Application of Super Efficiency Analysis Investigating the Performance of Cold-Water Fish Producers in Rainbow Trout Farming Fields of Isfahan Province

Due to economic importance production of fish farms, in this research, the producers of cold water fish rainbow trout farms in the province in 2017 was evaluated using Super efficiency comprehensive analysis. In this regard, the information required to complete the questionnaire and paddy yield method based on a comprehensive analysis of the results obtained were compared with Super efficiency comprehensive analysis. In general, the results showed that the average level of technical efficiency in the model with constant returns to scale assumption (CCR) equivalent 81.70% with a standard deviation of 0/258 in the range between 0.23 to 0.1 and only 3.23% on fish farms are efficient, but not much inefficiency in other units. The mean level of technical efficiency of variable returns to scale model (BCC), equivalent 15.92% SD 0.126 in the range between 0.55 to 0.1, and 60% were fully functional. The results indicate that the average efficiency of the scale is 85.31% and its range ranges from 0.36 to 0.1. As well as apparent differences in technical efficiency levels between the study areas are the most important cause of technical inefficiency in aquaculture has different way of managing. With regard to the results obtained with optimal management of inputs, the level of performance can be significantly increased.
