Plankton composition in two estuaries of the Konkan coast during premonsoon season
(Indian Association for Limnology and Oceanography, 1981)
Plankton composition of the Shastri and the Kajvi estuaries of the Konkan Coast were studied during the premonsoon season. Phytoplankton constituents were more abundant at the mid and upper reaches in the former whereas ...
Toxicity of some metals on the fish Therapon Jarbua (Forsskal, 1775)
Hg, V and Pb were more toxic to Therapon jarbua than the other metals studied. Recorded 86 h LC sub(50) for Hg, V, Pb, As, Cu, Zn, Ni and Co was respectively at 0.06, 0.62, 1.23, 3.38, 4.5, 11.0, 19.4 and 52.5 mg.l/1. The ...
Thermocline and zooplankton distribution
Zooplankton biomass along the west coast of India and its effect on the fishery
(Indian Fisheries Association, 1980)
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 ...
Ecological status of the Mahi estuary, South Gujarat
(Gorakhpur: International Society For Environmental Protection, 1988)
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 ...
Studies on the planktonic Decapoda and Stomatopoda (Crustacea) from the western Bay of Bengal
(Indian Association for Limnology and Oceanography, 1988)
Abundance and distribution of decapods and stomatopods were studied, based on 90 samples collected from the western Bay of Bengal (Lat. 09 degrees 58' and 20 degrees 50'N and long. 80 degrees 00'E) between 24 August and 2 ...
Toxic effects of domestic sewage on zooplankton
(National Institute of Oceanography, Goa, 1987)
The toxic effects of raw domestic sewage on different groups of zooplank-ton, was tested in the laboratory for evaluating acute toxicity. 24 hr., LC-50 values for larvae of stomatopods, gastropods and chaetognaths (2-7% ...
