ZOOPLANKTON POPULATION AND PRIMARY PRODUCTIVITY IN PARAPPAR RESERVOIR, KERALAS. Synudeen SahibAbstract Located between latitude 8' 49' and 9017' and longitude 770 16' and 76°24' E. the Thenmala dam built across the Kallada river has created the Parappar reservoir having the distinction of being one of the recently commissioned river basin project in Kerala. Zooplankton population and net primary productivity studies were undertaken from June 1987 to May 1988. Different genera of Zooplankton. noted during the present were Brachionus, Keratella, Lecane ,Allodiaptomus, Mesocyclops, Calanus, Cypris, Chydorus and Alona. Total zooplankton population was maximum during December (11.90%) and minimum during April (0.63%). Net primary productivity varied from 0.50 gc/m3/day (December) ) to 3.80gc/m3/ day (April). A significant negative correlation between net primary productivity and zooplankton population observed in the present study might be due to grazing.
