(CSIR-NISCAIR, 1982)Distribution of meio- and macrobenthos of muddy bottom deposits at the mouth of Krishna, Godavari, Mahanadi and Hooghly rivers was studied from replicate sampling Total meiofauna ranged from 226 animals/4.5 cm super(2) to ... -
Distribution of Oxycephalidae (Hyperiidea-Amphipoda) in the Indian Ocean- A statistical study
(Oxford and IBH, New Delhi, 1992)Statistical analysis of oxycephalids on coexistence of the species showed two clusters of high affinity in the Arabian Sea, four in the Bay of Bengal, one in the South East Indian Ocean and three in the South West Indian ... -
Distribution of Pelagic Harpacticoid Copepods from the Indian Ocean
(Indian Association for Limnology and Oceanography, 1981)Pelagic harpacticoid copepods have been studied from the International Indian Ocean Expedition collections. Macrosetella gracilis and Miracia efferata were the most common species of harpacticoids with high densities near ... -
Distribution of planktonic decapods with special reference to Acetes from nearshore waters of Bombay
(Indian Fisheries Association, 1982)Distribution and seasonal variation of decapod larvae were studied from eight stations off Versova and Mahim during Nov. 1979 to Dec. 1980. Decapod larvae were encountered throughout the year contributing 7.27% of total ... -
Distribution of Pleuromamma spp (Copepoda-Calanoida) in the northern Arabian Sea
(CSIR-NISCAIR, 1994)Distribution of common marine copepods of genus @iPleuromamma@@ Giesbrecht was studied. Two species, @iP. indica@@ Wolfenden and @iP. gracilis@@ were present in surface and vertical samples (0-500 m). The former was dominant ... -
Distribution of scolecithricidae (Copepoda: Calanoida) in the Indian Ocean
(Intergovernmental Oceanographic Commission, 1998)Ecology and zoogeography of the frequently occurring and widely distributed planktonic copepods collected during the International Indian Ocean Expedition, Scolecithrix danae, Scolecithricella bradyi, S. tenuiserrata, S. ... -
Distribution of suspended particulate matter in the waters of eastern continental margin of India
(CSIR-NISCAIR, 1985)Distribution of total suspended matter (TSM) in surface and near bottom (approximately 5 m above sea bed) waters reveals a wide variation in concentration and composition. TSM varies from 0.05 to 122 mg.l/1 in surface ... -
Distributional characteristics of surface-layer mesozooplankton in the Bay of Bengal during the 2005 winter monsoon.
(NISCAIR, 2014)Present study consists spatial patterns in biomass, abundance and composition of mesozooplankton in Bay of Bengal. Surface samples were collected from a central open ocean transect along 88ºE and western coastal transect ... -
