本次研習目的為與西南漁業科學中心Dr. Heidi Dewar探討 (1) 利用彈脫型衛星標 識紀錄器解析翻車魨水平、垂直移動行為與環境特徵關係 (2) 翻車魨攝食行為與食 性階層探討。本次研習共分為兩部分，第一部分為翻車魨胃內含物分析研習 – 研 習翻車魨胃內含物種類組成，探討翻車魨的營養階層，解析北太平洋海域翻車魨的 營養位階動態與食性研究。第二部分為翻車魨移動行為特徵與海洋環境因子解析研 習，利用海洋資料庫，將翻車魨水平與垂直移動距離與海洋環境因子的變動作結合 ，並利用R軟體，解析翻車魨的移動與海水表水溫、海水表面鹽度、海水表面高度、 混合層深度與基礎生產力 (以葉綠素甲chlorophylla 的濃度為指標)進行結合，解 析海水環境因子變動如何影響翻車魨移動與棲地利用行為。此外，此次研習也在第 69屆國際鮪類研討會進行海報發表，發表題目為臺灣東部海域矛尾翻車魨攝食行為 研究。

Aims of the project are to study (1) the vertical, horizontal movements and the relation to environmental features of sunfish; (2) feeding ecology of sunfish with Dr. Heidi Dewar in Southwest Fisheries Science Center. The goals of research had two parts that one was to study the stomach content analysis of sunfish to explore its feeding habits and another was to study the movement patterns of sunfish and connecting the behavior to environmental factors (sea surface temperature, sea surface salinity, sea surface height, mixed layer depth, and chlorophyll a) by using software ocean data view and R. In addition, the sunfish research project was published on the 69 thTuna Conference, the presentation title was “Seasonal and size variations in feeding habits of sharp-tail mola, Masturus lanceolatus in eastern Taiwan”.
