Deep-Sea Fisheries: The Ocean's Untapped Frontier

Deep-sea fisheries represent an emerging frontier for marine resource exploration and sustainable fisheries development, offering potential opportunities to diversify seafood production, strengthen the blue economy and support fishers’ livelihoods. Despite their considerable ecological and economic significance, deep-sea ecosystems remain relatively unexplored, and many of their living resources are inadequately documented and underutilised. India, with its extensive coastline, vast EEZ area and diverse marine ecosystems, provides considerable potential for the development of deep-sea fisheries. However, the exploitation of these resources is constrained by limited biological information, technological challenges, high operational costs and uncertainties regarding stock status and ecosystem resilience. This article examines the potential of India's deep-sea fisheries, highlighting resource diversity, commercially important and non-conventional species, technological advancements, and the role of national initiatives such as the Deep Ocean Mission in advancing scientific exploration. Furthermore, international conservation frameworks, national policy measures and emerging technological approaches are considered in the context of responsible utilization of deep-sea resources. The future development of deep-sea fisheries requires an integrated, science-based strategy encompassing resource assessment, species-level identification, stock evaluation, selective fishing technologies, value addition, and ecosystem-based fisheries management.
