Researchers study blue king crab
January 23, 2012
UAF Fisheries graduate student Jennifer Stoutamore and her advisor David Tallmon (UAS) are studying the genetic population structure of blue king crab throughout their range in Alaska and Russian waters in a project funded by Alaska Sea Grant. They collected samples from southeast Alaska, the Pribilof Islands, St. Matthew Island, Little Diomede and Russia (the western Bering Sea, Sea of Okhotsk and Chaunskaya Bay), and are currently examining genetic markers to identify relatedness of the different populations.
Population genetics can be used to improve management strategies or aid in recovery efforts by identifying genetically distinct populations. For example, determining the size and location of distinct populations, how much exchange occurs among populations, and how many individuals contribute genetically to different regions are critical for assessing potential consequences of stock enhancement. Acquiring this knowledge will aid regulatory agencies and policy-makers in evaluating the need and consequences for rehabilitation of depressed blue king crab stocks through large-scale hatchery releases.
