It's still against regulations to cull a fish. Don't get caught.
4)Striped bass must be kept whole, with head, tail and body intact - no mutilation permitted (other than evisceration). The discard of dead, legal size striped bass is prohibited. 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. Striped bass are measured from the tip of the snout or jaw (mouth closed) to the farthest extremity of the tail. Note: Permitted party/charter vessel operators may fillet striped bass for their customers. See 322 CMR 6.07 (4)(g) for details.
