Fish Are Our Friends, Not Food The Lahontan Cutthroat Trout and the Piute Sculpin are fish that have always lived in Sagehen Creek. The Lahontan Cutthroat Trout became an endangered fish because of over fishing and because of more aggressive fish taking over the streams. Due to the Sculpins small size, they were never considered as game fish and therefore never over fished and never listed as endangered. The Lahontan Cutthroat Trout and Piute Sculpin have similar needs even though they have experienced different histories. Thanks to re-introduction efforts, the Lahontan Cutthroat Trout and Piute Sculpin now find themselves living with one another again in Sagehen Creek. The Lahontan Cutthroat trout was the diet of Piutes and other Native tribes. Between 1873 and 1922 commercial fisheries took out 100, ,000 pounds of Lahontan Cutthroat Trout each year from Pyramid, Walker and Tahoe Lakes. In 1900, over 9600 pounds of the fish were taken out from the Truckee River alone. This native fish has disappeared from Lake Tahoe, but it’s making a comeback. Since 1963 the Lahontan Cutthroat trout has been re-introduced into more than 50 streams. ARC 2004 Summer Program Aldo Xochihua, Gabriela Villalobos, Francisco Delgado
