Editor's note:

    Aquatic products are important agricultural products and important sources of high-quality animal protein. China is a big country in aquaculture. In recent years, by vigorously developing ecological health aquaculture, and continuously improving the level of aquaculture facilities and equipment, the production of facilities aquaculture in our country has accounted for more than 50%.

    A few days ago, the first modern facility agriculture construction plan jointly issued by four ministries and commissions is clear, and the construction of modern facility fisheries based on ecological health aquaculture is established. All localities are continuously accelerating the transformation of the spatial pattern, industrial structure and production mode of fishery development, so that more high-quality fresh aquatic products can "swim" to thousands of households. What are the new highlights in the development of facility fisheries, and how to continue to upgrade them in the future? Our reporter investigated in many places.

    We will improve the efficiency of farming, the production of factory factories and the revitalization of aquaculture

   In Qingdao Qicai Seed Technology Co., Ltd, there are a variety of different sizes of the breeding pool, and more than 7,000  murray cod parent fish are swimming in the pool.

    "The largest parent fish here is more than 50 pounds! Our farming efficiency is 100 times the size of a regular pond, and an acre of land can be produced by the output of 100 mu of land." Said the company's leader, Gong Qingli.

    In recent years, the development of industrial aquaculture in our country has been developing rapidly, and the water body has reached more than 100 million cubic meters by 2022, which is about 40 percent higher than in 2016. We will provide strong support for the breeding of quality water products and the production of the modern factory, and provide strong support for the breeding of quality water products.

    Murray cod is rich in nutrition and economic value, but it is rare and sensitive to water quality. Using the factory model, Laixi has implemented it in the breeding of murray cod, the technology of the facility has been transformed from "bookshelf" to "shelf life". At present, the whole cycle of "spawning, incubation, forming" is realized in a park. A 30-cubic meter pool of farms produces 5,000 kg of murray cod a year, producing a value of 500,000 yuan. The tail water is successively transported to the crop wisdom greenhouse, rice field and dry field for terraced utilization,  realizing the full efficiency utilization of water resources.

    "The construction and intensive farming is a systematic project." Bao Zhenmin, a professor at the College of Marine Life of Ocean University of China, said that starting from scientific and technological innovation, the future needs to carry out joint research on breeding technology, equipment design and manufacturing, pay attention to basic research and database construction, and strengthen the adaptation of breeding facilities and equipment to the living habits and behaviors of aquatic animals. Strengthen the research and development of intelligent technology in aquaculture facilities to achieve leapfrog development of aquaculture equipment.
