**Chennai Man’s Passion for Native Fish Species Earns Him Scientific Recognition**

**CHENNAI, June 21, 2025** – Beta Mahatvaraj, a Chennai-based management professional, has turned his lifelong passion for documenting and protecting India’s native fish species into a significant contribution to the field of ichthyology.

For years, Mahatvaraj has dedicated his free time to exploring the Western Ghats and Northeast India, photographing, documenting, and sometimes rediscovering native fish species in their natural habitats. His fish room at his Anna Nagar residence houses meticulously maintained tanks showcasing species rarely seen in aquariums, like the Tambraparni Barb, Golden Cobra Snakehead, Denison Barb, and Canara Pearlspot.

Despite his successful career as a Chief Operating Officer (COO) at an agro-tech start-up, Mahatvaraj’s commitment to native fish conservation remains unwavering. He believes that these species are under threat from invasive species, destructive fishing practices, and pollution. Accompanied by fellow enthusiasts, he often embarks on weekend expeditions to remote areas, sometimes sacrificing meals to maximize daylight hours for snorkeling and observing the fish in their natural environment.

Mahatvaraj’s dedication has earned him the moniker ‘Meenkaran’ on his YouTube channel, where he shares his knowledge and passion for native fish. His expertise led to his contribution in the description of a new genus of fish from the Karnataka part of Western Ghats to a team of scientists from India and Sweden, which was named Betadevario ramachandrani in 2010 in his honor, while Ramachandran is another person who contributed to the study.

While writing a book about the native fish species, Mahatvaraj remains steadfast in keeping his passion separate from his profession. He emphasizes that his work at the agro-tech start-up fulfills his desire to help farmers, while his native fish exploration remains a legacy project fueled by passion rather than financial gain.
