Both the statements are individually true and Statement II is the correct explanation of Statement I. Indian marine fish harvest mostly centres around coastal waters up to 100 metres depth and about 90 per cent of the catch comes from up to 50 m. In other words, India is presently harvesting about 12% of the potential and the balance can be optimally harvested using a judicious mix of technology, infrastructure and human resource development. The straight and regular coastline of India is the result of faultingof the Gondwanaland during the Cretaceous period. As such, thecoast of India does not offer many sites for gulfs, bays, estuaries and backwaters which are good fishing grounds.
