ABSTRACT

The present study was carried out on the diversity of plankton in relation to physico-chemical parameters with respect to pollution status of two perennial ponds of Mehsana, Gujarat. The study was conducted in the month of February 2018. There were sixteen species identified belonging to cyanophyceae, bacillarophyceae and chlorophyceae. We recorded the high value of physico-chemical parameters and low phytoplankton diversity in the Chhatiyarda pond. Whereas we found low value of physico-chemical parameters and high diversity in the Panchot pond. The identified species Oscillatoria, Gleocapsa, Spirulena, Nostoc, Merismopodia, belongs to Cyanophyceae, species such as Navicula, Synedra, cymbella, Nitzschia, Amphiplura were belongs to Bacillariophyceae, while closterium, spirogyra, zygnema and Oedogonium, ulothirx were of chlorophyceae. It is remarkable that the chlorophyceae population were found as the most abundant group in both ponds.

Keywords: Diversity, physico-chemical parameters, phytoplankton.
