Makaira nigricans Lacepède, 1802 (Atlantic blue marlin); Makaira mazara (Jordan & Snyder, 1901) (Indo-Pacific blue marlin); Although they are traditionally listed as separate species, recent research indicates that the Atlantic blue marlin (Makaira nigricans) and Indo-Pacific blue marlin (Makaira mazara) may be parapatric populations of the same species.
Some authorities consider both species distinct. The Atlantic blue marlin (hereafter, blue marlin) feeds on a wide variety of organisms near the surface. It uses its bill to stun, injure, or kill while knifing through a school of fish or other prey, then returns to eat the injured or stunned fish. Marlin is a popular game fish. The relatively ...
There is a dispute based on the taxonomy of the sailfish, and either one or two species have been recognized. [3] [4] No differences have been found in mtDNA, morphometrics or meristics between the two supposed species and most authorities now only recognize a single species, Istiophorus platypterus, found in warmer oceans around the world.
The classification of the Indo-Pacific blue marlin (M. mazara) and the Atlantic blue marlin (M. nigricans) as separate species is under debate. [1] Genetic data suggest, although the two groups are isolated from each other, that they are both the same species, with the only genetic exchange occurring when Indo-Pacific blue marlin migrate to and ...
The blue marlin of the Atlantic and Pacific oceans are more widely pursued by sport fishermen than any other marlin species. Their wide distribution in tropical oceanic waters and seasonally into temperate zones makes them available to many anglers, and their potential to reach great sizes and spectacular fighting ability makes them a highly desired catch to some anglers.
The larger species include the Atlantic blue marlin, Makaira nigricans, which can reach 5 m (16 ft) in length and 820 kg (1,810 lb) in weight [4] and the black marlin, Istiompax indica, which can reach in excess of 5 m (16 ft) in length and 670 kg (1,480 lb) in weight.
It is dark blue on top, brown-blue laterally, silvery white underbelly; upper jaw elongated in the form of a spear; first dorsal fin greatly enlarged in the form of a sail, with many black cones, its front squared off, highest at its midpoint; pelvic fins very narrow, reaching almost to the anus; body covered with embedded scales, blunt at end ...
The Atlantic sailfish is a metallic blue fish with a large sail-like dorsal fin and a long and pointed bill-like snout. It is dark bluish-black on the upperparts and lighter on the sides (counter-shading), with about twenty bluish horizontal bars along the flanks; the underparts are silvery white. The tail fin is strongly forked.
