Trends in the yields of major exploited fisheries of The east coast of India

On the east coast of India, the elasmobrancbs, cat fishes, 'other sardines', anchovies and white baits, 'other clupeids', sciaenids, ribbon fish, silverbelHes and penr.cid prawns form the major fisher'es and contribute about 63% of the total mar'ne fish catch of the coast. The trends in the yields of these fisheries of this coast during the 21-year period from 1932 to 1972 have been analysed. A study of th'i fluctuations in the trends in the yields assumes greater importance as no up-to-date information is available at present about the nature of trends of major exploited fisher'es of the east coast of India especially in view of the diversification of fishing on this coast. The study reveals that in West Bengal and Orissa, elasmobrancbs, cat fishes, anchovies and white baits, other clupeids. sciaenids, ribbon fish and silverbeHies form a good fishery and it is predcted that ^ese fisheries will continue to yield good catches in future also. In Andhra the fisheries ctf other sardines, other clupeids, sciaenids, ribbon fish and penaeid prawns are successful and they w'll maintain the present increasing trend in their landings in the coming years also. In Tamil Nadu, it is seen that only cat fishes, other sardines, anchovies and white baits and sciaenids form very good fishery and they will yield higher catches also in the future years

Appraisal on the marine fishing craft and gear of the Indian coast

The use of fishing methods varying from simple traps to large trawlers and from hand lines to sophisticated purse seines is a typical feature of marine fisheries in India. The regional and seasonal variation is so vast that the developmental agencies and administrative machinery are often handicapped in deciding priorities on modernizing the traditional tools. A document as attempted here, would form a piece of vital information for the R&D agencies. The traditional gear operated in different regions of the Indian coast are classified based on the mode of operation and an exhaustive listing along with local names is attempted. Besides, contributions to the marine fish production separately by traditional and modern craft are brie flu noted

Appraisal of the Marine Fisheries of West Bengal

The state of West Bengal is situated between the latitudes 21.5CN and 24.5°N and the longitudes 86CE and 89°E. Its location is in the northern part of Bay of Bengal; between the state of Orissa in the south and Bangladesh in the east. West Bengal, with an area of 87,853 sq. km accounts for 2.6% of the geographical area of India.

The resources of hilsa shad, Hilsa ilisha (Hamilton), along the northeast coast of India

The results of 4study on the fishery, biology, exploitation and mortality of hilsa shad (Hi1.w ilishu) are presented. The average annual landing of Hilsa ilisha for 1979 -88 was 57 10 tomes forming 0.4% of the total landings. The major craft and gears and [he contributions of different states arepresented.
