Seafood traceability is increasingly becoming a focal point to address the entry of illegally and unethically produced products into the supply chain. More and more, experts view full supply chain traceability and transparency as the only way to ensure against the continued entry of illegally or unethically produced seafood products into the seafood supply chain. Blockchain can be a significant part of the solution – providing the full transparency and traceability required to enable the market to reward responsible and ethical producers, and push those that are illegal and unethical out of the supply chain.
By providing this transparency and traceability, it can enable the market to both reward producers who engage in best practices, and exclude illegal and unethical producers. This report describes a WWF-led pilot to prove blockchain supply chain traceability for use in seafood traceability, specifically for tuna caught in a Fijian longline fishery. The purpose of the report is to provide a description of the work undertaken, to offer lessons learned, and to provide a potential roadmap for others who wish to develop blockchain supply chain solutions.
