Outline of Final Research Achievements	In this study, first, we estimated the possibility of inappropriate use of antimicrobial agents through the Item count technique analysis based on a questionnaire survey for shrimp farmers. In Sri Lanka, the possibility of inappropriate use of antimicrobial agents due to lack of knowledge and deliberate use was estimated. In Taiwan, it was estimated that there was a possibility of deliberate inappropriate use of antimicrobial agents. Second, with a focus on scientific shrimp farming management in Taiwan, we analyzed the effects that shrimp farmers expect from appropriate shrimp farming management using a questionnaire using the Best-worst scaling method. As a result of the analysis, shrimp farmers expected the effects of creating a good aquaculture environment that takes into account the health of the shrimp and the health of the shrimp, rather than the economic factors of increasing income and reducing costs.

Academic Significance and Societal Importance of the Research Achievements	エビ養殖における疾病の蔓延、人や動物に抗菌剤が効かなくなる薬剤耐性等が社会問題となっている。しかし、養殖業者は医薬品の不適切な使用を表明しにくく、エビ養殖の実態が見えにくい。従って、本研究でエビ養殖業者の抗菌剤への不適正使用の存在を推察したことに社会的意義がある。また、医薬品の使用を含め適切なエビの養殖管理に対して、養殖業者が期待する効果が不透明である。本研究で養殖業者が期待する効果を明らかにしたことで、適切なエビの養殖管理を遵守させるために、養殖業者に広く認知・アピールできる材料が提示できた。適切な養殖管理による養殖エビの安全・安心の確保に寄与する研究として社会的意義がある。
