In present study, Analytical Hierarchy Process method was used fordeterminingmost important traits in the breeding program of Caspian Sea trout and two questionnaires were prepared in two stages. The first questionnaire was sent to the 43 Caspian Sea trout farms that were previously identified.In this questionnaire, farmers based on their knowledge and experience were asked to select and rank the six most preferred out of 15 economic traits that they should be included in genetic improvement of this species in the breeding objectives with the aim of making more profit on their aquaculture.In this phase, 26 completed questionnaires were received. Six selective traits for compiling second questionnaire were determined as: Thermal growth coefficient (TGC), Feed Conversion Ratio (FCR), Late maturation, Survival at harvest, Fillet percentage and Flesh color (redness). According to analytical instruction, 15 pairwise comparison questions were constructed which genetic parameters based on previous studies. The second questionnaire was sent to 26 farmers who had completed the first questionnaire.Finally, 21 farmers (81%)completed pairwise comparisons.The Analytical Hierarchy Process was used to estimate the vector of individual preference values and Inconsistency Ratio using Super Decisions software.A judgment is commonly reliable when Inconsistency Ratio is less than 0.10.After modification of the matrix of 19 observation that have Inconsistency Ratio
