On Monday 16 November 2026, the world’s largest fisheries management body sits down in Vilamoura, Portugal, to decide the future of the Atlantic’s most valuable fish. The International Commission for the Conservation of Atlantic Tunas (ICCAT) holds its 25th Special Meeting from 16 to 23 November 2026 — and in its 60th anniversary year, the decisions on the table could reshape how tuna, sharks and swordfish are caught across an entire ocean.
ICCAT manages the tunas and tuna-like species of the Atlantic Ocean and adjacent seas — skipjack, yellowfin and Atlantic bluefin among them — a fishery worth more than $5 billion a year, according to The Pew Charitable Trusts. It is the largest of the world’s regional fisheries management organisations (RFMOs), with 60 member governments and cooperating parties. What it decides in Vilamoura will be felt far beyond the Atlantic — including in India, whose own tuna fisheries are managed under a sister body, the Indian Ocean Tuna Commission (IOTC), which watches ICCAT’s precedents closely.

What is actually on the table in Vilamoura
The meeting is not a routine gathering. Four big items dominate the agenda, according to position papers published ahead of the meeting by The Pew Charitable Trusts (5 November 2026) and the International Seafood Sustainability Foundation (ISSF, 22 October 2026).
1. Science-based rules for tropical tunas, blue sharks and albacore
Since 2015, ICCAT has used “management procedures” — pre-agreed rules that set catch limits automatically based on how healthy a stock is, instead of leaving the number to an annual political negotiation. The approach already covers Atlantic bluefin and north Atlantic swordfish. In Vilamoura, members are expected to advance management procedures for blue sharks, tropical tunas and south Atlantic albacore so all three are ready for adoption next year. For a fishery worth over $5 billion, that shift from yearly bargaining to science-driven rules is the single biggest structural change on the agenda.
A higher yellowfin tuna catch limit is also reported to be on the table for this meeting, according to tuna trade publication Atuna (2 November 2026) — a decision that would directly affect the world’s second-most-caught tuna species by value.
2. High-seas boarding and inspection — the enforcement gap
Catch limits only work if they are enforced, and ICCAT has a known hole here: unlike the Western and Central Pacific Fisheries Commission and the North-East Atlantic Fisheries Commission (NEAFC), it still has no high-seas boarding and inspection scheme that lets member governments board and inspect fishing vessels in international waters. Members have discussed such a scheme for years. Pew’s assessment is blunt — ICCAT should finally adopt it this year, with transparent operating procedures and capacity-building so smaller fishing nations can take part in boardings.
3. Eyes on the water: observer coverage and electronic monitoring
ICCAT adopted electronic monitoring standards for purse-seine and longline fisheries in 2023. ISSF is now urging members to use those standards — cameras plus human observers — to lift observer coverage on large-scale longline vessels to an interim level of 20%. Better monitoring means better catch and bycatch data, and it is the foundation for every other decision on the agenda, from shark protections to seabird and sea-turtle bycatch measures.
4. Fish aggregating devices (FADs) and compliance
ISSF’s position statement for the meeting also covers FAD management, compliance processes, and monitoring, control and surveillance. Drifting FADs — floating rafts that attract tuna — are central to the tropical tuna purse-seine fishery, and how many can be deployed, and how they are tracked, is a live negotiation. The Eastern Pacific tuna body (IATTC) left several of these same questions unresolved at its own 2026 annual meeting, which makes the ICCAT outcome a test of whether Atlantic managers can do better.
Why this matters in India
India is not an ICCAT member — its Atlantic connection is indirect, and this post does not pretend otherwise. India fishes tuna in the Indian Ocean, where the Indian Ocean Tuna Commission (IOTC) is the responsible body, and India is an IOTC member. But ICCAT matters to Indian readers for three concrete reasons:
- It sets the global template. ICCAT is the oldest and largest tuna RFMO. Management procedures, electronic monitoring standards and inspection schemes adopted in the Atlantic are routinely studied — and often copied — by other tuna bodies, including the IOTC. A 20% observer-coverage benchmark or a working high-seas inspection scheme in the Atlantic becomes the reference point in Indian Ocean negotiations.
- It moves world tuna prices. Atlantic bluefin, yellowfin and skipjack are traded globally. Catch limits set in Vilamoura feed into the same world market where Indian tuna exporters sell. FAO’s State of World Fisheries and Aquaculture 2026 recorded a record global tuna catch of 9.3 million tonnes — when the biggest tuna body tightens or loosens supply, prices respond everywhere.
- It is the other half of the RFMO story. Just last week, NEAFC — the North-East Atlantic body — met in London to set 2027 catch limits for mackerel, blue whiting and herring. ICCAT is the same story on a much bigger stage: the world’s biggest tuna meeting, in the same month, deciding the rules for a $5-billion fishery.

How to follow the ICCAT meeting yourself
- Start with the official circular. ICCAT Circular 02258/2026 (1 April 2026) is the formal notice of the meeting — venue, dates, hybrid format and the Panel 1 pre-meeting. It is published on the ICCAT website.
- Check the ICCAT meetings page for the tentative agenda, timetable and meeting documents as they are published during the week.
- Read the two position papers. Pew’s 5 November 2026 article sets out the case for management procedures and high-seas inspection; ISSF’s 22 October 2026 priorities blog covers catch limits, FADs, electronic monitoring and bycatch in detail. Both are free to read.
- Watch for the outcomes after 23 November. ICCAT publishes adopted recommendations on its meeting documents portal. Fisheries India will carry a follow-up when the final decisions are published.
Frequently asked questions
What is ICCAT?
The International Commission for the Conservation of Atlantic Tunas, an intergovernmental body established in 1966 that manages tuna and tuna-like species in the Atlantic Ocean and adjacent seas. It also manages associated species such as sharks, swordfish, marlins, sea turtles and seabirds.
Is India a member of ICCAT?
No. India is a member of the Indian Ocean Tuna Commission (IOTC), the equivalent body for the Indian Ocean. India is not listed among ICCAT’s contracting parties or its four cooperators (Bolivia, Chinese Taipei, Suriname and Guyana). The Vilamoura decisions still matter in India because they set global tuna-market conditions and management precedents.
What is a management procedure?
A pre-agreed rule that calculates the catch limit from the assessed health of the stock, instead of negotiating the number from scratch every year. ICCAT has used them since 2015 for Atlantic bluefin and north Atlantic swordfish; the 2026 meeting should advance them for blue sharks, tropical tunas and south Atlantic albacore.
When will we know the results?
The meeting closes on Monday 23 November 2026. Adopted recommendations are published on the ICCAT meeting documents portal after the meeting.
