About Lisa Wetzel
Lisa Wetzel is a Fisheries Biologist at the U.S. Geological Survey, where she has worked since 1991. She specializes in reconstructing fish life histories through otolith analysis and conducts research on the impact of hatchery fish on wild salmon populations.
Work at U.S. Geological Survey
Lisa Wetzel has been employed at the U.S. Geological Survey (USGS) since 1991, serving as a Fisheries Biologist. In this role, she focuses on various aspects of fish biology and ecology, contributing to the agency's mission of providing reliable scientific information about the natural resources and natural hazards that affect the nation.
Education and Expertise
Lisa Wetzel obtained her Master of Science (M.S.) degree in Fisheries from the University of Washington, where she studied from 1986 to 1993. Prior to that, she attended Western Washington University from 1984 to 1986. Her educational background provides a strong foundation for her expertise in fisheries biology, particularly in the area of otolith analysis, which she uses to reconstruct fish life histories.
Research Focus
Wetzel conducts research on the impact of hatchery fish on wild salmon populations. This research is critical for understanding the ecological dynamics between hatchery and wild fish, and it informs management practices aimed at preserving and enhancing salmon populations in their natural habitats.
Specialization in Otolith Analysis
Lisa Wetzel specializes in reconstructing fish life histories through otolith analysis. Otoliths, or ear stones, are used to determine the age and growth patterns of fish, providing valuable insights into their life cycles and environmental interactions. This technique is essential for effective fisheries management and conservation efforts.
