Going back probably 15 plus years now, the Wardens stopped a couple guys leaving the north Maine woods with a few hundred small brook trout in their possession. I think they’d only been there two days, three at the most. They’d been fishing some of the smaller brooks and rivers in the area. You know the hurting a couple guys with a can of worms can do to to a small stream full of wild brookies? Takes quite a while to recover from that. Do it long enough to the wrong stream and it may not recover at all.
If they caught a couple hundred in two days, chances are those brookies weren't about to go extinct.
