本研究將進行台灣延繩釣漁業之印度洋紅肉旗魚與黑皮旗魚CPUE標準化分析，根據IOTC此兩種旗魚漁獲統計資料之可得性，本研究將採用適當之資源評估分析方法進行印度洋紅肉旗魚與黑皮旗魚之資源評估。此外，本計畫也將持續進行台灣南方黑鮪之CPUE標準化分析以及年齡別之CPUE變動趨勢分析。 This study will proceed to conduct the CPUE standardization for the striped marlin and blue marlin caught by Taiwanese longline fishery operated in the Indian Ocean. Based on the data availability of these two billfishes from IOTC, this study will adopt appropriate stock assessment approach to conduct the stock assessments for striped marlin and blue marlin in the Indian Ocean. In addition, this study will continue to standardize the CPUE of the southern bluefin tuna caught by Taiwanese longline fishery and analyze the trend of age-specific CPUE.
