TL;DR: A review of the latest studies on salmonid winter survival, habitat use, movement and biotic interactions as they relate to the prevailing physical and habitat conditions in rivers and streams can be found in this article.

TL;DR: In this article, a comprehensive thermal refugia management strategy was proposed to improve cold-water fish populations across North America by preserving existing thermal refugs, augmenting thermal anomalies to improve performance as refugias, and creating new thermal reugia in uniformly warm river reaches.

TL;DR: In-stream habitat enhancement is a common remedial action in rivers where degradation/lack of suitable fish habitat can be diagnosed However, post-project monitoring to assess the response of the biota to modification is rare particularly during winter.

TL;DR: In this paper, the authors investigated the impacts of dynamic ice formation on stream environments and found that the formation of anchor ice and anchor ice dams may induce significant backwater effects by increasing wetted areas (maximum 43%) and water depths (maximum 241%) and reducing water velocities (maximum 70%).

TL;DR: In this article, the authors used passive integrated transponder (PIT) tags for active tracking of fishes in shallow rivers in the presence of ice, rock, wood and water.
