Toxicity of some heavy metals to copepods Acartia spinicauda and Tortanus forcipatus
Copper was most toxic to the species tested followed by cadmium and zinc The estuarine species Acartia spinicauda was more sensitive to the toxicants that the marine species Tortanus forcipatus The 48 hr LC50 values are presented.
Zooplankton biomass and composition in the western Bay of Bengal during late sw monsoon
Copepoda formed the predominant group except in the southern region where a swarm of pelagic tunicates reduced their contribution to only 19% of the total zooplankton count. Decapod larvae occurred in fairly large numbers ...
Chaetognatha of the Andaman Sea
Chaetognatha of the Andaman Sea were studied during 51 and 52 cruises of R.V Gaveshani (Jan to Feb 1979) The area between southeast of Andaman island and north of Nicobar island had relatively higher density Total population ...
Standing stock and biochemical composition of zooplankton in the northeastern Arabian Sea
During November-December 1985 - a period of this study showed significant difference in biomass (dry weight) among the coastal and oceanic waters. Ostracods were the predominant component (47 per cent) in the coastal zone ...
Trace metal concentrations in zooplankton from the eastern Arabian Sea and western Bay of Bengal
(Taylor and Francis, 2008)
Trace metal contents in zooplankton samples were estimated as a part of the Marine Research-Living Resource program at 24 stations in the Bay of Bengal (November, 2002) and 29 stations in the Arabian Sea (September-October, ...
Zooplankton composition of the Kalpeni and Agatti atolls, Lakshadweep archiplago
Composition of zooplankton in the lagoons was quite different from that of the sea and to a large extent, was independent of oceanic influence While copepods were dominant in the sea, meroplankton, particularly brachyuran ...
Influence of upwelling on distribution of chaetognath (zooplankton) in the oxygen deficient zone of the eastern Arabian Sea.
he study addresses the coupled spatial scales in the physico-chemical variables and chaetognaths in the upwelling system of the eastern Arabian Sea during the 2005 summer monsoon. We studied the taxon between 0 and 1000 m ...
Zooplankton composition and diversity in western Bay of Bengal
(Cambridge University Press, 1981)
The biomass of zooplankton ranged from 1-90 ml/100 m3 in the western Bay of Bengal from off Sri Lanka to south of Calcutta in June 1978. The coastal belt between Madras and Visakhapatnam where upwelling is known to occur ...
Impact of oxygen-depleted water on the vertical distribution of chaetognaths in the northeastern Arabian Sea
The influence of a thick layer of oxygen-depleted water (<0.2 ml l sup(-1)) on the abundance and distribution of chaetognaths was investigated in the northeastern Arabian Sea (NEAS), a natural oxygen-deficient system in ...
Zooplankton abundance of the Andaman sea
Zooplankton biomass and abundance of major groups from the Andaman Sea in February 1979 are presented. Average zooplankton biomass is 5.6 ml/100 m3 and is generally poor compared to reported values from east and west coasts ...
