Part 1: Common Fish Found in Bangalore Lakes

Karnataka is known to have the richest fish diversity in the country, there are about 240 species of fish found in Karnataka. A detailed list of all fish found in Karnataka can be found here and a list of fish found in Bangalore lakes can be found here (from line 725). Some of the most common fish found in Bangalore lakes are Rohu, Mrigal, Tilapia and Catla. Another common fish found is the African Catfish, an invasive species from Africa and the Middle East that has endangered many native species. 

Rohu is a common freshwater fish that belongs to the carp family. It is a native species of India and is found all over South Asia. The usual harvestable size of rohu is 1-1.5kg and is achieved within 12-18 months. This type of fish feeds from the middle level of the water. It is an extremely popular carp species as it is highly consumed. As it is the preferred fish for consumption it has made its way to become the most important cultivated fish in India. The market price for Rohu varies between Rs.120 to Rs.160 per kg.

Mrigal also known as Bngari in Kannada, is another important native carp fish species found in India. Like the Rohu, Mrigal is also widely aquafarmed. This is due to its rapid growth rate. Mrigal can weigh upto 2kgs and grow upto 60 cm within two years.  It mostly dwells at the bottom of the water. The Cauvery river is one of the few places the Mrigal can be found in the wild. The market price for this fish ranges between Rs.150- Rs.200 per kg.
