Macedonian Moranec

Pachychilon macedonium is distinguished from P. pictum by the possession of the thick black stripe running along the sides from the tip of the snout to the base of the caudal fin, separating the dark brown back from the silvery belly. There is an ellipsoid black blotch on the caudal peduncle. These markings are clearer in preserved specimens. The lateral line has between 35 and 39 scales and there are 8+1⁄2 branched rays in the anal fin. This species has a maximum standard length of 12 cm (4.7 in).

Pachychilon macedonium is found in river systems draining into the northwestern Aegean Sea from the Pineios in Thessaly to the Gallikos in Central Macedonia, including lakes such as Doiran, Vegoritida, Petron and Chimaditida. In the Vardar the Macedonian roach extends into North Macedonia. There is an apparently introduced population in a stream draining into Lake Koroneia, close to the Gallikos. This is a shoaling species of lowland rivers, freshwater lakes and marshes, and it has become established in some reservoirs and canal systems.
