- Blue Finned Mahseer is a freshwater fish. It is also known as Deccan Mahseer or Tor Khudree.
- It is one of the sub-species of Mahseer.
- IUCN Status: Least Concern (LC)
- It is a silvery-bluish coloured fish with blood-red fins or fins tipped with a bluish tinge.
- Indicator species: Blue finned Mahseer is very sensitive to dissolved oxygen levels, water temperature and sudden climatic changes. It just cannot bear pollution.
- Hence, it acts as an indicator of ecosystem health because its prime requirement is a clean and pure environment.
- Diet: The fish feeds on plants, fruits, insects, shrimps and molluscs and may be grown in ponds. They are also predatory and prey on smaller mahseer.
- Habitat: Blue Finned Mahseer is found in the Mula-Mutha River close to the Indian city of Pune, a part of the Krishna River basin. It is also found in other rivers of the Deccan Plateau.

Conservation Initiative by Tata power:
- Tata Group is involved in the conservation of the blue-finned and golden mahseer for 50 years in an Artificial Lake at the Walvan Hatchery in Lonavala (near Pune), Maharashtra.
- The company created a huge lake by damming the Indrayani River. It is at this artificial lake where Blue-Finned and Golden species of Mahseer congregate. Once the eggs hatch, they remain in the lake for 4-6 months.
- They are then handed over to various fisheries departments across the country, who in turn introduce them to lakes and rivers in their states.
- Hence, due to these initiatives, Blue Finned Mahseer has now been moved to the ‘least concern’ status. However, the golden mahseer is still in danger of going extinct.
