KALISPELL, Mont. -

State wildlife officials are looking for information about who introduced northern pike into Lake Mary Ronan, which is being managed as a salmon and trout fishery.
    
Fish, Wildlife and Parks information officer John Fraley says a Missoula angler caught two northern pike at the lake west of Flathead Lake on June 26.
    
FWP Warden Ron Howell said these are the first northern pike reported in the lake, so he assumes they were illegally introduced.
    
Northern pike are predatory and could impact the kokanee salmon and trout fishery. Kokanee in Lake Mary Ronan serve as the egg source for stocking lakes across the state.
    
Anyone with information is asked to call 1-800-TIP-MONT (847-6668) and anyone who catches a northern pike at Lake Mary Ronan is asked to call FWP at 406-752-5501.
