In the last few decades, numerous populations of European grayling,Thymallus thymallus, have been suffering fromstocking-induced genetic admixture of foreign strains into wild populations. Concordantly,genetic introgression was also reportedfor grayling stocks inhabiting the Upper DravaRiver, but all published genetic data based on specimens caught at least a decade ago,when stocking load was strong. Here, we applied mitochondrial control region sequencingand nuclear microsatellite genotyping to Upper Drava grayling fry collections andreference samples to update patterns and extent of human-mediated introgression. Incontrast to previous data, we highlighted an almost genetic integrity of Drava grayling,evidencing limited genetic signatures of trans-basin stocking for grayling of NorthernAlpine Danubian origin. Recent hybridisation was detected only twice among sixty-ninesamples, while several cases of later-generation hybrids were disclosed by linkingmitochondrial sequence to nuclear genetic data. The observed past, but very limited recentgenetic introgression in grayling from Upper Drava seems to reflect shifting stockingtrends, changing from massive introduction of trans-basin fish to moreconservation-oriented strategies during the last 27 years. In a conservation context, weencourage pursuing the use of local wild grayling for supportive- and captive-breeding,but underline the need for genetic approaches in brood-stock selection programs. Finally,our integrated results from sibship reconstruction validate our strictly fry-basedsampling scheme, thus offering a reasonable alternative also for other rheophilic fishspecies with similar life-history characteristics
