A new genus and species of Heteromysini (Crustacea- Mysidacea) from the backwater of Kochi (Kerala, India)
(Taylor and Francis, 2007)Kochimysis pillaii, a new genus and species of Heteromysini collected from the backwater of Kochi (Kerala, India), is described. The new genus is closely related to the genus Deltamysis but is distinguishable from the ... -
Adaptations in Phytoplankton to Changing Conditions in Tropical Estuaries
(Indian Association for Limnology and Oceanography, 1980)Experimental studies on phytoplankton organisms from Cochin backwaters (a tropical estuary) have shown that many algal forms are adapted to changing conditions of salinity, light and nutrients. Photosynthesis in 12 species ... -
Anomalous behaviour of uranium isotopes in backwater sediments of Zuari river
(Elsevier, 1983)The surface leaching of the labile component of uranium has been carried out in estuarine sediments of Zuari River in Goa, India The measurements of alpha activities of sup(238) U, sup(235) U and sup(234) U in the leachates ... -
Bioaccumulation of toxic metals by fish in a semi enclosed tropical ecosystem
(Taylor and Francis, 2006)Concentrations of Zn, Cd, Pb, and Mn in different tissues of 17 species of fish from a tropical estuary (Cochin backwaters) are presented. The metal electivity index (MSI) was found to be a better tool compared with the ... -
BOD-DO modeling and water quality analysis of a waste water outfall off Kochi, west coast of India
(Elsevier, 2006)Water quality scenarios around an offshore outfall off Kochi were simulated using MIKE21 water quality model, assuming a high Biochemical Oxygen Demand (BOD=50 mgl sup(-1)) effluent discharge. The discharge is introduced ... -
Cochin backwaters: A sad story of manipulation
(The Royal Swedish Academy of Sciences, 1997)Cochin backwaters, along the south west coast of India have been altered several times for various causes and the system has undergone tremendous environmental changes as a consequence developmental activities and associated ... -
Cochin backwaters: An introduction to the system, prior studies, historical trends and future implication
(Kalpana Corporation, Varanasi, India, 1994)Studies over the last 2 decades in the Cochin backwater system in India are reviewed to have an integrated profile with a point to evaluate future development projects in terms of potential consequences to the estuarine ... -
Ecology of the Coexisting Copepod Species in Cochin Backwaters
(Indian Association for Limnology and Oceanography, 1980)Association between the common copepod species of Cochin backwaters were analysed. Grouping of the low saline and medium saline species generally stood separate from the high saline species. A high degree of correlation ... -
Environmental conditions of some paddy cum prawn culture fields of Cochin backwaters, southwest coast of India
(CSIR-NISCAIR, 1988)Temperature, salinity, pH, dissolved oxygen, inorganic phosphate, ammonia, nitrate and nitrite of seasonal and perennial prawn culture fields from 3 areas of Cochin backwaters are studied. Area 1 is a region least affected ... -
Estuarine characteristics of the lower reaches of the River Periyar (Cochin backwater)
(CSIR-NISCAIR, 1986)Lower reaches of river Periyar were studied to assess longitudinal extent of salt water intrusion into the system during different seasons and also its effect on the flushing of pollutants introduced by the industries. ... -
Features at some significant estuaries of India
(Oxford and IBH, New Delhi, 2001)The river basins of India are classified into three groups on the basis of catchment areas: (1) above 20,000 km sup(2), (2) 2,000-20,000 km sup(2) and (3) less than 2,000 km sup(2). The total number of rivers under first ... -
Foraminiferal fauna from the Cochin backwaters: Biological indicators of man-made changes in the environment
(K.R. Publishers, Udaipur, 1996)Sixty foraminiferal species belonging to 38 genera and 23 families have been recorded from grab sediments of the Cochin backwaters. Of all the species Ammonia baccarii is the most dominant and successful form in the throes ... -
Fungal infection in the tiger prawn (Penaeus monodon) and in other crustaceans from the Cochin Backwaters
(Indian Association for Limnology and Oceanography, 1980)Infection of the two species of fungi (Phycomycetes) in the tiger prawn (Penaeus monodon) and three species in amphipods (Gammarus sp.) and tanaeidaceans (Apseudes sp.) was observed. Of the two pathogens in the shrimp, ... -
Geochemistry of surficial sediments along the central southwest coast of India - Seasonal changes in regional distribution
(Coastal Education and Reserch Foundation, 2003)The coastal sediments (129 samples) of central- southwest coast of India, in and around Cochin, the second biggest industrial city along the west coast of India, were analyzed for their textural and geochemical fractions ... -
Nutrients of the Cochin backwater in relation to environmental characteristics
(Springer, 1969)The nutrient distribution of the Cochin Backwater was studied at 6 stations throughout the year The depth profiles of phosphorus (inorganic and organic), nitrogen (nitrate and nitrite) and silicon, showed a marked seasonal ... -
Phytoplankton distribution in Cochin backwaters - a seasonal study
