Part of the research results from this project will be presented as a working paper to the WCPFC Scientific Committee (SC) and the International Scientific Committee for Tuna and Tuna-Like Species in the North Pacific Ocean (ISC). The results of this project will be provided to the domestic fishery administrations as comprehensive information on the trends of resource changes and the future directions of Regional fisheries management organizations (RFMOs). The results of this study will also provide as the best available scientific information to the domestic fishery administrations and RFMOs for the management of international fisheries resources.太平洋長鰭鮪;紅肉旗魚;單位努力漁獲量標準化;劍旗魚;資源評估;中西太平洋漁業委員會;北太平洋鮪類及似鮪類國際科學委員會;Pacific albacore;striped marlin;CPUE standardization;swordfish;stock assessment;Western and Central Pacific Fisheries Commission;International Scientific Committee for Tuna and Tuna-like Species in the North Pacific Ocean太平洋劍旗魚、太平洋長鰭鮪資源評估暨管理策略進展研析
