The Columbia River’s annual rotation of anadromous fish included steelhead trout, sturgeon, coho, chinook and sockeye salmon, chum or dog salmon and the otherworldly Pacific lamprey — a glossy-gray, eel-like fish with seven round gills bored into its sides like the tone holes of a cedar flute.
The Indigenous people of the Columbia Basin have an agreement with salmon. It’s the most honored animal, the first to sacrifice itself in a contract of reciprocal care: The people would care for the salmon and its waters, and the salmon would feed the people. There’s a similar agreement with the oldest inhabitant of the watershed — and one of the oldest creatures in the world — the Pacific lamprey. Or, as most Northwest Natives call them, eels.
Lamprey have lived on Earth for 450 million years. To them, dinosaurs were a passing fad, and the North American continent is a fairly recent development. Lamprey swim out to sea as juveniles, looking for hosts like salmon to parasitize until they are mature enough to swim up some other river to spawn. Adult lamprey are calorie-dense and slow, protecting their hosts and cousins, the salmon, by acting as a predation buffer in another gesture of reciprocal care.
Though lamprey play a key role in Pacific watershed ecosystems, they remain understudied outside of tribal fisheries. They’re the target of misplaced disdain, in part because they’re easily confused with sea lamprey, an Atlantic species that caused ecological havoc in the Great Lakes after a 19th century shipping canal allowed them to invade. Pacific lamprey are a different species, in a different ecosystem; they belong here, just like the people they sustain.
