New Freshwater Fish Species in Western Ghats

Recent research from the Centre for Peninsular Aquatic Genetic Resources in Kochi has revealed two new species of freshwater fish in the Western Ghats. The species, Labeo uru and Labeo chekida, were identified after resolving the long-standing taxonomic confusion surrounding Labeo nigrescens. This discovery puts stress on the ecological significance of the Western Ghats, a recognised biodiversity hotspot.

Background of the Discovery

Researchers utilised morphological analysis on historical specimens and fresh samples from rivers in Kerala and Karnataka. The study aimed to clarify the identities of species first described over a century ago.

Details of the New Species

Labeo uru was discovered in the Chandragiri River and is named after a traditional wooden dhow for its sail-like elongated fins. Labeo chekida, known locally as ‘kaka chekida’, inhabits the Chalakudy River. Both species are endemic to their respective river systems, denoting the unique biodiversity of the Western Ghats.

Threats to Biodiversity

The study warns of threats posed by dams and habitat destruction to fragile ecosystems. These activities jeopardise the survival of unique species and disrupt the ecological integrity of the rivers. The researchers emphasise the need for conservation efforts to protect these habitats.

Future Research Directions

The research team believes that the Western Ghats will reveal more undiscovered species. They call for collective efforts from researchers and conservationists to explore and document the region’s biodiversity. About these ecosystems is vital for their preservation.
