The Secret Rooms Where Your Seafood's Fate Gets Decided

Somewhere between a fishing vessel out on the water and a can of tuna in your grocery cart, a whole hidden system decides whether you should trust what's on the label. It runs on audits, vessel registries, and compliance reports that almost nobody outside the industry ever reads. It's the reason that a blue check mark on a package means anything at all.

What an RFMO Actually Is

The system starts with the RFMO, a regional fisheries management organization: a treaty-based body where countries with a stake in a fishery legally bind themselves to cooperate on how it's managed. One RFMO can oversee several different fisheries at once, and the countries involved can shift depending on which fishery is in question. These bodies exist because fish, unlike people, don't respect the borders humans draw. A tuna or a sea turtle can cross a dozen national jurisdictions in a single migration, so managing that species responsibly requires countries to manage it together. [VERIFY: some RFMOs are described as covering 45-plus member countries; confirm which RFMO and its current published membership count before publishing this figure again.]

Where does that cooperation actually happen? In windowless UN rooms in New York, at the FAO in Rome, and in what Andrew calls "boring ballrooms" in hotels around the world. Nearly the entire ocean falls under the jurisdiction of one RFMO or another. The skill that matters most in those rooms isn't legal expertise, it's listening: hearing what a country means behind what it's saying, since where a delegate stands often depends on where their country sits.

From a Negotiating Table to Your Dinner Table

Governance in these rooms isn't just paperwork. It's an agreed set of rules and somewhere to go when something goes wrong: a document that spells out what happens if a rule is broken, and what enforcement looks like when it is.

The payoff is that these governance decisions eventually reach your dinner table. The International Seafood Sustainability Foundation's (ISSF) transparency and accountability model is one clear example: participating seafood companies are audited annually, compliance reports are made public, and individual vessels are scored on public lists.

That audit trail feeds into market power through eco-labels. The Marine Stewardship Council's (MSC) blue check mark isn't symbolic. It carries real financial weight, which is why losing it can force real change. MSC suspended the Maine lobster fishery's certification twice: first in August 2020, then again on December 15, 2022, both tied to concerns over North Atlantic right whale protection under the Marine Mammal Protection Act and the Endangered Species Act. Notably, MSC's own auditors found only limited evidence that the fishery itself was responsible for the entanglements in question, meaning the suspension was as much about legal compliance status as it was about on-the-water risk. That pressure is part of why ropeless and reduced-rope lobster and crab gear is now moving from experimental to mainstream.

It also flows to retailers. Chains like Costco and Walmart won't put a product on the shelf that doesn't meet their own sustainability commitments, so transparency at the vessel level ends up shaping what's available at the store, not just what's technically legal to catch.

The Two Organizations Doing Two Different Jobs

It's worth being precise about who does what, because ISSF and MSC are often talked about as if they're the same thing.

ISSF does not certify fisheries. It works across the tuna supply chain, from vessel to processor to fishmonger to retailer, to build the evidence trail a fishery needs before MSC can certify it. Its assessments are conducted by an outside auditor, MRAG Americas [VERIFY: confirm spelling], not by ISSF itself, so it isn't grading its own homework. One of the tools it maintains is the ProActive Vessel Register (PVR), one of four public vessel lists ISSF runs, which publishes vessel-by-vessel compliance with specific conservation measures using a plain color code: a green check for implemented, a red mark for not implemented, and a circle for pending verification. Seafood buyers are named as a primary user group for that list.

As of ISSF's November 2024 compliance report, participating companies scored 99.1% compliance across 33 conservation measures covering things like product traceability, catch data submitted to RFMOs, and shark-finning and bycatch policies. That's 23 companies total, 17 of which met all 33 measures fully. At the individual vessel level, PVR-registered vessels scored a noticeably lower 76% compliance across 12 vessel-specific measures, like observer coverage and FAD (fish aggregating device) management, as of December 31, 2023. That gap between company-level policy and on-the-water vessel practice is worth naming, not glossing over. It's also getting better year over year, not staying flat.

MSC is the certifying body. It takes ISSF's underlying evidence, plus its own independent fishery-level science assessment, and turns it into the single blue label a shopper actually sees in the seafood aisle.

Neither organization replaces the other, and the two pieces don't work well apart. Compliance data buried in a PDF doesn't reassure anyone standing in a grocery store aisle. A label without credible, audited verification behind it is just marketing.

An Honest Caveat

This system isn't perfect. Not every MSC-certified fishery is free of disagreement about whether it should be certified, and not every RFMO-managed fishery is in ideal shape. The tuna industry itself still has compliance gaps to close, particularly at the vessel level. What this episode argues is that it's a step-by-step process, and the processes now in place, observer coverage requirements, FAD management rules, public compliance scoring, are moving that needle faster than they were two decades ago.

Takeaways:

• A regional fisheries management organization (RFMO) is a treaty-based body that turns "we should manage this fishery responsibly" into an enforceable, multi-country agreement.
• Eco-labels like MSC certification carry real financial weight. Losing one can force a fishery to change its practices, even when the science on the underlying risk is still ambiguous.
• ISSF does not certify fisheries. It builds the audited evidence trail, including annual compliance reports and the ProActive Vessel Register, that MSC draws on to certify them.
• As of ISSF's November 2024 compliance report, participating companies scored 99.1% compliance across 33 conservation measures, while PVR-registered vessels scored 76% compliance across 12 vessel-specific measures as of December 31, 2023.
• Transparency at the vessel level is what lets retailers hold to their own sustainability commitments, and what lets consumers trust a label instead of just a company's own claim.
