Primary production of tropical marine ecosystems
(Wiley Eastern, New Delhi, 1992)Among tropical marine ecosystems estuaries are one of the highly productive areas and act as a nursery to large number of organisms. The primary production in most of the estuaries is less during the monsoon period. ... -
Diseases of chaetognaths from the Arabian Sea
(Marine Biological Association of India, 1992)Three different diseases, provisionally assigned as spot disease, swell disease and tail rot disease, were observed in chaetognaths Sagitta enflata Grassi and S. bedoti Bernaneck. The first two diseases showed high percentage ... -
Nitrate and sulfate reducers-retrievable number of bacteria and their activities in Indian waters
(Oxford and IBH, New Delhi, 1992)Culturable heterotrophic, nitrate reducing and sulfate reducing bacteria (HB, NRB and SRB) were enumerated from 25, 50, 100 and 200 m depths at 15 stations and their potential activities viz. Nitrate reducing (NRA) and ... -
Marine flora of Nicobar group of islands in Anadman Sea
(NISCAIR, New Delhi, 1992)The marine flora of 4 islands comprised 66 species of marine algae, 7 of seagrasses, and 10 of mangroves. Maximum number of marine algae (6) and mangroves (9) were reported from Great Nicobar Island, whereas more (7) species ... -
Role of mangroves in brackish water fish culture
(1992)Mangroves is a specialized marine ecosystem consisting of a group of plants growing in muddy, loose and wet soils in tropical and subtropical areas, comprising of shallow, coastal waters, deltas, estuaries or lagoons. ... -
Seasonal variations in the volume of the haemolymph and body weight of the horseshoe crab, Tachypleus gigas (Muller)
(Pakistan Council of Scientific and Industrial Research, 1992)The changes in volume of haemolymph of the horseshoe crab, Tachypleus gigas were more pronounced in females of size above 160 mm with maximum values in size group 241-260 mm. In males, the variations in the volume of ... -
Studies on antagonistic marine streptomycetes
(Oxford and IBH, New Delhi, 1992)Sixty nine strains of Streptomyces sp. isolated from the sediments of Andaman and Nicobar islands (Bay of Bengal) were screened for their antagonistic property against a number of test cultures (Vibrio sp., Klebsiella sp., ... -
Culture fishery resources of the tropical marine ecosystems
(Wiley Eastern, New Delhi, 1992)The exploited marine living resources, through capture fisheries, have their own limitations of resource potential, marine pollution and ever increasing operational cost. A plausible way to fulfil the increasing demand of ... -
Biofoulers on aluminium and stainless steel panels at Vijaydurg harbour, central west coast of India
(NISCAIR, New Delhi, 1992)Occurrence of cirripede larvae in the water column and their settlement on the panels throughout the year showed that barnacles were the prolonged breeders. Fluctuations in the salinity values appear to have affected the ... -
Zooplankton studies in the south west coast of India
(Kerala Science Congress, 1992) -
Zooplankton of the southwest coast of India: abundance, composition, temporal and spatial variability in 1987
(Oxford and IBH, New Delhi, 1992)During early southwest and northeast monsoon periods of 1967, zooplankton standing stocks and abundances were high all along the west coast of India. Swarms of zooplankton were common in the shelf areas resulting in a low ... -
Massarina armatispora sp. nov., a new intertidal ascomycete from mangroves
(Walter de Gruyter, Berlin, 1992)Massarina armatispora sp. nov. is described from dead intertidal mangrove wood collected in India and Hong Kong. The new taxon is compared with other M. species, and its placement in the genus Massarina is discussed -
Primary productivity of the Arabian Sea
(Wiley Eastern, New Delhi, 1992)Reversal of surface circulation during the monsoons, patchy nutrient distributions and high light intensity drive phytoplankton production processes in the tropical Arabian Sea. Available data are discussed in the light ... -
Biochemical composition and caloric potential of zooplankton from Bay of Bengal
(NISCAIR, New Delhi, 1992)Proximate composition and variations in protein, lipid, carbohydrate, ash and organic carbon in zooplankton from 42 stations in the Bay of Bengal are reported. Average percentages of moisture, protein, lipid, carbohydrate, ... -
Observations on seabirds in the Indian Sector of the Southern Ocean

Moulting and moult quality in eye-stalk ablated penaeid prawn, Metapenaeus monoceros (Fabricius)
(Kerala Science Congress, 1992) -
Ecology and biology of luminous bacteria in the Arabian Sea
(Oxford and IBH, New Delhi, 1992)Extensive studies on occurrence, distribution and species composition of luminous bacteria in the Arabian Sea were carried out from various habitats. Luminous bacterial population was by far the highest in the environs of ... -
Microdistribution of zooplankton in the neustonic realm of the eastern Arabian Sea during southwest monsoon
(Oxford and IBH, New Delhi, 1992)During the southwest monsoon season of 1987, the zooplankton distributions in the neustonic realm (upper 50 cm) of the eastern Arabian Sea were studied and compared with those in the water column. The upper microlayer ... -
Production of L-Asparaginase by the marine luminous bacteria
(NISCAIR, New Delhi, 1992)Fortythree strains of luminous bacteria, belonging to 4 species, (Vibrio harveyi, V. fischeri, Photobacterium leiognathi and P. phosphoreum) isolated from different marine samples, were examined for the production of ... -
Benthic fauna around Mauritius island, southwest Indian Ocean
(NISCAIR, New Delhi, 1992)Distribution of benthic fauna in the Exclusive Economic Zone of Mauritius was studied during September-October 1987. Mean faunal density (macro+meio) and dry weight biomass was 10848 no.m/2 and 228.8 mg.m/2, respectively. ...
