Blue catfish

This question is difficult to answer because blue catfish have never been officially stocked in Idaho.  With that said, we do know that a few blue catfish have been inadvertently released in Idaho waters from a couple of different sources.  Most channel catfish stocked in Idaho waters from the Southeastern U.S.. We send stocking trucks from Idaho on the long road trip to pickup the fish for distribution to various waters around the state.  Several years ago, we noticed a few blue catfish mixed with the channel catfish at were stocked.  We no longer purchase channel catfish from this fish supplier. Recently, we also discovered that some of the commercial producers of catfish in Idaho also had blue catfish mixed with their channel catfish.  Occasionally, fish do escape from these facilities and make their way into public waters.  We've documented several blue catfish in the Snake River below facilities raising channel catfish in recent years. Your chances of catching a blue catfish in Idaho are slim.  If you do, consider yourself as one of the lucky few.
