more than once, reach down grab the hook, pulled it out, still hooked up
shine the light down it's throat, grab the next hook, off they go!
I've also taken my hook out, and seen a piece of mono going down further... figured it was still hungry enough to bite my bait, must be OK, and swam off pretty lively when I set him free again/.
Also cleaned fish, and found remnants of rusted out hooks.
If your fishing bait, buy the ones that are not Stainless, or galvy, they will rot out in a couple of days inside the fish.
