Skipjack shad put into place in the northernmost reaches of its distribution. While the skipjack shad has been attributed to the subgenus "Potomolobius" of the genus "Alosa" along with other North American shad species, it has been found to be phylogenetically the most basal of the "Alosa" species, which are also found in Europe and Western Asia. Skipjack shad The skipjack shad ("Alosa chrysochloris") is a North American, migratory, fresh- and brackish water fish species in the herring family Clupeidae. The name skipjack shad comes from the fact that it is commonly seen leaping out of the water while feeding. Other common
Alosa lifespan of "Alosa" species can be up to 10 years, but this is generally uncommon, as many die after spawning. The systematics and distribution of "Alosa" shads are complex. The genus inhabits a wide range of habitats, and many taxa are migratory. A few forms are landlocked, including one from Killarney in Ireland, two from lakes in northern Italy, and two in Greece. Several species are native to the Black Sea and Caspian Sea. "Alosa" species of the Caspian are systemically characterized by the number of rakers on the first gill arch. They are classified as being "multirakered", "medium-rakered", or
