Pacific States Marine Fisheries Commission is recruiting candidates to fill the role of a Fishery Biologist 1 - Tagging Trailer Operator based in Red Bluff, California. This is a seasonal, benefits-eligible position with an anticipated start date of December 14th, 2026. 

The Trailer Operator is responsible for operating and maintaining an automated fish-marking trailer that removes adipose fins and injects coded-wire tags (CWTs) into the snouts of juvenile salmon and steelhead. This is a highly technical position that requires strong troubleshooting skills, mechanical aptitude, attention to detail, and the ability to manage multiple systems simultaneously. Trailer Operators spend much of their time monitoring equipment performance, diagnosing problems, making adjustments, and maintaining the various components within the AutoFish trailer. These are complex systems with many processes occurring at once, making the position both challenging and rewarding. The Trailer Operator serves as the lead for an assigned shift and typically supervises one or two technicians, ensuring that fish are processed efficiently and accurately while maintaining equipment performance and quality-control standards. Additional information, photos, and videos of AutoFish systems can be found on the Northwest Marine Technology website.

This position offers valuable hands-on experience with both threatened and endangered salmonids while working at nine anadromous fish hatcheries throughout Northern California and collaborating with personnel from multiple agencies.
