Abstract: There is no recommended low cost feed available from fry to fingerling stage of Indian carps in Sri Lanka. Hence, this study was aimed on utilizing locally available aquatic plants Ipomea aquatica and Hydrilla vercillata and discarded dry fishmeal in feeds of Catla catla fry to cut down the feed cost. The experiment was conducted in a complete randomized design. Three experimental feeds were formulated using different protein sources while keeping other ingredients constant (T1= 1:1 discarded dried fish meal: Hydrilla vercillata, T2= 1:1 discarded dried fish meal: Ipomea aquatica, T3 = discarded dried fishmeal) and a commercial feed was used as the control. Catla catla fry were stocked at a density of 75 fry per m2 in 12 pond units. Fry were fed at the rate of 5% of the body weight.
