dc.description.abstractThe EEZ of India includes four seas viz: Arabian Sea, Lakshadweep Sea, Bay of Bengal and Andaman & Nicobar Sea. All the seas except the Andaman and Nicobar Sea are extensively surveyed. The total number of cruises undertaken in the EEZ are 178. More than 50% of the coverage was done by RV Gaveshani (1976-86) and 75% area is covered under the National Oceanographic Programmes. In general, monthly coverage shows a maximum during March and June and seasonally the maximum is during the pre-monsoon period. Latitudinally study shows maximum coverage between 14-15 degrees N and longitudinally maximum coverage is in between 73-74 degrees E of the EEZ boundaries. Oceanographic stations and Geophysical survey coverage are greatest on the west coast. More gaps exist in the Andaman Nicobar Sea followed by Lakshadeep and the Bay of Bengal. The oceanographic characteristics show that the surface coastal water of the Bay of Bengal is little warmer than the Arabian Sea, the range being 22.5 degrees C to 30.5 degrees C. At 200 m it varies from 13 degrees C to 17 degrees C. Salinity decreased from north to south in the Arabian Sea whereas it was vice-versa in the Bay of Bengal and Andaman & Nicobar Sea. In surface waters of the EEZ, the maximum (6.1 ml/1) and minimum (3.8 ml/1) values of oxygen concentration were noticed in the EEZ portion of the Arabian Sea. Low values of nutrients are observed in the surface waters of the northern Arabian Sea and the northern part of Bay of Bengal. The surface primary production varied from 0.3 to 86.7 mgc/mu3/day. The surface production per unit area is marginally higher along the west coast waters than in the east coast waters whereas column production is much higher in the waters of the eastern coast than the western coast. From the primary, secondary and benthic production the total fish potential has been estimated to be 4.25 million tonnes per year
