(ICAR, New Delhi, 1991)Based on the analysis of 204 zooplankton samples from the stratified depths in the Indian Ocean collected during the International Indian Ocean Expedition (IIOE), the distribution of the genus Pleuromamma indica, P. gracilis, ... -
Benthic macro and meiofauna of seagrass (Thalassia hemprichii) bed at Minicoy, Lakshadweep
(CSIR-NISCAIR, 1984)Macrofauna, comprising 9 groups, was dominated by polychaete worms, while meiofauna, comprising 10 groups, was dominated by nematodes Densities of both macro and meiofauna were higher near the shore where biomass of Thalassia ... -
Benthos
(Oxford and IBH, New Delhi, 2001)Benthic organisms are sessile and sedentary in nature. True benthos can be divided into two groups - epifauna and infauna. They comprise major invertebrate phyla. Benthic organisms are separated into micro, meio, macro and ... -
Benthos of Cochin backwaters receiving industrial effluents
(CSIR-NISCAIR, 1989)Faunal composition of benthos and its spatial and temporal distribution at 9 stations in the northern limb of the Cochin backwaters are studied. An industrial belt is located about 18 km upstream of barmouth, and the ... -
Biodiversity of benthic polychaetes from the coastal waters of Paradip, Bay of Bengal
(Annon., 2007)Polychaete communities of the subtidal waters off Paradip, Orissa, India (Lat, 20 degrees 05 minutes - 20 degrees 20 minutes N and Long. 86 degrees 35 minutes - 86 degrees 60 minutes E) in the Bay of Bengal were studied ... -
Biology of corals and coral reefs
(Oxford and IBH, New Delhi, 2001)This chapter deals with biology of corals, coral reefs (in general) and coral reefs of the Indian Ocean. Biology of corals is lucidly dealt with, beginning from the clarification on hermatypic and ahermatypic forms. A ... -
Biomass and biochemical composition of zooplankton from northwest Bay of Bengal during January 1990
(NISCAIR, New Delhi, 1993)Biomass, proximate composition, organic carbon and calorie content of assorted zooplankton from the surface waters were studied. Day and night stations revealed significant difference in biomass (displacement volume, dry ... -
Bothid larvae (Pleuronectiformes-Pisces) of the Indian Ocean
(Council of Scientific and Industrial Research, New Delhi, 1999)The larvae of bothids were found to be sparsely distributed in the Indian Ocean, being only 7.6% in IIOE collections (1960-65) and 13.5% in FORV Sagar Sampada (1986-90) samples. They were confined mostly to the coastal ... -
Characteristics of coastal waters of the western Bay of Bengal during different monsoon seasons
(CSIRO, Australia, 1992)Physical characteristics of waters along the eastern coast of India up to offshore distances of 400 km have been investigated during the seasons of the north-easterly and south-westerly monsoons in light of relevant observed ... -
Chlorophyll 'a' and particulate organic carbon in relation to some physico-chemical parameters along southwest coast of India
(Marine Biological Association of India, 1997)Chlorophyll 'a', Particulate Organic Carbon and other environmental parameters were studied along Kerala Coast during October 1987 and 1988. High chlorophyll 'a' content at surface water and decreasing trend towards offshore ... -
Chlorophyll and sediment distribution study of the Gulf of Kutch using remote sensing
(PORSEC 2002 Secretariat; Bogor; Indonesia, 2002)This study is largely based on the resulting series of SeaWiFS images and OCM images of Gulf of Kutch, which shows chlorophyll distribution on about 160 (cloud-free) dates between October 1998 and August 2001 period and ... -
Communities and coexistence of benthos in northern limb of Cochin Backwaters
(NISCAIR, New Delhi, 1991)Occurrence and coexistence of benthic communities of 9 stations in the northern limb of Cochin Backwaters (Kerala, India) where an industrial belt (mostly chemical industries) is located are studied. Polychaetes with 30 ... -
Composition of heteropods in the Arabian Sea
(Department of Ocean Development, New Delhi (India), 1996)Distribution of species of Atlantidae, Carinariidae and Pterotracheidae in the Andaman Nicobar Sea is discussed in this paper based on samples of FORV Sagar Sampada. Oxygrus Keraudreni and Protatlanta souleyeti are reported ... -
Coral reef ecosystem
(SAGE, India, 2003)Briefly discuss coral reefs in general and the Indian reefs in particular. While the ecology, growth forms and distribution of the reefs are well known and need only be mentioned briefly, the constraints to their sustainability ... -
Distribution and abundance of copepods in the pollution gradient zones of Bombay Harbour-Thana Creek-Bassein Creek, west coast of India
(NISCAIR, CSIR, 1997)Forty six species of copepods were identified, of which, 40 belonged to Calanoida with an overall dominance of Acartiidae. Acartia spinicauda, A. centrura and Centropages dorsispinatus were the common species throughout ... -
Distribution and abundance of pelagic shrimps from the deep scattering layer of the eastern Arabian Sea
(The National Shellfisheries Association, 2006)The sonic scattering layer (SSL) or deep scattering layer (DSL) of the eastern Arabian Sea of India is found in depths between surfaces to 750 m with varying thicknesses and in multiple layers. There is a distinct resident ... -
Distribution and diversity of marine flora in coral reef ecosystems of Kadmat Island in Lakshadweep archipelago, Arabian Sea, India
