Migration, Food Habits, and Predators of Yearling Coho Salmon in Whitefish River and Little Bay De Noc


James W. Peck


      Abstract.-Migration of newly planted yearling coho salmon was monitored in the Whitefish River and Little Bay de Noc with trap nets and pound nets in April-June, 19 68 - 69. Concurrently, coho and fish that were potential predators were stomach sampled. Yearling coho migrated out of the stream and through northern Little Bay de Noc within 2 months. They did not prey upon, or compete significantly for food with, native sport fishes, nor were they preyed upon extensively by the latter.
