Seasonal Changes in Habitat Use by Juvenile Coho Salmon (Oncorhynchus kisutch) in Oregon Coastal Streams
TL;DR: It is concluded that if spawning escapement is adequate, the production of wild coho salmon smolts in most coho Salmon spawning streams on the Oregon Coast is probably limited by the availability of adequate winter habitat.
Journal ArticleDOI
Effects of increasing winter rearing habitat on abundance of salmonids in two coastal Oregon streams
TL;DR: Numbers of coho salmon juveniles and smolts increased in the treatment streams relative to the control streams during the posttreatment period, suggesting that winter habitat was limiting abundance of all three species.
Journal ArticleDOI
Use of Hatchery Coho Salmon (Oncorhynchus kisutch) Presmolts to Rebuild Wild Populations in Oregon Coastal Streams
TL;DR: Despite similar numbers of adults per kilometre in the stocked streams and unstocked streams in the years the presmolts returned to spawn, the resulting densities of juveniles in the stock...
Journal ArticleDOI
Comparison of Three Techniques to Estimate Juvenile Coho Salmon Populations in Small Streams
TL;DR: Mark–recapture, removal, and snorkel population estimates were compared with a known number of juvenile coho salmon stocked in 18 pools in the same stream during the summer and winter to examine the effects of fish density, pool size, and habitat complexity on the percentage of the actual population estimated by the three methods.
Journal ArticleDOI
Effectiveness of selected stream improvement techniques to create suitable summer and winter rearing habitat for juvenile coho salmon oncorhynchus kisutch in oregon coastal streams
TL;DR: In this paper, the use of constructed pools by juvenile coho salmon (Oncorhynchus kisutch) during summer and winter was examined, and log, gabion, and rock structures placed across the full stream width provided good...
