The dataset lists the diploid read lengths for nine microsatellites of 655 individuals of Coregonus fishes (Baltic and Siberian ciscoes, C. albula, C. fontanae, C. lucinensis, C. sardinella plus one C. maraena population) from 18 populations in Germany, Sweden, Finland, Poland and Russia. The nine microsatellites are BWF1, BWF2, Cisco126, Cisco157, Cisco90, Cocl23, Sfo23, Sfo8, Str73.

The dataset originates from merging previously published data from Swedish populations (Delling B, Palm S, Palkopoulou E, Prestegaard T. Genetic signs of multiple colonization events in Baltic ciscoes with radiation into sympatric spring- and autumn-spawners confined to early postglacial arrival. Ecol Evol 2014; 4(22):4346-4360.) with newly analysed data from German, Polish, Finnish and Russian populations. Because samples were analyzed on different sequencers, eight individuals were analysed on both sequencers. The systematic differences in read lengths per microsatellite between the sequencers were used to align the Swedish data to the new dataset, by adding the difference in read lengths to each sample from the Swedish data.
