Table 3 
Mean number of alleles observed per locus at 14 microsatellite loci for chum salmon (Oncorhynchus keta) from 15 geographic 
areas standardized to a sample size of 911 fish per geographic area. Geographic areas, listed in Table 1, were: Japan (includes 
Korea), Russia, Western Alaska ( WAK), Yukon River (includes Arctic Canada), Central Alaska (CAK), Southeast Alaska (SeAK), 
Queen Charlotte Islands (QCI), northern British Columbia (NBC), Skeena River, Central Coast British Columbia (CBC) (includes 
Grenville Channel, Rivers Inlet, and Smith Inlet), Southern British Columbia (includes Johnstone Strait), east coast Vancouver 
Island (ECVI), west coast Vancouver Island ( WCVI), Fraser River, Washington (Wash), and North America (NA).
