At our lake, the most people we having fishing at one time (that we know of) is about 5 people who would all be our friends.
We debarb all of the hooks for live bait fishing and lures.
We also keep these "plunger" type things around. I don't know what they're called, but they are basically a 7-8" red plastic shaft with two oval shaped balls on either end. On ball is smaller for smaller fish, and the other ball is bigger for bigger fish. We have about 95% plus in de-hooking fish when they are gullet hooked. Like Dave says, if it's too far in, we cut the line and leave the hook.
For Norm, I don't know if you are at your lake when people fish your lake.
