Researchers from the ICAR-National Bureau of Fish Genetic Resources (ICAR-NBFGR) have identified a new species of yellow catfish, Horabagrus obscurus, in the Chalakudy River, Kerala. Distinguished by its greenish-brown mottled appearance, shorter barbels, and unique genetic characteristics, this catfish shares its habitat with the endangered Horabagrus nigricollaris.
This discovery, published in the Indian Journal of Fisheries, highlights the rich biodiversity of the Western Ghats. Dr. U.K. Sarkar, Director of ICAR-NBFGR, hailed this breakthrough as a vital step toward conserving India’s aquatic genetic resources.
He emphasized the necessity of implementing conservation measures such as captive breeding and habitat restoration to ensure the survival of Horabagrus obscurus. “This effort is crucial for maintaining the ecological balance of the fragile ecosystems in the Western Ghats,” Dr. Sarkar stated.
The Western Ghats, a UNESCO World Heritage Site, cover just under 6% of India’s land area but are home to more than 30% of the country's flora and fauna. The region boasts incredible biodiversity, with 67% of its fish species and 50% of amphibians found nowhere else on Earth.
The discovery of Horabagrus obscurus not only highlights the ecological significance of the Western Ghats but also raises awareness about the urgent need for conservation. Habitat destruction, pollution, and overfishing pose significant threats to the region’s endemic species.
Researchers hope that this discovery will encourage further studies and collaborative efforts to protect India's aquatic treasures.
