Aquaculture Anchor Chain News

Aquaculture, the controlled cultivation of fish, shellfish, and seaweed, is revolutionizing global food security. In 2022, aquaculture produced 126 million metric tons of seafood—52% of total global supply—with a compound annual growth rate (CAGR) of 5.8%. Yet, the industry faces a stark reality: the cost of a single mooring failure during a storm can exceed USD 2 million, often due to a single failed shackle or link.

Marine aquaculture buoy anchoring systems require a scientifically optimized solution that combines buoys, anchor chains, and mooring discs to achieve stable connections, load distribution, and corrosion resistance.

Amidst the raging winds and waves of the Norwegian fjords, or under the impact of the cold snap in southern Chile, a single broken anchor chain can cause a school of salmon worth millions of euros to escape within hours. Anchor chains are not only tools for securing cages but also a core line of defense against natural risks, safeguarding aquaculture profits. According to the 2023 White Paper on Aquaculture Facility Safety published by the Norwegian Ministry of Fisheries and Seafood (Fiskeri- og havbruksnæringen), 68% of the salmon escapes in Norway from 2018 to 2023 that were due to broken anchor chains were directly related to improper selection, with an average loss of over 1.8 million euros per incident. Statistics from the Aquaculture Stewardship Council Chile show that cage drifting caused by anchor chain corrosion in southern Chilean waters accounted for 42% of the escapes that year. As an anchor chain manufacturer, we understand that scientific anchor chain selection can reduce risk by 90%, while a poor choice can undo ten years of hard work. Drawing on real-world examples, this article provides key anchor chain selection strategies for salmon farmers in Norway and Chile.

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.
