Understanding the Genus of Mahseer Fish

The question asks about the scientific genus to which the Mahseer fish belongs, which is recognized as the State fish of Madhya Pradesh.

The State fish of Madhya Pradesh is indeed known as the 'Mahseer'. Mahseer is a common name given to several species of large freshwater fish. These fish are native to South Asia and Southeast Asia. They belong to the family Cyprinidae, which is the carp family.

Specifically, the Mahseer species found in India and often referred to as the State fish belong predominantly to the genus Tor. While some related species might fall under the genus Neolissochilus, the term 'Mahseer' is most strongly associated with the genus Tor.

Let's consider the provided options:

• Pristis: This genus includes sawfish, which are cartilaginous fish (sharks and rays) found primarily in marine or brackish waters, not freshwater carp like Mahseer.
• Antigonia: This genus belongs to the boarfish family, which are small marine fish.
• Tinca: This genus contains the Tench, a different species of freshwater fish also in the carp family, but not the Mahseer.
• Tor: This is the correct genus that includes the well-known Mahseer species found in regions like Madhya Pradesh.

Based on scientific classification, the Mahseer, which is the State fish of Madhya Pradesh, belongs to the genus Tor.

Therefore, the correct answer is Tor.
