Based on records from salmon canneries, coho in Oregon north of Cape Blanco (near Port Orford) numbered about 1.25 million adults annually 100...
This information report contains the results of a program to distribute surplus fry to streams underutilized by the natural population. It discusses the stocking and evaluation procedures, and gives the results.
We evaluated the effectiveness of using hatchery coho salmon Oncorhynchus kisutch presmolts to rebuild wild populations in Oregon coastal streams. Juvenile and adult populations were monitored in 15 stocked and 15 unstacked streams from summer 1980 until summer 1985. During the summers following the planting of presmolts, the number of...

However, reports of early migrating coho fry (age 0), including migration downstream to estuarine habitats, date back to the 1960s. Until a few...
The Ocean Salmon Management Program is responsible for obtaining fishery and biological data, analyzing these data and recommending appropriate management options for the ocean fisheries. Proposed management options are designed to achieve the optimum use of the salmon resource on a sustained basis. The ocean salmon recreational fishery is now...
The Independent Multidisciplinary Science Team (IMST) convened 19 regional leaders in salmon management and research in a workshop on Goals for Recovery of Oregon Coastal Native (OCN) Stocks on August 4-5, 1999. The main purposes of the workshop were to 1) define the concept of recovery and 2) to identify...
