VeriFish aims to offer a comprehensive framework of sustainability indicators, integrating data from trusted sources to assess environmental, social, and health-related factors in aquafood production, with the ultimate objective of allowing industry professionals and consumers alike to make informed decisions based on transparent, verifiable data. This deliverable follows D2.1 - Indicator Framework Defined, which defined a comprehensive suite of indicators that might be used to assess and communicate sustainability in the aquafood sector, focusing on fisheries, aquaculture, and human health. The indicator framework is built around three pillars, each addressing a critical dimension of sustainability to provide a holistic approach to assessing and communicating sustainability of aquafood. These pillars are: (a) Environmental, (b) Nutrition, and (c) Social and Economic, and serve as a backbone for sustainability assessment and communication. In contrast, this deliverable focuses on: (a) practical application of these indicators (Section 2), and (b) data sources that can be used for implementation of the framework (Sections 3,4 and 5). More specifically, we catalogue and describe key data sources, detailing their coverage, and relevance, and explain access and processing of these data. Moreover, we map data sources to specific indicators, clarifying how each source contributes to describing sustainability across the different pillars. A matrix is also presented that aligns data sources with the indicators in the framework (Section 6). Overall, the final version of the framework comprises 84 indicators distributed across the three main pillars, each further categorised into specific sub-pillars. In addition, more than 35 relevant data sources have been identified and described to support the application and monitoring of these indicators.
