Prospects of Artemia culture in the coastal zone
(Omega Scientific, New Delhi, India, 1996)The importance of the brine shrimp Artemia as live feed in shrimp hatcheries has been pointed out. The paper deals with the resource potential and status of cyst production in India. There is a need for setting up a Pilot ... -
Biological investigations of Indian phaeophyceae 16. Antibacterial acitivity of phenolic substances, extracted from Sargassum johnstonii Setchell et Gardner collected from Okha, west coast of India
(Seaweed Research and Utilization Association, 1996)Free and hydrolysed phenolic substances were extracted from a dry sample of Sargassum johnstonii using 80% methanol and tested for their antibacterial activity by agar diffusion method. The growth of two gram-positive ... -
Phytoplankton production and chlorophyll distribution in the eastarn and central Arabian Sea in 1994-1995
(Current Science Association, Bangalore, India, 1996)Measurements of primary production, chlorophyll a, particulate organic carbon (POC) and nitrogen (PON) were carried out during the inter-monsoon winter monsoon and summer monsoon seasons of 1994-95 in the central and eastern ... -
Morphology, taxonomy and ecology of Thraustochytrids and Labyrinthulids, the marine counterparts of zoosporic fungi
(M D Publications, New Delhi, India, 1996)The most common zoosporic fungi, or to use a compromising, term which seems right according to the current perspective, the fungi-like protists, in the marine environment are the thraustochytrids and labyrinthulids. According ... -
Zooplankton standing stock, community structure and diversity in the northern Arabian Sea
(Department of Ocean Development, New Delhi, India, 1996)The effects of large scale oil spill, which occurred during the Gulf War in 1991 on zooplankton standing stock, community structure and diversity in the northern Arabian Sea were studied. Surface (1-0 m) and vertical ... -
Occurrence and distribution of soft corals (Octocorallia: Alcyonacea) from the Andaman and Nicobar Islands
(Bombay Natural History Society, 1996)Occurrence and new distributional records for 26 species of Alcyonaceans are given. These include 12 species of Sinularia, 6 of Lobophytum, 6 of Sarcophytum, one of Cladiella and one of Nephthea. Their ecological information ... -
Ammonium sulphate induced stress related alterations in the respiratory epithelium of the airbreathing organ of the catfish Heteropneustes fossilis (Bloch)
(Indian Academy of Sciences, Bangalore, India, 1996)In this paper, histopathological changes in the inner lining of the accessory respiratory organ of Heteropneustes fossilis following exposure to sublethal concentration (0.2 gl sup(-1)) of ammonium sulphate (3 mg l sup(-1) ... -
Ecobiological studies of the freshwater lakes at Schirmacher Oasis, Antarctica
(Department of Ocean Development, India, 1996)Ecological studies of the freshwater lakes at the Schirmacher Oasis have been reported. Physical variables such as atmospheric temperature, solar radiation, winds, etc. showed that the environment at Schirmacher Oasis is ... -

Annual and seasonal mean buoyancy fluxes for the tropical Indian Ocean
(Current Science Association, Bangalore, 1997)INSAT-derived monthly mean precipitation, combined with estimates of evaporation from COADS, are used to prepare the annual mean and seasonal distributions of evaporation-precipitation (E-P)) and buoyancy fluxes for the ... -
A semi-diagnostic calculation of climatic circulation in the western Indian Ocean
(NISCAIR, CSIR, 1997)A 3-dimensional, semi-diagnostic circulation model is used to compute the climatic circulation in the upper levels of western tropical Indian Ocean (20 degrees S-30 degrees N and 35 degrees E-80 degrees E) during the ... -
Annual and interannual variation of precipitation over the tropical Indian Ocean
(American Geophysical Union, 1997)The annual and interannual variability of precipitation over the tropical Indian Ocean is studied for the period June 1986 to December 1990 using the data retrieved from the Indian National Satellite (INSAT). The seasonal ... -
Sensitivity experiments with an adaptation model of circulation of western tropical Indian Ocean
(NISCAIR, CSIR, 1997)One 18-level adaptation model of circulation with a flat bottom at 900 m depth has been used to study the sensitivity of the solution to different magnitudes of eddy viscosity and diffusivity coefficients. Three numerical ... -
Computation of large scale currents in the Arabian Sea during winter using a semi-diagnostic model
(Indian National Science Academy, 1997)A 3-dimensional, semi-diagnostic model with 331 levels in the vertical has been used for the computation of climatic circulation in the western tropical Indian Ocean. Model is driven with the seasonal mean data on wind ... -
Predicting monsoon rainfall and pressure indices from sea surface temperature
(Current Science Association, Bangalore, 1997)The relationship between the sea surface temperature (SST) in the Indian Ocean and monsoon rainfall has been examined by using 21 years data set (1967-87) of MOHSST.6 (Met. Office Historical Sea Surface Temperature data ... -
Storm surge in the Bay of Bengal and Arabian Sea: The problem and its prediction
