- Аннотация: The Caspian Sea basin, the world’s largestenclosed inland water body, faces escalatingthreats from non-native fish introductions. This systematic review provides a comprehensive overviewand updated inventory of totally 52 non-nativefishspecies (17 orders, 26 families, and 42 genera) within the basin. Cypriniformes and Gobiiformes dominate the assemblage. Primary introduction pathways are aquaculture (e.g., grass carp Ctenopharyngodon idella), ornamental releases (e.g., goldfish Carassius auratus), and canal-mediated dispersal (e.g., round goby Neogobius melanostomus). Successful invaders like Carassius gibelio and Gambusia holbrooki disrupt native ecosystems via competition, predation, and hybridization. Spatial analysis identifies the Volga (36.17%) and Southern Caspian (31.91%)sub-basins as introduction hotspots. Southeast Asia(26.92%, n = 14) and North America (13.46%, n = 7)are the primary biogeographic donor regions. Historical records show that both deliberate and accidental introductions have significantly altered trophic webs and endemic populations. Critical knowledge gaps persist for certain taxa (e.g., Carassius spp.). The synthesis was conducted following a systematic literature search, underscoring the urgent need for strengthenedbiosecurity, enhanced early detection, and coordinated transboundary management to counteract the negative effects and mitigate ongoing ecological and economic consequences, providing a critical, evidence-based foundation for conservation policy.
