12/4/2024 12:00:00 AM Charru Mussel: A Silent Threat to Ennore Coast of Tamil Nadu

This article examines the invasion of Charru mussel (Mytella strigata, Hanley, 1843) in the Ennore wetlands of Tamil Nadu, India, highlighting the significant ecological and economic threats posed by this invasive species. Ecologically, the mussels displace native species, alter benthic communities, reduce biodiversity, and filter large volumes of water, which may lead to harmful algal blooms and oxygen depletion. Economically, the invasion disrupts local fisheries by reducing shrimp populations and making fish more difficult to catch, threatening the livelihoods of fishers. The invasion likely resulted from ballast water discharge from ships, weak regulations, and inadequate Environmental Impact Assessments (EIAs). Potential solutions include stricter ballast water regulations, improved EIAs, manual removal, the introduction of natural predators, community monitoring, and advocacy for stronger policies. Immediate action is crucial to prevent irreversible ecological damage and economic losses for the local fishing communities.
