Oklahoma has it legalized , there are a lot of catfish there, Iowa doesn't have near the population of catfish so why hurt it any more it has been proven it hurts the population that's why states have reduced the take quota and not made it legal, you want a rush smoke crack, and if some one thinks they know what's in a hole before they stick their hand in it they should patent their ability, we used to box trap catfish on the Missouri river when the stock yards was around and just loaded up on the channel cats now there isn't near the channel cats, leave the short fingers and dumb idea's to the rednecks.
