2020 Summary of Abundance Data for Chinook Salmon (Oncorhynchus tshawytscha) in Southern British Columbia, Canada
This report includes currently available quality-controlled time series of spawner abundance for 38 Conservation Units of Chinook Salmon (Oncorhynchus tshawytscha) in Southern British Columbia, Canada. Annual estimates for individual survey sites were filtered based on data quality, infilled for missing years, and summed to produce time series for wild sites, enhanced sites, and all sites. An expert working group reviewed the time series and assessed which types of analysis each series is suitable for. This report also includes commentary on data quality and interpretation from earlier unpublished manuscripts. Exploitation rate time series from coded-wire tag indicator stocks are shown for context where available, either as direct estimates or using a nearby indicator as a proxy.
