The rohu, rui, or roho labeo (Labeo rohita) is a species of fish of the carp family, found in rivers in South Asia. It is a large omnivore and extensively used in aquaculture.
The rohu is a large, silver-coloured fish of typical cyprinid shape, with a conspicuously arched head. Adults can reach a maximum weight of 45 kg (99 lb) and maximum length of 2 m (6.6 ft), but average around 1⁄2 m (1.6 ft).
The rohu occurs in rivers throughout much of northern and central and eastern India, Pakistan, Bangladesh, Nepal and Myanmar, and has been introduced into some of the rivers of Peninsular India and Sri Lanka.
