The exact numbers of humpback mahseer fish in the world are unknown. However, recently this fish has acquired the status of a Critically Endangered species in the IUCN Red List of Threatened Species and their population is steadily decreasing in the world.

Their numbers are decreasing because of dynamite fishing, dams being built on the Cauvery River, and from other ways that their habitats are being destroyed. The number of mature adults is still declining rapidly and their population is very fragmented.

Where does a humpback mahseer live?

The main river that the humpback mahseer is found in is the Cauvery River in the Western Ghats of India. They are also sometimes found in the Bhavani, Pambar, and Kabini river basins in Kerala.

They can mostly be found in the states of Karnataka, Kerala, and Tamil Nadu. Since they are endemic to such a small area of South India, they are very much affected by human activity and the loss of habitat due to human activities has pushed them to the brink of extinction.

What is a humpback mahseer's habitat?

The species is an Indian fish and is endemic to the Cauvery river basin and a few other smaller rivers in Kerala and the Western Ghats of southern India. These are freshwater fishes.

They seem to prefer deep stretches of fast-flowing and clear water. The adults also use the slow-flowing water for foraging, but they can also forage in fast-flowing waters. They also prefer rivers and streams that flow in upland areas.

Would they make a good pet?

The humpback mahseer fish, found in Tamil Nadu and other cities of India, is a pretty large species of fish. They are mostly used locally for eating purposes.

Unlike the koi fish who are a pretty small species of fish and are kept as pets, the humpback mahseer cannot be kept as pets. It is also bad for their conservation.

The reason for their rapid decline in population is mostly due to fishing. They should not be kept as pets as that might further hurt their ecosystem and lessen their numbers in the wild.

Did you know...

The humpback mahseer only got their scientific name Tor remadevii in 2018. Before extensive research was done on them, this fish species was thought to be the same as a Himalayan mahseer fish species called the golden mahseer, whose scientific name is Tor putitora. The previous scientific name of the species was Hypselobarbus mussullah.

Naming the humpback mahseer

The exact reason behind the naming of the humpback mahseer is not known other than the fact that they have a hump shape on their back. They are also called orange-finned mahseer because of the dark orange tint they have on their fins.

However, up until 2018, they were confused with the golden mahseer found in the Himalayan rivers and the species did not have a scientific name of its own.

In 2018, they finally got their scientific name Tor remadevii and were mentioned in the IUCN Red List. These fishes are also called the 'Tiger of the Cauvery'.

Is the humpback mahseer at risk of extinction?

Yes, unfortunately, this majestic fish and resident of Cauvery, humpback mahseer fish seem to be on the verge of extinction. They are already a Critically Endangered species in the wild according to the IUCN Red List of Threatened Species.

This is because of reckless fishing as this species is a game fish in India and is used locally for food purposes.

Their population has also decreased because of habitat loss due to human actions like building dams in rivers and dynamite fishing.

Fortunately, due to their IUCN status, some actions are being taken to ensure the conservation of the species. However, more things need to be done in the lines of captive breeding to ensure the survival of this species.
