Occurrence of the Non-Native Pumpkinseed Lepomis gibbosus in a Reservoir of the Karamenderes Basin (Çanakkale, Türkiye)

This study reports the recent discovery of the pumpkinseed Lepomis gibbosus in the Bayramiç Reservoir, which is located in the Karamenderes Basin (NW Türkiye). A total of five specimens were captured with a portable electrofishing unit. Total length (TL) and body weight (W) measurements were recorded with an accuracy of 0.1 cm and 0.01 g, respectively. The length and weight ranges of the specimens were 41–88 mm and 7.2–14.3 g, respectively. The presence of this non-native species in the study area could be attributed to either natural expansion or multiple (deliberate/indeliberate) introductions.
