| Summary: | 碩士 === 國立中山大學 === 海洋科學系研究所 === 104 === Scalloped hammerhead shark (SPL: Sphyrna lewini) is an important target species in Taiwanese costal shark fishery. The high value and demand of their fin, and K- selection’s life history, made the fish assessed as endangered species, and required urgent concern for its resource management. Non-Detriment Finding (NDF) is the key concept listed in CITES’s Resolution Conference 16.7 , which claimed that, “Export permits for specimens of species included in Appendices I and II shall be granted only when a Scientific Authority of the State of export has advised that such export will not be detrimental to the survival of the species”. This resolution made NDF becomes the essential scientific document, while the export country needs to grant the export permit of Appendices I and II species. NDF has not be studied and developed in Taiwan yet. This study take German’s NDF procedure, European and Australian’s implementation experiences, and domestic management status of Taiwan as references, to develop a NDF determination process that would be suitable for Taiwan’s situation.
Furthermore, to execute the NDF’s determination process, the study simplified the IUCN’s NDF Guidance suggested 26 indicators into 20 indicators of 7 categories, and used these indicators to establish the “NDF risk assessment method”, which is helpful for Taiwan’s government to analyze the risks of SPL, and obtain suggestions for improvement, if the NDF of the species is determined as negative. Based on the above approaches, this study found that Taiwan are facing (1) TAC’s determination, (2) Coastal regulation and (3) CCC code’s problems; especially the lack of CCC code will lead species trade pressure cannot be evaluated. These are the major issues that SPL’s NDF implementation needs to be improved in the future.
