Landlocked salmon is a critically endangered species occurring in the Vuoksi watercourse. All the ancient spawning grounds in the river habitats have been destroyed mainly due to hydropower constructions. Therefore maintenance of the landlocked salmon, nowadays, depends totally on fish rearing and stockings. Restoration of the natural reproduction and life cycle of landlocked salmon is extremely important for the long-term maintenance of its biodiversity and viability which, at the same, ensures our future possibilities to exploit it as a fishing object. Goals Main goal of the project is to define the biological requirements for restoration of the natural life cycle of landlocked salmon. Impact of research Present maintenance procedures relying mainly on brood fish rearing and stocking of juveniles is covered by taxpayers money (via state budget). Therefore more efficient maintenance protocols would ease taxpayers share of the total costs. Private water owners and the authorities being responsible for stocking obligations would also benefit from better quality of stocking material. In addition, all fishermen would also benefit from maintenance of viable landlocked salmon stocks. Researcher in charge Piironen Jorma, Finnish Game and Fisheries Research Institute
