Title: Reconstructing Sockeye Populations in the GOA over the Last Several Thousand Years

Project Year and Number: 2002: 02649

Other Fiscal Years and Numbers for this Project: 2005: 040649, 2004: 040649, 2003: 030649

Principal Investigator (PI): Dan Mann, University of Alaska Fairbanks

Assisting Personnel: Bruce Finney

Research Location: Eshamy and Solf Lakes (Prince William Sound), Upper Russian Lake (Kenai River watershed)

Restoration Category: Research

Injured Resources Addressed: Commercial Fishing , Sockeye Salmon , Subsistence

Abstract: This project will reconstruct the last 2,000 years of changes in sockeye salmon abundance in Eshamy Lake (Prince William Sound) and Upper Russian Lake (Kenai River watershed) by analyzing 15N in lake sediments. This new data will be synthesized with ongoing studies at Karluk Lake (Kodiak Island). The research question is: What is the normal variability in sockeye salmon populations in the Gulf of Alaska? This research will contribute to development of the GEM program by providing a historical perspective on present conditions and by developing new hypotheses about the climatic causes of population fluctuations in Gulf of Alaska salmon. Work at Delight and Desire lakes on the outer Kenai Peninsula coast will also be conducted, as recommended by the Trustee Council's Public Advisory Group.
