Water quality management in shrimp aquaculture ponds using remote water quality logging system
(School of Industrial Fisheries, CUSAT, India, 2006)Currently an institutional co-operation project funded by NORAD is evaluating different environmental management strategies for sustainable aquaculture in India. A brief description of a remote water quality logging system ... -
Algal-fungal interactions in the marine ecosystem: Symbiosis to parasitism
(CSMCRI, India, 2006)A wide array of partnership exists between algae and fungi. These range from loose commensal association between algae and fungi as in primitive lichens, obligate symbiotic association termed mycophycobioses between the ... -
Primary productivity in the Karwar Bay, Karnataka, west coast of India
(MKK Publication, 2006)The measurement of primary production is of great importance because of its significance to the problems of aquatic ecology and fishery management. The interaction of light intensity, temperature and nutrient levels ... -
Genetic variation in skipjack tuna Katsuwonus pelamis (L.) using PCR-RFLP analysis of the mitochondrial DNA D-loop region
(The Fisheries Society of the British Isles, 2006)A high level of genetic diversity was observed in Katsuwonus pelamis populations from India (h = 0.952, ne = 14.3) and Japan (h = 0.897, ne = 8.9). The log-likelihood (G)-based exact test revealed significant heterogeneity ... -
Gyrineum natator: A potential indicator of imposex along the Indian coast
(Elsevier, 2006)Imposex related studies have used neogastropods as sentinel organism. In this effort, we elucidate the potential of a mesogastropod, Gyrineum natator, for imposex monitoring on the central west coast of India. Observations ... -
Aspects of the biodiversity of brackish water foraminifera

Monsoon driven changes in phytoplankton populations in the eastern Arabian Sea as revealed by microscopy and HPLC pigment analysis
(Elsevier, 2006)Like the rest of the Arabian Sea, the west coast of India is subject to semi-annual wind reversals associated with the monsoon cycle that result in two periods of elevated phytoplankton productivity, one during the northeast ... -
Cell damage and recovery in cryopreserved microphytobenthic diatoms
(Elsevier, 2006)Two pennate microphytobenthic diatoms, Amphora coffeaeformis (Agardh) Kutzing and Navicula transitans var. derasa f. delicatula Heimdal, were cryopreserved and monitored on thawing to track the mechanical injuries and their ... -
Effect of new aeration technology on the bacteriology of shrimp ponds growing Penaeus monodon
(School of Industrial Fisheries, CUSAT, India, 2006)The present study was conducted to evaluate the effects of a HOBAS aeration technology developed by HOBAS Water Engineering in Norway on shrimp ponds in India. Two ponds (P1 and P2) having an area of approx. 0.6 ha located ... -
Salinity-induced survival strategy of Vibrio cholerae associated with copepods in Cochin backwaters
(Elsevier, 2006)The occurrence of Vibrio cholerae in water, sediment and copepods was studied over a wide range of salinity using conventional and polymerase chain reaction (PCR) techniques in the Cochin backwaters. V. cholerae occurred ... -
