A Fish, Not a Bird
What the Golden Mahseer is
- The Golden Mahseer (Tor putitora) is a large freshwater fish.
- It lives in Himalayan rivers and is prized by anglers.
- It is Endangered on the IUCN Red List.
- Dams, pollution and overfishing threaten it.
- Sources: WWF-India and Wikipedia.
Not the other mahseer
- Indian Nightjar, Spoonbill and White Ibis are all birds.
- The Golden Mahseer is a different species from the Blue-finned Mahseer.
- The Golden Mahseer lives in Himalayan rivers, not the Cauvery.
True or False: The Golden Mahseer (Tor putitora) is a large freshwater fish, not a bird.
The Three Real Birds
Nightjar, spoonbill and ibis
- Indian Nightjar: a small night bird with camouflaged feathers and a churring call.
- Eurasian Spoonbill: a wading bird with a long, flat, spoon-shaped bill. It sweeps the bill through shallow water to catch fish and crustaceans.
- White Ibis: a wading bird of wetlands and coasts. Indian ibis species include the Black-headed (Oriental White) Ibis.
True or False: The Eurasian Spoonbill is identified by its long, flat, spoon-shaped bill.

- UPSC 2022Which of these is not a bird: Golden Mahseer, Indian Nightjar, Spoonbill or White Ibis? The answer is the Golden Mahseer, a fish. View the question.
True or False: In UPSC 2022’s question, the Golden Mahseer was the correct odd one out.
A Real Decline, and Real Conservation
How far it has fallen
- The IUCN estimates the population fell by over 50% in about 21 years, or three generations.
- Dams, changed river flows, barriers to migration and overfishing all contribute.
- It is a state fish of Uttarakhand, Himachal Pradesh, Arunachal Pradesh and Madhya Pradesh, and of the UT of Jammu and Kashmir.
- Sources: IUCN Red List assessment and Wikipedia.
Bringing it back
- Conservation uses hatchery breeding and ranching: stocking rivers with hatchery-bred young.
- WWF-India surveyed the Kosi River in Uttarakhand.
- It is preparing a species management plan for a 30-kilometre stretch.
- Source: WWF-India.
Think it through: why is hatchery stocking alone not enough to save the Golden Mahseer?
Stocking adds numbers but fixes nothing. Dams still block migration, flows stay altered and fishing continues. New fish face the same pressures that cut the wild population. Recovery needs habitat restoration and fishing controls as well.
True or False: IUCN estimates show the Golden Mahseer population fell by over 50% in 21 years.
True or False: WWF-India has worked on a species management plan for the Golden Mahseer on a stretch of the Kosi River.
True or False: The Golden Mahseer and the Blue-finned Mahseer are the same species, found in the same river.
