AbstractThis concept and review study introduces a baseline research work on PROfitable deep-sea Fishing zone Track (PROFIT) for the north Indian Ocean. The primary objective of PROFIT is to identify and track profitable deep-sea fishing zones (DFZs) using a suite of oceanographic parameters such as sea surface temperature, chlorophyll-a concentration, sea level anomaly, currents, upwelling, mixed layer depth, ocean net primary productivity (NPP), euphotic zone, and thermal front etc. These environmental proxies are important to understand the link between marine productivity with fishery resources and the oceanic environment. By employing data-driven, multi-criteria threshold-based analyses, the approach classifies the fishing zones into high, medium, and low probability areas of fish availability, thereby improving spatial targeting of fishing efforts. The PROFIT framework also emphasizes the identification of ⿿on-front⿿ and ⿿back-front⿿ zones associated with thermal and productivity gradients, enabling enhanced tracking of DFZs. This has the potential to significantly reduce search time and fuel consumption, thereby increasing profitability for fishers. Additionally, optimizing fishing routes based on environmental conditions can lower operational costs and carbon emissions, while supporting higher catch efficiency, food security, and the economic resilience of coastal communities. Scientific advisories based on such data-driven methods can minimize overfishing in low-productivity areas and promote sustainable harvesting practices. These insights also support policy development, long-term ecosystem monitoring, and the formulation of predictive models for fish resource availability. Ultimately, the PROFIT concept provides a foundational step toward sustainable fishery management and marine conservation in the North Indian Ocean region.
