Idaho has cod?
Burbot is the only freshwater ling cod species in North America found on the Kootenai River.
Idaho Fish and Game launched an extensive restoration program to reestablish this native species on the Kootenai River. The burbot population was close to being a threatened species, and as of 2019 the population has increased and the fishery has reopened since 2019.
Protecting bull trout.
Bull trout are a threatened species protected by federal law. No harvest is allowed.
Bull trout are native fish to Idaho and can be identified by their yellow spots on the upper body, and red or orange spots on the sides with no blueish halos around spots. Bull trout were listed as a threatened species in 1998 and Idaho Fish and Game has worked hard at protecting this species since 1994.
