WWF, Traceability principles for wild-caught fish products
https://wwfint.awsassets.panda.org/downloads/wwf_traceability_principles_for_wild_caught_fish_products_.pdf

Principle 1 — Essential Information
All wild-caught fish product traceability systems should provide rapid access to reliable information that is efficient
to assess the compliance of the fish product under consideration with all applicable legal requirements.
Principle 2 — Full Chain Traceability
All wild-caught fish product traceability systems should be able to provide “full chain” traceability from the point of catch to the point of final sale, and should be able to establish a verifiable and complete chain of custody/ownership of
the product as it moves through the supply chain.
Principle 3 — Effective Tracking of Product Transformations
All wild-caught fish product traceability systems should record tracking of product transformations and information on the location of product sufficiently to ensure that the legal origin of products can be readily established at the final point of sale, and that claims related to sustainability or fishing methods are readily verifiable.
Principle 4 — Digital Information and Standardized Data Formats
Wild-caught fish product traceability systems should employ electronic recording of data, labelling, and tracking in
standard data formats from point of capture to point of final sale.
Principle 5 — Verification
All wild-caught fish product traceability systems, and all claims based on them, must be subject to credible and transparent external verification mechanisms and regular independent audits, including effective governmental oversight and enforcement as well as, where applicable, credible third-party verification.
Principle 6 — Transparency and Public Access to Information
All wild-caught fish product traceability systems should be as transparent as possible and should provide consumers and other stakeholders the information needed to inform responsible choices
