Satellites Guide India's Fishermen to Richer Catch

For generations, Indian fishermen relied on instinct to find fish. Now, satellites orbiting overhead provide daily Potential Fishing Zone (PFZ) advisories, a service developed by INCOIS. This transformation has helped nearly 1.4 million fishermen reduce search time, fuel costs, and operating expenses.

These advisories use satellite data on sea temperature and chlorophyll to predict where fish aggregate. Initially infrequent, they are now daily, accessible via mobile apps, radio, and websites in multiple languages. Studies indicate PFZ-guided fishing generates billions in annual benefits, with fishermen reporting substantial income increases per trip.

PFZ advisories significantly cut search times, enabling shorter, more profitable fishing trips. Field validations consistently show higher catches within PFZs compared to outside areas. This efficiency extends to environmental benefits, including reduced fuel consumption and carbon emissions.

The system incorporates ecological safeguards, suspending advisories during fishing bans and avoiding sensitive marine areas. Innovative species-specific forecasts, like the Yellowfin Tuna and Hilsa Fishery Advisories, use advanced data and machine learning for targeted fishing while protecting breeding grounds.

Technology further enhances accessibility through devices like GEMINI and apps such as SAMUDRA and FISH, which provide real-time ocean data and allow fishermen to share observations. This participatory approach merges traditional knowledge with modern science, although scientists emphasize the need for further study on ecological impacts and balancing efficiency with conservation.
