Distribution and diversity of copepods in the Mandovi-Zuari estuarine system, Goa
Truly estuarine and estuarine-marine species were the major components of copepods Neritic and limnetic species were stragglers in this environment and showed fortuitous distribution Monsoonal cycle induced seasonal rhythm ...
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 ...
Zooplankton along the Tamil Nadu coast
(Indian Association for Limnology and Oceanography, 1981)
Zooplankton abundance along two sectors at Cape Comorin and Tuticorin of Tamil Nadu Coast, southeast coast of India was studied. High biomass contributed by Ostracods, Salps, Chaetognaths etc., were observed along Tuticorin ...
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 ...
Zooplankton studies in Visakhapatnam harbour and nearshore waters, east coast of India
Distribution of zooplankton biomass in the waters studied showed remarkable variations. The faunal composition was very diverse and the number of species present was more especially during late pre- and post-monsoon seasons ...
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 ...
Swarming of Creseis acicula Rang (Pteropoda) in the coastal waters of Goa
(Indian Association for Limnology and Oceanography, 1983)
Swarms of Creseis acicula Rang (Pteropoda) were observed in the coastal waters of Goa regularly in October, from 1976 to 1980. The highest biomass value obtained for this species was 494 ml/100 m@u3@@, forming 96% of ...
Total mercury in water, sediments, and animals along the Indian Coast
Total mercury (Hg) in water, sediments and animals along the coast of India is estimated. Water samples were collected on board of R.V. Gaveshani.The zooplankton samples were collected by Indian Ocean Standard Net and Heron ...
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 ...
