The classification of the Atlantic blue marlin (M. nigricans) and the Indo-Pacific blue marlin (M. mazara) as separate species is under debate. Genetic data suggest, although the two groups are isolated from each other, they are both the same species, with the only genetic exchange occurring when Indo-Pacific blue marlin migrate to and ...
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.
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 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.
California laws relating to fully protected species were among the first attempts in the nation to give protection to wildlife in risk of extinction, predating even the Federal Endangered Species Act (ESA). In the decades that followed, new laws were enacted that were more flexible to the needs of growing communities and the modern world.
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
Tuna and tuna-like fishes are highly migratory, and stocks cross numerous international boundaries.ICCAT is involved in management of 30 species, including the Atlantic bluefin (Thunnus thynnus thynnus), yellowfin (T. albacares), albacore (T. alalunga) and bigeye tuna (T. obesus); from the billfishes, swordfish (Xiphias gladius), white marlin (Tetrapturus albidus), blue marlin (Makaira ...
The Commission was formed by the 15 Atlantic coast states in 1940 and chartered by the United States Congress in 1942 [1] in recognition that "fish do not adhere to political boundaries." [ 2 ] The Commission serves as a deliberative body , coordinating the conservation and management of the states shared near-shore fishery resources—marine ...
