Way of life
The Rohu is herbivorous . Young fish feed mainly on zooplankton , but in the course of their development they increasingly switch to phytoplankton . The phytoplankton is filtered using its gills. Adult fish also eat aquatic plants. The Rohu shows a diurnal lifestyle and lives mainly as a loner. After two to five years, the fish is sexually mature and, at the beginning of the monsoons, prefers to spawn on flood plains of rivers. The female lays 200,000 to 2 million fish eggs. In still water it does not reproduce naturally, so that reproduction has to be artificially induced in pond management.
Use
The rohu is a popular food fish that grows in pond farms v. a. held in Kerala and marketed as fresh fish. The Rohu has a non-oily white meat and is considered fried by the Oriyas and Bengali as a great delicacy and starter of the typical traditional diet.
