Unless weekly aggregate limits apply, all trip limits apply per calendar day or per trip, whichever is longer. For quota-managed species, the trip limit additionally applies to the person, the permit holder, or the vessel regardless of how many permits may be held. 

1) American eels are subject to regulation by the Division and the municipality. Please consult local regulations.

2) During the January 1 - March 31 period, DMF has reauthorized a pilot program that allows vessels to possess non-conforming quantities of black sea bass that represent lawfully harvested trip limits from RI, CT or NY (if so permitted) when offloading in MA. This fishery is closed to all gear types except fish weirs and small mesh trawlers during April. Fish weirs are not subject to daily trip limits. However, the combined landings of all fish weirs are subject to a 24,000-pound annual sub-quota allocation. When quota is available, trawlers may retain and land up to 100 pound of black sea bass incidentally caught in the springtime small mesh trawl squid fishery (April 23 - June 9) and summertime large mesh mixed trawl fishery (June 10 - October 31). Aggregate landings of black sea bass by trawlers fishing in the springtime small mesh trawl squid fishery are capped at 50,000 pounds; if that cap is reached then the retention and landing of black sea bass is prohibited. There are no closed fishing days during the springtime small mesh squid trawl fishery, whereas during the summertime large trawl fishery, the retention and landing of black sea bass may occur Sundays - Thursdays, consistent with the open fishing days for summer flounder. The directed trap and hook and line summertime fishery opens on the first open fishing day on or after July 8th and remains open until the annual quota has been landed. Open fishing days during the directed fishery are Sundays, Tuesdays, and Thursdays. For 2021, in-season adjustments were made affecting open fishing days in the directed trap and hook and line fishery. For these gears, from August 30 - September 30, open fishing days are Sunday - Thursday, and then on October 1 closed fishing days are eliminated and the fishery is open 7-days per week. 

3) Groundfish species are regulated under the federal Northeast Multispecies Management Plan and federal rules apply beyond state waters. Federal permit holders may land groundfish in accordance with federal rules. The trip limits listed apply to State Waters Groundfish Endorsement holders. Additionally, these limits apply to federally-permitted vessels while fishing in state waters unless the federal limit is more restrictive. Commercial fishermen who do not hold a State Waters Groundfish Endorsement or federal limited entry permit may take up to 25 pounds of regulated groundfish per day while fishing in state waters. Fishing for groundfish or with gears capable of catching groundfish in state waters is subject to various spatial/temporal closures, gear closures, and spawning closures. Please review 322 CMR 4.04, 4.06, 6.03 8.00 and 12.00 for more details. 

4) It is illegal to harvest cod from portions of Massachusetts Bay during the period of Nov. 15 to Jan. 31 (Winter Cod Conservation Zone) and April 16 to July 21 (Spring Cod Conservation Zone). See 322 CMR 8.07 for more details.

5) The P1 fishery (Jan 1 - Apr 22) is allocated 30% of the annual quota. By regulation, the trip limit for P1 starts at 1,000 pounds and is reduced to 100 lbs once 25% of the quota is landed. The P1 trip limit may also be increased by an in-season adjustment to allow commercial fishermen to have greater access to the available quota allocation. For 2021, the P1 trip limit was increased to 2,000 on January 1. DMF has also reauthorized a pilot program that allows vessels to possess non-conforming quantities of summer flounder that represent lawfully harvested trip limits from RI, CT or NY (if so permitted) when offloading in MA. The P2 (April 23 - Quota) fishery is allocated any quota that remains after P1 and is sub-divided into three seasons. During April 23 - June 9 season, longline fishermen and net fishermen may retain and land up to 100 pounds of summer flounder per trip and there are no closed fishing days; the retention and landing of fluke by other gear types is prohibited. During the directed summertime fishery (June 10 - September 30) open fishing days occur Sundays through Thursdays; it is unlawful to retain and land fluke on Fridays and Saturdays. Year-round, it is unlawful to land fluke during the period of 8 p.m.-6 a.m. 

6) A special permit for biomedical harvest is required to participate in the biomedical fishery. A bait fishery permit endorsement holder may not also hold a biomedical harvest special permit. All crabs harvested for biomedical purposes may only be sold to dealers authorized to purchase crabs harvested for biomedical purposes. After crabs are bled by the biomedical firm, harvesters must return the crabs to the area of harvest. All horseshoe crab harvest is subject to 5-day closures around new and full moons from late April through June. Mobile gear participants are subject to closed days on Fridays and Saturdays beginning on June 10. Trawlers who do not hold a bait fishery permit are authorized to retain, possess and land up to 75 crabs as incidental catch. 

7) Longfin squid are federally regulated under the Atlantic Mackerel, Squid, and Butterfish Management Plan. The annual commercial quota is allocated to three trimester periods - Trimester 1 (Jan 1 - April 30); Trimester 2 (May 1 - Aug 31) ; and Trimester 3 (Sept 1 - Dec 31). Federal limits are set by NOAA Fisheries based on permit type and may be adjusted in season in response to quota consumption; if you hold a federal permit for longfin squid, contact NOAA Fisheries for more details. From April 23 - June 9, the use of small mesh trawls for squid is authorized in those MA state-waters within the small mesh squid trawl exempted area (322 CMR 4.06) for those permit holders with a CAP-Squid regulated fishery endorsement. This season may be extended beyond June 9. DMF does not manage this seasonal small mesh fishery with a trip limit. However, federal trip limits apply to federal permit holders if they are fishing in state-waters and DMF may establish a trip limit in response to any actions taken by NOAA Fisheries. 

8) All commercial fisherman may retain and land up to 6,000 lbs of menhaden per day. If fishing under this 6,000 pound trip limit, fish are to be immediately stowed in 55-gallon barrels or standard fish totes. A level filled barrel is the equivalent of 350 pounds and a level filled fish tote is the equivalent of 117 pounds. Fish may be stored in both totes and barrels during the same trip, with one barrel having the equivalent weight as three totes. During the open entry fishery and the Episodic Event Fishery, fishermen fishing under the 6,000 pound limit are subject to a maximum purse seine size of 450' length by 48' depth. Note this 6,000 lb limit remains in effect after 100% of the quota is taken, as a small scale fishery and incident catch limit. Fishermen fishing under this limit are subject to the same fish storage and volume-to-weight requirements described above. However, they are also required to use a smaller purse seine net, which measures 300' long by 48' deep. Commercial fishermen with a limited entry menhaden commercial permit endorsement may take menhaden in excess of 6,000 lbs. The limited entry fishery is quota dependent and the trip limits are adjusted based on quota availability. The fishery opens with a 125,000 lb trip limit, which remains in effect until 85% of the quota is taken. A 25,000 lb trip limit goes into effect once 85% of the quota is taken and that trip limit remains in effect until 100% of the quota is taken. The use of nets within inshore waters is prohibited without an inshore net permit. The use of small bait nets of no more than 250 ft is authorized exempt from this prohibition. Consult 322 CMR 4.02 and 6.43 for more details.   

9) Monkfish may be processed at sea into tails and livers and landed as such products. Monkfish tails must be 11 inches in length, and the total weight of monkfish tails may not exceed 536 pounds. The weight of monkfish livers must not exceed 25% the weight of monkfish tails being landed or 10% the weight of the whole monkfish being landed.

10) Fish weirs are not subject to daily trip limits or closed fishing days. However, the combined landings of all fish weirs are subject to a 300,000-pound annual quota allocation. Trawlers may land scup 7 days per week. Trawlers fishing with mesh less than 5" are subject to a 1,000 lb possession limit from October 1 - April 14, a 2,000 lb possession limit from April 15 - June 15 and a 200 pound possession limit from June 16 - September 30. Hook and line and trap fishermen may land scup Sunday-Thursday during May; Sunday, Tuesday, and Wednesday in June; and then 7 days per week beginning July 1. The Winter I and Winter II periods are managed by the federal government, and seasons and limits are set by NMFS and complemented by DMF. The 2021 Winter I limit is 50,000 pounds and there are no closed fishing or landing days.  

11) Striped bass may be taken by hook and line gear only. Netting, spearing, and snagging striped bass is prohibited (G.L. c. 130 §100B). High-grading and fillet striped bass is prohibited. Fishermen fishing under the authority of a commercial boat permit or lobster permit when fishing aboard the vessel named on the permit are subject to the 15-fish limit. However, fishermen fishing under the authority of a commercial boat permit or lobster permit when fishing from another location (e.g., shore or another vessel) are subject to the 2-fish limit. All Individual and Rod and Reel permit holders are subject to the 2-fish limit as well. The commercial striped bass open fishing days for the 2021 season are Mondays, Tuesdays, and Wednesdays from June 16 - September 30 and Monday - Friday from October 1 - November 15. As the open fishing days are now consecutive, commercial fishermen will be afforded the opportunity to fish overnight tides spanning open fishing days. Accordingly, fishermen may retain, land, and sell fish on Monday and then begin fishing again on Monday and continue fishing into Tuesday morning to land and sell fish again Tuesday. However, if doing so, they may not possess or sell more than one limit during any single calendar day. If an open fishing day falls on the 3rd or 4th of July or the quota remains open on Labor Day, the commercial striped bass fishery will be closed. Possession limits apply to both permit holders, regardless of the number of permits held, and vessels, regardless of the number of permits on board. If the annual quota is not taken by November 15, then the fishery closes on November 16. 

12) Commercial fishermen must tag their commercial catch of tautog through the operculum with a metal Tautog ID tag upon the completion of commercial fishing activity that day and prior to sale or carring. It is unlawful to sell any tautog or for any dealer to receive a tautog that does not bear a Tautog ID tag in its operculum. Tautog ID tags will be provided to tautog permit holders by DMF in advance of the September 1 start of the season. However, fishermen must obtain the tag applicator independently. Commercial fishermen will be required to return all unused tags and submit a tagging report to DMF following the close of the fishery.
