Beschreibung

Tor is a genus of large cyprinid fish found in rivers and lakes across South Asia and Southeast Asia. They are renowned for their impressive size, powerful build, and migratory behavior. Often referred to as 'Mahseer,' which translates to 'Maha' (great) and 'seer' (fish) in Sanskrit, they are highly prized game fish and hold significant cultural and ecological importance. The genus includes several species, many of which are critically endangered due to habitat loss, pollution, and overfishing.

Barbels

Presence of two pairs of prominent barbels around the mouth is a key identifier for the genus Tor.

Scales

Large, cycloid scales are characteristic. The number of lateral line scales can help differentiate species.

Dorsal Fin Spine

The strong, often serrated, bony spine at the front of the dorsal fin is a distinguishing feature.

Body Shape and Size

Their robust, torpedo-shaped body and potential for very large size (up to 2.7 meters and over 50 kg in some species) are indicative.

Lebensraum

Wassertyp: freshwater
Tiefe: Typically found in shallow to moderately deep sections of rivers and streams, especially near rapids, pools, and rocky substrates. Juveniles may inhabit shallower tributaries.
Umgebung: Clear, fast-flowing rivers and streams with rocky or gravel bottoms. Also found in large, clear lakes connected to these river systems. They prefer well-oxygenated waters.
Geografische Verbreitung: South Asia and Southeast Asia, including the Himalayan foothills, India, Nepal, Bhutan, Bangladesh, Myanmar, Thailand, Malaysia, Indonesia, and parts of China.
