वितरण

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).

Short description

पृष्ठीय रीढ़ (सम्पूर्ण): 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 42-48; गुदा कांटा 0; ऐनल सौफट रेज़: 18 - 24. Body elongated and compressed; upper jaw produced into a robust and medium sized beak; two dorsal fins, the height of the first greater than the greatest depth, short anteriorly, taller in the middle, then becoming shorter posteriorly; pectoral fins falcate and flexible, with 18 to 22 rays; body densely covered by small, embedded scales with 1 or 2 bluntish points; back dark blue; belly silvery; membrane of first dorsal fin blue black without dark spots; flanks with about 20 bluish stripes (Ref. 55763). Blue-black above and silvery white below, with about 15 rows of cobalt-colored stripes; 1st dorsal fin dark blue; other fins dark brown, sometimes with a tinge of dark blue; anal fin bases with a tinge of silvery white.

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.
