(NISCAIR, CSIR, 1996)Zooplankton distribution and abundance in neuston layer and water column at 4 stansects between Goa to Gujarat during January-February, 1988 were studied. The ambient water temperature, salinity and dissolved oxygen at ... -
Ichthyoplankton from Andaman and Nicobar seas
(Department of Ocean Development, New Delhi (India), 1996)Ichthyoplankton of the Andaman and NIcobar seas were studied for their spatial, seasonal and day and night variations from 357 zooplankton samples collected during 1986 to 1990. High density of fish larvae was encountered ... -
Photosynthetically available radiation in the central and eastern Arabian Sea
(Current Science Association, Bangalore, India, 1996)In this article, we present the analysis of the photosynthetically available radiation (PAR, 400-700 mm) in the eastern and central Arabian Sea (21 degrees 30'N, 64 degrees E to 12 degrees N, 74 degrees E) during February-March, ... -
Comparative account of benthic community at two different locations in the continental Antarctica
(Department of Ocean Development, India, 1996)Data on faunal communities, abundance and biomass were collected from seven stations in the Queen Maud Land shelf, Lazarev Sea, East Antarctica and three stations in Atca Ice Port, Weddell Sea, West Antarctica. The sampling ... -
Energy source in the developing eggs of the Indian horseshoe crab, Tachypleus gigas (Muller)
(Oxford and IBH, 1996)Wet weight, dry weight, water content, ash weight, soluble and insoluble proteins, carbohydrates, lipids, and glycogen were determined from 0 to 40th day after fertilization of the developing eggs of the Indian horseshoe ... -
Growth of marine yeast on different strength of stress solutes
(Department of Ocean Development, New Delhi (India), 1996)Sixteen isolates of marine yeasts belonging to genera Candida, Debaryomyces, Rhodotorula and Saccharomyces, isolated from the (EEZ) of India were screened for their growth on different concentrations of sodium chloride ... -
Zoosporic fungal parasites of marine biota
(M D Publications, New Delhi, India, 1996)There are four criteria set forth in Koch's postulates which are essential to prove the causal organism of any disease in nature. These are: (1) association of an organism constantly in all the diseased specimens, (2) ... -
Ecosystem characterization in Indian Ocean sector, Antarctica
(Department of Ocean Development, India, 1996)High Chl a) values characterized the surface water (0.445-2.085 mg m sup(-3)) and column (14.63-105.46 mg m sup(-2)). The rate and magnitude pattern of production varied under pack ice influence and also in offshore region. ... -
Studies on the microzooplankton from the central and eastern Arabian Sea
(Current Science Association, Bangalore, India, 1996)Numerical abundance and composition of microzooplankton in the upper 200 m were studied from the central and eastern Arabian Sea during three seasons. Protozoans, comprising of ciliates (loricates and aloricates), flagellates ... -
