      • Benthos of the Shelf Region along the West Coast of India 

        Harkantra, S.N.; Nair, A.; Ansari, Z.A.; Parulekar, A.H. (CSIR-NISCAIR, 1980)
        Distribution and abundance of benthos in the depth range of 10-70 m were studied. A definite relationship was observed between benthic biomass, organic carbon, nature of substrata and demersal fish catch. Benthic biomass ...
      • Dissolved Petroleum Hydrocarbon Concentrations in some regions of the Northern Indian Ocean 

        SenGupta, R.; Qasim, S.Z.; Fondekar, S.P.; Topgi, R.S. (Elsevier, 1980)
        Dissolved petroleum hydrocarbons were measured in some parts of the Northern Indian Ocean using UV bsorbance technique with a clean up step. The concentration of oil ranged from 0.6 to 26.5 mu gl. Higher values were ...
      • Distribution of Petroleum Hydrocarbons in Goa Coastal Waters 

        Fondekar, S.P.; Topgi, R.S.; Noronha, R.J. (CSIR-NISCAIR, 1980)
        Average hydrocarbon concentrations in water, plankton and sediment samples collected from the central west coast of India between 14 degrees 40'N and 15 degrees 50'N were 30.9 mu g/litre, 46.9 mu g/g dry wt and 7.1 degrees ...
      • Physical features of Nearshore Waters off Karwar 

        Gopinathan, C.K.; Joseph, P.S. (CSIR-NISCAIR, 1980)
        Very little change in the hydrographic properties with depth during October 1975 to October 1976 was observed except during August-October, when waters of low temperature ( 24 degrees C), high salinity ( 35.5 ppt) and low ...
      • The Protozoan Associates of some Crustaceans 

        Santhakumari, V.; Gopalan, U.K. (Indian Association for Limnology and Oceanography, 1980)
        Protozoan associates found on the estuarine shrimp Metapenaeus monoceros (Fabricius) and the tanaidacean Apseudes chilkensis (Chilton) from Cochin backwaters have been described. A peritrich ciliate Zoothamnium rigidum ...
      • Planktonic Ostracods of the Northern Indian Ocean 

        George, J.; Nair, V.R. (Indian Association for Limnology and Oceanography, 1980)
        Thirty-two species of ostracods were identified from 712 samples collected from northern Indian Ocean. Two of them belong to Cypridinidae and the rest to Halocyprididae. Most of the species are common to those of the ...
      • Isolation and Significance of Salmonella sp. from some Beaches of Kerala 

        Gore, P.S.; Iyer, T.S.G.; Raveendran, O.; Unnithan, R.V. (Indian Association for Limnology and Oceanography, 1980)
        Salmonella sp. obtained from the sand samples of some beaches of Kerala during July-October 1978 have been reported. Its percentage occurrence was 22.7. However, water samples failed to give positive Salmonella isolations ...
      • Fungal infection in the tiger prawn (Penaeus monodon) and in other crustaceans from the Cochin Backwaters 

        Gopalan, U.K.; Meenakshikunjamma, P.P.; Purushan, K.S. (Indian Association for Limnology and Oceanography, 1980)
        Infection of the two species of fungi (Phycomycetes) in the tiger prawn (Penaeus monodon) and three species in amphipods (Gammarus sp.) and tanaeidaceans (Apseudes sp.) was observed. Of the two pathogens in the shrimp, ...
      • Biochemical Constituents of Seaweeds along the Maharashtra Coast 

        Dhargalkar, V.K.; Jagtap, T.G.; Untawale, A.G. (CSIR-NISCAIR, 1980)
        Protein, carbohydrate and organic carbon were estimated in 43 marine algal species from different stations along the Maharashtra Coast in India These species showed variation in their biochemical contents Protein varied ...
      • A Closed Loop Electromagnetic Flowmeter 

        Desa, E.S.; Desa, E. (IOP Publishing, 1980)
      • Effect of Petroleum Products on Mangrove Seedlings 

        Jagtap, T.G.; Untawale, A.G. (Indian Association for Limnology and Oceanography, 1980)
        The effect of petrol, diesel and motor oil was studied on the fruits of Rhizophora mucronata and Avicennia officinalis. The former species was found to be more resistant to these petroleum products than the latter, in which ...
      • Sensor Design for an Electromagnetic Flow-Meter 

        Desa, E.S.; Desa, E. (CSIR-NISCAIR, 1980)
      • Zooplankton Biomass and Composition in the Western Bay of Bengal during late SW Monsoon 

        Achuthankutty, C.T.; Madhupratap, M.; Nair, V.R.; Nair, S.R.S.; Rao, T.S.S. (CSIR-NISCAIR, 1980)
        Copepoda formed the predominant group except in the southern region where a swarm of pelagic tunicates reduced their contribution to only 19% of the total zooplankton count. Decapod larvae occurred in fairly large numbers ...
      • Swarming of Pelagic Tunicates Associated with Phytoplankton Bloom in the Bay of Bengal 

        Madhupratap, M.; Devassy, V.P.; Nair, S.R.S.; Rao, T.S.S. (CSIR-NISCAIR, 1980)
        During the 40th cruise of R V Gaveshani, a large swarm pelagic tunicates associated with a bloom of diatoms and blue green algae was observed off Nagapattinam. The doliolid Dolioletta gegenbauri, Uljanin, the salp Thalia ...
      • Relationship between Benthic Foraminifera and Sediment in the Estuarine Complex of Goa 

        Dalal, S.G. (Indian Association for Limnology and Oceanography, 1980)
