Salmon Summit

Researchers move STEM education outside

Janak and other fish researchers released 500 fish into the Columbia River as part of Salmon Summit, an educational program offering elementary schools an opportunity to learn about the life cycle of salmon.

Every year, fourth and fifth graders from across Eastern Washington raise fish as part of the Salmon in the Classroom curriculum. Salmon in the Classroom is sponsored by the Benton Conservation District, an organization that  stewards conservation practices involving soil, water, air, fish, and wildlife in Benton County, Washington. The Salmon in the Classroom unit allows students to hatch salmon eggs at school, study salmon life cycle and habitat, and learn to test water quality. The curriculum culminates with the release of the salmon into the Columbia River in an event known as Salmon Summit.

This year's Salmon Summit reached thousands of students across the region both in person and through the virtual livestream on April 15 and 16. Pacific Northwest National Laboratory (PNNL) staff demonstrated the tagging and release of 500 juvenile salmon, raised at PNNL's Aquatic Research Laboratory, into the Columbia River.

Each fish was implanted with a passive tag, known as a PIT tag, that has a unique code that allows researchers to identify fish throughout their life. Certain passage routes at downstream dams have detection equipment to identify fish as they swim by. PNNL is monitoring these detections using a centralized database called PTAGIS and will continue to report on progress. Fish can only be detected if they pass through the juvenile bypass systems at the dams. Typically, 5 to 10 percent of fish use these routes, so the other fish that aren't detected likely take another route on their way to the ocean.

Each fish was implanted with a passive tag to allow scientists to track their movements and receive information about when a fish passes through a hydropower dam or reaches the ocean.

The Benton Conservation District organized the broader Salmon Summit in-person event and supported recruitment of classrooms for the livestream event, and the Department of Energy's Water Power Technologies Office sponsored PNNL’s PIT tagging station and the live stream event. The City of Kennewick supported this event by allowing access at Columbia Park. Researchers fielded questions about salmon biology and the tagging process, education and careers in biology, Earth sciences, engineering, and science communications. The most popular questions were about predators and what happens when salmon that are tagged are eaten.
