While it is now common knowledge that Pacific salmon die after spawning, in 1881 American fish culturalists fiercely debated the matter. In a magazine article, US Fish Commission official Livingston Stone surveyed Winnemem Wintu workers at his hatchery on the McCloud River in Northern California. Acknowledging their unique expertise from “having spent their entire lives on the river since time immemorial,” Stone noted, “they were unanimous in saying that all the salmon died. There was not one dissenting opinion.” After establishing the salmon hatchery on the McCloud in 1871, Stone would succeed in exporting millions of artificially inseminated salmon eggs around the world. While Stone is still memorialized as a forefather of modern fisheries science, scholars have elided the Winnemem Wintu ecological knowledge he relied upon from their histories. The few that do reference the Winnemem Wintu workers characterize them as helpful but naive servants and laud their partnership with Stone as an exemplar of multicultural cooperation. However, this paper recasts the narrative by foregrounding the oral history of the Winnemem Wintu, who contend Stone learned from them about salmon biology but ignored their most important lessons: that salmon are sentient bearers of ecological wisdom who must be followed rather than controlled and that hatcheries cannot replace the protection of riverine habitat. Their oral history and newly excavated archival documents also reveal how the hatchery facilitated the extra-legal seizure of Indigenous lands and suppression of Winnemem Wintu ceremonies. Written and researched in close collaboration with Winnemem Wintu leadership, this paper connects Stone’s scientific legacy to colonial impulses that continue to influence modern fisheries biology. The tribe argues that rewriting the history of Stone’s operation is an essential intervention to unravel the hatchery-centric culture of wildlife agencies that hampers the tribe’s restoration of wild salmon in their ancestral watershed.
