Square Fish Farming Cage with 12 Grade Typhoon Resistance and 15 Years Lifespan for Aquaculture

We are the largest manufacturer of HDPE fish cages in China, collaborating with the East China Sea Fisheries Research Institute as the Chinese Academy of Sciences anti-wave cage manufacturing industry base. As Sun Yat-sen Mariner equipment manufacturing industry base, we drafted the Chinese national standard for HDPE fish cages.

Our fish cages are suitable for both sea and lake environments with a lifetime exceeding 25 years. Increasingly adopted for superior fish quality breeding.

Engineered with superior wind, current, and wave resistance using HDPE pipe material for extended durability. Designed for large capacity and high survival rates.
