The article addresses fishing challenges in the Small (Northern) Aral Sea, formed in 1989 following the Kokaral dams construction at the Berg Strait. The reduced water salinity has led to an expanded range of native commercial fish species. The ichthyofauna utilizes the entire Small Aral Sea for spawning and feeding, albeit unevenly across zones defined by salinity and biotopic features, a focus of this study. The primary sea biotopes are categorized as salty, brackish, and desalinated. Adapting fishing gear, seasonally and according to fish concentrations, is improved by factoring in salinity, depth, and feeding areas. Fish concentrations were studied via echo sounding and setting up fishing nets. Statistical analysis employed Surfer 20 and ArcGIS Online software, resulting in a map of fish concentration across the Small Aral Sea. A comprehensive strategy for optimal fish stock utilization, considering spatial and biotopic distribution, along with available fishing capacity, was formulated. Presently, the fishery employs only fixed nets, hindering efficient use of fish concentrations. A novel fishing area layout was proposed, accompanied by recommendations for fishing gear quantity in the Small Aral Seas fishing zones.
