China's marine fisheries are extremely rich, with fish, big yellow fish, small yellow fish, ink fish being the economic fish of china's four largest seas. What is the next “most valuable” fish? The fishing industry is looking up and down。
“china's aquaculture industry is looking for the next `most valuable' fish, and rainbow trout is currently a species identified by most.” the head of the scientific research department of the institute of fisheries machinery and instruments of the china institute of aquaculture sciences (hereinafter referred to as “fio”) and the chief research fellow of the deep-sea facilities large-specific plant plant industry chain-classing project told the east watch weekly。
The china fisheries statistics yearbook, 2023 (hereinafter referred to as “the yearbook”), shows that, at 2022 prices, the total value of the economy in the fisheries sector as a whole was rmb 30,87,314 million, including rmb 15,266,749 million for fisheries, rmb 66,217 million for fisheries industry and construction, and rmb 89,848 million for fish circulation and services. Fisheries have formed an industrial chain of over $3 trillion。

"this is the best rainbow trout i've tasted in recent years." liu xian comment. In xinjiang organic agriculture company ltd. (hereinafter referred to as "the xinjiang ocean") canteens, a table of good food is based on rainbow trout, and fish skins, fish bones, fishballs, fish meats and fish herbs are cooked into cuisine. “they are too well decomposition of commercial fish products, which will greatly increase the profitability of enterprises.”
In september 2023, xinjiang “seafood” suddenly went on fire, with white-to-shrimps, salmon, crabs ... Xinjiang “seafood” harvested and sold to national and even overseas markets. In the early days of xinjiang's production, fishing aircraft cooperated with them on mechanical equipment such as feed feed。
In the 1970s, the xinjiang plough river basin began raising rainbow trout, which has now been growing for more than 40 years. Rainbow trout growth is extremely harsh for the water environment, requiring good water quality, high soluble oxygen and cold water temperature between 12 and 21°c. For example, during high summer water temperatures, farmers have to deal with the resulting decline in fish appetites and early sexual maturity. Xinjiang lays in nilek county, in xinjiang ishaq autonomous oblast, where hot springs and water stations are well-quality, cold and abundant。
Salmon is a trade name and the subject is called salmon. It is a generic name for several species of salmon in irradiated fin fisheries. In the chinese consumer market, atlantic salmon is most commonly imported from the nordic countries, while the species raised in xinjiang are three times the species of rainbow trout in pacific salmon。
“the greatest difference between rainbow trout and atlantic salmon farming is that the former can be completed in fresh water for the entire commodity cycle, while the latter needs to complete the last stage of fertilization in salt water. As migratory fish, the requirements for the whole growth process are different." liu xian says。
And look at the sky, and above the clouds is the mount of heaven. Hot and cold, dry and wet gathers at the foot of mount tian. This is where cold-water fish are rarely suitable for farming in china, and snow melts on the tianshan ensure that local water sources remain below 20 degrees celsius。
As a result, a cluster of 22 groups of cold-water salmon, located in the “china hot pole” trump basin, which is at a temperature of 75°c in the summer, have also been successfully farmed。
The fisheries farm base, located on the side of the red star canal, covers 25 acres and consists of 52 standardized farmed ponds. Overlooking the whole farm, the round, standardized fish ponds are arranged in such a way that they are particularly visible in the surrounding khakis。
Red canals gather in the snow and ice, and the big river rises to the north to collect water from the red canals. The fishing grounds in the two or two groups of facilities are located more than 10 kilometres from the estuary, with sedimentary ponds set up downstream of the farm, which are filtered with water and then returned to the canal for recycling。
On 20 april 2024, nortic fisheries (ningbo) ltd., a wholly owned norwegian company, nordic aqua partners a/s, announced its first fish release, which was visible in the chinese wholesale market for salmon。
The salmon-farming vent has risen in the chinese market。
Focus industrial chain
The high-quality merchandise fish industry chain typically consists of three components: upper, middle and downstream. Upstream includes seedling breeding, feed processing, facility equipment, and midstream includes commercial fish farming, primary fish processing, etc., and downstream includes precision processing, cold chain logistics, marketing, etc。
At present, as a national scientific research institute specialized in equipment research for fishing facilities, the chinese institute of aquaculture science's fisheries machinery institute is involved not only in upstream and mid-stream industries, but also in further radiationing downstream industries。
In 2023, three species of rainbow trout, plaster and yellowfish were targeted by fishing aircraft as breakthrough targets for the next stage of farming research. “we came to xinjiang to look for partners to cultivate rainbow trout seedlings, to be placed on deep-sea farming platforms through land and sea relays, and ultimately to improve the quality and weight of commodities.” liu xian told the east watch weekly。
A breeding complex of 64. 5 metres long and 17 metres wide, located more than 10 kilometres from the east coast, was secured by eight anchor chains at sea level. By the evening, the orange twilight lined up on the grey blue sea, and the waves swung and the red blue hull was like a painting。

The chief scientist of the team of deep-seated marine breeders for science, technology and innovation and master designer choi choi, nishin 1, began in 2018 and has been exploring the issue of what to do with the far-reaching industrialization of the sea. In may 2022, the world's first 100,000-ton-class smart fishing vessel, the national letter 1, was launched by a fishing aircraft and its product, the deep sea large yellowfish, has been commercially produced in bulk。
Following the delivery of the n. O. I. 1 commercial fish stocks, m. O. T., ltd., learned from its experience in terms of production, quality, mechanical improvements, cost-benefits, etc., from the correspondence between the aircraft and the state, is expected to further improve the integrated benefits of the enterprise. “the ninde fish crop production window period is only two seasons per year, from april to june and from november to december, after we had to optimize the stock of fish seedlings under a production plan that could be recycled throughout the year. Second, in actual production, it was found that the rate of loss of large-size seedlings was too high。

In recent years, problems such as the deterioration of the coastal environment and poor breeding processes, which have resulted in poor quality of seedlings, the prevalence of drug defects, large body sizes, gland development and carrying of pathogens, have posed major risks to efficient farming production. Large-specified seedlings are important for reducing the farming cycle and increasing farm productivity and efficiency。
In 2021, with the support of the intergovernmental scientific and technological innovation cooperation project of the national priority research and development programme, which focuses on the technical cooperation project “technology research for water fish cirquealing smart feeding equipment”, the project's chief researcher led the team to break down the techniques of automatic bait feeding, bottom auto-sorption and incubation image recognition in the development of seawater fish seedlings, and to innovate in the development of an automated seeding equipment, the construction of an environmentally controlled marine fish circulation system and the stabilization of the production and recycling of seawater fish seedlings。
The results of the project are based on the selection of the new products of the new fishery technology of the national aquatic technology promotion station and the china aquaculture institute, which were newly equipped with scientific and technological excellence in the year 2023。
“agriculture requires a dedicated and continuous effort in order to master scientific production patterns and constantly improve production efficiency.” liu wan says. In recent years, he has led a scientific and technical team to target the small-scale supply industry of large-scale seedlings, tackle efficient expansion techniques for seedlings, improve intermediate breeding processes, and address the large-scale supply of large-scale seedlings with a view to unleashing far-reaching agricultural capacity and promoting sustainable industrial development。
Following the increase in temperature in july, fishing aircraft will find it difficult to carry out a pilot study of a group of fish seedlings on an integrated testing platform off the coast of shandong。

Strengthening science, technology and innovation
According to the yearbook, in 2022 the value of marine fishing in fisheries was $24,8891 million, the value of seawater farming was $46,384. 4 million, the value of freshwater fishing was $27,670 million and the value of freshwater farming was 78,6303 million, and the value of aquaculture seed production was $84,345 million. “aquatic seedlings are a weak link in the country's aquaculture industry's industrial chain, particularly in the area of high-quality seawater fish seedlings, and are more dependent on imports.” liu qian。
On 1 november 2022, 1. 6 million salmon eggs arrived from denmark in xinjiang, hatched in the breeding centres of xinjiang, and one year later, in mid-autumn, they reached the table of the entire population. It is known that almost all domestic salmon eggs are currently raised from three times the body of rainbow trout in denmark。
Triple rainbow trout has the advantage of growing at a much faster rate than normal species, while they are unable to reproduce their offspring, thus significantly reducing biological pollution of the natural environment. “there are also scientific studies on the eggs of three times the size of rainbow trout in the country, with bottlenecks that can reach only about 90% of us, and more than 99% abroad.”。
In july 2023, four people in the same row, choo-chou and liu xian, visited norway, the global pole of aquaculture。
Local selected and fertilized eggs for atlantic salmon are generally produced by professional breeding enterprises, which have the world's leading suppliers of eggs for atlantic salmon; fish flour, which has been declining steadily in feed nutrition, has reached 77 per cent of plant composition in 2018; and juvenile fish breeding, which is mainly done in cycling water workshops at land-based plants, with 250-1,000 grams of large-scale seed production becoming more common, with approximately 21 per cent of norwegian atlantic salmon-specific seed production in 2022. Industrial chains are being refined, mature production costs are being reduced and industrial profits are increasing。
Major enterprises, depending on their advantages, participate in the chain of fisheries. Among them, the “national letter ship” has successfully cooperated with the n. N. 1 great yellowfish project, while the research and development design of the atlantic salmon ship has been developed and evaluated。
There is a powerful heat current in the north-west pacific, the black-tide current, which flows from the philippines sea to the north-east along the japanese trenches, forming high-quality natural fisheries of constant water temperature and stability in four countries and kyushu in southern japan.” this is the natural advantage that makes china's fisheries the most enviable, and we are upgrading the overall industrial advantage through a combination of scientific research, manufacturing, and geographical diversity, to make up for high-quality fishing grounds。
Rainbow trout, plagiarfish, big yellowfish, tuna, yellow barbs, high-value fish species, among them, which are currently high-value commercial species in china's fisheries, who chooses the freckle screen as the next “most valuable” fish, and the markets, businesses, and scientific institutions are all “touching”.
