RENO, Nev. (AP) — Scientists are hailing the return of a threatened fish to its native spawning grounds in Nevada for the first time in 76 years, calling it a milestone in efforts to produce a self-sustaining population of the species at a desert lake near Reno.
Biologists say some 90 Lahontan cutthroat trout weighing up to 25 pounds spawned this spring along the extreme lower 2-mile section of the Truckee River, which flows into Pyramid Lake.
The lake's cutthroats last spawned in the river in 1938 and vanished from Pyramid by the 1940s due to over-fishing, degraded habitat and the introduction of non-native fish.
Lisa Heki of the U.S. Fish and Wildlife Service says the spawning offers hope that the species reintroduced into the lake in 2006 will be able to reproduce on its own in the future without the help of hatcheries.
The Reno Gazette-Journal broke the story about the spawning.
