Core Responsibilities

Primary Functions

Assist senior staff and biologists with the field sampling of fish and invertebrate populations using a diverse range of gear, including electrofishing equipment, seines, gillnets, and fyke nets.
Conduct routine maintenance, calibration, and troubleshooting of scientific field and lab equipment, such as water quality meters, flow meters, and digital scales, to ensure data accuracy.
Operate small to medium-sized watercraft, including motorized boats and skiffs, safely and proficiently in various weather and water conditions for research and monitoring missions.
Accurately collect, record, and meticulously enter biological data, including fish length, weight, age structures (scales, otoliths), and species identification, into established databases.
Perform daily fish culture duties within a hatchery environment, which includes executing feeding schedules, cleaning tanks and raceways, monitoring fish health, and managing water quality.
Participate actively in fish stocking operations, involving the careful handling, transport, and release of fish into designated lakes, rivers, and streams according to management plans.
Assist with the construction, deployment, maintenance, and repair of fish traps, weirs, passive integrated transponder (PIT) tag antenna arrays, and other passive capture technologies.
Conduct creel surveys and angler interviews at boat ramps and shorelines to gather crucial data on recreational fishing effort, catch rates, species targeted, and angler satisfaction.
Process a variety of biological samples in a laboratory setting, which may include mounting and aging fish scales, dissecting fish for diet or gonad analysis, and preparing tissue for genetic studies.
Maintain detailed, organized, and legible field notes, vehicle logs, and data sheets in strict accordance with established scientific protocols and data collection standards.
Monitor, record, and manage critical water quality parameters such as dissolved oxygen, temperature, pH, and ammonia levels in both aquaculture systems and natural water bodies.
Support habitat assessment and restoration projects, which can include conducting stream surveys, planting riparian vegetation, and removing invasive aquatic species.
Perform general and preventative maintenance on facilities, vehicles, boats, and trailers to ensure all equipment is safe, operational, and ready for deployment.
Enter, proofread, and perform rigorous quality assurance/quality control checks on large datasets to identify errors and ensure the highest level of data integrity.
Systematically sort, identify, and enumerate fish, shellfish, and other aquatic organisms collected during sampling events, often requiring keen attention to detail.
Assist with the tagging and tracking of fish for movement and survival studies, using methods such as Floy tags, PIT tags, or radio telemetry equipment.
Safely operate and trailer boats and other heavy equipment over long distances on public highways and unimproved roads to access remote field sites.
Perform routine biosecurity procedures, such as disinfecting waders and equipment, to prevent the spread of aquatic diseases and invasive species between different water bodies.
Compile and summarize data for inclusion in technical reports, annual summaries, presentations, and internal communications.
Work effectively in remote field locations for extended periods, which may involve camping, hiking over rough terrain, and functioning efficiently in challenging environmental conditions.

Secondary Functions

Support ad-hoc data requests and contribute to exploratory data analysis under the guidance of senior biologists.
Contribute to public outreach events and educational programs, sharing information about local fisheries and conservation efforts with stakeholders and the general public.
Collaborate with inter-agency partners, private landowners, and conservation groups on shared resource management objectives and field projects.
Participate in all mandatory safety briefings and strictly adhere to established health and safety protocols for fieldwork, boating, and laboratory operations.
