Studies were conducted to explore the survival and growth potential of Tor macrolepis in existing polyculture system when cultured with Indian major carps viz, Labeo rohita (Rohu), Catla catla (Thaila) and Cirrhinus mrigala (Mrigal). There were two treatments and a Control, with three replicates each. Fish stocking density in all the treatments was kept 2000 fish/ha. Control contained only Tor macrolepis (100%); Treatment-1 (T1) stocked with Labeo rohita 60%, mrigal 25% and Catla catla15%; while Treatment- 2 (T2) with Tor macrolepis 20%, Labeo rohita 50%, Cirrhinus mrigala 20% and Catla catla10%. Fish was fed daily, @ 5% of its body weight and studies were continued for 120 days. Among treatments, Tor macrolepis gained slightly higher weight in T2 than Control; Labeo rohita gained significantly higher in T1 than T2; Cirrhinus mrigala gained slightly higher weight in T2 than T1 and Catla catla gained similar weight in both, T1 and T2. Overall Catla catla gained maximum weight while Tor macrolepis gained minimum. The survival rate and feed conversion ratio (FCR) of Tor macrolepis was significantly higher in T2 than Control. It is observed that Tor macrolepis has some food overlapping with Labeo rohita. Semi-intensive, polyculture, Mahseer, Rohu, Mrigal, Thaila, FCR, SGR Pakistan Agricultural Scientists Forum
