The Indian oil sardine

The Indian oil sardine, Sardinella longiceps Val. sustains one of the major pelagic fisheries of the country.Though the fish occurs all along the peninsular region in varying quantities, the highest abundance has been noticed off the Kerala and Karnataka coasts, especially between Alleppey and Karwar. During the decade from 1969 to 1978, the highest all India oil sardine catch, was made in 1970. From the existing catch trends it is indicated that the sardine catches during the 1980 season would not be far from the average of the last decade. In the light of the stock assessment studies it may be mentioned that increase in fishing effort would result in better catches

Technoeconomic assessment of marine fish production, marketing and capacity utilization of processing plants in Gujarat

Among the major maritime states of India, Gujarat has the longest coastline (1,600 km) and the largest continental shelf area (1,65,00 sq.km). The current annual catch of marine fish in this state is 6,45,261 tonnes (1994-'95). landed in about 221 coastal fish landing centres by 21,018 fishing units, manned by about 0.75 lakh fishermen

Studies on the threadfin bream and the lizard fish resources in the Exclusive Economic Zone of India based on the demersal trawling operations of FORV Sagar Sampada

The present paper deals with the distribution and abundance of the threadfin bream and the lizardfish resources available for exploitation in the Exclusive Economic Zone of India based on the demersal trawling operations of FORV Sagar Sampada during her cruises 1-5

Socio economic study of two brackish water sites in the state of Kerala

Fisheries form arl important seg ment of the Indian economy in terms of income generation and employment contributed Rs 5082 crores at factor cost to India's Gross Domestic Product (GDP) in 1992-93 . It also supports the livelihood of about 10 million people. The export earnings from fisheries in 1994-95 is Rs 3270 crores through the sales of lakh tonnes of sea food accounting for 3.2 percen t of the total export earnings. Prawn occupies major share in terms of quantity and value and is the potential variety for boosting our exports. With the declining prawn catch from capture fisheries, attention has been diverted to aquaculture

Economic evaluation of composite culture practices of crab fattening and fish-shrimp farming in Kerala

The aquaculture industry in India is picking up rapidly in view of its high income and employment generating potential. Recently there has been a drastic reduction in the production of shrimps from our aquaculture fanns due to the outbreak of disease. The declining demand for shrimps in export market further induced our fanners to look for alternative lucrative farming practice

Distribution and abundance of the genus Vinciguerria (Gonostomatidae) in the DSL of Indian EEZ with a note on the biology of Vinciguerria nimbaria

In the DSL fish biomass one of the dominant genus was Vinciguerria, represented by three species such as V. nimbaria, V. attenuata and V. poweriae. The occurrence of Vinciguerria was frequent in nortliwest and southwest area of EEZ at varying depths. The average number per haul in Isaac Kidd mid water trawl (IKMT) was 149 in day and 191 in night collection. Vinciguerria nimbaria has accounted for more than 95% of the total catch of the genus. Its total length varied from 10-56 mm. The length weight relationship is log W = -5.5691 + 3.1676 log I. Invariably the species fed on copepods, ostracods, cladocerans, appendicularians euphausiids, chaetognaths, fish larvae etc. with variations in feeding intensity during day and night. About 92 % of the catch belonged to mature fishes. The species spawns only once in a year and the fecundity ranged from 140 to 770 ova in fishes of 34 - 55 mm total length

Distribution, abundance and biology of unicorn cod, Bregmaceros mcclellandi in the deep scattering layers of Indian Exclusive Economic Zone

In the deep scattering layer (DSL) the fishes have accounted for 5.4 % of the total (numerical) biomass. Juvenile fish belonging to different families were the most abundant component followed by Vinciguerria, myctophids, leptocephali, stomiforms, and unicorn cod. The "unicorn cod is represented by a single species, Bregmaceros mcclellandi (2.4%) in the total fish biomass. It occurred in 52 stations out of 445 IKMT stations. During day time the average number per haul was 21 where as in night hauls it was 29. The resource was fairly abundant along the northwest coast within the depth belt of 200 m. Biological studies on the size composition, feeding habits, and reproductive biology of the species were also carried out. The length ranged from 10-65 mm. The major diet consists of copepods, euphausiids, cheatognaths, ostracods and decapod larvae. Invariably the feeding intensity was low. The catch was composed of mostly females in maturity stages IV-V. The species spawns only once in a year. The fecundity ranged from 530 - 980 in fishes of 42 - 50 mm in total length
