Kompowski A., 1998. Morphological features of the bleak Alburnus alburnus (L., 1758) from Międzyodrze. Acta Ichthyol. Piscat. 28 (2): 15-26.

17 meristic and morphometric features were studied in the bleak in the waters of Międzyodrze. Noticeable positive or negative allometry was observed in the growth of head length, horizontal eye diameter, pelvic fins length, body height, and in the distance between pelvic fins and anal fin. In the light of the studied features, the bleak in Międzyodrze places itself in a transitional position between the lake populations and the riverine and estuarine populations.
