The present study was carried out for diurnal variations of water quality parameter in Kundawada lake of Davangere district for 24 hr at 3 hr interval commencing from 6.00A.M of 6th January 2010 to 6.00AM 7th January 2010. Large fluctuations were noted in dissolved oxygen during day time (12.5 ppm) and oxygen was depleted during night (3.4 ppm). The pH was increased at day time and decreased at night time. However, phytoplankton did not show any apparent diurnal variation except microcystis species. Among zooplankton, Daphnia and Cyclops showed diurnal variation but other zooplankton species did not show any diurnal movement. © 2012 - Kalpana Corporation. Source
