Editing Round goby (section)

==Distribution and habitat==
Round gobies are widespread in the [[Sea of Marmara]] and in the rivers of its basin and can also be found in the Black Sea and the [[Sea of Azov]], along all coasts and [[fresh water]]s of their basins as well as in the coastal [[lake]]s and [[lagoons]].  They are also found in the rivers of [[Crimea]] and the [[Caucasus]] ([[Mezib]], [[Pshada]], [[Vulan]], [[Kodori River|Kodori]], and [[Çoruh River|Çoruh]]) and in the Caspian Sea, represented by [[subspecies]] ''Neogobius melanostomus affinis''.

Since 1990, the round goby has been registered as [[invasive species|introduced]] in the North American Great Lakes, in parts of Europe, and in the Baltic Sea as an invasive species.<ref>{{cite journal|author1=Jude D.J. |author2=Reider R.H. |author3=Smith G.R. |year=1992|title= Establishment of Gobiidae in the Great Lakes basin|journal= Can.

Round gobies are [[euryhaline]] (salt-tolerant) and live in both freshwater and marine ecosystems, up to a mineralization of 18–24%. They are commonly found on [[continental shelf|continental shelves]] with sandy and rocky bottoms with low silting at depths from {{Convert|1–2|m|ft|abbr=on}} to {{Convert|10–17|m|ft|abbr=on}}.
