Marine Fishing in Japan The meeting of warm Kuroshio and cold Oyashio current provides plankton, which is ideal for fish. Big corporations with modernized ships and equipment, help the people to go in the open ocean. There are many gulfs, bays, estuaries with a large number of ports providing a larger coastline helping in better opportunities in marine fishing in Japan. Marine Fishing in India There is no cold and warm ocean current confluence along the Indian coast. So plankton is not available. Most of the fishermen use non-mechanized boats. They normally do not go beyond 10 km. The Indian coasts do not have many gulfs, bays, estuaries, and backwaters and also not many ports leading to a lesser coast-line and thereby reducing the opportunities in marine fishing in India.
