Researchers at the Centre for Peninsular Aquatic Genetic Resources, Kochi, have made a significant breakthrough in aquatic conservation. Working under the ICAR-National Bureau of Fish Genetic Resources (ICAR-NBFGR), Lucknow, the team developed the first-ever captive breeding protocol for the endangered black-collared yellow catfish (Horabagrus nigricollaris). This achievement marks the first comprehensive research on the species since its discovery in Kerala’s Chalakudy River in 1994.
The research, published in Aquaculture International, highlights the collaborative efforts to conserve this ecologically important species, which is listed as endangered on the IUCN Red List. Beginning in 2020, the scientists successfully bred a first-generation stock of the catfish, addressing the dual threats of habitat loss and overfishing.
Advanced fingerlings were later released into the Chalakudy River, and local fish farmers were engaged in breeding efforts to strengthen conservation and community livelihood.
Dr. U. K. Sarkar, Director of ICAR-NBFGR, praised the initiative, emphasizing the integration of advanced science with grassroots participation to safeguard biodiversity. The black-collared yellow catfish holds ecological significance and value in the ornamental fish trade, making its conservation critical for the Western Ghats' freshwater ecosystems.
This achievement underscores the importance of ex-situ conservation and paves the way for sustainable aquaculture practices.
It ensures not only the survival of H. nigricollaris but also contributes to preserving the rich aquatic diversity of India’s Western Ghats.
