Algal Bloom in Pamban

September 13 , 2019 2031 days 1288 0
  • A 10-km stretch of the shoreline between Kunthukal in Pamban and Vedalai in the Gulf of Mannar turned green and witnessed mass fish deaths.
  • Central Marine Fisheries Research Institute conducted tests and concluded that the sudden blooming of ‘Noctiluca marine microalgae’ was to blame for the incident.
  • The high temperatures and good organic conditions in seawater had provided a conducive environment for the ‘green algae’ to breed and release spores.
  • Fishes have died due to ‘gill choking’ and had died of oxygen depletion and breathlessness.
