AquaBiota have analysed fish communities, including salmon, with eDNA and metabarcoding at ten locations. Salmon (Salmo salar) is an important fish species from a commercial as well as an ecological perspective. In several locations around the world, large efforts have been made to restore salmon habitats that have been damaged or destroyed due to human activities. The survey done by AquaBiota aims to assess the efficiency of measures taken as part of restoration efforts made in the Pite Älv river system.
Salmon (Salmo salar).
To ensure that environmental measures lead to results it is important that monitoring and assessment takes place. As part of assessing the efficiency of restoration measures in Pite älv, non-destructive sampling with eDNA was performed during autumn 2018. Salmon was found using eDNA and metabarcoding at all expected locations (six locations). In total 15 species was found at the ten locations.
