Solar desalination, brine and fine chemicals - a preliminary report
(Indian Association for Limnology and Oceanography, 1991)Solar stills put into operation by taking known quantities of sea water of different salinities varying from 27.75-36.27 x 10 super(3) during April-May 1990, indicated fresh water yield of 55-68% (av. 64). The volumes of ... -
Bioactivity and chemical ecology of some intertidal animals
(Oxford and IBH, New Delhi, 1991)Some marine organisms from intertidal regions of the Indian Coast have shown promising activities. Marine sponges, coelenterates, molluscs, and echinoderms are found to possess rich sources of novel chemical compounds. The ... -
Bioactivity of marine organisms. Part 3. Screening of marine algae of Indian coast for biological activity
(Indian Association for Limnology and Oceanography, 1991)Ethanolic extracts from Indian marine algae have been tested for anti-viral, anti-bacterial, anti-fungal, anti-fertility, hypoglycaemic and a wide range of pharmacological activities. Of 34 species investigated 17 appeared ... -
Copepods of the nearshore waters of Bombay
(NISCAIR, New Delhi, 1991)Variability in copepod population was studied along 2 transects off Mahim and Versova (Bombay, Maharashtra, India) during November 1979 to December 1980 covering eight stations from the creek towards the offshore area. ... -
Occurrence of thraustochytrid fungi in corals and coral mucus
(NISCAIR, New Delhi, 1991)Occurrence of thraustochytrid fungi in corals, fresh coral mucus and floating and attached mucus detritus from the Lakshadweep Islands in the Arabian Sea was studied. Corallochytrium limacisporum Raghukumar, Thraustochytrium ... -

The killer tides
(NISCAIR, New Delhi, 1991)Toxic red tide is a disastrous phenomenon causEd. by sudden blooming of certain killer microorganisms often encountered in the seas. Certain killer red tides have caused wide-spread losses to human life and to the fishing ... -
Assessment of cyst production potential of a natural population of brine shrimp Artemia
(NISCAIR, New Delhi, 1991)Studies on a natural population of Artemia in the salterns of Jamnagar indicated that the population is parthenogenetic. These shrimps reach a maximum size of 9 mm. Number of cysts per brood varies from 10-32. Adults form ... -
Phytoplankton assemblages and pigments in the exclusive economic zone of Mauritius (Indian Ocean)
(NISCAIR, New Delhi, 1991)Nutrient enrichment studies showed that both inorganic salts of nitrogen and phosphorus were limiting for phytoplankton from the surface waters. This coupled with conditions of high insolation prevailing at this time ... -
A multivariate statistical study with a factor analysis of recent planktonic foraminiferal distribution in the Coromandel Coast of India
(Indian Fisheries Association, 1991)A study of planktonic foraminiferal assemblages from 19 stations in the neritic and oceanic regions off the Coromandel Coast, Bay of Bengal has been made using a multivariate statistical method termed as factor analysis. ... -
Fungi and their biomass in detritus of the seagrass Thalassia hemprichii (Ehrenberg) Ascherson
(Walter de Gruyter, Berlin, 1991)Four different stages of detritus from the seagrass Thalassia hemprichii Ascherson from two coral islands in the Lakshadweep Archipelago, Arabian Sea were examined for the presence of fungi. Direct microscopic examination ... -

Two simple amine hydrochlorides from the soft coral Lobophytum strictum
(NISCAIR, New Delhi, 1991)Two simple amine hydrochlorides, viz., 1-amino-1, 1-dimethyl-3-oxo-butane hydrochloride (1) (Diacetonamine) and 2, 2, 6, 6-tetramethylpiperidone hydrochloride (2) have been isolated from the fraction of the methanolic ... -
Energy content of suspended detritus from Arabian Sea
(NISCAIR, New Delhi, 1991)Energy components of suspended matter included phytoplankton, zooplankton and detritus inclusive of microorganisms adsorbed to detritus. Of these, detritus contributed most of the energy (98%). The average caloric content ... -

Zooplankton and fisheries
(NIO, Goa, 1991)Zooplankton are considered as the chief index of utilization of aquatic biotope at the secondary trophic level. The intensity of zooplankton aggregation depends on their ability to counter dispersion, phytoplankton growth, ... -
Interdependence of environmental parameters and sand dwelling benthic species abundance: a multivariate approach
(NISCAIR, New Delhi, 1991)Multivariate analysis showed dependence of distribution and abundance of sand dwelling fauna on more than one ecologically significant environmental parameters rather than one ecological master factor. Salinity, grain size, ... -
