The wreckfish Polyprion americanus is a long-living pelagic fish with a demersal adult phase that shows an antitropical distribution. In the eastern Atlantic, juvenile and adult wreckfish are found off the Norwegian coast along shallow portions of the Mid-Atlantic ridge and associated islands (Macaronesian Islands), and along northern and southern Africa including the Mediterranean. This species is a component of directed and admixed species fisheries throughout its range and has recently been focused for its large aquaculture potential: adults reach 100cm in length, show low natural mortality rates and a large longevity. Therefore it is one of the most promising species for aquaculture and consequently it has recently been brought to Galician hatcheries for taming. These good priors for aquaculture are however devoid of useful information on its whole life cycle, taxonomic classification and genetic status. It is well known that domestication and management of hatchery stocks ...
