Listing of Pacific Coast Spawning Streams and Hatcheries Producing Chinook and Coho Salmon with Estimates on Numbers of Spawners and Data on Hatchery Releases

摘要

Information on chinook, Oncorhynchus tshawytscha, and coho, O. kisutch, salmon spawning streams and hatcheries along the west coast of North America was compiled following extensive consultations with fishery managers and biologists and thorough review of published and unpublished information. Included are a listing of all spawning streams known as of 1984-85, estimates of the annual number of spawners observed in the streams, and data on the annual production of juvenile chinook and coho salmon at all hatcheries. The total number of spawners is estimated at 1,258,135. In 1984-85, a total of 314,010,000 chinook and 137,320,000 coho were released by these facilities.
