Studies on water quality and zooplankton community of the Panchganga river in Kolhapur city.

ABSTRACT

The present investigation deals with the zooplanktons together with water quality of Panchganga river, in Kolhapur city, Maharashtra. This investigation was undertaken for a period of one year. The river Panchganga is a highly contaminated downstream with untreated sewage and industrial effluents, while flowing through Kolhapur city. The high value of CO2, BOD, COD, phosphate, nitrate, Zn, Fe, Cu and low value of DO at discharge zone indicates increase in organic pollution as we go down the river strech Site III and Site IV. The discharge zone is dominated by pollution tolerant zooplankton species such as Brachionus, rotifera, Brachionus keratella, Filinia, Anuraeopsis etc.
