May 29, 2025 — Biologists from the Northwest Fisheries Science Center again participated in the celebration of Pacific salmon held every spring for elementary students from Benton County, Washington. The “Salmon Summit” on April 29–30, 2025, culminated months of learning about salmon life cycles in the classroom.
Fourth graders from several elementary schools first raise juvenile Chinook salmon from egg to par. They learn about the salmon life cycle as part of the Salmon in the Classroom program managed by the Benton Conservation District. The students also work with NOAA Fisheries scientists, who help dissect an adult male and female salmon in class.
“We’ve been visiting classrooms every year since 2011,” said Jesse Lamb, fisheries biologist with Pasco Research Station. “And every year, we love educating students about the thousands, and sometimes hundreds of thousands, of salmon swimming up the Columbia River within just a few miles of their homes.”
This year, Lamb joined fisheries scientist Loren Stearman to visit eight elementary schools to conduct salmon dissections and teach more than 600 students about salmon anatomy.
That prepares them for the 2-day Salmon Summit event in Kennewick, Washington. More than 3,200 students learned about salmon science at 72 hands-on, interactive stations staffed by state and federal agencies, tribes, and nonprofit organizations. At the NOAA Fisheries tagging station, students saw how we use passive integrated transponder (PIT) tag technology to conduct research on salmon and steelhead throughout the Pacific Northwest. With electrofishing and seining gear on display, scientists described how the gear is used to capture juvenile salmon parr in remote streams before they migrate downstream.
“Tagging fish in real time is an eye-opening experience for some of these students. It’s also a chance for us to demonstrate an approach that we’ve been using for more than 3 decades to monitor the movement, growth, and survival of threatened wild Chinook salmon in the Snake River and its tributaries,” said Stearman.
Snake River Chinook salmon are listed as threatened under the Endangered Species Act. NOAA Fisheries biologists use juvenile Chinook salmon from hatcheries that the students have been rearing in their classrooms to demonstrate our research protocol. First they anesthetize the fish, then tag and measure them. Students get to inspect a PIT tag as biologists explain how it provides information about the fish’s movement. The biologists demonstrate how the tag code and fish length and weight data are stored digitally for each unique individual.
Finally, the students release a tagged fish through a special tank and hose that sends it directly into the Columbia River to start its journey.
“The students always have questions about the likelihood of their fish surviving to the ocean and eventually returning to spawn. That’s our chance to pique their interest about the many threats facing salmon throughout their life cycle, and perhaps inspire the next generation to pursue a career in saving salmon,” said Lamb.
