Current Projects

  • Development of a medium density genetic linkage map for hatchery striped bass Morone saxatilis using microsatellite loci (in collaboration with Dr. Craig Sullivan, North Carolina State University, and Dr. Caird Rexroad, USDA National Center for Cool and Cold Water Aquaculture ).

  • Use of microsatellite markers to characterize genetic variation in native populations of C. ariakensis, determine the genetic relationship of U.S. hatchery stocks to these native populations, and provide tools for tracking unauthorized introductions of C. ariakensis into the Chesapeake Bay( P.I.'s: Dr. Jan Cordes and Dr. Dr. Kim Reece; funded by the NOAA  Chesapeake Bay Fisheries Research Grant and Cooperative Agreement Program).

  • For information on previously completed projects involving the conservation genetics of native California fishes while at the University of California, Davis, go to: http://genome-lab.ucdavis.edu/.
