The '''rohu''', '''rui''', or '''roho labeo''' (''Labeo rohita'') is a species of fish of the [[Cyprinidae|carp family]], found in rivers in [[South Asia]]. It is a large [[omnivore]] and extensively used in [[aquaculture]].

==Description==
The rohu is a large, silver-colored fish of typical [[cyprinid]] shape, with a conspicuously arched head. Adults can reach a maximum weight of {{convert|45|kg|abbr=on}} and maximum length of {{convert|2|m|ft|abbr=on}},<ref name=fishbase/> but average around {{convert|1/2|m|ft|abbr=on}}.{{citation needed|date=March 2019}}

==Distribution and habitat==
The rohu occurs in rivers throughout much of northern and central and eastern [[India]],<ref name="agrifarming.in">{{cite web|url=http://www.agrifarming.in/rohu-fish-farming/|title=Rohu Fish Farming Information Guide - Agri Farming|date=26 August 2015|website=Agrifarming.in|access-date=8 September 2018}}</ref> [[Pakistan]], [[Vietnam]], [[Bangladesh]], [[Nepal]] and [[Myanmar]], and has been [[Introduced species|introduced]] into some of the rivers of Peninsular India and [[Sri Lanka]].<ref name=iucn/><ref name=fishbase>{{FishBase | genus = Labeo | species = rohita | month = May | year = 2013}}</ref>

==Ecology==
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.<ref>{{cite web|url=http://www.keralaagriculture.gov.in/htmle/bankableagriprojects/fish%5Cfishculture.htm |title=Composite fish culture |website=Kerelaagriculture.gov.in |access-date=2012-03-10}}</ref>

Rohu reach 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.<ref name="fishbase"/>

==Aquaculture==
The rohu is an important [[aquaculture]]d freshwater species in South Asia.<ref>{{cite web|url=http://www.fao.org/fishery/culturedspecies/Labeo_rohita/en|title=FAO Fisheries & Aquaculture Labeo rohita|website=Fao.org|access-date=8 September 2018}}</ref> When cultured, it does not breed in [[lake ecosystem]]s, so induced spawning is necessary.<ref>{{cite journal|url=http://www.nefisco.org/downloads/DevelopmentOfFreshwaterFishFarming.pdf|title=Development of freshwater fish farming and poverty alleviation - A case study from Bangladesh|last1=de Graaf|first1=G.|last2=Latif|first2=A.|year=2002|journal=Aquaculture Asia|volume=7|issue=2|page=5}}</ref><ref>{{Cite web|url=http://www.nickparkerllc.com/index_pdf/pubs/parker/33induced.htm|title=Induced spawning of Indian major carps through a single application of Ovaprim-C.|last=Nandeesha|first=M.C.|date=1990|publisher=Asian Fisheries Society|access-date=23 January 2017}}</ref> The rohu is also prized as a game fish.<ref name=iucn/>

==Preparation as food==

Rohu is very commonly eaten in [[Bangladesh]], [[Nepal]], [[Pakistan]] and the [[India]]n states of [[Tripura]], [[Nagaland]], [[Bihar]], [[Odisha]], [[Assam]], [[West Bengal]], [[Andhra Pradesh]], [[Tamilnadu]] and [[Uttar Pradesh]].<ref name="agrifarming.in"/>
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.<ref>{{cite book |author=K.T.
