Plankton Diversity

On the basis of their nutritional requirements Planktonic organisms are classified in to two types. a) Phytoplanktons. b) Zooplanktons. Diversity of Phytoplanktons: Detailed microscopic examination of Phytoplanktons under compound microscope has been carried out and revealed that there were 4 groups consisting of 35 genera of Phytoplanktons in the sample scanned throughout the study period (January 2008 to December 2009). The orderwise Phytoplanktons reported as follows: 1. Chlorophyceae: 15 genera 2. Bacillariophyceae: 7 genera 3. Cyanophyceae: 7 genera 4. Euglenophyceae: 6 genera Diversity of Zooplanktons: Detailed microscopic examination of zooplanktons under compound microscope has been carried out and revealed that there were 4 groups consisting of 25 genera of zooplanktons in the sample scanned throughout the study period (February 2008 to May 2009). The orderwise zooplanktons reported as follows: 1. Rotifera: 10 genera 2. Cladocera: 8 genera 3. Copepoda: 5 genera 4. Ostracoda: 2 genera
