Assessment of water quality parameters and zooplankton assemblage in River Tons (a tributary of river Yamuna in Uttarakhand, India)

Fouzia Ishaq, Amir Khan

The assessment of physico-chemical parameters of River Tons (a tributary of RiverYamuna in Uttarakhand India) and their influence on zooplankton composition and abundance were investigated at three stations for one year fromAugust 2011 to July 2012. The diversity was not high and only four groups of zooplankton were found which includes Protozoa with ten genera, Rotifera with eleven genera, Copepoda with six genera and Ostracoda with two genera only. Rotifera was dominating followed by protozoa, copepoda and ostracoda. The total zooplankton was more prevalent at site I during the study period. The physico-chemical factors and habitat conditions of River Tons strongly influence the generic composition and population density of zooplankton. Hence it is important to prevent the ecological conditions of River Tons and any water ecosystem for the better status of zooplankton and other aquatic diversity.
