Downstream Movements and Catches of Two Strains of Stocked Trout

Abstract
Downstream movements and angler catches of 2 strains of planted yearling rainbow trout (Salno gairdneri) were monitored for 2 yr in a small Oregon [USA] stream, Mill Creek. The Roaring River strain showed a tendency for rapid downstream movement, while the Cape Cod strain tended to remain in the planted area for a longer period and were also caught in higher numbers. As many as 37.2% of the Roaring River trout moved out of the stream, compared to a maximum of 18.2% of the Cape Cod trout.
