Alosa macedonica spawn around the months of July and August. Apart from Lake Volvi, the species was previously present in Lake Koronia but in 1995 the lake dried up killing all the fish. Alosa macedonica Alosa macedonica, or the Macedonian shad (also known as "liparia"), is a landlocked species of clupeid 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 "Alosa" genus, whose other species are often anadromous migrating between marine and freshwater. Research suggests that the ancestors of "Alosa macedonica" inhabited
Herring juvenile herring could never catch a large copepod. Other pelagic prey eaten by herring includes fish eggs, larval snails, diatoms by herring larvae below , tintinnids by larvae below , molluscan larvae, menhaden larvae, krill, mysids, smaller fishes, pteropods, annelids, "Calanus" spp., Centropagidae, and "Meganyctiphanes norvegica". Herrings, along with Atlantic cod and sprat, are the most important commercial species to humans in the Baltic Sea. The analysis of the stomach contents of these fish indicate Atlantic cod is the top predator, preying on the herring and sprat. Sprat are competitive with herring for the same food resources. This is evident
