Chennai port authority targets October finish for invasive mussel removal

Authorities in Chennai have launched a targeted dredging campaign to combat an invasive mussel species that has proliferated in the Ennore backwaters, a vital water body adjacent to one of India's major ports. The Water Resources Department has identified the stretch between Kattupalli and Puzhuthivakkam as particularly affected by the invasive mollusks, which pose risks to navigation and local ecosystems.

The dredging operation is designed not only to deepen the channel but also to physically remove the invasive mussel colonies that have accumulated along the waterway. Officials have set an ambitious timeline to complete the removal work by October, though the project spans multiple kilometers of backwater terrain.

Invasive mussels have proven problematic in Indian waterways, attaching themselves to infrastructure and organic matter, often blocking water intake systems and damaging ecosystem balance. The Ennore backwaters, which connect to the Chennai port complex, require regular maintenance to ensure navigability and environmental health.

The dredging initiative represents part of broader efforts to manage invasive aquatic species in India's coastal regions. Environmental officials hope the removal operation will prevent further spread of the mussels to adjacent water systems while restoring the functional capacity of the backwater channel. The project's success could serve as a model for similar conservation efforts elsewhere along India's coastline.
