Alaska Department of Fish & Game Mark, Tag and Age Laboratory Support

The Thermal Mark Laboratory at the ADF&G Mark, Tag and Age (MTA) Laboratory is responsible for examining sockeye salmon otoliths recovered from commercial fisheries in southeast Alaska for thermal marks indicating hatchery origin, and for making the associated data available to biologists for management of sockeye from the transboundary Taku and Stikine Rivers. Historically, much of this recovery effort has been federally funded as part of the Pacific Salmon Treaty grant, but since 2014, cuts to the federal PST grant resulted in our turning to the Northern Fund for support.
