Hey All, so I've been fishing with a buddy who I'm finding to be a pretty lazy fisherman. I've had to help him with gut hooked fish in about 4 out of the last 5 fish he's caught. Last night, we were fishing for channel catfish in the Tempe Canals, and he landed a catfish... Gut hooked again, small, maybe 1-2 lbs. When I went to inspect the mouth, it looked like it's intestines were coming out of its mouth (not sure about this...this "mass" was firm, but had the appearance of worms/intestines/guts with brown goo oozing out), and the hook was swallowed behind whatever the mass was, I couldn't even see it. We were fishing in about 10-15 feet of water, so I don't think the swim bladder would have been effected (unless it was lacerated by a swallowed hook). Anyway, the fish seemed like it was struggling, worse than normal when caught... So instead of just clipping the line close to the mouth and releasing, I decided to mercy kill it and donate it to the canal for other fish to eat. I've felt pretty bad ever since; I hate to cause anything undo pain (fishing in general does this, but that, I've accepted). But in the moment I didn't want the fish to suffer anymore, but in hindsight, maybe it was some normal finding in its mouth and it would have lived a good life. I'm stressing. I also have now preached to my friend to keep a tight line, react faster, and am going to tell him to switch to circle hooks to stop his gut hooking.
