This fishery, in the north of China’s Yellow Sea, was certified as sustainable in 2015, the first Chinese fishery to achieve the standard. It targets the Yesso scallop (Patinopecten yessoensis), which fishermen harvest by diving and dredging.

The Yesso scallop is a cold-water bivalve mollusc species, naturally distributed in coastal, sub-Arctic areas of the Western Pacific, including Zhangzidao Island where this fishery is located. They occur in sheltered, shallow bays and inlets adjacent to rocky shores, out to a depth of 30 to 40m in more open sea areas, and are most abundant in the 4 to 10m depth range. They are mostly found on sand and firm sandy/mud substrates interspersed with rocks. 

Located off Dalian city in China, Zhangzidao Island has a rich history. Zoneco (formerly known as Zhangzidao) began in a small fishing village in 1958. It has since grown to become one of China’s leading fisheries, listed in the Shenzhen Stock Exchange Market. Today the fishery covers more than half a million hectares of ocean, recognized by the Chinese government as some of China’s cleanest marine waters. 

The fishery cooperative employs 20,000 fishers, so its sustainable status is a major milestone for the future of the local economy as well as the environment.
