Scientists from the Zoological Survey of India (ZSI) have unveiled an exciting discovery of three new species of hill stream loach fish from the Eastern and Western Ghats. These newly identified species, all belonging to the genus Indoreonectes, underscore the rich and diverse aquatic life in India’s wildlife sanctuaries.
The discoveries include:
- Indoreonectes amrabad: Found in the Amrabad Tiger Reserve, Eastern Ghats, Telangana.
- Indoreonectes kalsubai: Discovered in the Kalsubai Wildlife Sanctuary, Western Ghats, Maharashtra.
- Indoreonectes radhanagari: Located in the Radhanagari Wildlife Sanctuary, Western Ghats, Maharashtra.
Lead researcher Dr. Shrikant Jadhav explained that these fish species are unique due to their vibrant color patterns, including distinct lateral bands and head spots. Genetic analysis showed significant divergence from existing species, with variations ranging from 5.1% to 19.3%. This highlights their distinct evolutionary paths and the critical need to protect unexplored aquatic habitats across India.
With these findings, the total number of Indoreonectes species now stands at eight, with six from the Western Ghats and two from the Eastern Ghats. These fishes are characterized by rounded caudal fins, short lateral lines, and long nasal barbels, traits unique to the genus endemic to peninsular India.
ZSI director Dr. Dhriti Banerjee announced plans to establish a new Eastern Ghats Regional Centre in Amaravati to facilitate further biodiversity research and conservation efforts. These discoveries not only celebrate India’s natural heritage but also highlight the urgent need to protect fragile ecosystems in human-inhabited and protected regions alike.
