Xinjiang: The miracle of inland salmon farming When it comes to salmon, people often think of the magnificent seascape of the Norwegian fjords or the turbulent waves of the Chilean coast. After all, in traditional concepts, salmon is the "darling" of the ocean. However, in Xinjiang, China, a salmon farming base has miraculously emerged on this vast inland land separated from the sea by thousands of mountains and rivers. This phenomenon that breaks conventional cognition is like a stone thrown into a calm lake, arousing people's imagination of the infinite possibilities of inland aquaculture.

Longyangxia salmon: the "golden legend" in the cold water of the plateau. In the world of food, salmon is a well-known existence. It has tender and smooth meat, rich in high-quality protein and unsaturated fatty acids, and is very nutritious. Many people around the world love it. In the past, Norway, a traditional salmon farming powerhouse, dominated the global market. If we want to eat salmon, we have to rely on imports.

In the past three years, China's salmon farming industry has shown a rapid growth trend, with technological breakthroughs and industrial upgrading advancing simultaneously: Production increase: Domestic salmon production has increased from about 30,000 tons in 2021 to nearly 50,000 tons in 2023, with an average annual growth rate of more than 15%, of which Longyangxia in Qinghai and Yili in Xinjiang have made significant contributions. Technological breakthroughs: Deep-sea aquaculture equipment (such as Qingdao's "Deep Blue No. 1") has been applied on a large scale, promoting the expansion of aquaculture from nearshore to deep sea; inland Xinjiang has broken through geographical restrictions through land-based circulating water systems to achieve efficient aquaculture of cold-water fish. Market expansion: Domestic consumer demand has surged, and salmon has moved from high-end restaurants to family tables. At the same time, exports have steadily increased, and products are exported to Russia, Southeast Asia and Europe. Brand building: Regional brands such as Qinghai's "Longyangxia" and Xinjiang's "Tianyun" have gradually formed, and the full industrial chain model (from aquaculture to processing and cold chain logistics) has become increasingly perfect.

The world's first pure ammonia-powered demonstration vessel, the "Anhui", successfully completed its maiden voyage in Hefei, Anhui, marking a major breakthrough in the industrial application of ammonia fuel in the field of ships. "Ammonia Hui" was jointly developed by the Energy Research Institute of the Hefei Comprehensive National Science Center and its subsidiary Shenzhen Haixu New Energy Co., Ltd. The ship is equipped with a 200-kilowatt high-speed gas internal combustion generator set, two 100-kilowatt propulsion motors and a twin-propeller propulsion system, with a full load of 50 tons and a rated speed of 10 knots.

Souce: Chinanews China reaches milestone in ocean-going salmon farming The world's first self-propelled closed salmon farming vessel "Suhai No. 1" was delivered in Nansha, Guangzhou on June 26, 2025, marking the beginning of China's move towards a new era of deep-sea salmon farming, and heralding that China's seafood consumption market will greatly reduce its dependence on imported chilled salmon in the future.

Main Application Fields And Case Analysis of Anchor Chain As the core material of marine engineering, anchor chain plays a key role in ship mooring, marine facility fixation, emergency operation and other fields with its high strength, corrosion resistance and reliability. The following is an explanation based on real cases:

​The anchor chain plays a vital role in the navigation and mooring of ships. It is a key component connecting the anchor and the ship. We often say "the ship stops at the anchor", but in fact the anchor is only the part that grips the ground. What really bears the huge pulling force of the ship is a complete set of "anchoring system", and the anchor chain is one of the most important parts of this system.

Anchor chain is one of the important mooring equipment of ships, and it bears the important responsibility of connecting anchors and hulls and fixing ship positions. It is exposed to seawater, wind and waves and friction all year round, and is one of the parts of the ship system that is most susceptible to corrosion and mechanical wear. Scientific maintenance of anchor chains can not only extend their service life, but also affect the safety of ship mooring. This article will systematically explain how to scientifically maintain anchor chains from the aspects of common damage, maintenance methods, maintenance cycles and inspection standards of anchor chains.

Although anchor chain and mooring chain are often referred to together, they play different roles in marine engineering. The following is an analysis from the aspects of definition, use, material, structure, manufacturing process and standards:
