生物学特性     字汇 (例如 epibenthic)

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).

在温水层上面的通常发现于温暖水的上层, 也能够下降到相当深的水。 时常游进近岸水域内。 偶然地形成鱼群或者比较小的群体 3 到 30个个体, 但是时常出现于在一个宽的区域上的松散鱼群中。 主要吃小型大洋性鱼类也捕食底栖的生物。 生鲜使用, 罐装及冷冻; 清蒸。 (参考文献 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)。
