Plankton production associated with cold water incursion into the estuarine environment
(Indian Association for Limnology and Oceanography, 1983)Phytoplankton blooms comprising mainly of diatoms and dinoflagellates (approx. 0.55 million cell/l) and intense zooplankton swarms (biomass approx. 5.34 ml/m@u3@@) were observed in the Mandovi and Zuari estuarine environment ... -
Primary production in the Bay of Bengal during August 1977
(Indian Association for Limnology and Oceanography, 1983)Primary production, chlorophyll @ia@@, phaeophytin, phytoplankton and particulate organic carbon (POC) were studied at 14 stations in the Bay of Bengal during August 1977. Column primary production, chlorophyll @ia@@, and ... -
Studies on the behaviour of nutrients in the Mandovi estuary during premonsoon
(Elsevier, 1983)Behaviour of silicate, nitrate and phosphate in the Mandovi Estuary was studied during the premonsoon season. The study shows that silicate is removed from the water column while nitrate showed an internal source. This ... -
Zooplankton incidence in abnormally high sea surface temperature in the Eastern Arabian Sea
(CSIR-NISCAIR, 1983)Zooplankton in an abnormally high sea surface temperature (33.1 to 33.8 degrees C) and alternate bands of slick formation were studied in the Eastern Arabian Sea during 26 and 29 April 1981. The phenomenon which may be due ... -
Production and zooplankton community structure in the lagoon and surrounding sea at Kavaratti atoll (Lakshadweep)
(CSIR-NISCAIR, 1983)Higher values for the environmental parameters were generally obtained for the lagoon stations. Average values of pH, temperature, salinity, dissolved oxygen and phosphate-phosphorus, nitrate-nitrogen, silicate and silicon ... -
Meiofauna of some sandy beaches of Andaman Islands
(CSIR-NISCAIR, 1983)Comparatively high meiofauna numbers were recorded from beaches having fine sand particles than those having coarse to medium sand particles The fauna was dominated mainly by nematodes (53.7%), harpacticoids (13.7%) and ... -
Effect of dispersants on the growth of indigenous bacterial population and biodegradation of crude oil
(CSIR-NISCAIR, 1983)Oil dispersants (5 from Castrol Ltd., Bombay and 2 from British Petroleum, London) were studied individually and in combination with Saudi Arabian crude oil for their effect on the growth of indigenous bacteria and on the ... -
Ionic potential as a controller of seawater composition
(CSIR-NISCAIR, 1983)Attempts have been made to study whether linear relations exist between ionic potentials (IP) and factors determining their fate in seawater. Various elements have been studied according to the geochemical classification. ... -
Seawater circulating system in an aquaculture laboratory
(Indian Association for Limnology and Oceanography, 1983)The note gives an account, for the first time in India, of an Aquaculture Laboratory with open type seawater circulating system developed at the National Institute of Oceanography, Goa, India. Besides describing the details ... -
Coexistence and Succession of Copepod Species in the Mandovi and Zuari Estuaries, Goa
(Indian Association for Limnology and Oceanography, 1983)Observations were made on the copepod species association and succession at six stations in the Mandovi-Zuari estuarine system of Goa, India. A total of 55 species belonging to 25 genera and 18 families were encountered ... -
Lipid content in surface water of Arabian Sea
(CSIR-NISCAIR, 1983)Total lipid values varied from 165 - 293 mu g-1/1. Polar fraction was the major constituent (57 - 85%) of total lipid -
Comparative account on zooplankton in polluted and unpolluted estuaries of Gujarat
(Indian Association for Limnology and Oceanography, 1983)An assessment of the zooplankton biomass and composition in Kolak Par, Damanganga and Auranga estuaries was made. Among these four rivers pollution is severe in the first two, moderate in Damanganga and good water quality ... -
Larval Migration and growth of Marine Prawns in the Estuarine Habitat
(Indian Association for Limnology and Oceanography, 1983)Larval migration and growth of @iMetapenaeus dobsoni, M. monoceros, M. affinis@@ and @iPenaeus merguiensis@@ were studied in the Mandovi Estuary and a nearby mangrove swamps for one year. In general, total number of larvae ... -
Studies on the Hydrography and Plankton of waters off Akarpati near Navapur, west coast of India during February-March
(Indian Association for Limnology and Oceanography, 1983)Studies on selected physico-chemical parameters and plankton were carried out in waters off Akarpati during February-March 1978 In general, nutrient values increased towards offshore However, along the northern transect a ... -
Geomorphology of the Goa Coast
(Indian Academy of Sciences, Bangalore, 1982)This paper is based on the observations and interpretations of aerial photographs (1;25, 000 and 1:15, 000) of the Goa Coast. Aerial photocharacters like zonal differences, texture, shape, size, form, pattern, vegetation, ... -
Observations on marine biofouling on electroplated metallic surfaces in Goa waters
(Indian Association for Limnology and Oceanography, 1982)The panels of metallic brass electroplated with cadmium as well as nickel-chromium were kept suspended in the near-shore marine environment of Goa, India for biofouling studies. The results for the premonsoon period, which ... -
Effects of different feeding levels on moulting, growth, food conversion efficiency and biochemical composition of the prawn, metapenaeus monoceros (Fabricius)
(CSIR-NISCAIR, 1982)Growth efficiency (K sub(1) and K sub(2)) increased from 7 to 15% feeding levels, Maximum water content was recorded in starved prawns and the minimum at 20% feeding level On theoretical basis, average daily feeding level ...
