When you pick up a can of tuna at the grocery store, you might wonder where that fish actually came from. Was it caught sustainably? Did it travel through legitimate channels? The tuna supply chain involves multiple players across different countries, creating a complex web where information gets lost or fragmented along the way.
This complexity creates real problems for businesses and consumers alike. Poor tuna traceability can lead to mislabeling scandals, regulatory violations, and the unintentional introduction of illegally caught fish into legitimate markets.
The complex journey from ocean to plate
The tuna supply chain spans multiple oceans and involves numerous stakeholders. A single tuna could be caught in the Pacific, transferred to a carrier ship, processed in one country, and distributed through traders and retailers in several others before reaching your local store.
Each handoff creates potential gaps in information:
- Fishing vessels may operate under different flag states than where they land their catch, creating jurisdictional complexity in documentation
- Processors could receive tuna from multiple sources and combine them into single batches, making individual fish tracking impossible
- Traders might handle products from various processors, adding another layer where details can be lost
- Retailers often source from multiple distributors, further fragmenting the chain of custody
Each participant may only have visibility into their immediate suppliers and customers. When fishing methods like longlining involve transshipment at sea, the complexity multiplies further, making end-to-end traceability nearly impossible with traditional paper methods.
Why traditional tracking methods fall short
Most tuna supply chains still rely on paper-based documentation and manual record-keeping, creating several blind spots that make verification nearly impossible:
- Paper documentation vulnerabilities – Documents can be lost, damaged, or falsified, and often don’t capture relevant details about origin or handling
- Manual data entry errors – Human mistakes compound as products move through the supply chain, degrading data quality at each step
- Post-processing tracking limitations – Many systems only begin after fish reach processing facilities, missing critical at-sea origin information
- Fragmented data systems – Different stakeholders use separate databases without standardized formats, making information sharing nearly impossible
Without real-time data capture from the point of harvest, companies are essentially reconstructing a complex journey using incomplete puzzle pieces. This fragmentation becomes particularly problematic during audits when regulators need to quickly trace products back to their origins.
The hidden costs of poor tuna traceability
When tuna traceability fails, the consequences extend far beyond record-keeping problems:
- Regulatory penalties and fines – Mislabeling scandals regularly result in substantial fines when DNA testing reveals products don’t match their labels
- IUU contamination risks – Unknowingly introducing illegal, unreported, and unregulated fish can trigger lawsuits, regulatory investigations, and millions in lost revenue
- Costly recalls and investigations – Traceability failures force expensive product recalls and lengthy regulatory reviews that disrupt operations
- Long-term brand damage – Consumer trust erosion affects future sales as customers switch to competitors offering better transparency
What begins as a documentation problem can quickly escalate into a crisis affecting multiple product lines and key customer relationships. In an increasingly conscious marketplace, the ability to verify sustainability and ethical sourcing has become a competitive necessity rather than a nice-to-have feature.
How SmarTuna solves tuna traceability challenges
SmarTuna addresses these challenges through a comprehensive digital platform that captures data from the moment fishing begins. The system uses satellite VMS and AIS technology to track vessel activity in real time, providing immediate verification of fishing locations and methods.
The platform assigns a unique Raw Material ID at port discharge, digitally linking origin, composition, and verification criteria before processing begins. This first-mile approach ensures that critical information about how and where tuna was caught is preserved throughout the entire supply chain journey.
SmarTuna automatically pulls data from more than 15 regulatory and certification databases, including RFMO registries, ISSF PVR, MSC CoC, and IUU blacklists. This automated verification eliminates manual checking and provides instant compliance validation, with all documents stored digitally per batch for full track-and-trace capability.
Built on GS1-EPCIS standards and fully GDST-compatible, the platform ensures consistent data exchange across all supply chain participants. Companies can access audit-ready documentation instantly, while consumers can verify product stories through QR-accessible Digital Product Passports—helping businesses reduce recalls, mislabeling risks, and regulatory violations while building verifiable trust with buyers and partners.
