Thesis Title

Spatial variation in abundance and condition of juvenile chum salmon (Oncorhynchus keta) in response to marine factors in Southeast Alaska

Career Goals

I am interested in applying an interdisciplinary approach to developing sustainable fisheries.

Research Overview

As the most valuable commercially harvested salmon in Southeast Alaska, chum salmon are an important species to the fishing industry. Identifying biophysical indicators that affect recruitment will improve forecasts for hatchery and wild chum salmon as well as provide an ecosystem metric to refine forecasts of other salmon species in Southeast.

Two research projects, The Gulf of Alaska Integrated Research Project (GOAIERP) and Southeast Alaska Coastal Monitoring Project (SECM), sampled stations offshore and inshore Southeast Alaska collecting juvenile chum salmon and biophysical data.

Not only will we be able to determine the influence of biophysical parameters in predicting growth status of juvenile chum salmon we will also be able to understand stock-of-origin differences in juvenile chum salmon physiology between inshore and offshore marine environments. This project will generate further understanding of the mechanisms affecting growth and recruitment in the marine phase of juvenile salmon and in turn be a critical management tool for Southeast Alaska salmon fisheries.
