A note on chromosomes of Pontellopsis herdmani and Pontella princeps (Copepoda) from the Laccadive sea
(Indian Association for Limnology and Oceanography, 1984)Pontellopsis herdmani and Pontella princeps (Pontellidae, Calanoida, Copepoda) showed a diploid number of 20 and a haploid number of 10 chromosomes during the spermatogonial metaphase and metaphase II stages. The chromosomes ... -
Nannoplankton from the Bombay-Saurashtra continental shelf of India: An appraisal using cluster analysis
(Indian Association for Limnology and Oceanography, 1984)Nannoplankton data from 28 stations in the northwestern continental shelf of India was subjected to Q-mode cluster analysis. Two biotopes A and B were identified. Although, Gephyrocapsa oceanica was by far, the most abundant ... -
The effect of mercury on the growth efficiency of Tilapia mossambica (Peters)
(Indian Association for Limnology and Oceanography, 1984)Three concentrations of mercury (0.01, 0.04 and 0.4 ppm) were used for experiments on growth efficiency of Tilapia mossambica. Growth efficiencies were determined on a dry weight basis. High concentration of mercury (0.4 ... -
Living benthonic foraminifera in a tidal environment: Gulf of Khambhat (India)
(Elsevier, 1984)Living benthonic foraminifera from the top one centimeter layer from 23 surface sediment samples have been studied. Samples were collected from the tidally affected inner shelf off the Daman Bombay sector of the Arabian ... -

Use of electrophoresis and immunoelectrophoresis in taxonomic and pollution studies
(Indian Academy of Sciences, Bangalore, 1984)Studies were conducted on the electrophoresis of blood serum and eye lens proteins of 5 fishes and immunoelectrophoresis of the soluble lens proteins of 10 fishes. The effects of a toxic pollutant (mercury) on the ... -

Upwelling along the western Indian continental margin and its geological record - a summary
(New York: Plenum, 1983)Upwelling along the western Indian continental margin is recorded each year from Cape Comorin to Cochin and further north up to Goa from June to September during the southwest monsoon. During this upwelling heavy phytoplankton ... -
Some aspects of biology of Bombay duck, Harpodon nehereus (Ham) inhabiting the coastal waters of Goa
(CSIR-NISCAIR, 1984)Intensity of feeding was maximum in Harpodon nehereus of size group 2 (15.1-17 cm) with higher feeding in males than in females. About 44.61% of the fish had empty stomachs. The food of the fish chiefly consisted of ... -
Bromide in some coastal and oceanic waters of India
(CSIR-NISCAIR, 1984)Bromide concentration and bromide/chlorinity ratio are estimated in coastal waters of Goa, Minicoy Lagoon, Western Arabian Sea and Western Bay of Bengal. The influence of precipitation and river runoff on bromide and ... -
Growth of the Black Clam, Villorita cyprinoides (Grey) from Colvale river (Goa)
(CSIR-NISCAIR, 1984)Average monthly growth in shell length was 1.66 mm in Villorita cyprinoides. Relationships of shell length/shell width and shell length/shell breadth showed linear pattern while those of shell length/shell weight and shell ... -
Determination of Cd, Pb and Cu in Mandovi estuary by differential pulse anodic stripping voltammetry
(CSIR-NISCAIR, 1984)Dissolved labile and non-labile (organically associated) concentration of Cd, Pb and Cu in Mandovi Estuary, Goa, India have been measured for 1 y (February 1980 to January 1981). Percentage non-labile form varies from 0-50% ... -

Petroleum hydrocarbon contamination along oil tanker routes in the Arabian Sea
(CSIR-NISCAIR, 1984)Concentration of petroleum hydrocarbons in seawater from the oil tanker route region between 0-25 N and 45-75 E were estimated using UV-absorbance and fluoroscence techniques. Concentrations in surface waters averaged 9.2 ... -
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 ... -
