| Abstract: | Data are presented on genetic subdivision of populations of roach Rutilus rutilus lacustris, ide Leuciscus idus, and dace L. leuciscus baicalensis living in rivers of West Siberia. These fish species have comparable levels of variation of allozyme loci and similar populational structure which well agrees with geography of the river network of the Ob-Irtysh basin. The populational differentiation is more expressed in ide than in roach and dace. |
