The white seabass, Atractoscion nobilis, is a commercially important member of the Sciaenidae that has experienced historic exploitation by fisheries off the coast of southern California. For the present study, we sought to determine the levels of contemporary population connectivity among localities distributed throughout the species’ range using nuclear microsatellite markers. Data from the present study have revealed three distinct genetic units of white seabass: one in the north including the Southern California Bight to Ensenada, another in the south including Punta Abreojos, and the last from within the Gulf of California.
