Component 1.4 : Biological Drivers of Productive Capacity

ON river imagenoel paul river image

Objectves :

The objectives of the Biological Drivers of Productive Capacity component are :

  • to quantify the relationship between egg survival of spawning fishes and the environmental attributes associated with flow regulation from hydroelectric activities in rivers

  • to establish how PCFH is influenced by the number of species present in a community, how this effect differs across geographic regions, and how it affects the trophic relationships within the community

  • to determine the concordance between changes in downstream thermal regimes and the consequences for fish growth and,

  • to evaluate the hydraulic and biological conditions that favour or deter the upstream passage of sturgeon at the Vianney-Legendre Fishway(Quebec), and to integrate such biological and hydraulic knowledge to serve as a model for future fish passage research on a range of species across Canada
