if your catching them in places like the willamette or any river for the matter, specifically rivers with salmon/steelhead or even trout runs you should do Oregon the justice of killing them whether you plan to eat them or not.
They are a non native invasive species and are much more vicious a predator than squawfish that we have all tagged as so terrible (even though squaws are native). They are not supposed to be here, so I go out of my way to make sure every one I land dies. and becomes fertilizer on the bank so that atleast they will benefit oregon in one way.
Neither smallmouth or largemouth belong on a table unless you are in a survival situation in my honest opinion.
