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 100,000-200,000 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 its making a comeback. - Since 1963 the Lahontan Cutthroat trout has been
re-introduced into more than 50 streams.
