• This desk research explores current and prospective blockchain applications within the aquaculture sector. The primary aim is to create a theoretical foundation for deeper future research. Given the emerging nature of this topic, academic resources specific to blockchain use in aquaculture are limited. This paper reviews blockchain adoption in aquaculture, focusing on its role in tracking seafood supply chains and enhancing transparency and traceability. It highlights opportunities for advancing blockchain applications in aquaculture, including enhancing safety and quality control during critical stages such as transportation and distribution, as well as expanding its use for payments. This article provides a foundational understanding for stakeholders in aquaculture, policymakers and researchers, offering insights into the potential of blockchain to improve transparency, ustainability and efficiency within the sector. The findings also suggest directions for integrating advanced technologies, such as the Internet of Things (IoT), to further enhance the benefits of blockchain in aquaculture.
