Researchers have sounded the alarm for urgent conservation efforts to safeguard the diverse fish species inhabiting the Thamirabarani river in Tamil Nadu. This ancient water body, home to six endangered species, faces a grave threat from invasive species and habitat disruption. A recent study published in the Indian Journal of Animal Sciences underscores the need for extensive research programs to mitigate these threats.
Originating from the Podhigai hills and traversing Tirunelveli and Thoothukudi districts, the Thamirabarani river boasts a rich variety of fish, comprising 125 species. Among them, 72 are freshwater species and 53 are estuarine species, with 80 species serving as food sources and 32 considered ornamental. However, the proliferation of invasive species like the African sharptooth catfish, Pleco tank cleaner catfish, and Tilapia has caused a decline in native species, leading to biodiversity loss and potential health hazards.
The construction of dams along the river further exacerbates the situation by disrupting natural fish migration patterns, impacting breeding and population dynamics. HS Mogalekar, the study’s author, highlights the river’s exceptional diversity, emphasizing the need for comprehensive research on its fish diversity.
Nilanjan Mukherjee, a research consultant at ATREE, stresses the importance of detailed studies to inform effective conservation strategies. Governmental support for further exploration into the Thamirabarani river’s fish diversity is critical for preserving this vital ecosystem.
As the Thamirabarani river holds significant importance in Tamil Nadu’s natural heritage, concerted efforts are required to address the threats posed by invasive species and habitat disruption. By prioritizing research and conservation initiatives, we can ensure the survival of endangered species and maintain the health of this precious ecosystem. Collaboration between government bodies, researchers, and conservationists is essential for securing a sustainable future for the Thamirabarani river and its inhabitants.
