Be cool: A review of hydro-physical changes and fish responses in winter in hydropower-regulated northern streams

 

 

Winter is an ecologically challenging season for ectothermic cold-water fish in natural streams because of reduced flow and freezing.

Hydropower regulation in many northern rivers increase winter stream flow and temperatures, and reduce ice formation and surface ice cover.

From a background review of knowledge about e.g. Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) winter survival strategies, we explore responses to hydropower impacts as a basis for adaptive management, mitigating strategies, and future research.
