Hankkeen julkinen kuvaus
Atlantic salmon are a cornerstone of culture and livelihoods in many areas but their abundance has declined markedly in recent decades. Key challenges in the management of such natural resources is determining the relative importance anthropogenic and environmental effects and identifying the significance of interactions between them. Further, governance of such natural resources is a complex exercise where cross-boundary interests between nations, regions, and communities are often involved. The ISAMA consortium succeeded in characterise ecological and genetic changes in Teno salmon stock composition over a 40 year period, and were able to demonstrate that the decrease of large, late maturing individuals over this time period is likely due to evolutionary processes. The further identified a gene controlling sea age at maturity and salmon and this information is now being used to improvement management of the Teno salmon meta-population.
