Kimberly Larsen
(She/her)Kim is a Fish Biologist at the Western Fisheries Research Center.
Research Interests:
Otolith Research Coordinator: In this position I oversee all research projects regarding scale analysis and analysis of otolith microstructure and microchemistry focusing on the population ecology of fishes within the Pacific NW. Otoliths and scales have been used as research tools for understanding various life histories and habitat importance as they relate to the protection, preservation, and restoration of those habitats. Research techniques include: collection and preservation of specimens from both natural habitats and culture based environments, otolith preparation and analysis of age, thermal marks, daily increment patterns and microchemistry, and scale preparation and analysis of age and spawning all aided by computerized imaging. These techniques have been employed on several projects: thermal marking for stock identification of steelhead trout as part of a hatchery supplementation study in Idaho streams, identification of unique microstructural patterns related to life history events and estuarine residence and growth in wild Chinook salmon of the Skagit, Nisqually, Snohomish, and Elwha rivers, WA state, the pioneering of in depth microstructural pattern analysis related to developmental events in larval salmonids, migration and rearing histories of salmonids determined by ion microprobe and Inductively Coupled Plasma Mass Spectometry (ICPMS), and the life history investigation of whitefish and non-native west coast American Shad of the Columbia River, WA.
Ecological Researcher: I work as a member of a team of multi-disciplined personnel investigating the population ecology of Pacific NW fishes. We conduct field and laboratory experiments concerned with population genetics, hatchery supplementation, habitat utilization, and life history documentation.

Extended abstracts from the Coastal Habitats in Puget Sound (CHIPS) 2006 Workshop
Puget Sound is the second largest estuary in the United States. Its unique geology, climate, and nutrient-rich waters produce and sustain biologically productive coastal habitats. These same natural characteristics also contribute to a high quality of life that has led to a significant growth in human population and associated development. This population growth, and the accompanying rural and urbPre-Restoration Habitat Use by Chinook Salmon in the Nisqually Estuary Using Otolith Analysis: An Additional Year
The Nisqually Fall Chinook population is one of 27 stocks in the Puget Sound evolutionarily significant unit listed as threatened under the Federal Endangered Species Act (ESA). Preservation and extensive restoration of the Nisqually delta ecosystem is currently taking place to assist in recovery of the stock as juvenile Fall Chinook salmon are dependent upon the estuary.

INTRODUCTION The Nisqually Fall Chinook population is one of 27 stocks in the Puget Sound evolutionarily significant unit listed as threatened under the federal Endangered Species Act (ESA).

Otoliths are hard structures located in the brain cavity of fish. These structures are formed by a buildup of calcium carbonate within a gelatinous matrix that produces light and dark bands similar to the growth rings in trees. The width of the bands corresponds to environmental factors such as temperature and food availability. As juvenile salmon encounter different environments in their migratioAuthorsK. Larsen, R.

INTRODUCTION The Nisqually Fall Chinook population is one of 27 stocks in the Puget Sound evolutionarily significant unit listed as threatened under the federal Endangered Species Act. The preservation of the Nisqually delta ecosystem coupled with extensive restoration of approximately 1,000 acres of diked estuarine habitat is identified as the highest priority action for the recovery of naturaAuthorsAngela Lind-Null, Kimberly Larsen, Reginald ReisenbichlerAnalysis of otolith microstructure for Cedar River Chinook salmon
