Biology

provided by Fishbase
Landlocked, lacustrine, pelagic, in upper water layers during summer and descending to deeper layers in winter. It spawns at 1-2 years, near shores above gravel or coarse sand, with most individuals spawning more than one season. Spawning starts when temperature reach about 19-20°C, in July to August (Ref. 59043). Adults form schools in the epilimnion during summer and tend to congregate in shallow waters near shores. They feed on plankton (cladocerans and copepods) and small fishes (Ref. 10545, 59043). It is threatened by water abstraction and pollution (Ref. 26100).

Alosa macedonica

provided by wikipedia EN

Alosa macedonica, or the Macedonian shad (also known as liparia), is a landlocked species of clupeid fish endemic to Greece.[1] Its single natural occurrence is the freshwater Lake Volvi in northern Greece. It is threatened by habitat loss.[1]

Biology

Alosa macedonica is a member of the genus Alosa, whose other species are often anadromous migrating between marine and freshwater.[2] Research suggests that the ancestors of Alosa macedonica inhabited marine regions of the Aegean Sea.[2]

Alosa macedonica have teeth in the palatine and vomer.[2] They have approximately 50 vertebrae and 106-128 gill rakers.[2] They are about 181-230mm in length and spawn around the months of July and August.[2]

Apart from Lake Volvi, the species was previously present in Lake Koronia but in 1995 the lake dried up killing all the fish.[1]
