Population Genetic Structure of the Armorhead, Pseudopentaceros wheeleri, in the North Pacific Ocean: Application of the Polymerase Chain Reaction to Fisheries problems
Armorhead (Pseudopentaceros wheeleri) occur in the subarctic, epipelagic habitats of the northern Pacific Ocean and are known to reproduce on seamounts in the central Pacific. Over the last few decades, overexploitation of seamount populations led to dramatic declines in abundances of reproductive p...
