Habitat utilization by brook charr ( Salvelinus fontinalis) and rainbow trout ( Salmo gairdneri) in Newfoundland streams.

Abstract

Brook char occupied positions with significantly lower water velocities and more cover than similar-sized rainbow trout. Brook char showed similar microhabitat preferences in a nearby stream where they were allopatric. The extent of species segregation was largely affected by local stream morphology, specifically the availability of preferred habitat. -from Authors
