Here are the MASSACHUSETTS regulations on striped bass:
Minimum Length: 28 inches (tip of closed mouth to tip of tail)
Catch Limit: 2 Fish (per person)
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.
FYI: evisceration - to remove the entrails from; disembowel
These seem to conflict
322 CMR 6.07 (7) (e)
(7) Prohibitions. It shall be unlawful for:
(e) a recreational fisherman to mutilate any striped bass in such a way as to interfere with or affect a proper and adequate measurement of the fish
; such mutilation shall be prima facie evidence of a violation of this section
Note: Permitted party/charter vessel operators may fillet striped bass for their customers.
See 322 CMR 6.07 (4)(g)
(g) For-hire vessels permitted under the authority of 322 CMR 7.01(4) may fillet or process legal sized striped bass for their recreational customers at sea provided that: 1. not more than four fillets taken from legal striped bass, minimum of 28" total length, are in possession for each customer of that trip representing the equivalent of two fish per customer; the skin must be left on the fillet; and 2. the total number of striped bass onboard the fishing vessel does not exceed twice the number of persons.
