Catla (Catla catla), also known as the major (Indian) carp, is an economically important South Asian freshwater fish in the carp family Cyprinidae. It is commonly found in rivers and lakes in northern India, Nepal, Myanmar, Bangladesh, and Pakistan. In Assam, it is known as bahu, bhokua, or baudhekera.
Catla is a fish with large and broad head, a large protruding lower jaw, and upturned mouth. It has large, greyish scales on its dorsal side and whitish on its belly.
Catla is a surface and midwater feeder. Adults feed on zooplankton, but young ones on both zooplankton and phytoplankton. Catla attains sexual maturity at an average age of two years and an average weight of 2 kg.
The catla is the only member of its monotypic genus Catla, and is listed as Catla catla for instance in FishBase. Nevertheless Catalog of Fishes indicates Gibelion as the valid (senior) name of this genus.
It is one of the most important aquacultured freshwater species in South Asia. It is grown in polyculture ponds with other carp-like fishes, particularly with the roho labeo and mrigal carp. The reported production numbers have increased sharply during the 2000s, and were in 2012 about 2.8 million tonnes per year.
Catla is sold and consumed fresh, locally and regionally. It is transported on ice. Fish of 1–2 kg weight are preferred by the consumers.
