The objective of the Coastal Chinook Research and Monitoring Program (CCRMP) is to produce non-biased escapement estimates of Chinook Salmon with measured precision for Pacific Salmon (PST) harvest management purposes. Our efforts help fulfill Oregon’s commitment to the PST and estimate run sizes to provide accurate information to fisheries managers and anglers. We conduct research to generate more precise estimates of coastal harvest and spawner abundance, understand in-river straying, and document how changing regulations impact harvest across basins coastwide.
