Little is known about the behavior of juvenile brown trout (Salmo trutta) during winter in boreal streams. Harsh winter conditions presumably affect overwinter survival negatively in small streams, where ice may have a large effect on survival of young salmonids. The aim of this study was to examine the effect of over-head ice cover on the spatial positioning of small brown trout in a boreal stream. I hypothesized that during the day brown trout will use the middle of the stream to a greater extent in the presence of over-head ice cover than in its absence. In the absence of ice cover, trout were predicted to hold station near the shore. At night, I hypothesized that there will be little effect of ice cover on the spatial positioning of the...
