Modeling the Effects of Stream Microhabitat on Group Size and Foraging Success of Juvenile Coho Salmon.

Abstract

In 1966 coho salmon(Oncorhynchus kisutch)from the Columbia River in Washington were introduced into Michigan tributary streams of Lake Superior. Since then coho have spread throughout the Lake Superior drainage. The primary goal of this study was to quantify the effects of microhabitat on group size and foraging success of juvenile coho salmon in a natural system in northern Wisconsin.
