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 ...
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 ...
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 ...
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 ...
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 ...
Plankton composition in the coastal waters between Jaigarh and Rajapur along west coast of India
(Indian Association for Limnology and Oceanography, 1980)
Diatoms dominated the phytoplankton population in the Konkan coastal waters. Rhizosolenia spp., Ceratulinia sp., Ditylum spp., Navicula sp. and Thalassiothrix spp. were the dominant diatoms observed in this area. Blue-green ...
Zooplankton variability in the Zuari estuary, Goa
(Indian Association for Limnology and Oceanography, 1983)
Short term variability in the secondary production and composition of zooplankton were studied during February to March 1979 by collecting zooplankton every alternate day from a station located near the mouth of Zuari. ...
