John Day Basin Spring Chinook Salmon Escapement and Productivity Monitoring; Fish Research Project Oregon, 2000-2001 Annual Report.
The four objectives of this report are: (1) Estimate annual spawner escapement and number of spring chinook salmon redds in the John Day River basin; (2) Determine sex ratio, age composition, length-at-age of spawners, and proportion of natural spawners that are hatchery origin strays; (3) Determine adequacy of historic index surveys for indexing spawner abundance and for detecting changes in spawner distribution through time; and (4) Estimate smolt-to-adult survival for spring chinook salmon emigrating from the John Day River basin.
