Chairman Webster, Ranking Member Carbajal, and Members of the Subcommittee, on behalf on the
Congressional Research Service (CRS), thank you for this opportunity to appear before you. I am Caitlin
Keating-Bitonti, an Analyst in Natural Resources Policy. The Subcommittee requested that CRS testify
about the United States Coast Guard’s role in the at-sea enforcement of living marine resource laws and
international agreements as it pertains to illegal, unreported, and unregulated (IUU) fishing. In accordance
with our enabling statutes, CRS takes no position and makes no recommendations on legislative or policy
matters. My testimony draws on my own area of specialization at CRS—federal ocean science policy and
relevant international agreements—and on the input of other CRS colleagues who cover other issues often
associated with ocean policy, including IUU fishing.
Illegal, Unreported, and Unregulated (IUU) Fishing
IUU fishing is an ongoing, multi-faceted global issue that affects the ocean ecosystem and the sustainable
management of living marine resources, both within areas of national jurisdiction and on the high seas.1
IUU fishing can impact the accuracy of the data needed to inform fisheries conservation and management
decisions, thereby adding to overfishing and threatening food security in certain regions. Furthermore, the
difficulty in regulating fishing vessels on the high seas may allow some of the vessels involved in IIU
fishing to engage in other transnational crimes, such as labor abuses, drug smuggling, and human
trafficking.2
According to the U.S. Coast Guard, IUU fishing has replaced piracy as the leading global maritime
security threat.3 IUU fishing generally refers to fishing activities that violate national laws or international
fisheries conservation and management measures. The international definition of IUU fishing is provided
in the Food and Agriculture Organization (FAO) of the United Nations International Plan of Action for
IUU fishing.4 The International Plan of Action for IUU fishing was developed as a voluntary instrument
within the framework of the FAO Code of Conduct for Responsible Fisheries, which has the general
objective of promoting sustainable fisheries.5 In general,
• Illegal fishing refers to fishing activities conducted in contravention of applicable laws
and regulations, including those laws and rules adopted at the regional and international
level.
• Unreported fishing refers to those fishing activities that are not reported or are
misreported to relevant authorities in contravention of national laws and regulations or
reporting procedures of a relevant regional fisheries management organization (RFMO).
RFMOs are treaty-based international bodies composed of nations that share an interest
in the management and conservation of fisheries in specific geographic areas of the high
seas.

• Unregulated fishing refers to fishing activities occurring in areas, or fishing for fish
stocks,6 for which there are no applicable conservation and management measures and
where such fishing activities are conducted in a manner inconsistent with a nation’s or
entity’s responsibility under international law. Unregulated fishing also includes fishing
activities conducted by vessels without nationality within the geographic boundaries of
an RFMO, or by vessels flying a flag of a nation not a party to the RFMO with authority
in that area.7
IUU fishing undermines national and regional efforts to conserve and manage fish stocks.8 FAO estimates
that one in five (or 20%) fish caught around the world comes from IUU fishing and, in some regions, such
as in West Africa, it can be as high as 40%.9
Illegal fishing can entail fishing for nonpermitted species, fishing above management quotas, and fishing
out of season. These illegal fishing behaviors can contribute to stocks being fished at biologically
unsustainable levels (i.e., at rates greater than species can replenish themselves). FAO estimates that the
percentage of stocks fished at biologically unsustainable levels has been increasing since 1970s, from
about 10% in 1974 to about 35% in 2019.10 In particular, in 2019, approximately 77% of catch off the
Pacific coast of South America occurred at biologically unsustainable levels.11
By its very nature, IUU fishing is difficult to quantify, but there is general global consensus that the
impacts of IUU fishing have far-reaching negative consequences.12 First, IUU fishing undermines the
sustainable management of fishery resources—resources that provide both food security and
socioeconomic stability in many parts of the world. Developing countries that depend on fisheries for
food security and export income are most at risk from IUU fishing.13 For example, according to a 2022
report by the FAO, aquatic foods provide at least 20% of the average intake of animal protein for 3.3
billion people.14 IUU fishing can inhibit lawful access to this protein source.
A second negative consequence of IUU fishing is that it provides an unfair advantage to entities that
engage in these activities.15 For example, vessels conducting IUU fishing avoid operational costs by not
complying with regulatory requirements and may earn more revenue by exceeding harvest limits.
Conversely, those fishing legally may be harmed by lower catch rates and higher associated fishing costs.
IUU fish in the marketplace can put legal fishers at an economic disadvantage and cause them to lose

6 NOAA Fisheries defines a stock as “a part of a fish population usually with a particular migration pattern, specific spawning
grounds, and subject to a distinct fishery. A fish stock may be treated as a total or a spawning stock. Total stock refers to both
juveniles and adults, either in numbers or by weight, while spawning stock refers to the numbers or weight of individuals that are
old enough to reproduce.” NOAA, NOAA Fisheries Glossary, p. 49.

revenue. According to FAO, IUU fishing catches millions of tons of fish every year,16 and experts have
calculated that IUU costs the global economy up to tens of billions of dollars every year.17
Experts note that international cooperation is necessary to manage many fish stocks because some species
move among different national zones of jurisdiction and the high seas. However, actions to combat IUU
fishing activities are often hindered by the large areas in which fishing takes place, the lack of resources
for adequate enforcement, weak governance institutions, and inadequate international cooperation. On the
high seas, vessels are subject to the laws of their flag state—the flag state of a vessel is the nation of
jurisdiction under whose laws the vessel is registered or licensed and is deemed the nationality of the
vessel.18 Vessels are also subject to the applicable rules established by international agreements and
conventions to which their flag state is a party. The expectation is that all fishing nations exercise
responsible flag state control over their vessels, including their distant water fleets operating on the high
seas.
China’s Role in the Exploitation of Global Fisheries
IUU fishing occurs throughout the world, and according to the U.S. International Trade Commission a
portion of the seafood entering the United States reportedly is obtained from IUU fishing activities. The
U.S. International Trade Commission estimated that in 2019 about $2.4 billion (or 11%) worth of U.S.
seafood imports were products of IUU fishing, of which about $204.3 million were obtained from
Chinese IUU fishing.19
China is one of the world’s largest seafood importers, having imported approximately 4.1 million metric
tons of seafood in 2022.20 Unlike other large importers such as the United States and Japan, the majority
of seafood that China imports is not consumed in country.21 Recent estimates have found that nearly 75%
of all fish imported by China never makes it to the Chinese market, but instead is re-exported into the
global market.22
In recent years, the IUU Fishing Index—a collaboration between Global Initiative Against Transnational
Organized Crime, a non-governmental organization, and Poseidon Aquatic Resource Management Ltd., a
private fisheries and aquaculture consultancy—has consistently identified China as the worst-performing
nation overall in combating IUU fishing.23 (The IUU Fishing Index analyzes the performances of 152
nations.)24

China has the world’s largest fishing fleet, with an estimated 564,000 vessels, and in 2020 was the top
combined producer of marine and inland water catches, making up nearly 15% of global catches.25 China
also has the largest distant water fishing fleet in the world,26 with an estimated 2,900 to 3,400 vessels
according to the U.S. International Trade Commission.27 Distant-water fishing is the practice of operating
fishing fleets outside of your own nation’s Exclusive Economic Zone (EEZ), the zone that extends 200
nautical miles seaward of a coastal nation’s shoreline.28 Distant water fishing fleets operate either on the
high seas or foreign EEZs. Overfishing and depleted coastal fish stocks in its national waters have led
China’s fishing industry to develop a distant-water fishing fleet.29
China’s distant water fishing fleets are alleged to be increasingly engaging in IUU fishing. A 2022 report
by the Environmental Justice Foundation estimates that 95% of Chinese distant water fishing crews have
witnessed some form of illegal fishing, including the removal of shark fins and the targeting of
endangered and protected marine life.30 In 2021, the National Oceanic and Atmospheric Administration’s
(NOAA’s) National Marine Fisheries Service (NMFS) issued China a negative certification for IUU
fishing, under the authorities of the High Seas Driftnet Fishing Moratorium Protection Act (16 U.S.C.
§1826j(d)).31 China denied all allegations made by NMFS.32
Like many governments with industrial-scale fishing operations, the Chinese government provides
financial and policy support to its fishing industry, including its distant water fishing fleet.33 This support
takes a variety of forms, including fuel subsidies, vessel upgrading/replacement subsidies, and tax
incentives. Some analysts argue that some types of distant water fishing would be unprofitable for
Chinese vessel operators without government subsidies.34
China has adopted some policies to address IUU fishing. However, a 2021 report estimated that at least
183 Chinese distant water fishing vessels, some of which are government-owned or -operated, are
involved in IUU fishing, suggesting that the China is not holding its vessels accountable for engaging in
IUU activities.35 Under the U.N. Convention on the Law of the Sea, which China ratified in 1996, the flag
state has exclusive jurisdiction over vessels flying its flag on the high seas.36

U.S. Government Initiatives Aimed at Combating IUU Fishing
Over the past two decades, successive U.S. administrations and Congresses have recognized that IUU
fishing poses a threat to national and regional security and have taken a number of actions to combat IUU
fishing broadly. These actions attempt to influence the behavior of foreign fishing fleets through
international agreements, organizations, and trade, because most IUU activities occur outside of U.S.
jurisdiction.37
The United States works with other fishing nations through RFMOs and other multilateral international
agreements to sustainably manage high seas fisheries and address IUU fishing globally. Several federal
agencies, including the U.S. Coast Guard, NOAA, the Department of Defense, and the Department of
State, engage in various efforts to combat IUU fishing on the high seas and in the EEZs of partner
nations. The efforts of these federal agencies include establishing strategic partnerships; improving
enforcement tools, such as high seas boarding and inspection; identifying and sharing information about
countries that have fishing vessels engaged in IUU fishing activities; and assisting partner nations develop
and maintain their own counter IUU fishing capacity, among other lines of effort.38
In 2019, the Maritime Security and Fisheries Enforcement Act (Division C, Title XXXV, Subtitle C of
P.L. 116-92, 16 U.S.C. §§8001 et seq.), commonly known as the Maritime SAFE Act, passed in the
National Defense Authorization Act for Fiscal Year 2020. The Maritime SAFE Act seeks to support a
whole-of-government approach to counter IUU fishing, improve data sharing, support efforts to counter
IUU fishing in priority regions around the world, increase global transparency and traceability across the
seafood chain, improve global enforcement operations against IUU fishing, and prevent the use of IUU
fishing as a financing source for transnational crime.39 The Maritime SAFE Act also established the
Interagency Working Group on IUU Fishing to support and coordinate a government-wide effort to
address IUU fishing globally. The IWG on IUU Fishing is made up of representatives from 21 federal
agencies and is currently chaired by a representative from the Department of State, with representatives
from the National Oceanic and Atmospheric Administration and U.S. Coast Guard serving as Deputy
Chairs.40
U.S. Coast Guard’s Role in Addressing IUU Fishing
The U.S. Coast Guard is a multi-mission maritime service with the authority to conduct maritime law
enforcement operations, including operations aimed at combating IUU fishing activity.41 The U.S. Coast
Guard enforces U.S. and international living marine resources laws in the U.S. EEZ and in key areas of
the high seas, and works with NOAA, Department of Defense, and Department of State to provide whole-
of-government approach to addressing IUU fishing.42
The U.S. Coast Guard is the lead U.S. agency for at-sea enforcement of fishery conservation on the high
seas.43 On the high seas, RFMOs manage and conserve fish stocks of a particular species or group of
species within a particular geographic area. The 1995 U.N. Fish Stocks Agreement provides an enhanced

37 Actions to combat IUU fishing have included enforcement agreements with partner countries, trade monitoring,
implementation and enforcement of international treaties, and broad efforts to promote resource sustainability.

framework for RFMOs’ conservation and management of transboundary fish stocks.44 Under the 1995
U.N. Fish Stocks Agreement, party nations are obligated to regulate “the activities of vessels flying their
flag which fish for such stocks on the high seas.”45 In addition, the agreement gives party nations the right
to monitor and inspect vessels of other nation parties to ensure compliance with internationally agreed
fishing regulations, including regulations established by RFMOs. Violations of RFMO conservation
measures are generally considered IUU fishing.
Both the Interagency Working Group on IUU Fishing’s National 5-Year Strategy for Combating Illegal,
Unreported, and Unregulated Fishing and the U.S. Coast Guard’s IUU Fishing Strategic Outlook
Implementation Plan identify strategies used by the U.S. Coast Guard to counter IUU fishing on the high
seas, such as at-sea operations, use of vessel tracking data to identify vessels suspected of IUU fishing,
and cooperation in partner nation capacity-building exercises.46
U.S. Coast Guard At-Sea Operations
The U.S. Coast Guard identifies instances of IUU fishing through its at-sea operations. On the high seas,
under the authority of some RFMOs, U.S. Coast Guard law enforcement officials may conduct law
enforcement boardings and investigations of fishing vessels suspected of IUU fishing.47 U.S. Coast Guard
law enforcement officials may also randomly board other vessels as a means to deter IUU fishing activity.
If a U.S. Coast Guard patrol not directly related to IUU fishing suspects a vessel of IUU fishing, the U.S.
Coast Guard may provide relevant information to other U.S. federal agencies (e.g., NMFS) for further
investigation. The U.S. Coast Guard patrol may also report the suspect vessel to the relevant RFMO to
share information about the vessel with other member states of the RFMO to aid in the tracking of the
vessel.
The U.S. Coast Guard reports IUU fishing violations identified through at-sea patrol to RFMOs, which
alert the vessels flag state. On the high seas, vessels are subject to the laws of their flag state. The U.S.
Coast Guard shares information about the vessels it identifies as having participated in IUU fishing to
relevant U.S. federal agencies to inform IUU fishing vessel lists,48 which may trigger port control
measures, among other actions.49
Experts consider high seas boarding and inspection of vessels to be effective approaches for fisheries law
enforcement and for identifying vessels engaged in IUU fishing.50 According to the U.S. Government
Accountability Office (GAO), from 2016 through 2020, the U.S. Coast Guard boarded and inspected 227

fishing vessels on the high seas within the boundaries of RFMOs to which the United States is a party.51
During these inspections, the U.S. Coast Guard found 90 potential violations of RFMO fishery
conservation and management measures.52 The information obtained by the U.S. Coast Guard through
vessel boardings and inspections can inform U.S. diplomatic engagements with foreign nations. However,
only a subset of RFMOs have high seas boarding and inspection measures. The Interagency Working
Group on IUU Fishing identified the need for more RFMOs to adopt high seas boarding and inspection
measures.53 According to GAO, the U.S. Coast Guard, Department of State, and NOAA are working to
promote the adoption of high seas boarding and inspection measures in all RFMOs to which the U.S. is a
member.54
U.S. Coast Guard Use of Vessel Tracking Data
The scale of the ocean environment enables some fishing fleets to conduct IUU fishing activity unnoticed
and presents law enforcement challenges. The International Maritime Organization and other
management bodies require large ships, including many commercial fishing vessels, to broadcast their
position with an automatic identification system (AIS).55 In addition to broadcasting the location of the
vessel, AIS devices also broadcast information about the identity, course and speed of the vessel. Radio
stations and satellites pick up this information, making vessels trackable even in the most remote areas of
the ocean.
The U.S. Coast Guard analyzes vessel tracking data to identify movement patterns that may be indicative
of IUU fishing activity.56 Fishing vessels that “go dark” by ceasing to broadcast position information may
suggest that these vessels are engaging in IUU fishing activities. Research conducted by NOAA, the
University of Santa Cruz, and Global Fishing Watch found that vessels most often go dark while fishing
next to EEZs with contested boundaries, fishing in EEZ with limited management oversight, and during
the transfer of fish between fishing vessels and refrigerated cargo vessels.57 The U.S. Coast Guard
analyzes vessel tracking data to help guide at-sea patrol operations to target suspect vessels.
In its IUU Fishing Strategic Outlook Implementation Plan, the U.S. Coast Guard acknowledged that it
will continue to advance and implement innovative technology to counter IUU fishing and to expand
multilateral fisheries enforcement cooperation with partner nations.58
U.S. Coast Guard Efforts to Build Capacity for Partner Nations
The U.S. Coast Guard works with partner nations to develop and maintain their own counter IUU fishing
capacity, including the enforcement of their own fisheries conservation measures and the investigation
and prosecution of their own fishing fleets suspected of IUU fishing. According to its IUU Fishing
Strategic Outlook Implementation Plan, the U.S. Coast Guard aims to create regionally based

international fisheries law enforcement symposiums for foreign partners, support expanded unclassified
information sharing about illicit operations, and add counter-IUU fishing measures to existing bilateral
agreements, among other initiatives to combat IUU fishing.59
One strategy used by the U.S. Coast Guard to help foreign partners build capacity for counting IUU
fishing is through shiprider agreements.60 Shiprider agreements authorize a law enforcement official of
one party to embark on a law enforcement vessel, or aircraft, of the other party and exercise certain
authorities. U.S. shiprider agreements are designed to allow U.S. law enforcement officials, typically U.S.
Coast Guard law enforcement officials, to assist partner nations in combating various illicit maritime
activity, such as IUU fishing. In general, U.S. bilateral shiprider agreements allow maritime law
enforcement officers of a partner nation to embark on vessels (and/or aircraft) of the U.S. government.
The presence of a shiprider on board a U.S. government vessel allows the vessel to enforce the laws and
regulations of the partner nation, including the boarding and inspection of suspect vessels, within the
partner nation’s designated territorial sea or exclusive economic zone. Certain shiprider agreements also
allow U.S. government vessels with embarked shipriders to pursue flag ships of the party on the high
seas.
Not all U.S. bilateral shiprider agreements include counter-IUU fishing provisions. According to GAO,
the United States has entered into 15 shiprider agreements that address IUU fishing.61 One priority of the
Interagency Working Group on IUU Fishing is for the U.S. government to establish new bilateral
shiprider agreements that have counter-IUU fishing provisions with countries located within priority
regions and to add counter-IUU fishing provisions to existing shiprider agreements.62
The U.S. Coast Guard also coordinates with the Department of Defense in their at-sea exercises. Some of
these exercises may be designed to help partner nations build maritime security capacity, including their
capacity to address IUU fishing in their territorial waters and IUU fishing committed by their flagged
vessels. For example, the U.S. Coast Guard and U.S. Africa Command collaborated to enhance partner
