completely reversed the situation of "South Miao and North Diversion".
