1. The purpose of this project is to measure and monitor impacts on ESA-listed populations and to estimate overall Chinook salmon stock composition in bycatch associated with the hake fisheries (including tribal and non-tribal, shoreside, and at-sea). The work is carried out by NOAA staff. 2. Fin clips collected by NOAA observers are characterized genetically allowing allocation of the mixture to source populations. 3. Written reports are produced regularly and forwarded to the NWR and interested parties. 4. The NWR is the primary management audience in facilitation of NOAA's MSA obligations to measure and monitor ESA impacts. 5. This is an ongoing project (see also Historical Salmon Genetic Stock Composition Estimates). 6. This is a stand-alone project in one sense, but is closely coordinated with stock composition studies in directed harvest as well as similar studies of historical bycatch using archival scale material. 7. There are no specific hard deadlines associated with this project. Chinook genetics bycatch in hake.
