Investigating the genetic stock structure of blue marlin (Makaira nigricans) in the Pacific Ocean

We evaluated the population structure of M. nigricans within the Pacific Ocean using 17 microsatellite loci and 6204 single nucleotide polymorphisms. Evidence from both types of genetic markers supported the null hypothesis of a single genetic population throughout the Pacific Ocean. This study provides insight into the current stock structure of M. nigricans and discusses the implications for fisheries management.
