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.
