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 species is an omnivore with specific food preferences at different life stages. 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.
Rohu reaches sexual maturity between two and five years of age. They generally spawn during the monsoon season, keeping to the middle of flooded rivers above tidal reach. The spawning season of rohu generally coincides with the southwest monsoon. Spawn may be collected from rivers and reared in tanks and lakes.
Preparation as food
Rohu is very commonly eaten in Bangladesh, Nepal, Pakistan, and the Indian states of Tripura, Nagaland, Bihar, Odisha, Assam, West Bengal, Andhra Pradesh, Tamilnadu, and Uttar Pradesh. A recipe for fried Rohu fish is mentioned in Manasollasa, a 12th-century Sanskrit encyclopedia compiled by Someshvara III, who ruled from present-day Karnataka. In this recipe, the fish is marinated in asafoetida and salt after being skinned. It is then dipped in turmeric mixed in water before being fried.
