Coincidence that this question came up this weekend. I hooked a hammer handle pike Saturday afternoon that ended up with the front treble from a rattletrap locking his jaw shut.
One hook in the bottom of his mouth, one through the top, and the third hooked into the bottom jaw from the outside. If that wasn’t bad enough, the hook shank was caught around the bone of his upper jaw and had worked it’s way about half way up toward his snout from the back end of the bone (by the gills, hard to explain unless you saw it I guess). His jaw was locked so tight by the hook that I couldn’t even get a hemostat in to grab the hook.
I ended up cutting the hooks in as many places as I could get to and turning him loose. Hopefully he can figure it out, poor fella.
