Indo-Pacific: tropical, subtropical and temperate waters. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea (Ref. 26139). The distribution in the Pacific Ocean is unique among billfishes and tunas in that it forms a horseshoe-shaped pattern from the northwest Pacific through the eastern Pacific to the southwest Pacific (Ref. 30443). In the Indian Ocean, fish are more densely distributed in equatorial regions with higher concentrations off eastern Africa, in the western Arabian Sea, the Bay of Bengal and off northwestern Australia (Ref. 30444).

生物學特性     字彙 (例如 epibenthic)

Epipelagic and oceanic species, usually found above the thermocline. Generally inhabit cooler water than either black (Makaira indica) or blue marlin (M. mazara) (Ref. 43). Most dominant and widely distributed of all billfishes. Their abundance increases with distance from the continental shelf (Ref. 6390). Usually seen close to shore only where deep drop-offs occur (Ref. 6390). Mostly solitary, but form small schools by size during the spawning season (Ref. 9987). They are usually dispersed at considerably wide distances. Feed on fishes, crustaceans and squids. Also caught with the harpoon. The flesh is the best among billfishes for sashimi and sushi. Marketed mostly frozen, sometimes fresh (Ref. 43); also smoked and frozen (Ref. 9987). Also Ref. 9137, 9574.

表層帶與大洋性魚種,通常發現於溫水層上面。 通常居住於較冷的水域超過或黑色的 ( 立翅旗魚〔Makaira indica〕 ) 或藍色的馬林魚 ( M. mazara).(參考文獻 43) 最優勢的而且廣泛地所有青旗魚分佈了。 他們的豐度隨著離大陸棚的距離增加。 (參考文獻 6390) 通常見到接近海岸僅在深的海峭壁出現.(參考文獻 6390) 大部份獨居性, 但是在產卵季節的時候依大小形成小群魚群.(參考文獻 9987) 他們通常在非常地廣泛的距離被散佈。 捕食魚,甲殼動物與烏賊。 也用魚叉捕獲。 肉是在青旗魚之中的最好用作生魚片與壽司。 大部份在市場上銷售凍結, 有時生鮮地;(參考文獻 43) 也煙燻與冷凍的.(參考文獻 9987) 也參考文獻 9137,9574.

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

Females are indeterminate batch spawners with asynchronous oocyte development (Ref. 92477). Larvae are most abundant in the respective local early summers. The seasonal occurrence of mature females coincides with that of the larvae. The lower temperature limit in the distribution of larvae is approximately 24°C, both in the Indian and Pacific Oceans. Spawning sites are between 10°S and 30°S in Southwest Pacific and 10°S and 20°S in northeastern Indian Ocean (Ref. 6390).印度-太平洋: 熱帶的﹐亞熱帶的與溫帶的水域。 高度遷移的種,1982年海事法會議的附件一.(參考文獻 26139) 在太平洋的分布情形在青旗魚與鮪魚之中很獨特,那裡它形成一個馬蹄形的圖案從西北太平洋經過東太平洋到西南太平洋。 (參考文獻 30443) 在印度洋,魚更濃密被分佈於近赤道的具有較高的集中外海的非洲東部, 在阿拉伯海西部, 孟加拉灣與外海的澳洲西北部.(參考文獻 30444)
