本計畫擬針對我國在南太平洋區重要之鮪漁業漁獲魚種長鰭鮪，進行逐年逐步的歷史作業報表logbook及体長資料的檢視與分析，分離「非」長鰭鮪船作業船隻及可能的試驗性下鉤。也將進行我國漁獲長鰭鮪生物體長資料之時空分布與分析，求取本種具代表性之歷史體長序列。另將配合本種國際漁業管理需求，依據年齡別漁獲及其他資源分布特性，進行我國南太長鰭鮪漁獲不同區劃（如漁區等）CPUE序列之建構與標準化，並探討其趨勢與變動 This research aimed to examine the historical catch statistics and length data of the albacore tuna caught by Taiwanese tuna longliners operated in the South Pacific Ocean. We try to separate non-albacore efforts and trial set efforts from the database, and examine spatial and temporal distribution patterns of the length data, and filter out a more representative time series of southern albacore. In addition, for fulfill the needs for international fishery management of the species, an establishment and standarization of area or age-specific CPUE time series by considerations of albacore distribution patterns will be conducted, and trends and fluctuations of these series will also be discussed.
