Core Responsibilities

Primary Functions

Design, plan, and execute complex field and laboratory research studies to assess fish population dynamics, including abundance, distribution, mortality, and recruitment.
Conduct comprehensive stock assessments using advanced statistical models to evaluate the health and status of commercially or ecologically important fish stocks.
Lead field sampling expeditions in diverse and sometimes remote environments, employing a wide range of techniques such as electrofishing, gillnetting, trawling, and hydroacoustics.
Perform detailed biological analysis of collected specimens, including age determination from hard parts (otoliths, scales), diet analysis, reproductive staging, and tissue collection for genetic or contaminant studies.
Manage, clean, and analyze large, long-term datasets using statistical software such as R, Python, or SAS, ensuring data integrity and applying appropriate analytical methods.
Author and co-author technical reports, scientific manuscripts for submission to peer-reviewed journals, and other publications to disseminate research findings to the scientific community.
Present research results and management recommendations at professional conferences, public meetings, and workshops to engage with stakeholders, collaborators, and the public.
Utilize Geographic Information Systems (GIS) to map fish distribution, analyze habitat use, and model the spatial relationships between fish populations and their environment.
Develop and manage project budgets, timelines, and deliverables, ensuring research objectives are met efficiently and within allocated resources.
Supervise, train, and mentor junior staff, technicians, and student interns in field safety protocols, sampling techniques, and data collection standards.
Operate and maintain a variety of specialized scientific equipment, including research vessels, acoustic telemetry receivers, water quality sondes, and laboratory instruments.
Conduct thorough literature reviews to stay abreast of current scientific advancements, theories, and methodologies within fisheries science and aquatic ecology.
Collaborate with an interdisciplinary team of scientists, managers, and policy-makers to integrate research findings into adaptive management and conservation strategies.
Write and contribute to grant proposals and other funding applications to secure financial support for new and ongoing research projects.
Ensure all research activities are conducted in compliance with federal and state regulations, permit requirements, and institutional animal care and use committee (IACUC) protocols.
Analyze fish movement patterns and habitat utilization through the application and interpretation of acoustic and radio telemetry data.
Evaluate the effectiveness of habitat restoration projects, fish passage facilities, or changes in fishing regulations on target fish populations.
Develop and apply population dynamics models to forecast population trends under different climate or management scenarios.
Engage with commercial and recreational fishing communities, tribal partners, and other stakeholders to gather information and communicate research outcomes.
Prepare and deliver clear and concise technical briefings to senior leadership and non-technical audiences to inform decision-making processes.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis related to fish populations and aquatic ecosystems.
Contribute to the organization's research strategy and long-term monitoring roadmap.
Collaborate with management and policy teams to translate scientific findings into actionable conservation and management recommendations.
Participate in grant writing, project planning, and inter-agency meetings to secure funding and foster collaboration.
