The first commercial-scale cage in China's massive offshore salmon farm project has been commissioned and is set for installation and stocking with 30,000 Atlantic salmon smolt in its new site 60 kilometers off the east coast of China, the company behind the project told IntraFish.

Neptune Blue Ocean Development began construction of the so-called "Sea Treasure Cage" in Zhoushan, Zhejiang in June last year and in December it was finished and towed up the coast to Weihai where it was commissioned for use in Haien Blue Ocean Aquaculture's farm project.
