The Nature Conservancy (TNC) has initiated the Tuna Transparency Pledge with the goal of achieving 100% on-the-water monitoring of industrial tuna fishing vessels by 2027 to combat unsustainable and illegal fishing practices. Key signatories, including major retailers like Walmart and Albertsons Companies, seafood industry leaders such as Thai Union, and nations like Belize and the Federated States of Micronesia, have committed to enhancing supply chain transparency and adopting monitoring technologies. This initiative addresses the critical challenge of illegal, unreported, and unregulated (IUU) fishing, estimated to account for one in every five fish caught globally. The pledge underscores a collaborative effort among companies, governments, and NGOs to ensure seafood compliance, protect ocean resources, and support sustainable fisheries management, leveraging advancements in monitoring technologies like satellite radar to track global fishing activities.
