India's blue economy policy envisages the responsible use of ocean resources for economic growth and sustainability. The Indian National Centre for Ocean Information Services (INCOIS) contributes to this vision by supporting the fishing industry through its Potential Fishing Zone (PFZ) advisory services. PFZ advisories help fishers reduce search time for fishing grounds, lower fuel costs, and encourage sustainable fishing. INCOIS thus plays a significant role in improving catch per unit effort and the livelihoods of fisher communities. This study traces the evolution of marine fishery advisory services for the Indian seas and examines the role and impact of PFZ advisories in India's fisheries sector, with particular emphasis on their ecological, economic, and climate-related advantage over the years. For a more robust and sustainable blue economy, the results also highlight the need to combine traditional fishing knowledge with contemporary technological tools.
