Naziritor is a genus of large-bodied barbs in the mahseer group, a lineage of big-scaled cyprinid fishes found in the fast-flowing rivers and foothill streams of South Asia. The genus was split out from the true mahseers of Tor on anatomical grounds and is native to Pakistan, India, and Nepal. The atlas covers 2 species, Naziritor chelynoides (the dark mahseer) and N. zhobensis (the Zhobi mahseer), spanning a wide size range from roughly 12.5–26 in - substantial river fish built for holding position in strong current, with the deep body, large cycloid scales, and thick, fleshy lips typical of mahseer-type barbs.
Naziritor species are not aquarium staples; their large adult size and specialised riverine habitat requirements put them well outside typical home-tank keeping, and they are of far greater interest to river ecologists and, regionally, to anglers than to hobbyists. The conservation picture is mixed - one of the two species in the atlas carries a Vulnerable IUCN status, reflecting pressures common to South Asian river fish generally, such as damming, sand mining, and overfishing of mahseer-type species for food, while the other has not yet been formally assessed.
