The effect of using some commercial diets, manure and some agriculture by-products on performance of common carp. Cyprinus carpio, in polyculture system with tilapia, Oreochromis niloticus, has been investigated. The water quality measurements seemed to be within the normal range of tolerance and wellbeing of tilapia and common cap fishes. The performance results of common carp in terms of live body weight (LBW), body weight gain (BWG), specific growth rate (SGR), and condition factor (K) showed that the commercial diets exhibited superior performance rather these either treated with manure or agriculture by-products compost. Fish fed on the pelleted diet (24%CP) exhibited superior growth response rather than these fed on the mash diet containing (25% CP). The cow manure and chicken manure treatments gave significantly (P<0.05) higher growth performance than that of agriculture by-products and rice straw compost. From these results, it could be recommend to use diet for feeding common carp fish in earthen  ponds as pelleted  not as mash form and it is potential to use manure and agriculture by-product to fed common carp fish.
