Hmmmm, Lot's of different views on this one. Here's my take: Don't intentionally snag fish. Don't keep a foul hooked fish, I don't care if it's hatchery or Native.... Don't keep it. If they fish is Head Shot, then it's fair game....Simple as that. If the fish is hooked in the top of the head, or back by the gills, I consider it to be foul hooked and I let it go. If the line ran through the fish's mouth, I don't care if the hook is down in its throat or outside its lip, it's going home with me. I'll bonk it everytime.
