From what has been explained to me is, You can catch and release till you box your limit. I know, the bass fisherman do the catch/release all the time and it is a common practice with full limits in the box. But this year it seems you can be fined if caught still fishing after you have your limit in the livewell/box. I don't like it, but it is what is it. I was a bass guys for 20 yrs till switching to walleye. I'd bet they will be watching the perchers also this year. Limit and quit or you could be fined. So just don't keep that last one till your ready to quit.
