Pacific States Marine Fisheries Commission is seeking a highly motivated and passionate individual to assist with monitoring lower Yuba River fish communities. Specific duties include, but are not limited to, assisting biologists in conducting adult salmonid spawning and redd monitoring surveys, escapement surveys that include otolith extraction and other genetic sampling, temperature monitoring and maintenance of in-stream equipment, predation sampling using hook and line techniques, and Vaki Riverwatcher maintenance.
Eligible candidates will have a working knowledge of the scientific process and an understanding of the importance of following set protocols and procedures. Field work is required most days and will encompass a combination of hiking, kayaking, hook and line angling, underwater camera deployment, snorkeling, and motorized vessel travel to collect field data. Candidates must be able to hike or kayak up to 10 miles a day in remote areas, over rough terrain, and in adverse weather. They must be able to lift up to 50 lbs, perform strenuous field work, orient themselves using digital maps, operate 4wd vehicles and ATVs, and follow strict field and safety protocols. Since there are multiple agencies, technicians, biologists and hydrologists involved with the project and office space, candidates must have very good interpersonal skills and an overall positive attitude. Team-players are preferred.
This is a temporary position with a projected start date in September 2026 through March 2027. In general, crews work 4 days/week and 10 hours/day, but additional holiday and weekend work could be required.

- Collect and process fish carcasses for mark/recapture efforts using gaffs and machetes.
- Make standardized observations including but not limited to species identification, sex, length, and reproductive condition.
- Effectively identify and enumerate salmonid redds and features such as pot depression, tail spill, and gravel composition while using GPS devices.
- Accurately input biological and environmental data on field forms, and/or computer databases.
- Assist with daily QA/QC of collected and entered data.
- Maintain and clean field equipment, Vaki Riverwatchers, and boats.
- Adhere to and enforce all safety protocols including CDC guidelines for COVID-19.
- Assist with other project tasks as assigned.
