Analysis of Zooplankton Diversity and Limnological Parameters of Salchapra Anua, an Oxbow Lake in Silchar, Assam

Zooplankton diversity and Limnological parameters are the most important criteria for determining the suitability of an aquatic ecosystem for any kind of aquacultural programme. Water quality of the freshwater habitats provides information about the existing resoureces which depend on physico-chemical parameters and biological features. Some of the limnological parameters and Zooplankton composition of Salchapra Anua was studied for a period of six months from October, 2016 to March, 2017. The limnological parameters of the study site was found to be highest during the month of October, 2016. A total of 15 taxa belonging to three groups were recorded during the investigation of which 5 taxa were from Cladocera group, 4 from Copepoda and 6 taxa from Rotifera group. The highest Zooplankton abundance was recorded from the site during the month of October, 2016 and lowest during the month of February, 2017. Cladocera contribute highest percentage of 43% of the total Zooplankton composition followed by 42% of Rotifera and 15% of Copepoda. Presence of highest percentage of Cladocera again depicts the better condition of the water body and can be used for aquacultural program.
