The Goksu River estuary at the Mediterranean coast is among the major estuarine systems in Turkey. The aims of the present study were to analyse the distribution and qualitative and quantitative composition of the ichthyofauna in the Goksu River estuarine zone. Fish were sampled by different nets at four sites from November 2014 till June 2017. A total of 47 fish species were identified in the coastal marine zone and 32 species belonging to 16 families in the river estuary. Chelon auratus, Chelon saliens and Mugil cephalus were the dominant species and comprised over 75% of the total catch number. Marine fish dominated by species richness and abundance. Five alien species (Carassius gibelio, Gambusia holbrooki, Chelon carinatus, Oreochromis niloticus and Sillago suezensis) were caught in the estuary. Of them, Gambusia holbrooki had the highest abundance (77.6%). The indexes of species richness, diversity and evenness exhibited a strong spatial and temporal variation throughout the study period.
