Mrigal fish are the benthopelagic and potamodromous plankton feeder. Naturally they are mainly feed on detritus such as debris found in the bottom layers of the water. They are also a keen algae and invertebrates feeder. But today they are feed commercial feeds in commercial production.
Hatchlings of Mrigal generally remain in the surface or sub-surface waters. But the fry and fingerling tend to move to deeper water. And the mature fish are bottom dwellers. Depending on location, Mrigal fish generally reach maturity within their 1-2 years of age, when their body length reach around 34 cm. In natural conditions, generally breeding occurs during the south-west monsoon season in shallow newly inundated wetlands and or river side pools. They generally breed in water of 0.5-1.0 m. The females can lay up to a million eggs. Artificial breeding is very popular for this fish species.
