Range extension of the invasive freshwater fish species, gibel carp Carassius gibelio (Bloch, 1782) in western Turkey

摘要

Gibel carp Carassius gibelio (Bloch, 1782) has become an important non-native fish in all regions of Turkish inland waters with its widedistribution, high prevalence and impacts on native fish species through mainly reproductive and feeding interactions. This paper presents thefirst record of gibel carp caught on 15 December 2011 from Tersakan Stream in Mu?la Province in SW Turkey. Size range of the species,possible introduction pathways and structure of the stream suggest that the species could well fit in its new environments and that furtherspread is likely.
