The Lahontan Cutthroat trout, (Oncorhynchus clarki henshawi) is the largest subspecies of cutthroat trout, and the state fish of Nevada. The largest lacustrine population is found in Pyramid Lake, Nevada. It spawns during early spring in the lower Truckee River within the Pyramid Lake Indian Reservation. It was federally listed as endangered, then reclassified as 'threatened' in 1975. Three tribal fish hatcheries help maintain a stable population of this fish species. A Paiute man caught the world record in Pyramid Lake around 1925. A fisherman caught and released a fish weighing almost 25 pounds in 2007.
