The estimated landings of carangids in India during 198 1-88 ranged between 37 345 tonnes and 135 529
tonnes, whereas the percentage composition of carangids in the total fish Wigs ranged from 2.7 to 8.1. The
overage annual catch and the percentage of carangids in the total marine fish landings were estimated at 74 080
tonnes and 4.5% respectively. Tamil Nadu (17.7%) and Andhra Mesh (8.8%) from east coast and Kerala
(34%). KamPtakn (17.6%) and Maharashtra (9.9%) from west coast yielded good catches of carangids.

The Bombay duck, Harpadon nehereus (Hamilton,
1822) form a major single species fishery along the
Northwest coast from Ratnagiri in Maharashtra to the
Gulf of Kutch in Saurashtra coast. They also form a
seasonal fishery along Northeast coast (West Bengal &
Odisha) and the northern part of Andhra Pradesh. The
fishery is usually concentrated in a comparatively narrow
depth zone up to 70 m and are mainly exploited by
stationary bag net known as 'Dol' which are operated
entirely by tidal force

Puducherry Union Territory has 45 km of coast
which extends from Kanagachettykulam in the north
to Murthykuppam in the south and contributes around
5% to the total marine fish catch of the country. The
average annual catch was 15,492 t during 2005 –
2009. One of the most significant development in
the marine fisheries sector observed in recent years
is the large scale introduction of ringseine boats for
commercial exploitation of pelagic fish resources,
which is also observed along the coast off
Puducherry.

Tamil Nadu with a long coastline of 1,076
km ranks second among all the maritime states in
India in terms of coastal length and fourth in terms
of marine fish production in India. The continental
shelf of Tamil Nadu has been estimated to be about
41,400 sq km. The estimated annual marine fish
production in Tamil Nadu during 1995-2005 has
fluctuated from 3,50,709 t (2001) to 4,72,513 t (1997)
with an average annual landing of 3,90,797 t. The
annual marine fish landings of Tamil Nadu has been
recorded to range from 13.7 to 19.0% constituting
on an average 16% of the total marine fish production
in India (Srinath et al., 2006).

India is blessed with long coastline of about 8118 km along the West Bengal, Odisha, Andhra
Pradesh, Tamil Nadu and Pondicherry along the east coast; along Gujarat, Maharashtra, Goa,
Karnataka, Kerala along the west coast. India has 2.02 million sq.km exclusive economic zone
area and 0.53 million sq.km continental shelf area, a potential source for marine fisheries.The
rich continental shelf area, a good habitat for demmersal fishes as well as crustaceans such
has penaeid prawns , non-penaeid prawns, crabs, lobsters and stomatopods. Mechanised
trawler is the main gear operated in the continental area targeting crustacean resources,
Though trawl net is operated for penaeid prawn, non penaeid prawns, crabs and stomatopods
will be formed as by catch because all these resources habituate in the same fishing ground.

Landings of the white sardine Escualosa thoracata (Valenciennes, 1847) indicated a shift in their abundance from northeast to south-west coast of India and a sharp decline in the resource landings during the last decade along the entire range of its distribution. High local demand coupled with competitive price for the species might have led to overexploitation of this otherwise seasonal resources along the major areas of its abundance along the Indian coast. Detailed study on the systematics, fishery and biology of the species landed along Kerala coast was undertaken during 2015 and 2016. Stock assessment studies indicated near optimum fishing pressure on the resource along the Kerala coast.

A single specimen of Xanthichthys lineopunctatus (187 mm SL and
weight 212 gm) was obtained from trawl net operated at depth range
of 40-50 m off Visakhapatnam and landed at Visakhapatnam Fisheries
Harbour on 20th July 2016. It is reported for the first time from the east
coast of India, Bay of Bengal. Earlier it was recorded from the south west
coast of India, Arabian Sea and from the Indo-West Pacific. This report
of Xanthichthys lineopunctatus in the Bay of Bengal extends its
geographic distribution within the Indian Ocean.

Tuna production in the' world continued to increase from an average annual catch of 1.745 million t during 1970-'74 to a
peak of 5.975 million t in 1999. The Pacific Ocean produced 68.9% followed by the Indian Ocean 17.3% and the Atlantic
Ocean 13.8%. Skipjack was the most dominant species constituting 35.3% followed by yellowfin 25.9%. big-eye 6.3%.
albacore 5%. other tunas 25.3% and longtail, kawakawa, southern and northern bluefins each less than 1%. Except
skipjack. and albacore in the Atlantic, northern bluefin in the western Atlantic, kawakawa, longtail and other small tunas
in the eastern Indian Ocean, all other species are fully exploited and some of them are at the verge of depletion. Tuna
production from India continued to increase from a mere 3445 t in 1969 to a peak of 46,466 t in 1997. The species
composition was E. afJinis 52.3%. Auxis spp. 21.2%. K. palamis 2.0%, T. ronggol8.6% and other tunas 15.9%. The west
coast landed 85.2% and the east coast 14.8%. The south-west coast contributed 55.4%. north-west coast 29.8%. South- east coast 14.4% and North-east coast a mere 0.4%. The motorised sector landed 50.4% followed by the mechanised
sector 37.8% and non-mechanised sector 11.8%. In the mechanised sector, the gillnet landed 59.4% followed by purse
seine 23.1%, ring seine 10.4% and trawl 7.1%. Other than the coastal tuna fishery, there is no organised fishery for
oceanic tunas in India. Deployment of longline and purse seine fishing fleet for the exploitation of oceanic surface and
sub-surface tunas in the Indian Ocean is discussed and detailed suggestions for the development and management of the
oceanic tuna tishery are given.

IN the marine fisheries of the Indian coast prawns occupy an important position. The major portion of the marine prawn catches is from the west coast. According to Panikkar and Menon (1955) certain areas, especially on the west coast, the catches of prawns as a group may be more than those of any other single group of fishes. In order to obtain a clear picture of the fishery along this coast detailed study has been initiated by the Central Marine Fisheries Research Institute at a number of centres, viz., Kandla, Bombay, Mangalore, Kozhikode, Cochin (Ernakulam) and Colachel. From the Ernakulam centre the middle part of Kerala coast has been covered selecting three points, Alleppey, Chellanam and Narakkal, about 22 miles apart. Alleppey situated about 35 miles south of Cochin is one of the heaviest prawn-landing centres. Here in some months of the peak season the catches at one landing centre alone has exceeded 1000 m. tons. The presence of mud banks, locally called chakara is one of the reasons attributed to the magnitude of the prawn fishery here. Chellanam, situated at about 14 miles south and Narakkal 8 miles north of Cochin harbour are also prawn fishing centres.
