In this study abundance and composition of zooplanktons in the Indus River Estuary was conducted to examine habitat characteristics its impact on tiny organisms. Overall 30,656 individuals were identified segregated into seven major groups including Copepods, Cnidarians, Decapods, Mollusk, Pisces, Amphipods Chaetognaths. For better understanding they further divided eighteen planktonic categori...
The present study concerns seasonal variations, correlation coefficient and biodiversity indices of zooplanktons during January-December, 2008 in the Harsool-Savangi dam, Aurangabad, India. A total of 25 genera were recorded of which 10 were Rotifers, 8 Cladocerons, 5 Copepods and 2 Ostracods. Present study revealed maximum percentage wise compositions of Rotifers at north site were 58.28%, Cla...

Among Copepod, 48%, 40% 12% Calanoid, Cyclopoid Harpacticoid respectively. also found 2 Decapod, Rotifer, Cladocera, 1 Chaetognatha Stom...
Ponds are natural water sources that are used by man for various purposes. Zooplankton constitutes an important food item for fishes . Zooplankton also play an important role and serve as bioindicators as well as to assess the pollution status of water .In this present study, we tried to asses the zooplankton species richness, diversity and evenness and to state the condition of a freshwater tr...
Seasonal variation of the plankton populations with some water quality parameters of Borobila beel, Rangpur district was carried out during July 2003 to June 2004. Total plankton ranged from 98.3×104 to 35.0×105 cells/l with mean values of 19.67±9.77×105 cells/l. A total of 51 genera of planktons were recorded belonging to Chlorophyceae, Bacillariophyceae, Cyanophyceae, Euglenophyceae, Dinophyc...
Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities.
