China boasts a coastline stretching 32.647km from north to south, with abundant fishery resources and expansive maritime territories reported that hundreds of thousands of square and round cages of various specifications are scattered throughout inland and nearshore waters. Remarkably, even in the face of harsh sea conditions, these cages remain resilient, ensuring uninterrupted fisheries production. Such resilience holds paramount importance in expanding aquaculture zones, alleviating environmental pressures, and safeguarding and managing marine fishery resources.
As of the end of 2023, China's deeper of shore aquaculture facilities span nearly 44 million m3, with a production of approximately 400,000 tons, accounting for more than 20% of marine fish aquaculture production. The structural diversity of China's deep-sea cage encompasses floating, floating rope, and metal frame variations.
Korean Style Cage
This structure was introduced from South Korea to China in November 2013. It underwent optimization and improvement based on over a decade of application in South Korea. Currently, there are over 3.000 sets of this product domestically.
The upper ring can be used as a handrail, while the bottom ring is utilized for shaping and providing buoyancy to the cages. The L-shaped supports are positioned above the water surface, allowing people to walk on them.
This design facilitates convenient routine operations and maintenance tasks (such as net replacement, cleaning, and feeding)and also enables easy observation of the aquaculture conditions within the cages. Additionally, the structure is simple and cost-effective.
Norwegian Style Cage
In 1998, China introduced the first set of deep-sea cages from Refa, a Norwegian company, marking the beginning of deep-sea cage aquaculture in the country. Currently, these cages account for over80% of the total number of deep-sea cages in China.Characterized by simple structure and excellent resistance to wind and waves, they are well-suited for aquaculture in open sea areas Moreover, they are cost-effective and widely applicable.
Platform
400-500mm large-diameter HDPE pipes can enhance the resistance to wind and waves, while provide ample buoyancy to the platform.The platform boasts a robust structure, and its pedals surface is specifically designed with anti-slip features to ensure safe pedestrian movement.This product finds a wide range of applications, including tourism and leisure, fishing, group activities, accommodation, dining, boat docking board walks and floating bridges.
Breakwater Dam
HDPE breakwater dam, characterized by its cost-effectiveness, serves as a floating barrier to defect waves and currents, ensuring the safety of aquaculture facilities.
Its applications extend to safeguarding critical coastlines, protecting coastal tourism infrastructure (including beaches), preserving leisure and sight seeing fishing spots, and providing defense for of shore drilling platforms and military installations, Additionally, it offers temporary shelter at of shore construction sites, thereby increasing operation capacity, reducing construction timelines, and optimizing project outcomes.
CHUANGRONG is a share industry and trade integrated company, established in 2005 which focused on the production of HDPE Pipes, Fittings & Valves, PPR Pipes, Fittings & Valves, PP compression fittings & Valves, and sale of Plastic Pipe Welding machines, Pipe Tools, Pipe Repair Clamp and so on.
