 family), found in North America, Europe, and the Mediterranean. The American shad, A. sapidissima, is one of the largest (6 lb/2.7 kg average) of the herrings and has delicious but bony flesh; its roe is valued as a delicacy. It is found along the Atlantic coast from Newfoundland to Florida and successfully introduced on the Pacific coast.Shad ascend rivers to spawn in the spring. Water pollution and overfishing have cut down their numbers. Named for its muscular gizzardlike stomach, the American gizzard shad, Dorosoma cepedianum, is a swift, silvery fish, 1 ft (30 cm) long, found along the Atlantic coast from New Jersey to Texas and up the Mississippi to the Great Lakes. Shads and gizzard shads are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Shad

 

(Alosa sapidissima), a fish of the family Clupeidae (herrings). The largest of the anadromous herrings, the shad is up to 75 cm long and weighs up to 6.4 kg. It is found along the Atlantic coast of North America, from the Gulf of St. Lawrence to Florida. It has been acclimatized in the Pacific Ocean, where it is found from Alaska to San Diego and near Kamchatka. The fish ascend rivers to spawn in the spring. The eggs are deposited in batches. Fecundity is up to 150,000 eggs. The diet consists of plankton (usually the larger forms) and, sometimes, fry. The shad is a valuable commercial fish. In recent years, the catch has decreased considerably because of pollution and the regulation of rivers.

Among the 16 species caught, five are amphihaline migratory species (Alosa alosa, Alosa fallax, Mugil cephalus, Petromyzon marinus, Anguilla anguilla) and 11 exclusively freshwater species, 10 of which have been introduced as part of water body replanting programs.
For further support, fecundity studies conducted on other species within the Alosa genus also demonstrated that no significant difference exists between fecundity estimates or oocyte diameter size calculated from samples taken from the middle, anterior, and posterior ends of the ovary (17, 18).
