Supply Chain Transparency
20 to 30 percent of seafood is mislabeled. IUU fishing generates $23 billion per year in fraud. The seafood supply chain has a structural accountability problem — and the technology to fix it already exists.
Oceana investigations across multiple countries and years consistently find 1 in 5 to 1 in 3 seafood products mislabeled by species or origin.
Illegal, unreported, and unregulated fishing generates an estimated $23 billion per year globally — the world's largest seafood supply chain fraud.
Typical imported seafood passes through 5 to 8 intermediaries before reaching the consumer. Each transfer is an opportunity for mislabeling or fraud.
How Mislabeling Happens
Seafood fraud is rarely a single actor making a deliberate choice to deceive. More often, it accumulates through a chain of small decisions — a relabeling at the processor, a missing record at the importer, a species name substitution that is technically legal in some markets and not others.
Escolar sold as "white tuna" or "butterfish"
Consumer deception; escolar causes gastrointestinal illness in some people
Farmed Atlantic salmon labeled as "Pacific wild salmon"
Higher price for lower-quality product; undermines sustainable fishery economics
Product mixed across origins at the processing facility
Legitimate traceability records become meaningless; fraud laundered through paperwork
Chinese-processed Vietnamese pangasius relabeled as US catfish
Circumvents tariffs, food safety standards, and import regulations
Technology Solutions
The tools for full supply chain transparency exist and are in use today. The barrier is not technical — it is adoption, particularly by intermediaries who benefit from opacity.
Immutable distributed ledger records each custody transfer. Once a batch is entered, the record cannot be altered. Wholechain uses the GDST 1.0 standard for international interoperability — a record created in Alaska is readable by a buyer in Japan.
Consumer-facing QR codes link to the full chain of custody record: vessel, captain, catch date, species, method, region, processor. The claim is verifiable by anyone with a phone — not just by a regulator with database access.
DNA barcoding can identify any fish species from a tissue sample with near-100% accuracy. Oceana uses it to document mislabeling. Some retailers now require it for high-risk species. Cost has dropped to under $15 per test.
Standards & Regulations
International interoperability standard for seafood traceability data. Ensures that a traceability record created by one system (Wholechain, SAP, etc.) can be read by another. Adopted by major retailers and brands.
The same barcode system used for retail products. GS1 identifiers applied to seafood lots enable automated tracking through supply chain software — the fish gets a unique ID that travels with it.
Requires recordkeeping of Key Data Elements (KDEs) and Critical Tracking Events (CTEs) for high-risk foods including seafood. Effective 2026 for most covered businesses. Effectively mandates supply chain traceability for US seafood.
FSMA 204: Key Data Elements
FDA's FSMA 204 requires tracking of specific data points at each Critical Tracking Event — harvest, landing, first processing, and each subsequent transfer.
- Species (scientific name)
- Product form
- Quantity and weight
- Vessel name and registration
- Catch area (FAO zone)
- Port of landing
- Catch date
- Landing date
- Processing date
- Captain / permit holder
- Processor / handler
- First receiver
What Full Transparency Looks Like
A fully transparent seafood product is one where every material fact is verifiable — not just claimed.
The PCS Model
Direct from Vessel Eliminates Fraud at the Source
The intermediaries where fraud occurs — the broker, the importer, the redistributor — exist because most fishing operations are not set up to sell direct. The fish leaves the vessel, enters a commodity stream, and loses its identity in the first transfer.
Direct-from-vessel sourcing eliminates the problem structurally. When a fish goes from vessel to processor to consumer without changing hands at an anonymous commodity level, there is no opportunity for species substitution or origin obfuscation. The chain of custody is short enough to verify.
This is not a technology solution — it is a supply chain architecture decision. The transparency comes from the structure, not the software, though software makes documenting and communicating that chain much easier.
