摘要: Microsatellite DNA based analysis of the pattern genetic diversity among three coastal and five freshwater populations pikeperch Sander lucioperca in northern part Baltic Sea drainage basin indicated marked differentiation between lake populations. The Fst these population groups was as high 0.25 Rst=0.32. In general, showed higher than ones. terms distance, (Vanhankaupunginlahti, Vastanfjard Taivassalo) grouped tightly together. samples formed a looser group, which Lake Kemijarvi greater distance from southern lakes did each other. two originally established through stockings (Lakes Painio Averia) near to their source Lohjanjarvi level nearly same. Safeguarding unique S. against gene flow increasing hatchery releases using should be management priority.
