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
Catch trend of commercial trawl fisheries at Krishnapatnam Port. Nellore district, Andhra Pradesh
Of the five fisheries harbours in the Andhra
Pradesh, Visakhapatnam Fisheries Harbour has
been classified as major and the harbours at
Kakinada (East Godavari district), Bhavanapadu
{Srlkakulam district), Nizampatnam (Guntur
district) and Krishnapatnam Port (Nellore district)
as minor harbours
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. For administrative purposes, the state is
divided into 3 Divisions : Burdwam Division, Presidency Division and
Jalpaiguri Division. Within each division the districts form administrative
units. There are 16 districts of which two are coastal. The coastal districts
are Midnapore and 24 Parganas. These together have a coastline of 65.0 km,
forming 1.0% of the coastline of India
Appraisal of the Marine Fisheries in Orissa
The State Orissa is situated between latitudes 17.75┬░N and 22.5┬░N
and longitudes 81.5┬░E and 87.6┬░E, bordered by the Bay of Bengal in the
east, West Bengal in the north-east, Bihar in the north, Madhyapradesh in
the west and north-west, and Andhra Pradesh in the south.
Orissa, with an area of 1 55,842 sq. km. accounts for 4.7% of the
geographical area of India. The state has 13 districts, of which four are
coastal. The coastal districts are Balasore, Cuttack, Puri and Ganjam. These
together have a coastline of 480 km. forming 8% of the coastline of India
