A fishing advocacy group is offering a $10,000 reward for information on individuals suspected of illegally stocking non-native fish in several Montana lakes. 

Montana Trout Unlimited offered the reward for information leading to the apprehension and conviction of those responsible for planting northern pike in Lake Mary Ronan, smallmouth bass in Seeley Lake and walleye in Noxon Reservoir.
The group says introduced fish can harm native species by preying on them, spreading disease and harming water quality.

"We want the public's help," said Trout Unlimited's Kelly Willett. "We're asking other Montanans to join us. If you're out enjoying the wilderness and see something suspicious, to call it in because you have the power to save a river or stream or lake. The stakes are high."
To report information on illegal stocking of fish, contact Montana Fish Wildlife and Parks at 1-800-TIP-MONT.
