MakoMike - in MA there is nothing unclear about culling
To prohibit the practice of high-grading, recreational fishermen may not retain legal-sized striped bass and release said fish in favor of another larger legal-sized striped bass captured subsequently. It shall be unlawful to keep striped bass alive in the water by attaching a line or chain to the fish or placing the fish in a live well or holding car.
I posted this recently, but years ago I met a rank novice fisherman at "my spot" who had gotten there ahead of me and had a legit #50 pound fish alive on a stringer, "in case I catch a better one". It still hurts to this day.
