Abstract

India possesses extensive marine fisheries resources, including an 8,118 km long coastline, a territorial sea spanning 193,834 km² (extending 12 nautical miles or 22.2 km from the shoreline), and a marine fisher population of approximately 4.0 million residing in 3,432 marine fishing villages across 66 coastal districts in 9 maritime states and 2 Union Territories, in addition to the Island Territories of Andaman & Nicobar and Lakshadweep. The infrastructure available consists of 6 major fishing harbours, 40 minor fishing harbours, and 1,537 marine fish landing centres. The relatively shallow inshore waters along the extensive coastline of the mainland and island territories provide potential for sea cage farming, particularly in sheltered areas such as bays, lagoons, and semi-exposed and exposed coasts with minimal wave action. The existing marine infrastructure and fisher population serve as complementary resources.
