<p>Sustainability transitions in agri-food and aquaculture systems increasingly require economic paradigms that align environmental performance with value chain integration. This study conducts a bibliometric analysis of scholarly research addressing green, blue, and circular economy perspectives within agri-food and aquaculture value chains. Using bibliographic data retrieved from the Scopus database, the analysis applies cited reference co-citation, author keyword co-occurrence, temporal overlay, and citation burst techniques to examine the intellectual foundations, thematic development, and emerging research trajectories of the field. The results reveal a multi-paradigmatic knowledge base structured around environmental impact assessment, resource efficiency and value retention strategies, food system sustainability, digital transformation, aquaculture-oriented sustainability research, and governance-related frameworks. The thematic transition indicates a clear shift from production-centric and assessment-driven studies toward more integrated, system-level approaches that emphasize cross-stage coordination, circular resource flows, and technology-enabled sustainability solutions. Recent research increasingly focuses on data-driven value chain optimization, waste valorization pathways, ecosystem-based assessment, resilience, and sustainability challenges specific to aquatic and integrated production systems. By synthesizing intellectual structures and evolving research themes, this study clarifies how economic sustainability paradigms are operationalized across agri-food and aquaculture value chains. The findings provide a conceptual basis for positioning future research on sustainable production–consumption systems within broader green, blue, and circular economy transitions.</p>
