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 ...
Vertical distribution of mesozooplankton in the central and eastern Arabian Sea during the winter monsoons
(Cambridge University Press, 1998)
The vertical distribution of mesozooplankton in the central and eastern Arabian Sea was investigated during the winter monsoon in 1995. Samples were analysed from discrete depth zones defined according to oxygen and ...
Swarming of pelagic tunicates associated with phytoplankton bloom in the Bay of Bengal
During the 40th cruise of R V Gaveshani, a large swarm pelagic tunicates associated with a bloom of diatoms and blue green algae was observed off Nagapattinam. The doliolid Dolioletta gegenbauri, Uljanin, the salp Thalia ...
Latitudinal range of epiplanktonic Cahetognatha and Ostracoda in the western tropical Indian Ocean
An account of the chaetognath and ostracod species obtained from zooplankton samples collected along a transect in the Western Indian Ocean between 9 degrees N-20 degrees S and 57 degrees 18'-68 degrees 43'E in January-February ...
The Arabian Sea: Physical environment, zooplankton and myctophid abundance
(Council of Scientific and Industrial Research, New Delhi, 1999)
The Arabian Sea is one of the most productive regions of the world oceans. This productivity mainly results from coastal and open ocean upwelling in summer and cooling effects during winter. Earlier and more recent studies ...
Mesozooplankton biomass, composition and distribution in the Arabian Sea during the fall intermonsoon: Implications of oxygen gradients
Mesozooplankton biomass and distribution of calanoid copepods were studied for the upper 500 m between 3 and 21 degrees N along an open-ocean transect in the Arabian Sea during the Fall Intermonsoon (September-October 1992, ...
Annual variations in zooplankton from a polluted coastal environment
(Indian Association for Limnology and Oceanography, 1980)
Seasonal changes in the composition and distribution of zooplankton from the coastal waters of Trivandrum were studied. The study indicated that the effluent discharged from a nearby titanium dioxide factory did not affect ...
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 ...
