摘要

China's mariculture is an indispensable part of the world's aquaculture and helps address food security issues in China and around the globe. However, this industry is facing a grand challenge from global warming. Therefore, it is urgent to assess the sensitivity of the main mariculture species and production modes to the increasing temperature. Here, we first extracted the coastal temperature data from 1465 grid cells (0.25 x 0.25 arcdegree) in the mariculture regions, and then compiled an upper thermal limit as well as culturing modes dataset of forty-two commercially important mariculture species. With these two datasets, we calculated the thermal safety margin (TSM) for each species across its aquaculture regions. Our results showed that several species with low TSMs were particularly sensitive to the current conditions and future warming, and some culturing regions face catastrophic consequences caused by high temperature and potential heatwaves. It is also noted that several mariculture modes like pond farming and mudflat ranching were more vulnerable compared to other mariculture modes. In summary, China's mariculture industry is sensitive to global warming at present and in the future. Our present study also provided tools to assess the risks in mariculture production and suggested solutions for future mitigation and adaptations.
