The maiden voyage of the "Senhai Pioneer": Ushering in a new era of deep-sea aquaculture The delivery of the "Senhai Pioneer" was like a bombshell, pressing the accelerator for China's deep-sea aquaculture. This 80,000-ton seagoing aquaculture vessel has decisively broken the saturation of nearshore cages and the reliance on the weather for food. With its innovative design and superior performance, it has become a new benchmark for the "blue granary," leading China's marine aquaculture industry from "nearshore farming" to "deep-sea grazing and fishing."

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.

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.

In the vast ocean, cage aquaculture is like a "granary on the sea", carrying the human desire for high-quality protein. However, under this seemingly calm water, a "food defense war" is quietly starting - feed waste, this seemingly insignificant problem, is like an invisible blade, piercing the hearts of farmers and threatening the balance of marine ecology.

Salmon is divided into the genus Salmon and the genus Trout, so Salmon is salmon. There are two types of Trout in the salmon family: sea trout and rainbow trout. In the consumer markets of different countries, salmon covers different types. Norwegian salmon is mainly Atlantic salmon, Finnish salmon is mainly farmed large-sized red meat rainbow trout, and American salmon is mainly Alaskan salmon.

Marine aquaculture is developing rapidly around the world, represented by Norway in Europe and Chile in South America, and is gradually developing into the deep sea. One of the main risks of this developing is the drastic changes in wind and waves at sea, which puts higher requirements on the mooring of cages. Therefore, a good anchoring system is one of the most important considerations for the layout of the deep sea fish farming.

Anchor chains are the backbone and primary load-bearing component of a cage mooring system. The entire mooring system typically consists of an anchor, chain, wire rope, buoy, and link shackles. Anchor chains play an irreplaceable role, extending far beyond simply providing connections.
