Usually found in the upper layers of warm water above the thermocline, but also capable of descending to rather deep water. Often migrate into near-shore waters. Occasionally form schools or smaller groups of 3 to 30 individuals, but often occur in loose aggregations over a wide area. Feed mainly on small pelagic fishes but also takes bottom-dwelling organisms. Females grow larger (Ref. 4770). Utilized fresh, canned and frozen; eaten steamed (Ref. 9987).
在溫水層上面的通常發現於溫暖水的上層, 也能夠下降到相當深的水。 時常游進近岸水域內。 偶然地形成魚群或者比較小的群體 3 到 30個個體, 但是時常出現於在一個寬的區域上的鬆散魚群中。 主要吃小型大洋性魚類也捕食底棲的生物。 生鮮使用, 罐裝及冷凍; 清蒸。 (參考文獻 9987)

Around Florida in USA, this species often moves inshore into shallow waters where females, swimming sluggishly with their dorsal fins extended and accompanied each by one or more males, may spawn near the surface in the warm season. However, spawning in offshore waters beyond the 100 fathom isobath was also reported from south of Cuba to Carolina, USA. Off southeast Florida, a 33.4 kg female may shed up to 4.8 million eggs in three batches during one spawning season.大西洋: 在熱帶與溫帶水域中大約在西北大西洋中的 40 ° N, 在東北大西洋中的 50 ° N, 在西南中的 40個 °S 在東南大西洋中的大西洋 , 與 32個 °S。 洄游至地中海,大部份以幼年的標本為依據。 高度遷移的種,1982年海事法會議的附件一.(參考文獻 26139) 一些作家承認一個全世界的種, 雨傘旗魚〔Istiophorus platypterus〕 (Shaw 1792) 但是我們跟隨為印度-太平洋的旗魚保有 雨傘旗魚〔Istiophorus platypterus〕 的用法而且為在他們之間的不同的辨認的大西洋的旗魚保有 大西洋旗魚〔Istiophorus albicans〕 的 Nakamura 1990(參考文獻 10820)。
