Core Responsibilities

Primary Functions

Design and implement comprehensive fisheries research and monitoring projects to assess population dynamics, health, and life history characteristics.
Conduct extensive fieldwork in diverse aquatic environments, including streams, rivers, lakes, and estuaries, often under challenging weather and physical conditions.
Operate, maintain, and calibrate a wide range of specialized scientific equipment, such as backpack and boat electrofishing gear, acoustic telemetry systems, passive integrated transponder (PIT) tag arrays, nets, and water quality sondes.
Collect, process, and analyze biological data and samples from fish populations, including species identification, length-weight measurements, age structures (otoliths, scales), and tissue for genetic or contaminant analysis.
Perform detailed aquatic habitat assessments, including substrate characterization, riparian vegetation surveys, invertebrate sampling, and analysis of physical and chemical water quality parameters.
Utilize advanced statistical software (e.g., R, SAS) and programming languages to analyze complex datasets, model population trends, and evaluate the effectiveness of management actions.
Author detailed technical reports, scientific manuscripts for peer-reviewed publication, and comprehensive management plans that summarize research findings and provide evidence-based recommendations.
Present research results and management recommendations to diverse audiences, including scientific conferences, regulatory agencies, public meetings, and stakeholder groups.
Collaborate effectively with interdisciplinary teams of scientists, hydrologists, engineers, and policy makers on large-scale habitat restoration and conservation initiatives.
Provide expert technical guidance and review for environmental impact assessments, regulatory permits (e.g., Clean Water Act, Endangered Species Act), and mitigation plans.
Manage, query, and ensure the quality of large relational databases (e.g., using SQL) containing long-term fisheries and environmental data.
Utilize Geographic Information Systems (GIS) to map species distributions, critical habitats, and analyze spatial relationships between environmental factors and fish populations.
Conduct fish health assessments, including necropsies and disease diagnostics, to identify stressors and causes of mortality events.
Design and implement fish passage studies to evaluate the effectiveness and biological impact of culverts, fish ladders, and dam removals.
Ensure all fieldwork and data collection activities strictly adhere to established safety protocols and are conducted under the appropriate scientific collection permits.

Secondary Functions

Support project management activities, including the development of project scopes, budget tracking, and timeline management.
Contribute to the development of grant proposals to secure funding for new and ongoing research initiatives.
Supervise, train, and mentor junior biologists, seasonal technicians, and student interns, providing clear guidance on field and laboratory protocols.
Engage with public and private stakeholders, including recreational and commercial fishing groups, tribal nations, and conservation organizations, to foster collaborative management.
Develop and deliver public outreach and education programs to communicate the importance of fisheries conservation and sustainable practices.
Remain current with scientific literature, emerging research techniques, and regional conservation issues relevant to fisheries management.
