I got this 19" blue catfish about a week ago. Thought it might interest frolks for a couple of reasons. #1, the fish had a large treble hook deep in his mouth already when he took my cutbait and circle hook. #2; this extra hook didn't seem to be hurting him at all, he was still eating and looked good. The hook was a bit rusty, but in no way was it being disolved yet. #3; I took pictures. You can see the treble in his mouth just to the right of my circle hook in the corner of his lip in the first picture. That's right where the circle hooks always get them for me, right in the corner. I took both hooks out and he swam away. So, apparently, in some instances, leaving a hook in a badly hooked catfish doesn't hurt them too badly, at least in the short run. I've caught other catfish here and there with a hook already in their mouth and they too, didn't seem too bad for the wear. I felt lucky to get a quick picture this time. There is a better photo of the fish in my photo album at the link below.
