Rohu or roho labeo (Labeo rohita, Bihar - रोहू मछली, Oriya - ରୋହୀ,)(Urdu - رہو)is a species of fish of the carp family, found in rivers in South Asia.[1] It is an omnivore.[2]

It is called rahu in Nepali. In Hindi it is called rehu (rawas is the Indian Salmon, which is quite different). It is called rohi in Oriya, rui in Bengali,rehu in Maithili, rou in Assamese and Sylheti, rohu itself in Malayalam,[citation needed] and is reared in Kerala. It is popular in Thailand, Bangladesh, northern India and Pakistan. It is a non-oily/white fish.

It reaches a maximum length of 2 m (6.6 ft) and a weight of about 110 kg (240 lb).[3]

Biology[edit]

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.

It is the main diet of people of Bengal.[citation needed]

Aquaculture[edit]

It is an important aquacultured freshwater species in South Asia.[4] When cultured, it does not breed in lentic environments, so induced spawning becomes necessary.

Preparation as food[edit]

It is very commonly eaten in Bangladesh, Nepal and the Indian states of Bihar, Odisha, Assam, West Bengal and Uttar Pradesh.[citation needed] The Maithil Brahmins and the Kayastha community of Bihar and Uttar Pradesh treats it as one of their most sacred foods: to be eaten on all auspicious occasions.[citation needed] Rohu is common food in Pakistan and is usually eaten deep fried, or in a sauce with spices.

Rohu is also served deep fried in mustard oil, as kalia which is a rich gravy made of concoction of spices and deeply browned onions and tok, where the fish is cooked in a tangy sauce made of tamarind and mustard.
