As of 2023, all federally permitted lobster vessels from Maine to Virginia must carry and operate a GPS tracking unit that transmits location data to government agencies once per minute.1Atlantic States Marine Fisheries Commission, Addendum XXIX to Amendment 3 to the American Lobster Fishery Management Plan; Addendum IV to the Jonah Crab Fishery Management Plan: Electronic Vessel Tracking for Federal Permit Holders, March 2022. These devices must be powered on at all times while the vessel is in the water, including when the vessel “is docked or being operated for personal use.”2Frank Thompson v. Carl Wilson, No. 25-1007, slip op. (1st Cir. Nov. 18, 2025). This policy poses a physical trespass of lobstermen’s property and raises serious privacy concerns for them, imposing the warrantless, suspicionless, and continuous government surveillance that the US Supreme Court has traditionally deemed unconstitutional under the Fourth Amendment.3United States v. Jones, 565 U.S. 400, 404 (2012); Riley v. California, 573 U.S. 373, 393 (2014); Carpenter v. United States, 585 U.S. 296, 313 (2018).
Refusing to comply can trigger severe economic and legal consequences—including financial penalties, jail time, and even federal moratoria that shut down entire state fisheries. In other words, the federal government can jeopardize the livelihoods dependent on fisheries should individuals or states choose not to follow its policy. This brief explains how the tracking mandate is implemented and enforced, the penalties for noncompliance, and the scope of the impacted lobster fishing industry.
Addendum XXIX (Add. XXIX) was adopted by the Atlantic States Marine Fisheries Commission (ASMFC), a federal interstate compact approved by Congress to manage Atlantic fishery resources.416 U.S.C. §§ 5101–5108. Add. XXIX required 10 Northeast and Mid-Atlantic states to adopt electronic tracking requirements for lobster vessels by December 15, 2023. The ASMFC adopted the policy to create a uniform vessel‑tracking regime across states, ostensibly to improve monitoring, decision-making, and enforcement.5Atlantic States Marine Fisheries Commission, Addendum XXIX.
The extent to which states are currently in compliance with the policy is unclear.6Atlantic States Marine Fisheries Commission, 2024 Winter Meeting Summary, January 2024, https://d23h0vhsm26o6d.cloudfront.net/3.-2024WinterMeetingSummary_revised.pdf. No final compliance determination has been made publicly available, and the ASMFC has not identified any state as being explicitly out of compliance. Furthermore, a 2024 review of the Interstate Fishery Management Plan (IFMP) finds that “all states appear to be in compliance with the requirements of the FMP.”7Atlantic States Marine Fisheries Commission, Review of the Interstate Fishery Management Plan for American Lobster (Homarus americanus): 2024 Fishing Year, November 2025, 17, https://asmfc.org/wp-content/uploads/2025/11/AmLobsterFMPReviewFY2024.pdf. This finding may not be reliable, however, given that state regulations in Connecticut and Virginia do not yet reflect compliant tracking requirements as of February 2026.8 The 2024 IFMP review reports that “Connecticut is currently in the regulatory process to implement electronic tracking device requirements.” Atlantic States Marine Fisheries Commission, Review of the Interstate Fishery Management Plan for American Lobster, 13.
According to state codes as of February 2026, eight states have adopted regulations requiring electronic tracking of lobster vessels in accordance with Add. XXIX.913-188 Code Me. R. ch. 25, § 98; 250-RICR-90-00-5.5.8; 7 Del. Admin. Code § 3755-4.0; COMAR 08.02.08.10(G); 322 Mass. Regs. Code § 7.11; N.H. Admin. Code § Fis 612.01; N.J. Admin. Code § 7:25-14.16(12); 6 N.Y.C.R.R. § 38.3. No state has adopted specific penalties for this tracking requirement. Rather, states’ general penalties for their fishery laws and rules apply to violations of this policy. Violating these regulations constitutes a misdemeanor across the relevant states, and possible punishments include fines of hundreds to thousands of dollars, suspension of an individual’s license and permit, and potential jail time of 20 days to two and a half years.1012 Me. Rev. Stat. Ann. § 6204; 7 Del. C. § 1304(a), (c), (f); Conn. Gen. Stat. §§ 26-157a–26-157d; COMAR 08.02.01.03; N.Y. Envtl. Conserv. L. §§ 71-0919, 0925 (McKinney’s 2024); MD Code, Natural Resources § 4-1201; Mass. Gen. Laws ch. 130 § 2; N.H. Rev. Stat. § 211:17; N.J.A.C. 7:25–14.20(g)–(j); 20 R.I. Gen. Laws 1956, § 20-1-16(a); Thompson v. Wilson, No. 25-1007, 8 n. 4 (1st Cir. 2025); 4 VAC 20-110-70; VA Code Ann. § 18.2-11. The general penalties of Delaware, Massachusetts, Maryland, Rhode Island, and Virginia include the possibility of imprisonment for violating relevant fishery laws and regulations.
Add. XXIX is part of a federally enforced fishery management plan.1116 U.S.C. §§ 5104–5106. Under federal law, the ASMFC is authorized to adopt fishery management plans and regulations and deem states noncompliant if they fail to implement and enforce them.1216 U.S.C. §§ 5104–5105. The secretary of commerce can then “declare a moratorium on fishing in the fishery in question within the waters of the noncomplying state.”1316 U.S.C. § 5106(c)(1).
As Table A1 in the appendix illustrates, moratoria function primarily as a deterrent rather than a regularly used enforcement tool. Since 1993, the federal government has declared 11 moratoria, all of which were withdrawn or cancelled before their effective dates, including on American lobster in 2001. Table A1 documents each of these declarations and estimates each threatened fishery’s economic value. The federal government is not shy about using declarations of moratoria to threaten valuable fisheries to enforce ASMFC rules.
If noncompliance were to trigger a moratorium on American lobster fishing, the economic consequences would be severe. Table 1 shows the economic value of the American lobster fisheries subject to this tracking requirement. These figures illustrate just how much is at stake if a state refuses to require surveillance of its lobstermen. A prohibition on harvesting a species would, for some states, halt tens or even hundreds of millions of dollars in annual revenue. The possibility of federal enforcement therefore serves as powerful leverage, pressuring states to implement ASMFC rules even when doing so requires compliance with a tracking mandate that raises Fourth Amendment concerns.

Although no ASMFC moratorium has ever taken effect, Canada’s 1992 cod moratorium shows what an enforced fishery shutdown looks like.14Department of Fisheries and Oceans Canada, Report to Parliament by the Minister of Fisheries and Oceans Respecting the Administration of the Atlantic Fisheries Restructuring Act for Fiscal Year 1992–93 (Ottawa: Communications Directorate, Department of Fisheries and Oceans, 1994), https://waves-vagues.dfo-mpo.gc.ca/Library/361019eng.pdf. The moratorium resulted in the “single largest mass layoff in Canadian history,” immediately putting about 12 percent of the province of Newfoundland and Labrador out of work. High levels of unemployment and emigration continued years after the moratorium took effect.15Jenny Higgins, “Economic Impacts of the Cod Moratorium,” Newfoundland and Labrador Heritage Website, 2008, https://www.heritage.nf.ca/articles/economy/moratorium-impacts.php.
A fishery moratorium, economist Brian Shin and coauthors note, is an “extreme, even ‘draconian’ measure” that is likely to impose “higher food prices and hunger” on communities dependent on fishing and therefore “should be reserved only for the most dire of circumstances.”16Brian B. Shin, Jon M. Conrad, and C.-Y. Cynthia Lin Lawell, “On the Optimality of a Fishery Moratorium” (working paper, Cornell University, Ithaca, NY, March 2020), 2. At the individual level, violating an ASMFC-imposed moratorium carries steep consequences: A person may face civil penalties, fines of up to $100,000, or imprisonment for up to six months.1716 U.S.C. §§ 1858(a), 1859(b).
Proponents of Add. XXIX argue that lobstermen forfeit their Fourth Amendment rights because they engage in unusually sensitive work.18Frank Thompson v. Carl Wilson, No. 25-1007, slip op. at 18, 21 (1st Cir. Nov. 18, 2025). But lobster fishing is not one of the “closely regulated industries” outlined in the Supreme Court’s ruling in Patel (2015) that “have such a history of government oversight that no reasonable expectation of privacy . . . could exist.”19The four closely regulated industries are liquor sales, firearms dealing, mining, and automobile junkyards. City of Los Angeles v. Patel, 576 U.S. 409, 424 (2015); Marshall v. Barlow’s, Inc., 436 U.S. 307, 313 (1978). Furthermore, no evidence exists that the lobster fishing industry represents “a clear and significant risk to the public welfare.”20City of Los Angeles v. Patel, 576 U.S. 409, 424 (2015).
As of 2017, there were 3,288 active federal lobster permits.21NOAA Fisheries, “American Lobster – Permitting Information,” last updated August 21, 2025, https://www.fisheries.noaa.gov/permit/american-lobster-permitting-information. That is over 3,000 vessels and livelihoods that are subject to constant governmental tracking of their activities. In Maine, for example, a moratorium would impact more than 6,500 jobs and almost $1 billion in economic output generated by lobster fishing.22Ryan Wallace and Charles S. Colgan, The Economic Impacts of the Maine Seafood Sector (Middlebury Institute of International Studies at Monterey and Maine Center for Business and Economic Research, January 2023), 13, https://www.seamaine.org/wp-content/uploads/2023/03/FINAL-SEAMaine-Economic-Impact-Analysis-Report-2.pdf; Melissa Waterman, “Lobster’s Claw-Hold on Maine Is Strong,” last updated July 6, 2022, https://www.islandinstitute.org/working-waterfront/lobsters-claw-hold-on-maine-is-strong/. If individuals do not want to be under constant surveillance, they face penalties; if states do not want to enforce such a policy, they face the threat of federal moratoria on their respective fisheries. Policymakers interested in maintaining the economic vitality of fisheries and protecting the Fourth Amendment rights of industry participants should consider repealing this surveillance rule.
