*After excluding two outlier SNPs and three mitochondrial SNPs (see text for details). n, sample size; A_R, allelic richness or number of alleles corrected for a minimum sample size of 76 diploid individuals; H_E, unbiased expected heterozygosity; HWE, goodness-of-fit to Hardy-Weinberg Equilibrium expectations. ^§E = early migrants; L = late migrants. ^†MBEA = mainland beach; IBEA = island beach; TRIB = tributary. ^‡Historical dates of peak spawning activity.
