Microhabitat use by juvenile Atlantic salmon ( Salmo salar ) sheltering during the day in summer
Daytime snorkeling surveys were conducted in the Wardsboro Branch, a tributary of the West River, Vermont, U.S.A., in July and August 1996. We documented microhabitat use by 245 juvenile Atlantic salmon (Salmo salar) sheltering (i.e., concealed beneath the stream substrate) at water temperatures ran...

Daytime snorkeling surveys were conducted in the Wardsboro Branch, a tributary of the West River, Vermont, U.S.A., in July and August 1996.
