In a recent scientific advancement, researchers from the ICAR-NBFGR (National Bureau of Fish Genetic Resources), Lucknow, have identified and described two new species of freshwater fish from the rivers of the Western Ghats, an area globally recognized for its exceptional biodiversity. The two newly discovered species, Labeo uru and Labeo chekida, represent a notable addition to the documented aquatic biodiversity of the region. The findings, along with a detailed scientific analysis, have been published in the Indian Journal of Fisheries.
The species Labeo uru was discovered in the Chandragiri River. This fish is characterized by a distinctive sail-like dorsal fin, a morphological feature that sets it apart from other known species within the genus. Its unique fin structure is a defining characteristic that aided researchers in establishing it as a new species.
Meanwhile, Labeo chekida, a small, dark-bodied freshwater fish locally referred to as “kaka chekida,” was found in the Chalakkudy River. This species further contributes to the diversity of freshwater fish in the Western Ghats, a region already celebrated for its abundant and varied aquatic life. The detailed examination and description of these species highlight the presence of undocumented ichthyofauna in the region, reinforcing the Western Ghats’ reputation as a vital reservoir of biodiversity.
Resolution of a Centuries-Old Taxonomic Confusion
In addition to the discovery of these two species, the ICAR-NBFGR team successfully resolved a longstanding taxonomic issue that has persisted since 1870. Over the past 150 years, specimens now identified as Labeo uru and Labeo chekida were often misidentified as Labeo nigrescens, a species originally described in the 19th century. Using advanced morphological analysis, researchers were able to confirm that Labeo nigrescens is a distinct species, thereby clarifying a complex taxonomic puzzle that had confounded ichthyologists for generations.
This clarification of Labeo nigrescens’ identity, separate from the newly discovered species, represents a crucial advancement in the field of fish taxonomy. It eliminates a major source of confusion in species identification and paves the way for more accurate biological documentation and ecological studies.

ICAR-NBFGR Enhancing Understanding of Biodiversity and Conservation
The discovery of Labeo uru and Labeo chekida by ICAR-NBFGR, alongside the resolution of the historical taxonomic ambiguity surrounding Labeo nigrescens, underscores the critical importance of systematic exploration in biodiversity-rich regions such as the Western Ghats. Accurate identification of species is essential for the formulation of effective conservation strategies aimed at protecting fragile aquatic ecosystems.
The Western Ghats, designated as one of the world’s eight hottest hotspots of biological diversity, continue to reveal new aspects of their ecological wealth through meticulous scientific efforts. Documenting new species enhances scientific understanding of ecological interactions, evolutionary processes, and habitat requirements, all of which are fundamental to crafting informed conservation policies.
Ensuring the preservation of these newly discovered species is vital for maintaining ecological balance and protecting the rich natural heritage for future generations. The efforts of the ICAR-NBFGR researchers not only contribute to expanding the taxonomic database but also emphasize the necessity of ongoing scientific research and conservation initiatives in areas facing increasing environmental pressures.
The discovery of Labeo uru and Labeo chekida by ICAR-NBFGR thus represents a meaningful addition to the biodiversity records of the Western Ghats, while the clarification regarding Labeo nigrescens resolves a critical gap in ichthyological taxonomy, collectively reinforcing the imperative of sustained and detailed biological exploration.
