Phytoplankton as Biological Indicators in Lentic Hydrosphere from Gadhinglaj

The species composition, distribution and abundance of phytoplankton, in water body, found depend upon the chemical and physical properties of water. In aquatic organisms, planktons were most sensitive component of the ecosystem and signal of environmental disturbances. Apart from primary production, phytoplankton plays an important role in food web of herbivorous animals and act as biological indicators for water quality. Two lentic systems Nool pond and Yenechiwandi lake from Gadhinglaj tahsil were assessed for seasonal variations of Phytoplankton population and physico¬chemical parameters such as pH, Temperature, Dissolved Oxygen, Free Carbon dioxide, Hardness, Chloride, Alkalinity, Nitrate, Phosphate with base level contamination of heavy metals Physico-chemical parameters and heavy metal contamination which has impact over the animal diversity in study region. Attempt was made to compare the water quality of aquatic habitats for pollution status.
