This study was designed to provide information about the juvenile life history of coho salmon, Oncorhynchus kisutch, in the Tenmile Lakes in Oregon by 1) classifying scales of spawning fish and outgoing smolts (1+), 2) assessing the contribution of juvenile life history types to the returns of adults (3₂) and...
The typical coho salmon life history has been characterized by juvenile fish that spend their entire first year in freshwater habitats before migrating into estuaries as smolts. However, reports of early migrating coho fry (age 0), including migration downstream to estuarine habitats, date back to the 1960s. Until a few...
"Kokanee were originally stocked in Detroit Reservoir in 11959. This species was introduced in hopes that it would utilize pelagic zoo plankton and provide a more varied sport fishery. The trout fishery in the reservoir depends primarily on heavy plants of legal-sized rainbow trout, supplemented by stocking fingerling rainbow. As...

Artificial propagation has been a prominent part of the management of salmonids in Oregon since the late 1800s, and will continue to have an important role to play in the recovery of wild stocks of anadromous salmonids in Oregon. Hatcheries and reviews of hatchery programs have been controversial and are...
Project CROOS, Collaborative Research on Oregon Ocean Salmon, is a unique partnership of scientists and commercial fishermen that combines catch location data with stock assignments obtained from genetic micro-satellite analysis to investigate the distribution of Oregon Chinook across multiple spatial scales. Using catch data collected by collaborating Oregon troll fishermen,...

The Troll Salmon Investigation is responsible for obtaining fishery and biological data, analyzing these data, and recommending appropriate management options for the troll fishery. Proposed management options are designed to achieve the optimum use of the salmon resource on a sustained basis. Activities pursued during FY 1977 included the sampling...
