Population structure in the pan‐oceanic wreckfish, Polyprion americanus (Teleostei: Polyprionidae), as indicated by mtDNA variation
The wreckfish Polyprion americanus , a large [>1 m total length ( L T )] demersal teleost, is distributed globally in temperate waters, including both sides of the North and South Atlantic Oceans, the Mediterranean, the western South Pacific, and the southern Indian Ocean. Wreckfish spawn off the...

The wreckfish Polyprion americanus , a large [>1 m total length ( L T )] demersal teleost, is distributed globally in temperate waters, including both sides of the North and South Atlantic Oceans, the Mediterranean, the western South Pacific, and the southern Indian Ocean. Wreckfish spawn off the south‐eastern U.S. on an area of the Blake Plateau (the Charleston Bump) characterized by an extensive ridge having approximately 100 m relief, in 450–600 m depths. Juvenile wreckfish (<60 cm L T ) are pelagic and, in the North Atlantic, are not reported from the Blake Plateau fishing area, but occur in by‐catch and fishery landings in the eastern Atlantic. Analysis of nine restriction fragment length profiles from a PCR‐amplified fragment (∼1.5 kb) of the ND1 mitochondrial gene indicated no stock separation between eastern North Atlantic (Azores, Majorca, Madeira), and western North Atlantic (Blake Plateau) wreckfish.
