Rohu or roho labeo is a species of fish of the carp family, found in rivers in South Asia. It is an omnivore. It reaches a maximum length of 2 m (6.6 ft) and a weight of about 110 kg (240 lb). It may reach even greater weights in the northern part of Nepal.
During the early stages of its lifecycle, it eats mainly zooplankton, but as it grows, it eats more and more phytoplankton, and as a juvenile or adult is a herbivorous column feeder, eating mainly phytoplankton and submerged vegetation. It has modified, thin hair-like gill rakers, suggesting that it feeds by sieving the water[original research?].
It is diurnal and generally solitary. It reaches sexual maturity between two and five years. In nature, it spawns in the marginal areas of flooded rivers.
