A total of 18 G.sakaryaensis specimens was captured using electroshocker on October 18,2008 and February 5, 2009 from the Maşukiye Stream (western Lake Sapanca). Thisfinding has increased the number of the fish species living in the basin. Thevalue of parameter b in the LWRequation was calculated 3.176.The last comprehensive checklist of the freshwater fishes ofTurkey has reported that a total of 409 fish species inhabitin the freshwater systems and 194 of them is endemic to Anatolia (Çiçek et al., 2018). The genus, Gobio is known to beone of the richest genera because of its adaptations to different habitats (Turan et al., 2016). Recently, a total of 14 species belonging to the genus Gobio was recognised fromTurkish inland waters, and except Gobio bulgaricus and Gobio kovatschevi all of these species are the Anatolian endemics (Naseka et al., 2006; Kottelat and Freyhof, 2007; Turanet al., 2012; Turan et al., 2016; Turan et al., 2017; Turan etal., 2018). Gobio sakaryaensis is one of the endemic gudgeons and it was described from the Tozman and Porsukstreams in the Sakarya River drainage (northwestern Anatolia, Black Sea basin) (Turan et al., 2012).
