Zhoushan, an island city in Zhejiang has upgraded its fishery industry in recent years and in the process transformed its abundant marine resources.

To ensure the sustainable development of fishery, the city resorted to the propagation and releasing of fish fries, and constructed artificial fish reefs to increase fish population. It also focused on research and development of aquatic products to improve the utilization of fishery resources.
