“…The Ponto-Caspian (P-C) region (Black Sea, Sea of Azov and Caspian Sea) remains an important donor region of many invasive species, including invasive gobiid fishes (Roche et al, 2013). Invasions of P-C gobies are now apparent across much of Europe (Wiesner, 2005, Naseka, 2005, Rizevsky et al, 2007, Antsulevich, 2007, Janáč et al, 2012, Konečná and Jurajda, 2012 and in North America (Dillon and Stepien, 2001;Kornis and Vander, 2010;Kocovsky et al, 2011). Invasive gobiids include the western tubenose goby Proterorhinus semilunaris and the monkey goby Neogobius fluviatilis.…”
