| Over the past three decades, sturgeon populations in the Caspian Sea have significantly declined due to overfishing and inadequate sustainable management practices. This research aims to assess assessment of the restoration trend of Sturgeon stock by using SWOT model. The data was collected through questionnaires, which provided both quantitative and qualitative insights into various aspects of the phenomena. The findings were then generalized to identify the strengths, weaknesses, opportunities, and threats related to the restoration process of sturgeon stocks in these waters. The reliability of the questionnaire was confirmed using the internal consistency method (Cronbach's alpha), In this research, the Cronbach's alpha coefficient was 0.94, as well as the reliability of each of the strengths (0.89), weaknesses (0.83), opportunities (0.92) and threats (0.88). Key reasons for the decline in sturgeon stocks and catches include lack of effective management and sustainable exploitation of fish stocks, insufficient revival and protection measures for stocks, socio-economic issues, particularly unemployment in coastal communities, inadequate policy-making and investment in the fisheries sector, habitat destruction and obstruction of migration routes for spawning due to dam construction on major rivers, changes in food resources in spawning areas, and industrial pollution, urban, and agricultural activities. | ||
