Neuston composition in central Arabian Sea
(CSIR-NISCAIR, 1989)
Composition of neuston in the Arabian Sea (lat. 16-19 degrees N., long. 60-72 degrees E) was studied. The standing stock ranged between 1.5 and 49.3 ml (100 m2)-1. Copepoda was generally the dominant group, forming on ...
Chaetognaths of the Potengi estuary (Natal, Northeast Brazil)
(Universidade Federal do Rio Grande, 1988)
Studies on selected biological parameters off Mithapur (Gujarat)
(Indian Fisheries Association, 1988)
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 ...
Concentration and toxicity of some metals in zooplankton from nearshore waters of Bombay
(CSIR-NISCAIR, 1985)
Zooplankton samples collected from 4 stations located in the nearshore waters of Bombay were analysed for Cu, Co, Mn, Ni and Cd. Concentrations of Co, Mn and Ni were more in copepods and gelatinous organisms than in mysids ...
Diurnal variation of zooplankton in Malad creek, Bombay
(CSIR-NISCAIR, 1984)
Variation in zooplankton biomass and composition in relation to the prevailing hydrographical conditions was studied for 24 h in Malad Creek, Bombay, Maharashtra, India, which was highly polluted by sewage. The adverse ...
Distribution of phytoplankton pigments in Auranga, Ambika, Purna and Mindola estuaries of Gujarat
(Indian Association for Limnology and Oceanography, 1984)
Estimation of phytoplankton pigments in four estuaries of South Gujarat indicates that all are fairly productive systems. Mean surface values of pooled chlorophyll fractions for Auranga, Ambika, Purna and Mindola were ...
Diurnal variation of zooplankton off Versova (Bombay)
(Indian Association for Limnology and Oceanography, 1984)
Physicochemical parameters and diurnal variaion of zooplankton were studied off Versova on 17/18 February 1981. Salinity and dissolved oxygen showed limited variation during the period of study. Nutrient values followed ...
Toxicity of some metals on the fish Therapon Jarbua (Forsskal, 1775)
(CSIR-NISCAIR, 1983)
Hg, V and Pb were more toxic to Therapon jarbua than the other metals studied. Recorded 86 h LC sub(50) for Hg, V, Pb, As, Cu, Zn, Ni and Co was respectively at 0.06, 0.62, 1.23, 3.38, 4.5, 11.0, 19.4 and 52.5 mg.l/1. The ...
Primary productivity in nearshore waters of Thal, Maharashtra coast
(CSIR-NISCAIR, 1983)
Primary productivity off Thal, Maharashtra, India was evaluated at 3 stations during Feb. 1980 to Jan. 1981. The area was quite turbid and the euphotic zone never exceeded 2.5 m. Column production ranged from 0.69 to 605.21 ...
