Aquaculture, as one of the major industries, plays a crucial role in providing food and economic resources in many countries. To enhance competitiveness in this sector, traditional and commonly used multi-criteria decision-making methods are no longer sufficient, and it is necessary to utilize innovative hybrid approaches. This study presents a new hybrid method based on two-level SWOT analysis and the EDAS and VIKOR techniques for selecting the optimal species and scenario in the field of aquaculture. This research can support decision-makers in more accurately eva‎luating opportunities, threats, strengths, and weaknesses, thereby enabling the selection of the most suitable options and solutions for the sustainable development of the industry. This study focuses on multi-criteria decision-making processes and innovative methods such as two-level SWOT and fuzzy eva‎luation using EDAS and VIKOR to select the appropriate aquaculture species and scenario in the downstream lands of the Agh Chay Dam, located in Chaypareh County, West Azerbaijan Province. To identify the appropriate aquaculture species (Phase I) and the optimal aquaculture scenario (Phase II), the EDAS and VIKOR methods were integrated, resulting in the development of the novel EDKOR method. In this method, the calculation of positive and negative distances from the average is based on EDAS, while the determination of the group utility range and individual regret is based on VIKOR. Additional innovations of this research include the integration of decision-making methods, the application of two-level SWOT analysis, and the combination of SWOT with MADM for selecting the most suitable species and aquaculture scenario. The findings of the first phase indicate that the key criteria include the dependence of water quality and quantity on the selected species, access to national and international markets, and support from government organizations and decision-makers. In a group utility of 0.6, the prioritization of species is as follows: Trout, ornamental fish, sturgeon, warm-water fish, other native fishes, and tilapia.The results of the second phase also showed that the most important criteria include focusing on high-consumption products and polluting a smaller volume of water. With a group utility of 0.7, reproduction and production of fry up to 20 grams Fish was selected as the best scenario.
