Biological characteristics of the Vashishti Estuary, Maharashtra (west coast of India)
(NISCAIR, CSIR, 1998)The estuary and coastal nearshore regions sustained fairly high concentration of chlorophyll a (av. 3.1 mg/m sup(3)) and primary productivity (av. 89.9 mgC/m sup(3)/h). High rate of primary productivity wos observed in the ... -
Biological investigations of Indian phaeophyceae: 17. Seasonal variation of antibacterial activity of total sterols obtained from frozen samples of Sargassum johnstonii Setchell et Gardner
(Seaweed Research and Utilization Association, 1998)From lipid fraction of frozen samples of Sargassum johnstonii unsaponifiable part was extracted with diethyl ether to isolate total sterols. The extracted sterols were obtained for a period of nine months and tested against ... -

(Cambridge University Press, 1998)Descriptions of Indoerythrops typicus, new genus and new species, and Pleurerythrops inscita, new record, from Indian waters are given. The new genus is distinguishable from the allied genera of the tribe Erythropini in ... -
Geographical variation in the distribution of different calanid species in the Indian Ocean
(Intergovernmental Oceanographic Commission, 1998)The species composition of Calanidae in the Indian Ocean was studied from zooplankton collections taken between 24 degrees N to 40 degrees S and 20 degrees E to 120 degrees E. Nannocalanus minor was widespread with high ... -
Phytoplankton characteristics in a polluted Bombay Harbour-Thana-Bassein creek estuarine complex
(NISCAIR, CSIR, 1998)Annual variations in phytoplankton characteristics were studied from Bombay Harbour-Thana creek-Bassein creek (BHTCBC) estuarine confluence to assess the levels of pigment concentration, productivity and, qualitative and ... -
Subtidal benthic macrofauna of the Mangalore Coast, west coast of India
(NISCAIR, CSIR, 1998)Subtidal macrobenthic fauna from the Mangalore Coast was studied from the shelf areas between the old Mangalore Port and Suratkal, covering an area of approximately 40 km sup(2). Benthic bivalves were the most abundant ... -
Structure of major seagrass beds from three coral reef atolls of Lakshadweep, Arabian Sea, India
(Elsevier, 1998)Detritus-based marine ecosystems such as mangrove and seagrass are of immense ecological importance. Major seagrass meadows from three coral atolls of the Lakshadweep group (Arabian Sea) were studied for their floral ... -

Severe fish mortality associated with 'red tide' observed in the sea off Cochin
(Current Science Association, 1998)Severe fish mortality associated with the "red tide" phenomenon caused by Noctiluca blooms was observed in the sea off Cochin, Kerala, India at depths less than 40 m. The dead fish, almost entirely comprised of the threadfin ... -
Shrimp farming in estuarine environment: Points to ponder
(Rajiv Gandhi Centre for Aquaculture, Subramaniyapuram (India), 1998)The capture fishery resources have almost reached a sustainable yield and the production can only be supplemented through culture fishery practices. This is particularly true in case of marine shrimps. The annual foreign ... -
