A non-profit created by the Confederated Salish and Kootenai Tribes of the Flathead Indian Reservation in western Montana, Native Fish Keepers works hard to protect native trout in Flathead Lake. Their fisheries integrate traditional knowledge and current science. One of the largest threats to native bull trout and West Slope cutthroat trout is predation by non-native lake trout. Native Fish Keepers harvests and sells these non-native (but extremely delicious) lake trout to keep populations down so native fish can thrive. In the process they also create employment, support recreational angling, and supply fish to food banks.
