As China accelerates the construction of its “blue granary,” the country’s marine ranching industry has witnessed unprecedented growth, driven by policy support, technological innovation, and surging market demand. Amid this thriving landscape, Qingdao-based Haosail Machinery Co., Ltd. has emerged as a standout player, gaining widespread recognition for its cutting-edge marine aquaculture equipment and securing multiple high-value orders for mooring systems and super clear alloy cage netting.
China’s marine ranching sector has achieved remarkable milestones in recent years. Boasting a coastline of over 32,000 kilometers, the country has built 169 national-level marine ranches, with deep-sea aquaculture water volume reaching 56.6 million cubic meters and an annual output of 470,000 tons. In 2024 alone, China’s marine aquatic product output exceeded 37 million tons, maintaining its position as the world’s largest producer for consecutive years. Guided by the 14th Five-Year Plan, the industry is shifting from inshore to deep-sea farming, creating urgent demand for high-performance, intelligent aquaculture equipment that can withstand harsh marine conditions.
Against this backdrop, Haosail Machinery has established itself as a leader in core aquaculture equipment. Founded in 2017 and recognized as a national high-tech enterprise, the company specializes in R&D and production of deep-sea aquaculture core materials and intelligent solutions, holding over 50 patents (including more than 10 invention patents). Its flagship products—super clear alloy cage netting and mooring systems—have set global benchmarks in performance, addressing key pain points of deep-sea farming.
The super clear alloy cage netting, a self-developed core product of Haosail, boasts world-class properties such as superior seawater corrosion resistance, anti-biofouling capabilities, high tensile strength, and an extended service life. Passing third-party verification, this innovative netting material has been successfully applied in demonstration projects across China, from Tangshan in Hebei Province to Zhanjiang in Guangdong Province. Unlike traditional HDPE netting, Haosail’s alloy netting can withstand typhoons up to Category 12 and maintains structural integrity in deep-sea environments, significantly reducing maintenance costs for ranch operators.
Complementing its netting technology, Haosail’s mooring systems have also gained industry acclaim for their stability and reliability. Designed to meet international standards for deep-sea operations, these systems ensure the safe anchoring of aquaculture facilities even in exposed marine locations with strong currents and rough weather. The company’s mooring solutions have been successfully deployed in projects at depths of up to 2,065 meters in Hawaii, USA, demonstrating their global competitiveness.
Thanks to its technological advantages and proven track record, Haosail has secured numerous orders for both mooring systems and super clear alloy cage netting in China’s booming marine ranching market. These projects span key aquaculture hubs including Fujian Weitou, Zhejiang Dachen Island, Shandong Haiyang, and Guangxi Beihai, where Haosail’s equipment supports large-scale, intelligent farming operations. The company’s ability to deliver cost-effective, standardized, and durable solutions aligns perfectly with the industry’s shift toward miniaturized, low-cost, and practical deep-sea aquaculture platforms.
As China continues to invest in marine ranching modernization, Haosail Machinery is well-positioned to capitalize on the growing demand for high-quality aquaculture equipment. With its commitment to technological innovation and global market expansion—including brand chain stores along the Belt and Road routes—the company is not only contributing to China’s “blue granary” strategy but also elevating the international influence of Chinese marine aquaculture technology.
Looking ahead, Haosail’s ongoing R&D efforts, including automated feeding systems and intelligent monitoring solutions, will further enhance its competitive edge. As the marine ranching industry evolves toward deeper waters and smarter operations, Haosail Machinery is poised to remain a key partner in China’s journey to build a sustainable and high-yield “blue economy.”
