On December 15, 2025, the square fish raft cage with Haosail Super clean alloy netting, jointly developed by Haosail and the Dalian Academy of Marine Fisheries and Aquaculture, was officially installed offshore and put into scientific research demonstration. This has injected cutting-edge technological impetus into the construction of the “Blue Granary” for this marine powerhouse city.
The Super clean alloy netting unveiled this time is a research-grade equipment custom-built by Haosail specifically for salmon farming demonstrations. With a 1.8mm wire diameter and 30mm mesh size, it has achieved a breakthrough in the application of alloy netting for southern fish raft cages in northern China.
Three Core Advantages Redefine the Standards for Deep-Sea Aquaculture Netting
In the marine aquaculture sector, netting serves not only as the “wall of the home” but also as a “safety barrier”. Haosail Super clean alloy netting addresses numerous pain points of traditional netting with three groundbreaking advantages:
1. Clean Water Body to Safeguard Fish Health
The special alloy material inhibits marine biofouling, ensuring smooth water circulation and an oxygen-rich environment, which reduces the risk of salmon diseases. Compared with traditional netting, it significantly improves fish survival rates and growth speeds.
2. Superior Performance to Withstand Marine Challenges
Made of high-strength wire with 1000 MPa tensile strength and featuring a stable square structure, the netting can resist level-12 typhoons. Moreover, the cage supports flexible submergence for risk avoidance, building a solid protective barrier for salmon.
3. Space Efficiency to Boost Aquaculture Value
It boasts excellent three-dimensional shape retention, with an effective aquaculture volume of over 95%—a more than 30% increase compared with traditional cages—helping maximize the benefits of large-scale aquaculture.
Demonstration Leads the Future and Empowers the Upgrade of Dalian’s Marine Ranches
As a core area of China’s marine fishery industry, Dalian currently has 28 national-level marine ranch demonstration zones approved. “Deepening the development of marine ranches and building the Blue Granary” has become a key strategy for the city’s development. This cooperation project between Haosail and the Dalian Academy of Marine Fisheries and Aquaculture is not only a vivid practice of integrating scientific research with industry, but also will provide critical technical references for Dalian’s marine ranch aquaculture projects in the next five years.
News of the project’s implementation has attracted close attention from multiple domestic aquatic product R&D institutions, state-owned aquaculture enterprises and leading industry players. Industry experts noted that the application of Super clean alloy netting will drive Dalian’s marine aquaculture transformation from extensive inshore aquaculture to precision offshore and deep-sea aquaculture, providing a replicable demonstration model for the large-scale farming of cold-water fish species.
Continuous Coverage to Witness the New Aquaculture Revolution
From Weitou in Fujian to Tangshan in Hebei, and from domestic offshore and deep-sea areas to Hawaii in the United States, Haosail Super clean alloy netting has demonstrated strong adaptability and reliability in multiple aquaculture projects. Its deployment in Dalian marks an important step for Haosail to deepen its presence in the northern marine aquaculture market. Going forward, Haosail will regularly update data on netting usage, salmon growth status and scientific research progress, bringing the public closer to the charm of technology-empowered fishery.
