An Investigation of the Potential Effects of Selective Exploitation on the Demography and Productivity of Yukon River Chinook Salmon Yukon River Chinook salmon (Oncorhynchus tshawytscha) have been targeted in large-mesh gill net fisheries for over 100 years. Recent reductions in productivity and perceptions of reduced size and earlier age at maturation have elevated concerns regarding the potential consequences of the selective exploitation of large fish. Investigations associating changes in population productivity and demography, particularly size and age composition, with overharvest and selective exploitation are common in the fisheries literature. However, most such investigations have considered long-lived species repeatedly subject to exploitation, often prior to maturation. Similar investigations concerning semelparous Pacific salmon...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
