Molluscan mariculture has become increasingly common in coastal areas of China with production accounting for ∼69% of Chinese total mariculture production. In other international locations, however, a possible underutilization of molluscan mariculture may result from hesitancy based on initial environmental impacts. This study investigated the dynamic relationship between the molluscan mariculture industry (MMI) development and environmental quality (solid waste production, total wastewater emissions, and sulfur dioxide emissions) at the meso level. Their relationship trend followed that described by the environmental Kuznets curve theory in ∼78% of the areas, and ∼89% of the areas were in a coupled coordination state in most periods. This implied that the healthy development of the MMI can reduce environmental stress. These results should help to alleviate the negative perceptions of some researchers and the public regarding mariculture operation. The findings suggest that China, given its substantial contribution to global blue growth, should further support sustainable molluscan production by developing new strategies and policies and reducing potential negative impacts of mariculture on the environment.
