Freshwater ornamental fisheries represent an economically important sector characterized by complex supply chains and diverse market actors. However, inefficiencies associated with value distribution and supply chain structure remain insufficiently synthesized. This study presents a systematic literature review to examine how value chain distortions may influence economic efficiency in freshwater ornamental fisheries. The review followed PRISMA reporting guidelines and searched literature from Scopus, Web of Science, and Google Scholar covering publications from 2000–2025. Searches employed combinations of keywords related to ornamental fisheries, value chains, supply chains, market structure, and economic efficiency. Studies were included if they focused on freshwater ornamental fisheries and addressed economic dimensions such as value chain structure, market dynamics, pricing mechanisms, cost distribution, or efficiency-related outcomes. The initial search identified 72 records; after duplicate removal and title–abstract screening, 28 studies met the eligibility criteria and were included in the synthesis. Studies with indirect relevance, including broader fisheries and trade-related literature, were retained only when they contributed transferable insights into value chain structure or economic mechanisms. The synthesis indicates that freshwater ornamental fish value chains are frequently characterized by intermediary dominance, information asymmetry, operational losses, and institutional limitations that may contribute to unequal value distribution and reduced economic performance. Four categories of value chain distortion were identified: structural, operational, market, and institutional distortions. Based on these findings, a conceptual value chain distortion– efficiency framework is proposed to explain potential relationships between supply chain configurations and economic outcomes. The findings suggest the need for improved market transparency, stronger institutional coordination, and more efficient value chain arrangements to support sustainable development in freshwater ornamental fisheries. © 2026, Egyptian Society for the Development of Fisheries and Human Health.
