Despite the common view that conditions in winter strongly influence survival and population
size of fish, the ecology of salmonids has not been as extensively studied in winter as in …

A negative effect of hydropower on river environment includes rapid changes in flow and
habitat conditions. Any sudden flow change could force fish to move towards a refuge area …

This paper describes a case study to rehabilitate habitat for adult European grayling
(Thymallus thymallus L.) in a large river reservoir in northern Finland. A channelled river …

Radio‐tagged adult grayling Thymallus thymallus (n= 22), monitored from mid August to mid
December 1999 in the River Kuusinkijoki, Finland, shifted by the end of September (water …

We used radio telemetry to measure the habitat use and movements of 20 tagged pikeperch
(44–59 cm) in the hydropeaking Pyhäkoski Reservoir, Finland, during June 1999–2000. The …

Short-term streamflow regulation (hydropeaking) affects the ecology of regulated rivers. We
examined the longitudinal and temporal changes occurring in fish assemblages in a …

In July 2003, twenty large brown trout (Salmo trutta) were radio-tagged at Kiutaköngäs Falls
in the Oulankajoki-a river in northern Finland-on their migration to spawning areas, to …

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 …

The subject of the study was to search and test restoration measures for the most common
physical habitat degradations in Finnish rivers. Methods for constructing nursery and …
