Abstract:	本年度目標為針對我國漁獲統計資料，檢視總漁獲量、努力量與其分佈、漁獲量與其分佈、漁獲體長等方面進行資料，並用統計分析模式探討船隊漁船組成與作業漁場移轉等因素對我國印度洋鮪延繩釣漁業或船隊之漁獲能力的提升影響，並於後續單位努力漁獲量之標準化工作時，考量漁獲能力變革對於CPUE解析之影響，期標準化CPUE可以作為資源量變化趨勢之參考依據。此計畫之研究成果可提供2013年IOTC國際漁業組織進行印度洋大目鮪與黃鰭鮪進行資源評估分析工作之參考依據，對於我漁業國責任制漁業形象有正面助益。 In order to investigate the temporal changes of fishing power shown in the Taiwanese tuna longline fishery in Indian Ocean, the goal of this study is to analyze the total catch, effort and its distribution, catch distribution and length distribution of Indian bigeye and yellowfin tuna by Taiwanese longline fishery as well as GLM analysis involved with vessel effects. Besides, this study will take the effet of fishing power into consideration in the standardization of Indian bigeye and yellowfin CPUE based on the information of commercial catch and effort data. The result of this study will be expected to apply the relevant information to facilitate IOTC to fulfill the management of Indian tropical tuna.
