馬加鰆屬魚類為臺灣周邊海域重要經濟魚種之一，但目前我國馬加鰆屬魚類之 漁產量遭受到許多挑戰，如過度捕撈或氣候變遷等因素，導致其漁產量呈現逐年下 滑之趨勢。據此。本研究蒐集臺灣周邊海域馬加鰆屬魚類之漁撈日誌及港口查報等 資料，藉以究明臺灣周邊海域馬加鰆屬漁業之動態，並搭配漁獲資料及多位衛星和 模式演算之不同海洋環境資料，以泛加成模式解明馬加鰆屬魚類漁況與海洋環境變 動之關係並建構合適之棲地模式。本研究相關成果將能給予未來針對該屬魚類進行 漁業管理之建議及參考。

Scomberomorus spp. is one of the important commercial genus of fish in the waters around Taiwan. However, the catch production of Scomberomorus species encounter many challenge, such as overfishing and climate change, and showing decline trends. As a results, this study collected the logbooks data and dockside observers data to investigate the variation on the fishery dynamic of Scomberomorus species. Besides, The generalized additive model was used to analyize the relationship between Scomberomorus species catch rates and oceanographic factors and developed a habitat preference model. The result of this study will offer some useful suggestions and references for Scomberomorus fishery management in the future.
