Let me clarify what I meant when I referred to catfish being classified as a sport fish. Sport fish = desireable fish, everything else is bait or a rough fish. Sport fish can have many regulations on them. In states where catfish are not considered a sport fish, there are few regulations regarding methods or limits. In Missouri, catfish are one of our most prized sport fish. As such, we manage them to distrubute the harvest to as many anglers as possible and to protect the populations from over harvest. That's all I meant by "sport fish"
