Alburnoides ohridanus

The Ohrid spirlin (Alburnoides ohridanus) is a fish species of family Cyprinidae. This species is endemic to Lake Ohrid in North Macedonia and Albania in the Balkans. It is a benthopelagic temperate freshwater fish, up to 9 cm in length. It was originally named as a subspecies of Alburnoides bipunctatus. It is threatened by non-indigenous species of fish, many of which have been introduced into Lake Ohrid.

It grows to 9 cm in standard length and can be distinguished from other Balkan species of Alburnoides by having a distinctly upturned mouth, the eye diameter being equal to the length of the snout, a distinct indentation on the nape, a long caudal peduncle which is just under twice as long as it is deep, 42-44 scales on the lateral line and in having 11$1⁄2$ branched rays in its anal fin. It occurs in the surf zone along the lake shore. It spawns in late spring, in May and June.
