AB To observe the survival and growth of golden mahseer (Tor macrolepis) and its impact on other traditionally cultured carps in pond polyculture, a study was conducted at Fisheries Research & Training Institute, Manawan, Lahore. Fish -1 fingerlings in equal densities, i.e. 2000 ha were stocked with two combinations (i.e. two treatments) in triplicate and fed with supplementary feed containing 25% crude protein @ 3% of live body weight. Fortnight weights, net weight gains (NWG), percentage weight gain (PWG), specific growth rate (SGR), gross and net fish productions/ha/year were calculated. Comparison through multivariate analysis of variance (MANOVA) showed that final weights of Labeo rohita, Catla catla and Ctenopharyngodon idella were significantly higher in T (P < 0.05) than in T , while of Cirrhinus 1 2 nd mrigala and Hypophthalmichthes molitrix did not varied statistically (P > 0.05). The inclusion of mahseer in 2 treatment did not affect the survival rate of experimental fish species. It can be concluded that endemic Indus mahseer can survive and grow under warm water polyculture, however it has significant negative effects on growth of Labeo rohita, Catla catla and if prolonged on Ctenopharyngodon idella and also on overall per unit fish production. dietary protein requirements, FCR and SGR (Islam et al,
