Summary

This chapter takes a novel ecohydraulics perspective by considering salmonid ecology during the winter, and particularly interactions with temperatures of water and, in its solid state, as ice. The relationship between winter habitat and salmonid performance is investigated as the information obtained may provide an important addition to the toolbox of both ecologists and resource managers using an ecohydraulics approach to understand and predict fish responses to hydrological and hydraulic changes taking place in winter. The ice formation process may take place within a brief period of time with growth at night and thawing during the day, thus creating a highly unstable river environment. Acclimation to winter conditions involves physiological and behavioural adaptation, which strongly affect performance and habitat selection. Suitable winter habitats for salmonids in streams and rivers are sites that allow fish to minimize energy expenditure and, at the same time, maximize protection from environmental variation and predation.
