Status and strategy of zooplankton of tropical Indian estuaries: a review
(Plankton Society of Japan, 1987)
Biological observations off Sutrapada, Veraval (Gujarat)
(Trivandrum: University of Kerala, 1987)
Biological production potential off Veraval was evaluated based on the contribution of phytoplankton, zooplankton and benthos. The study was made along three transects covering four months during 1984-85. The mean phytoplankton ...
Dissolved carbohydrate in the central Arabian Sea
(CSIR-NISCAIR, 1987)
Seawater samples (161), collected from 8 depths (0 to 1000 m) at 21 stations were analysed for total dissolved carbohydrate. Dissolved carbohydrate concentrations varied from 0.072 to 1.15 mg.l-1. Carbohydrate concentrations ...
Oxytocic principle of Red alga Amphiroa fragilissima
(Walter de Gruyter, Berlin, 1987)
The crude aqueous methanolic extract of the marine red alga @iAmphiroa fragilissima@@ has been reported as exhibiting oxytocic and spasmogenic activity at a dose of 50 ~kg/ml. The activity is located in the water soluble ...
A device for continuous microscopic examination of aquatic microorganisms
(CSIR-NISCAIR, 1987)
The device consists of a sealed microscopic mount provided with an inlet for liquid medium and an outlet, permitting continuous flow of the liquid. It permits observation of development of marine microorganisms such as ...
Nutrients and phytoplankton production in the Southern Ocean in a section 10 degrees to 52 degrees E in the Indian Ocean
(New Delhi: Department of Ocean Development, 1987)
Variations in the spectral values of specific absorption of phytoplankton
(American Society of Limnology and Oceanography, 1987)
Absorption spectra of laboratory cultures of eight species of phytoplankton were studied. These spectra, normalized per unit of chlorophyll a concentration (specific absorption) show variability in magnitude and spectral ...
