Copper River, Alaska, Chinook Salmon Inriver Abundance Estimate 2018-2024 DATA ARCHIVE

Long-term monitoring of returning adult Chinook salmon (Oncorhynchus tshawytscha) abundance on the Copper River, AK, has been conducted using fishwheels and two-sample mark-recapture methods since 2003. This data archive is from from the 2018-2024 field seasons. The annual objective was to estimate the inriver abundance of Copper River Chinook salmon such that the estimate was within 25% of the true abundance 95% of the time. This data represents annual catch, bycatch, tagging site data, recapture site data, session data, QC check tables, CPUE, mark-recapture matrix, mark-recapture stratification tables, effort, and daily catch matrix.
