Abstract:

The occurrence and abundance of Microcystis aeruginosa were monitored monthly in eutrophic pond water of Ilamiyakkinar temple pond from July 2014 to June 2015. Some environmental factors such as water temperature, pH, free carbon-dioxide (FCO2), total alkalinity, Dissolved oxygen (DO2), biological oxygen demand (BOD), nitrate (NO2-N) and phosphate are recorded and their relationship with the bloom formation by Microcystis aeruginosa were discussed. The initiation and persistence of Microcystis aeruginosa were founded to be triggered by relatively high water temperature (24 °C to 36.5 °C), pH (7.3 to 8.72) and NO2-N concentration.
