I personely dont measure every fish and as pictures go i dont take a picture unless it can be done in a resonable amount of time. That protective slim does come back. I have had a place on Mille Lacs for years so i am not new to this. Also i fished tournaments for years and can say most of the tournaments are kill tounaments. In a tournament setting you are penalized for fish that won’t recover which encourages you to take care of your fish much more than launching it out of the boat
