Assess Atlantic salmon recruitment before restoring the river process

The goal of this project is to characterize the reproduction success of Atlantic salmon on Escoumins River with electric fishing to understand the species recruitment before restoring the natural processes of the river. This evaluation will be an initial threshold to evaluate the impact of restoration on the number of juveniles. The drive has altered the natural course of the river. Linearization of some areas changed its sediment dynamics. A large-scale habitat restoration project is underway in partnership with Dr Maxime Boivin of UQAC. He attempts to restore some processes to reestablish a more natural sediment dynamics and more conducive to Atlantic salmon. The physical characterization phase will be completed with a master’s project (drafting) and an additional analysis on our part (drafting). Preliminary data show a low presence of fine substrate conducive to spawning.
