. The introduction to aquaculture across India started in the early 1940s and in the 1950s and in the 1960s to other Asian countries.

The Indian carps are considered as a delicacy compared to other exotic carp species also cultured in Asia, and sell for higher prices. Reported annual aquafarming production numbers of mrigal carp since the early 1990s have varied between 250,000 and 550,000

Habitat and ecology

Mrigal is the benthopelagic and potamodromous plankton feeder. It inhabits fast flowing streams and rivers, but can tolerate high levels of salinity. Spawning occurs in marginal areas of the water bodies with a depth of over a sand or clay substrate. A female can lay a million eggs. This fish has a rapid growth rate; by the age of two individuals can reach a length of and can weigh as much as .
