“…Two of these gobies from Black Sea Region of Turkey, Western tubenose goby Proterorhinus semilunaris (Heckel, 1837) and monkey goby Neogobius fluviatilis (Pallas, 1814), are an important component of the native fish communities of Turkish inland waters and locally marketed for food consumption (Özuluğ, Altın, & Meriç, 2005;Turan, Taş, Çilek, & Yılmaz, 2008;Çınar et al, 2013). Whilst they are usually included within ichthyofaunal studies (Geldiay & Balık, 1988), there is only limited knowledge on their biology, such as length-weight relationships (Tarkan, Gaygusuz, Özuluğ, Gürsoy Gaygusuz, & Saç, 2009), reproductive parameters (Sasi & Berber, 2010) and diurnal feeding preferences (Gaygusuz, Gürsoy Gaygusuz, Tarkan, Acıpınar, & Türer, 2007). They are also considered potential invaders in Europe and North America.…”
