Abstract: The farming mode of yellowtail kingfish ( Seriola aureovittata ) in China tends to be mature. However, there are some problems with environmental impact and economic benefits that cannot be ignored in the sustainable farming process. This study focused on a yellowtail kingfish aquaculture company in Dalian, China, and carried out a life cycle environmental and cost assessment (LCA and LCC) study to evaluate the environmental impact and economic benefits of the yellowtail kingfish farming process. According to the LCA and LCC results, the environmental impact is significantly influenced by fossil energy consumption and feed production. Moreover, five improvement scenarios were proposed and discussed, and the results show that replacing coal and thermal power generation with wind power generation will comprehensively (scenario 5) reduce environmental impact by 82.14% and decrease costs by 24.25%. The results of this study can provide effective improvement scenarios for yellowtail kingfish aquaculture enterprises and enrich the international aquaculture LCA basic database with data support.
