About the Species
The commercial monkfish fishery in the U.S. operates from Maine to North Carolina out to the continental margin. Trawl gear is primarily used in northern waters, and gillnet gear in southern waters. Because it is common for monkfish to be caught in conjunction with groundfish, you will see a lot of the information on this site also relates to the northeast multispecies (groundfish) fishery. The monkfish fishery is managed using a days-at-sea and trip limit management system. There is no known directed recreational fishery for monkfish. The market for monkfish is for human consumption. U.S. wild-caught monkfish is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations. Implementing regulations are found at 50 CFR part 648 subpart F.
Population
Above target population levels.
Fishing Rate
At recommended levels.
Habitat Impacts
Area closures and gear restrictions protect habitat affected by some kinds of trawl gear.
Bycatch
Regulations limit possession of bycatch species and require modified fishing gear to reduce bycatch.
Population Status
- There are two stocks of monkfish: Gulf of Maine / Northern Georges Bank and Southern Georges Bank / Mid-Atlantic. According to the most recent stock assessments:
- The Gulf of Maine / Northern Georges Bank stock is not overfished and not subject to overfishing (2013 stock assessment). Summary stock assessment information can be found on Stock SMART.
- The Southern Georges Bank / Mid-Atlantic stock is not overfished and not subject to overfishing (2013 stock assessment). Summary stock assessment information can be found on Stock SMART.
Appearance
- Monkfish have mottled dark brown to olive-green skin on top and whitish skin underneath.
- They are described as tadpole-like in appearance, with a body that is mostly a broad head with a large mouth and a narrow, tapering body.
Biology
- Female monkfish grow larger and live longer than male monkfish. Females live to at least 13 years and grow to more than 4½ feet long, while males only live about 7 years and grow to almost 3 feet long.
- Males and females are able to reproduce when they reach about 14 inches and 16 inches long, respectively.
- Monkfish spawn from February to October.
- Females release large egg veils that can contain more than 1 million eggs.
- These egg veils float near the surface along with the prevailing currents for 1 to 3 weeks (depending on temperature) until the veil disintegrates and the larvae hatch.
- Monkfish migrate seasonally to spawn and feed.
- They travel by slowly swimming or by using the sturdy base of their pectoral fins to walk.
- Scientists speculate that their wing-like pectoral fins may be used to ride currents.
- Monkfish are opportunistic feeders, eating whatever prey is most available at the time.
- Larvae feed on zooplankton (tiny floating animals). Juveniles mostly eat small fish, shrimp, and squid.
- Adults mainly eat fish, including other monkfish, but also feed on crustaceans, mollusks, seabirds, and diving ducks.
- Monkfish ambush their prey—they use a modified spine on their head as a fishing pole and bait to lure small fish toward their mouths.
- When the prey comes near, the monkfish takes a large gulp, which sucks the prey into its mouth and traps it behind rows of back-pointing teeth.
- Large monkfish have few predators.
- Predacious fish such as swordfish, sharks, and thorny skate prey on small monkfish.
Where They Live
Range
- Monkfish are found in the Northwest Atlantic Ocean from the Grand Banks and northern Gulf of St. Lawrence south to Cape Hatteras, North Carolina.
- They can tolerate a wide range of temperatures and depths, from inshore waters down to nearly 3,000 feet.
- Monkfish migrate seasonally to spawn and feed.
Habitat
- Monkfish live on the ocean floor, typically on sand, mud, and shell habitats.
- Adults spend most of their time on the bottom, often in a depression or partially covered in sediment. They also spend some time off the bottom, probably riding currents to help with migration.
Fishery Management
- NOAA Fisheries and the New England and Mid-Atlantic Fishery Management Councils manage the monkfish fishery.
- The New England Fishery Management Council has the lead for developing measures in the monkfish fishery management plan.
- Managed under the Monkfish Fishery Management Plan:
- The monkfish fishery in U.S. waters is divided into two management areas north and south of Georges Bank to accommodate differences in monkfish fishing practices.
- Both areas are managed under the same plan.
- The Northern Fishery Management Area covers the Gulf of Maine and the northern part of Georges Bank. The Southern Fishery Management Area extends from the southern flank of Georges Bank through the Mid-Atlantic Bight to North Carolina.
- Management measures include annual catch limits, limited access permits, size limits, landing limits, and measures to reduce bycatch and impacts on habitat.
Harvest
- Commercial fishery:
- In 2021, commercial landings of monkfish totaled 15 million pounds and were valued at $10 million, according to the NOAA Fisheries commercial fishing landings database.
- Monkfish is one of the highest valued finfish in the Northeast.
- Almost all of the monkfish for sale in the United States comes from U.S. fisheries.
- Gear types, habitat impacts, and bycatch:
- Fishermen harvest monkfish using bottom trawls, sink gillnets, and scallop dredges.
- Most monkfish caught in the Northern Fishery Management Area are caught by vessels using bottom-trawl gear targeting groundfish.
- Most monkfish caught in the Southern Fishery Management area are caught by vessels using gillnets.
- Although bottom trawls can affect marine habitat, most bottom trawls catch monkfish over sand and mud habitats, which tend to recover from any disturbance more quickly than more structured habitats.
- Managers and researchers believe that monkfish essential fish habitat is only minimally vulnerable to the effects of bottom trawls and sink gillnet gear.
- Managers have implemented a variety of measures to protect habitat of other bottom-dwelling fish from any potential impacts from the monkfish fishery:
- Two areas are closed to monkfish fishing (all gears) year-round to protect sensitive habitat.
- Fishermen must use gear with specific requirements that prevent them from fishing in sensitive hard bottom areas.
- Monkfish fisheries sometimes incidentally catch spiny dogfish and skates, which fishermen are allowed to keep as long as they have the appropriate federal permits and comply with the appropriate regulations for these fisheries.
- There is a limit on the amount of bycatch of other fish species allowed in the monkfish fishery, including possession and landing limits and annual quotas specified in fisheries for those species.
- Mesh on gillnets and trawl nets must be larger than the established minimum size to reduce bycatch.
- Gillnets used to target monkfish can incidentally capture protected species, such as sea turtles, large whales (right, humpback, and fin whales), harbor porpoise, dolphins, and Atlantic sturgeon.
- Monkfish fishermen follow a number of measures to reduce the fishery’s potential impact on protected species:
- In the Mid-Atlantic, management measures prohibit gillnet vessels from using large mesh (7 inches or greater) gillnets in some areas during certain times of the year to protect migrating sea turtles.
- Closures are timed based on projected sea surface temperatures in fishing areas, as sea turtles are known to migrate into these areas when temperatures are about 52 degrees Fahrenheit or higher.
- The closures move large-mesh gillnetting north in advance of sea turtles migrating into fishing areas and, along with other precautions, have greatly reduced incidental catch of sea turtles in the monkfish fishery.

Seafood Overview
Is Monkfish Sustainable?
U.S. wild-caught monkfish is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.
Availability
Year-round, with peaks in the late fall and spring.
Source
U.S. wild-caught from Maine to North Carolina.
Taste
Mild.
Texture
The tail meat is firm, dense, and relatively boneless. The meat is not flaky and has a texture similar to lobster meat. Raw monkfish is covered with a blue-gray membrane, which should be removed before cooking. If left on, the membrane will shrink, and the meat will curl and become tough.
Health Benefits
Low in sodium; a good source of niacin, vitamins B6 and B12, and potassium; and a very good source of protein, phosphorus, and selenium.

Exempted Fishing
What is an Exempted Fishery?
Exempted fisheries allow vessels to fish for specific species without being subject to certain Northeast multispecies regulations, including days-at-sea, provided the bycatch of regulated species is minimal. To be approved and implemented, exemption programs must have demonstrated that incidental catch of Northeast multispecies is less than five percent of the total catch, by weight, and that the exemption will not jeopardize fishing mortality objectives.
Monkfish Fishery Exemptions
To fish a monkfish day-at-sea (DAS) as monkfish-only DAS (not also using scallop or Northeast multispecies DAS), you must fish exclusively in an exemption area or exempted fishery. If you choose to fish outside of the exemption area or an exempted fishery, you are also required to use a Northeast multispecies or scallop DAS simultaneously with your monkfish DAS.
Monkfish Exemption Areas
There are five main exemption areas that apply to the monkfish fishery. Visit the provided summary pages for more detailed information about each one.
- Gulf of Maine (GOM)/Georges Bank (GB) Monkfish Gillnet Exemption
- Southern New England (SNE) Monkfish Trawl Exemption Area
- SNE Monkfish Gillnet Exemption Area
- Mid-Atlantic (MA) Exemption Area
- MA Monkfish Exempted Gillnet Fishery
Possession Limits and Mesh Sizes Associated with the SNE and MA Exemption Areas
If you are using trawl gear, you need to be aware that your monkfish incidental trip limits depend upon whether you are fishing on either the east side or the west side of the boundary between the SNE and MA exemption areas. The chart below depicts this area and the table at the end of this section shows the different incidental trip limits.
Minimum mesh size is defined by the summer flounder regulations when fishing west of the SNE/MA Exemption Area boundary, but is defined by the Northeast multispecies regulations when fishing east of this boundary in the SNE Regulated Mesh Area and Exemption Areas. For a specific breakdown of areas, gear, and trip limits, refer to the table below.
Southern Exemption Area Trip Limits by Mesh Size
| Side of SNE/MA Exemption Area Boundary | West | East | ||
|---|---|---|---|---|
| Smallest Mesh Fished During Trip | 5.5-inch diamond/6-inch square, or larger, in body, extensions, and codend | Smaller than 5.5-inch diamond/6-inch square in body, extensions, and codend | Smaller than 6-inch diamond/ 6.5-inch square in body and extensions; and 6.5-inch square or diamond in the codend | 6-inch diamond/ 6.5 inch square, or larger, in body and extensions; and 6.5-inch square or diamond, or larger, in the codend |
| Landing Limit1 (per trip unless stated otherwise) | 5% of total weight of fish aboard, up to 450 lb per trip | 50 lb per day2, up to 150 lb per trip | 5% of total weight of fish aboard, not to exceed 50 lb per day2, up to 150 lb per trip | |
1Any prorated combination of tail weight and whole weight may also be landed based on the conversion factor for tail weight to whole weight of 2.91 (tail weight x 2.91 = whole weight; or whole weight/2.91 = tail weight). A vessel may also possess or land monkfish livers up to 25% of the tail weight of monkfish, or up to 10% of the whole weight of monkfish, per trip. If a vessel possesses or lands both monkfish tails and whole monkfish, the vessel may land livers up to 10% of the whole weight of monkfish per trip using the following weight ratio: (0.10) x [(tail weight x 2.91) + (whole fish x 1)]. Vessels may also land monkfish heads separate from tails, provided the total head weight does not exceed 1.91 times the total weight of tails onboard.
2A day is the 24-hour period that begins when the vessel leaves port or, if the vessel has an operational VMS, when the vessel crosses the VMS demarcation line when leaving port and ends when the vessel returns to port or, if the vessel has an operational VMS, crosses the VMS demarcation line on its return to port.
A vessel's monkfish incidental catch limit is based upon the mesh size of the smallest mesh fished during the trip. For example, if you are fishing for squid using a 1-7/8-inch diamond mesh and for summer flounder using a 5.5-inch diamond mesh on the same trip west of the 72Ë 30â W boundary line, you are subject to the more restrictive possession limit of 50 lb tail weight per day, up to 150 lb tail weight per trip.
Northwest Atlantic Fisheries Organization (NAFO) Regulatory Area Exemption Program
A vessel issued a valid High Seas Fishing Compliance Permit and that complies with the associated requirements is exempt from monkfish permit, mesh size, effort-control, and possession limit restrictions while transiting the EEZ with monkfish on board the vessel, or landing monkfish in U.S. ports that were caught while fishing in the NAFO Regulatory Area. A letter of authorization is required for participation in the NAFO Exemption Program, and other requirements and restrictions may apply. For more information, visit the NAFO website.
Management Overview
The monkfish fishery is jointly managed by the New England and Mid-Atlantic Fishery Management Councils. NOAA Fisheries is the implementing body for rules and regulations within the fishery. The fishery is managed under a days-at-sea (DAS are the number of days that can be fished per year) management system with corresponding trip limits per DAS.
The range for the monkfish fishery is the EEZ north of the North Carolina/South Carolina border (Maine through North Carolina). However, there are two separate management areas within that range based on different fishing activity/operations between the two areas: the Northern Fishery Management Area (NFMA) and the Southern Fishery Management Area (SFMA). The boundary between the NFMA and the SFMA runs south along the 70° W longitude line from the south-facing shoreline of Cape Cod, MA, to 41° N latitude, then eastward to the U.S.-Canada maritime boundary. There are also two closed areas affected monkfish vessels. For more information on these areas, visit our Monkfish Fishery Closed Areas page.
Different Requirements in the NMFA:
Because the regulations for the SFMA are more restrictive (lower possession limits) than the NFMA, a federally-permitted monkfish vessel fishing exclusively in the NFMA without an operational vessel monitoring system (VMS) on board must obtain a monkfish Letter of Authorization (LOA) from NOAA Fisheries. This LOA is issued for a minimum of 7 days and may be obtained by calling our Permit Office at (978) 282-8438. The non-VMS vessel must also make the proper trip declaration through the interactive voice response (IVR) call-in system. If a vessel has not obtained the LOA and makes a trip declaration through the IVR, it is presumed to have fished in the SFMA, and will be held to the more restrictive requirements of the SFMA.
This does not apply to vessels with an operational VMS unit. Such vessels must declare the area to be fished using VMS.
Requirement for NFMA Vessels Transiting Through the SFMA:
A vessel that has declared into the NFMA (LOA and IVR, or through VMS), may transit the SFMA, provided that it does not harvest or possess monkfish or any other fish from the SFMA. All fishing gear must also be properly stowed and not available for immediate use.
Management Plans
2022 Monkfish Specifications (May 1, 2022-April 30, 2023)
| Stock | Northern Monkfish | Southern Monkfish |
|---|---|---|
| Overfishing Limit (OFL) | 17,805 mt | 23,204 mt |
| Acceptable Biological Catch (ABC) | 8,351 mt | 12,316 mt |
| Annual Catch Limit (ACL) | 8,351 mt | 12,316 mt |
| Annual Catch Target (ACT) | 8,101 mt | 11,947 mt |
| Total Allowable Landings (TAL) | 6,624 mt | 5,882 mt |
Research Set-Aside: 500 Days at Sea (DAS) per year.
How often do the quotas change for this fishery? Quotas, catch limits, and other fishery management measures are reviewed annually and may be adjusted for each stock for multiple years as necessary.
What if specifications are not in place at the start of the fishing year? Existing specifications roll over.
Are there in-season adjustments (changes mid-fishing year) in this fishery? Adjustments to management measures may be made by the Councils or the Regional Administrator or the Joint Monkfish Oversight Committee with the approval of the Council at any time (including in-season), if it is determined that action is necessary to meet or be consistent with the goals and objectives of the Monkfish Fishery Management Plan. However, these situations would require public comment and at least one Council meeting to take action.
Accountability Measures: The ACTs established for each management area are the basis for setting management measures (DAS and trip limits) in those areas after accounting for incidental catch in non-directed fisheries and discards.
In the event that an ACL is exceeded in a given fishing year, the exact amount in pounds by which the ACL was exceeded shall be deducted from the ACT for the corresponding monkfish stock on a pound-for-pound basis. The revised ACT and corresponding management measures (DAS and trip limits) will be implemented through a framework adjustment process in the second fishing year following the fishing year in which the ACL overage occurred.
Regulatory History
- Mid-1980s – Directed trawl and gillnet fisheries for monkfish grow rapidly.
- 1989 – European and Mediterranean monkfish species overfished, spurring greater demand for U.S. monkfish.
- Early 1990s – Fishing industry expresses concerns over dramatically increased fishing mortality rates, gear conflicts, growing directed trawl fishery, and a decline in size of landed monkfish.
- 1997 – Landings peaked at 62 million pounds (28,123 metric tons), with revenues of $35 million.
- 1997 – Atlantic Large Whale Take Reduction Plan was developed to reduce the likelihood of fishing gear entanglements of right, humpback, fin, and minke whales in the North Atlantic.
- 1998 – Harbor Porpoise Take Reduction Plan became effective and required gear modifications and area closures to reduce the likelihood of fishing gear entanglements of harbor porpoise.
- 1999 – Monkfish FMP was implemented which included a limited access permit program, a DAS management system, trip limits, and minimum size limits.
- 1999 – Amendment 1 approved to ensure compliance with essential fish habitat requirements of the Magnuson-Stevens Act.
- 2002 – Framework Adjustment 1 was disapproved by NOAA Fisheries. NOAA Fisheries instead published an emergency rule that implemented measures based upon the best available science to temporarily suspend the restrictive Year 4 default management measures that would have become effective May 1, 2002.
- 2003 – Framework Adjustment 2 modified the overfishing definition and implemented annual adjustments to the management measures.
- 2003 – Sea Turtle Conservation Final rule implemented a series of seasonal closures that prohibited the use of large mesh gillnets in Federal waters off the coast of Virginia and North Carolina to reduce the impact of the monkfish fishery on endangered and threatened species of sea turtles.
- 2005 – Amendment 2 addressed essential fish habitat, bycatch concerns, and issues raised by public comments.
- 2006 – Framework Adjustment 3 implemented to prohibit targeting monkfish on Multispecies B-regular DAS.
- 2007 – Interim management measures Framework 4 adopted in May to address overfishing while NOAA Fisheries conducted a stock assessment. Framework 4 was implemented in October to establish 3-year target total allowable catches (TACs), a target TAC backstop provision, and adjustments to DAS allocations and trip limits.
- 2007 – Amendment 3 was implemented as an Omnibus Amendment to standardize bycatch reporting methodology for monkfish and other fisheries.
- 2008 – NOAA Fisheries implemented Framework 5 to ensure the Monkfish Fishery Management Plan succeeds in keeping landings within the target total allowable catch levels. Measures include reduction in carryover DAS, reduction in bycatch or incidental catch limits, and revision in the biological reference points used to determine if the stock is overfished.
- 2008 – Framework 6 eliminated the backstop provision adopted in Framework Adjustment 4 to the FMP, October 2007.
- 2011 – Amendment 5 implemented a suite of measures including annual catch limits and accountability measures, measures to promote efficiency and reduce waste, and bring the biological reference points into compliance.
- 2011 – Framework Adjustment 7 implemented measures that were disapproved in Amendment 5 due to newly available science. Specifically, DAS allocations, trip limits, and an annual catch target for the Northern Area.
- 2013 – NOAA Fisheries implements an emergency action to suspend the monkfish possession limits in the Northern Fishery Management Area for monkfish permit categories C and D under a monkfish DAS.
- 2014 – Framework Adjustment 8 implemented measures to incorporate results of latest stock assessment, increase monkfish day-at-sea allocations and landing limits to better achieve optimum yield, and increase operational flexibility by allowing all limited access monkfish vessels to use an allocated monkfish-only day-at-sea at any time throughout the fishing year and Category H vessels to fish throughout the Southern Fishery Management Area.
- 2015 – Amendment 4 implemented Standardized Bycatch Reporting Methodology.
- 2016 – Framework Adjustment 9 eliminated the monkfish possession limit in the NFMA for Category C and D vessels fishing on both a Monkfish and NE Multispecies DAS, and revised the minimum mesh size and possession restrictions in the SFMA.
- 2017 – Framework Adjustment 10 implemented monkfish specifications for fishing years 2017–2019, and increased days-at-sea allocations and trip limits.
- 2020 – Framework Adjustment 12 implemented monkfish specifications for fishing years 2020–2022, and clarified the requirement for IVR vessels to call into a trip no more than an hour in advance of leaving port and the monkfish whole weight incidental possession limits in the Northeast multispecies exempted fisheries.
- Under Development – Framework Adjustment 13 is under development by the New England and Mid Atlantic Fishery Management Councils, and will include specifications for fishing years 2023–2025.
Science Overview
The most recent stock assessment for monkfish was an operational assessment in 2016, where the stocks in both the northern and southern areas were declared not overfished and overfishing was not occurring. The next assessment for monkfish is scheduled for 2019.
