Age and Length Composition of Columbia Basin Summer Chinook Salmon at Bonneville Dam in 1991
The Stock Assessment Project of the Columbia River Inter-Tribal Fish Commission (CRITFC) is a part of the US-Canada Pacific Salmon Treaty spawning escapement monitoring program (PST 1985). A principle aim of the project is the design and development of salmon stock identification techniques to individual stocks or groups of stocks of Columbia Basin salmon originating above Bonneville Dam, located on the Columbia River at river kilometer 235. This report summarized age and length-at-age composition estimates for summer Chinook Salmon sampled at Bonneville Dam in 1991. Columbia Basin summer Chinook Salmon are defined as those Chinook Salmon passing Bonneville Dam between June 1 and July 31.
