NGT Requests Report on Removal of Mussel Species from Ennore-Pulicat Wetland

  • 09 Oct 2023

Recently, the Southern Bench of the National Green Tribunal (NGT) has directed the Fisheries Department and the Tamil Nadu State Wetland Authority to submit a comprehensive report regarding the eradication of invasive mussel species in the Ennore-Pulicat wetland.

Key Points

  • Concern over Invasive Mussel Species: This invasive mussel has spread extensively, hindering prawns' ability to graze or bury themselves in the sediment. Local residents refer to it as "kaaka aazhi."
  • Its presence is believed to be negatively impacting the locally abundant and commercially valuable yellow clams (manja matti) and green mussels (pachai aazhi).
  • Government's Argument: The government pleader argued that "kaaka aazhi" is not an alien species, as it is listed in the Wildlife Protection Act, 1972 (WPA).
  • Furthermore, the government contended that the NGT lacks jurisdiction to hear matters related to the WPA, as it is not included in Schedule I of the NGT Act.
  • Directive for Government Action: The Bench issued a directive for the government to provide information on whether dredging activities had commenced or if any action plan had been devised by the Fisheries Department.
