Özet

T & uuml;rkiye, a key biogeographic bridge between Europe and Asia, has experienced major advances in taxonomic knowledge of its freshwater fishes, but existing faunal lists lag behind recent revisions. We present a revised checklist that compiles and standardises records using the latest IUCN assessments, published descriptions and revisions (to 2026), museum collections and expert-verified data. Unestablished introductions and strictly marine visitors were excluded. We recognise 390 freshwater fish species in 37 families, including 367 native species and 23 established non-native taxa, of which 202 natives (55%) are endemic to T & uuml;rkiye. Species richness is concentrated in Leuciscidae (113 species), Nemacheilidae (59) and Cyprinidae (53), which together comprise 61.5% of the native fauna. At the catchment scale, total richness ranges from 11 species in the Van Basin to 65 in the Sakarya drainage, endemic richness was highest in Antalya (28 species) and non-native richness in the Sakarya drainage (10 species). The checklist provides updated nomenclature, distributions within T & uuml;rkiye and standardised common names, establishing an agreed taxonomic baseline for biodiversity assessment, fisheries and conservation management.
