Abstract

Seasonal movements and winter habitat use are not well described for large streamdwellingbrown trout (Salmo trutta). Movements and stream reach use by adult brown trout weredocumented in the Beaver Creek system from April 1988 through March 1990. Radio transmitterswere implanted in 22 brown trout (total lengths, 13.9–22.7 in) that were tracked up to 165 d(mean, 90 d). Long-range (4.5–12.5-mi) movements occurred in spring and fall. Brown trout wererelatively sedentary at other times, spending the summer in Beaver Creek's lower North Branch,a second-order stream, and the winter in the Peshtigo River, a fourth-order warmwater stream towhich Beaver Creek drains. Portions of a system that do not hold brown trout in the summer maybe important winter areas. The results verify the importance of barrier-free streams and suggestthe importance of a drainage system approach to brown trout management.
