摘要：
The Ponto-Caspian round goby Neogobius melanostomus is a fish well known for its invasion success in North America and Europe. Though it originates from eastern Europe, it is only native to a few rivers in this region. Since the species is physiologically tolerant of varying environmental conditions, rapid spread and establishment to adjacent water basins is likely. Establishment of the species is also associated with ecological consequences. It is therefore important to track its spread close to the native region, which is often overshadowed by reports from further away. Here we report the first evidence of alien invasion in the Aegean watershed by N. melanostomus following a regional monitoring program of the fish fauna. Size- and sex-related characteristics of the population are discussed in relation to its level of establishment.
