In this study, Recirculation Aquaculture Systems (RAS) of rainbow trout were analyzed and evaluated in Iran (Tehran). After analyzing these systems it was found which of them were better than others and then their parameters were used for designing a conceptual model of efficient RAS. This study was conducted in Iran (Tehran) in 2012 and statistical population and samples were 8 systems. Systems were analyzed and evaluated by five criteria which were as follows: economy, energy, consumption and recycling of water, technical and engineering and management. Analyzing and evaluating were conducted by Data Envelopment Analysis (DEA) method and also GAMS software was used for solving DEA model. It was found that in economy, energy, water consumption and recycling, technical and engineering and management criteria systems were efficient systems respectively. Based on the results, system 3 th with regard to all the criteria was efficient system. Quality and quantity factors and equipments of system 3 th were used in order to design a conceptual model of RAS in rainbow trout.
