||Taiwan establishes several seafood safety certification marks, including HACCP, CAS, OTAP, TAP, ISO2200, and ect, within these years. Although the process on promoting those certification marks is going smoothly, most certification marks are operating in domestic. How to uniform and benchmark the conformity and connection of domestic between domestic marks and international certification marks is what we concerned. Otherwise, aquaculture production and trade has increased, but concerns have emerged regarding possible negative impacts on the environment, communities and consumers. Solutions to many of these issues have been identified and addressed. The application of certification in aquaculture is now viewed as a potential market based tool for minimising potential negative impacts and increasing societal and consumer benefits and confidence in the process of aquaculture production and marketing. Thus, WHO has published the "Thechnical Guidelines on Aquaculture Cerificatoin". At present, the aquaculture industry and market increasingly recognize that credible certification schemes have the potential to reassure buyers, retailers, consumers and civil society regarding these concerns and provide a further tool to support responsible and sustainable aquaculture. Thus, this study will collect and analysis the seafood certification marks of "Thechnical Guidelines on Aquaculture Cerificatoin, other countries and organizations, and also compares the standards between Taiwan and international regulations and guidelines. The results will not only integrate the international trend, but also establish the aquaculture certification model. And finally, provide the information regarding the certification standard and process for the conformity, benchmarking and connection of other international certification marks.
