分布 国々 | 国連食糧農業機関の区域 | エコシステム | 事件 | Point map | 導入 | Faunafri

Indo-Pacific: tropical, subtropical and temperate waters. Highly migratory species. 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).

生物学     用語集 (例 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.

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

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).
