Title: Monitoring the Effects of Anadromous Marine-Derived Nutrients on Sockeye Salmon

Project Year and Number: 2004: 040703-A

Other Fiscal Years and Numbers for this Project: 2006: 040703, 2005: 040703, 2004: 040703

Principal Investigator (PI): Steve Honnold, Alaska Department of Fish & Game

Assisting Personnel: Switgard Duesterloh

Research Location: Kodiak Island, Alaska

Restoration Category: Monitoring

Injured Resources Addressed: Sockeye Salmon

Abstract: We propose to comprehensively examine the role of MDN in sockeye salmon nursery lake ecosystem productivity by integrating studies of nutrient cycling, primary productivity, zooplankton dynamics, and juvenile sockeye abundance and growth, within a framework of stable isotope natural abundance. The project will take advantage of previous research including relatively long-term limnological data for Karluk Lake on Kodiak Island. We will utilize detailed vertical and temporal sampling of the water column, coupled with measurements of rates of primary productivity, and fully integrated stable isotope analyses, with contemporaneous sampling in a well matched pair of salmon (Karluk) and control (Spiridon) lakes. We propose to determine the extent to which the functioning and productivity of watersheds depends on marine-nutrient inputs and how this marine-terrestrial linkage can be better detected and understood. The overall goal of this project is to provide the framework for designing monitoring projects to detect changes in marine terrestrial linkages in Gulf of Alaska sockeye watersheds.
