Studies on calcium, magnesium and sulphate in the Mandovi and Zuari river system (Goa)
(CSIR-NISCAIR, 1981)Distribution of calcium, magnesium and sulphate have been examined in the tide-dominated Mandovi and Zuari river systems. Calcium and magnesium appear to take some part in the bio-geochemical cycles of the rivers and behave ... -
Arsenic in water, plankton and sediments off Goa coast and adjacent regions
(CSIR-NISCAIR, 1981)Arsenic content was estimated in water, plankton and sediments in the region between 14 degrees 40'N and 15 degrees 50'N surrounding Goa coast. Of the total arsenic content in water (1.65 - 4.78 mu g/litre; av. 3.09 mu ... -
Environmental Characteristics of the Mandovi-Zuari Estuarine System in Goa

Plankton Studies in the Estuarine and Nearshore Regions of Mandovi and Zuari
(CSIR-NISCAIR, 1981)Biological and chemical data collected for the preparation of a masterplan for pollution control in the rivers Mandovi and Zauri and the adjacent coastal area were processed to study the ecological conditions. Both ... -

Developmental Characters of Bothid Flatfishes of the Genus Psettina
(Le Conseil, 1981)The developmental characters of two species of flatfishes @iPsettina brevirictis@@ and @iP. iijimae@@ have been discussed. Some common and different characters found during the developmental series have been highlighted. ... -
Distribution of Phytoplankton and Chlorophyll a around little Andaman Island
(CSIR-NISCAIR, 1981)Surface chl a and phaeopigments of the whole phytoplankton varied from 0.02 to 0.085 mg/m3 (av. 0.043) and 0.017 to 0.068 mg/m3 (av. 0.039)respectively; chl a of the nannoplankton fluctuated from 0.013 to 0.085 mg/m3(av.0.034) ... -
Microbiological Studies in the Mandovi-Zuari River System
(CSIR-NISCAIR, 1981)Total heterotrophic and coliform bacteria were surveyed during October 1977 to September 1978 from 9 stations each along the rivers Mandovi and Zuari and 3 along the coast of Goa. Total heterotrophic population showed wide ... -
Distribution of Nutrients in the Western Bay of Bengal
(CSIR-NISCAIR, 1981)Distribution of phosphates and nitrates in relation to some physico-chemical features of the western Bay of Bengal during August-September 1976 indicated marked regional variations. The mixed surface layer which was ... -

Plankton Composition in two Estuaries of the Konkan coast during Premonsoon Season
(Indian Association for Limnology and Oceanography, 1981)Plankton composition of the Shastri and the Kajvi estuaries of the Konkan Coast were studied during the premonsoon season. Phytoplankton constituents were more abundant at the mid and upper reaches in the former whereas ... -
Benthic macrofauna of the Andaman Sea
(CSIR-NISCAIR, 1981)Macrobenthic fauna in the depth range 11 to 2150m comprised 22 faunal taxa. Of these, the polychaetes were the most dominant group and contributed 76.8%. Distribution of macrofauna was substrate specific with maximum (410m ... -
Seasonal Changes in Meat Weight and Biochemical Composition in the Black Clam Villorita Cyprinoides (Grey)
(CSIR-NISCAIR, 1981)Seasonal changes in meat weight and biochemical composition are associated with reproduction, storage and utilization of reserves. The main period of increase in biochemical constituents corresponds to gametogenesis and ... -
Microbiological Studies on the Sediments of Andaman Sea
(CSIR-NISCAIR, 1981)Total bacterial population in the sediments widely fluctuated from 2.1x 10 3 to 3.7 x 10 6. There was no significant correlation between organic carbon values and heterotrophic activity. Ratio of gram positive to gram ... -
Food Components of the Andaman Sea
(CSIR-NISCAIR, 1981)Detrital carbon in the Andaman Sea constitutes about 92% of the total particulate carbon while phytoplankton and zooplankton constitute small fractions of the total suspended matter. Latitudinal relationship between ... -
Meiofauna of the Andaman Sea
(CSIR-NISCAIR, 1981)Total meiofauna of the Andaman Sea, in the depth range 30-2150m was between 68 and 438/10cm2 (X-bar = 247.8). The biomass was within the range 3.57 and 32.8mg/10cm 2 (X-bar = 14.46). faunal components were maximum in sandy ... -
A Preliminary Account on the Distribution of Decapod Larvae in the Konkan Waters
(Indian Association for Limnology and Oceanography, 1981)Decapod larval distribution in Konkan coastal waters was studied during the premonsoon season (March-April). Sergestid was the largest group forming 80.55% of the total decapod crustacean larvae. Penaeid larvae constituted ... -
Waste water Discharge and its effect on the Quality of Water of Mahim Creek and Bay
(Indian Association for Limnology and Oceanography, 1980)Coastal environment around Mahim was monitored to evaluate the effects of domestic and industrial waste water discharge in Mahim Creek, Maharashtra, India. Vertical salinity and DO gradient occasionally observed in the ...
