Alosa macedonica, or the Macedonian shad (also known as liparia), is a landlocked species of alosid fish endemic to Greece. Its single natural occurrence is the freshwater Lake Volvi in northern Greece. It is threatened by habitat loss.
Alosa macedonica is a member of the genus Alosa, whose other species are often anadromous migrating between marine and freshwater.[1] Research suggests that the ancestors of Alosa macedonica inhabited marine regions of the Aegean Sea.[1]
Alosa macedonica have teeth in the palatine and vomer.[1] They have approximately 50 vertebrae and 106-128 gill rakers.[1] They are about 181-230mm in length and spawn around the months of July and August.[1]
Apart from Lake Volvi, the species was previously present in Lake Koronia but in 1995 the lake dried up killing all the fish.
