This document ( Click here ) is a response to the National Ocean Council Committee on IUU Fishing and Seafood Fraud. We explain how the use of digital certificates can be used to verify that seafood is legal and in compliance with the myriad of laws and regulations related to the global trade of seafood and its entry into US commerce. An example rule set is presented to demonstrate how seafood products can be certified that they originate from regulated and legal fisheries, licensed vessels, and that the harvest was appropriately reported. We also address the specific questions from the Committee concerning data security, verification, collection, consistency and interoperability across agencies and stakeholders, and who would collect the data. The seafood supply chain is long, complicated, and generates a massive amount of data. To collect, monitor, and verify the data, a highly effective and efficient approach is needed to allow authorities to work closely with the industry and enable businesses to provide third-party digital certificates to prove that seafood is legal.
