COEUR D'ALENE, Idaho (AP) — A tribe is implementing a temporary bounty on northern pike as it studies cutthroat trout predators.

The Coeur d'Alene Press reports starting Oct. 1, the tribe will pay anglers for the first 1,000 northern pike caught on the southern portion of Lake Coeur d'Alene and turned in at a Heyburn State Park Headquarters check station. Tribe spokeswoman Heather Keen said the Catch for Cash program was created to enlist anglers in gathering more data on the impact of a growing northern pike population in the southern portion of the lake. The program could be extended after May.

North Idaho Pike Association chairman Brock Morrow says the tribe overstepped its authority by including water where Idaho claims jurisdiction. The tribe is discussing the program with state wildlife officials next week.
