The feeding effects of Commercial dry food and barley on economic and production index in polyculture of common carp (Cyprinus carpio) in 2012 was evaluated. 1000 fish with an average weight of 11/22± 2/71g distributed in 9 ponds of 1 ha and feeded with 1: barley, treatment 2: 50-50 as barley- commercial dry food, treatment 3: Commercial dry foods were fed for a period of 8 months.
