If you fish for striped bass in Massachusetts, the core recreational rule is short: one fish per day, measuring at least 28 inches but less than 31 inches in total length, landed without a gaff and (when using natural bait) caught on an inline circle hook. Everything else in the Massachusetts striped bass regulations builds on those basics, including a $400-to-$10,000 fine range for violations and automatic permit suspensions on conviction.
The Permit You Need First
Anyone fishing recreationally in Massachusetts saltwater needs a Recreational Saltwater Fishing Permit issued by the Division of Marine Fisheries (DMF).1Mass.gov. Division of Marine Fisheries For 2026, the permit costs $10 for anglers under 60 and is free for anglers 60 and older.2Mass.gov. License Types and Fees It covers the calendar year and is available online through MassFishHunt.
A valid Massachusetts saltwater permit also satisfies the federal National Saltwater Angler Registry requirement, so no separate NOAA registration is needed.3NOAA Fisheries. Frequent Questions: National Saltwater Angler Registry The reverse is not true: the federal registry alone will not make you legal in state waters.
Slot Limit and Bag Limit
The recreational bag limit is one striped bass per day. That fish must measure at least 28 inches and less than 31 inches total length.4Mass.gov. Recreational Saltwater Fishing Regulations A fish of exactly 31 inches or larger goes back, and so does anything shorter than 28. The slot has been in place since 2023, and Addendum III to the interstate management plan left it unchanged for 2026.5Mass.gov. Striped Bass Management Update: Addendum III
There is no closed recreational season. The slot applies year-round.
How to Measure a Striped Bass
Total length is a straight-line measurement, not a measurement over the curve of the body. Measure from the tip of the closed jaw or snout to the farthest extremity of the tail with the upper and lower fork squeezed together.6Mass.gov. Measuring Striped Bass for Compliance with Size Limits Pinching the tail is the legally mandated technique, not a preference. A fanned tail reads longer than the fish actually is, and Environmental Police measure with the tail pinched.
This is also the coastwide standard under Addendum III to Amendment 7 of the interstate striped bass management plan.7Atlantic States Marine Fisheries Commission. ASMFC Atlantic Striped Bass Board Approves Addendum III Without Reductions in Fishery Removals
Handling Rules That Catch People Out
Three practices are explicitly illegal for recreational anglers:4Mass.gov. Recreational Saltwater Fishing Regulations
- High-grading. Once you retain a legal bass, you cannot release it later to swap in a bigger one. That first keeper is your fish for the day.
- Discarding a dead legal fish. If a bass within the slot dies after you catch it, it counts as your daily limit. Throwing it overboard is a violation.
- Live-holding. You cannot keep a bass alive on a stringer, in a live well, or in a holding car. The rule exists because live-holding is how high-grading happens.
Filleting rules are equally specific. The fish must stay whole (aside from gutting, bleeding, and scaling) until you are on shore with all fishing gear stowed. After that you may fillet the fish, but you can only possess two fillets per fish, and each fillet must have at least two square inches of skin intact for species identification.4Mass.gov. Recreational Saltwater Fishing Regulations Charter operators have a limited exception: they may fillet fish for customers during the trip if the racks are retained until all passengers leave the vessel.
Required Gear: Circle Hooks and No Gaffs
If you are fishing for striped bass with whole or cut natural bait, you must use inline (non-offset) circle hooks.8Mass.gov. Revised Circle Hook Requirement for Recreational Striped Bass Fishing An inline circle hook has its point turned perpendicularly back toward the shank with no lateral offset, forming a circular or oval shape. Sizes 7/0 to 10/0 generally suit fish within the recreational slot. One exception: if natural bait is attached to an artificial lure (a tube-and-worm rig, for example), the circle hook rule does not apply.4Mass.gov. Recreational Saltwater Fishing Regulations
Gaffing striped bass is prohibited for recreational anglers. Use a net, lip grip, or similar non-lethal device that does not pierce or puncture the fish.9Mass.gov. Commercial Striped Bass Management Proposal – Section: Gaffing Regulations The recreational gaff ban became an interstate mandate in 2023 under Amendment 7.
Commercial Fishing Is a Separate Framework
The recreational rules above do not apply to commercial harvest, and the commercial rules do not apply to recreational anglers. Commercial striped bass fishing requires a Commercial Fishing Permit with a striped bass endorsement, applied for or renewed by February 28 each year.10Mass.gov. Commercial Fishing Permits The minimum size is 35 inches with no upper limit, daily possession is capped at 15 fish for boat-based permit holders and 2 fish otherwise, and the fishery is hook-and-line only: netting, spearing, and snagging are all banned.11Mass.gov. Commercial Finfish Regulations Commercial fish must be tagged at the point of sale.12Mass.gov. Striped Bass Frequently Asked Questions (FAQ) – Section: What Are the Implications for a Commercial Harvester Tagging Requirement in Massachusetts?
If you hold only a recreational permit, none of the higher commercial size or possession numbers are available to you. Selling recreationally caught striped bass is not permitted.
Penalties for Violations
Under Massachusetts General Laws Chapter 130, Section 2, as amended effective November 2025, anyone who violates the state’s marine fisheries laws faces a fine of not less than $400 and up to $10,000 per violation, imprisonment for up to two and a half years, or both. The statute also authorizes a civil penalty of up to $10,000 for each violation as an alternative to criminal prosecution.13Mass.gov. Mass. General Laws c.130, Section 2
License suspension is a separate consequence layered on top of any fine. A first conviction results in a one-month suspension of all marine fishing permits. A second conviction triggers a three-month suspension. Any subsequent offense leads to a full-year suspension. During a suspension you cannot obtain a new permit of any kind, and any permit issued in error during that period is automatically void.14General Court of Massachusetts. Massachusetts General Laws Part I, Title XIX, Chapter 130, Section 2
Massachusetts Environmental Police and marine patrols enforce these rules through boat inspections, dock checks, and surveillance during peak fishing periods. Gear, boats, and catch used in connection with a violation can be seized. Enforcement is most visible in high-traffic areas like the Cape Cod Canal.
Federal exposure stacks on top. The Lacey Act makes it a federal crime to transport fish taken in violation of state law across state lines. A knowing violation involving fish worth more than $350 carries a federal fine of up to $20,000 and up to five years in prison, and lower-value violations can still draw civil penalties of up to $10,000 per offense.15Office of the Law Revision Counsel.

Rules Can Change Mid-Season
The DMF director has statutory authority under Chapter 130, Section 17A to adopt and change rules on size limits, seasons, bag limits, gear, and area closures, subject to Marine Fisheries Advisory Commission and Commissioner approval.16General Court of Massachusetts. Massachusetts General Laws Part I, Title XIX, Chapter 130, Section 17A Regulations can shift within a fishing season if conservation needs demand it. Checking the DMF recreational regulations page before each trip is the simplest way to avoid a violation caused by a rule that changed since your last outing.
