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 as food in Europe, and early in the twentieth century their study was fundamental to evolution of fisheries science. These oily fish also have a long history as an important food fish, and are often salted, smoked, or pickled. Herring are very high in the long-chain Omega-3 fatty acids EPA and DHA. They are a source of vitamin D. Water pollution influences the amount of herring that may be safely consumed. For example, large Baltic herring slightly exceeds recommended limits with respect to PCB and dioxin, although some sources point out that cancer-reducing effect of omega-3 fatty acids is statistically stronger than
