The Coho Salmon Management Plan (ODFW 1982) identified production goals and spawner escapement goals for wild coastal coho salmon (Oncorhynchus kisutch). Because of a number of factors, including unfavorable marine survival, the production goals have never been realized and the escapement goals have seldom been achieved. Much new information is now available about the factors affecting production of coho salmon and the effects of natural weather cycles on salmon production. The interactions between freshwater and marine survival of coho salmon are of particular interest to the development of realistic production and escapement goals for wild fish. VIEW PDF [...]

Habitat use by juverli le coho salmon (Bnsorhynchus kisutch) during spring, summer, and winter was examined in Oregon coastal streams. Coho salmon fry were most abundant in backwater pools during spring. During summer, juvenile coho salmon were more abundant in pols sf alB types than they were in glides or riffles. During winter, juvenile coho salmon were most abundant in alcoves and beaver ponds. Because of the apparent strong preference for alcove and beaver pond habitat during winter and the rarity of that habitat in coastal streams, we concluded that if spawning escapement is adequate, the production of wild coho [...]
