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.

Columbia River supports several species of anadromous fish that migrate between the Pacific Ocean and fresh water tributaries of the river. Sockeye salmon, Coho and Chinook (also known as "king") salmon, and steelhead, all of the genus "Oncorhynchus", are ocean fish that migrate up the rivers at the end of their life cycles to spawn. White sturgeon, which take 15 to 25 years to mature, typically migrate between the ocean and the upstream habitat several times during their lives. Salmon populations declined dramatically after the establishment of canneries in 1867. In 1879 it was reported that 545,450 salmon, with an average weight
