| Abstract | Environmental DNA (eDNA) transforms the marine ecological research, by offering innovative non-invasive opportunities to understand the trophic links. This study explores the potential of eDNA in food web reconstruction and potential fishing zone (PFZ) validation, aiming to bridge intricate ecological insights with fisheries management. eDNA has already established itself as a powerful tool in fisheries and biodiversity monitoring, resource assessment, and conservation efforts, utilizing metabarcoding, next-generation sequencing technologies, and advanced bioinformatics tools. Integrating eDNA metabarcoding into food web reconstruction will enhance the understanding of trophic structure with higher taxonomic resolution to aid ecosystem-based management. This review elucidates the concepts of eDNA and explores its applications in food web studies and potential fishing zone (PFZ) dynamics. Additionally, the review presents a bibliometric analysis of the global publications related to eDNA, food web and marine fishes, scrutinizing the co-occurrence of these keywords in publications, underscoring the need to integrate the eDNA studies with these aspects to accurately derive insights into food web structure and fisheries potential. The review highlights the existing gaps in the effective use of this technique and underscores its immense potential to enhance efforts toward the sustainable utilization of marine resources and the advancement of the blue economy. |
