Genetic analyses reveal a non-panmictic genetic structure in the sablefish <i>Anoplopoma fimbria</i> in the northern Pacific

Abstract The sablefish Anoplopoma fimbria is distributed on the continental shelf of North Pacific, has a high commercial value for both fisheries and aquaculture, represents shared resource between countries in Pacific basin. In present study, we extend geographic range surveyed previous studies reexamine population’s genetic structure by integrating phylogeographic patterns mitochondrial DNA microsatellite markers. Our results contradict proposal that constitute single population throughout their distributional range. We observed signal ancient divergence mtDNA differentiates West Coast from rest sample sites, markers reveal contemporary isolation Mexican sablefish. findings show differences localities should be explored more detail to fully understand interconnectedness appears exist populations.
