SALMON FISHING -- Anglers will be able to start fishing for a big run of chinook salmon in Idaho waters on April 22 under a fishing seasons and rules package adopted today by the Idaho Fish and Game Commission.

Chinook fishing will open in the Clearwater River, Snake River, Little Salmon and lower Salmon River in what's could be the third largest run since the fishery opened 12 years ago.
