Comments: It is known from Atlantic coast from Maine to St. Johns River, Florisa (Ref. 86798). It is found in Chesapeake Bay and virtually all streams tributary to the Bay, Delaware River, and offshore waters of New Jersey (Ref. 4639). It has been Introduced into Virginia and New Carolina reservoirs and upper Tennesssee River system in Tennessee (Ref. 86798). Its range and abundance have been reduced due to dams (Ref. 86798). Also Ref. 188, 27549, 37512, 93252.

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 15 - 20; Spine anali: 0; Raggi anali molli: 15 - 21; Vertebre: 47 - 53. Moderately compressed, belly with distinct keel of scutes. Upper jaw with a distinct notch; lower jaw rising steeply within mouth; minute teeth present at front of jaws (disappearing with age). Lower gill rakers 41 to 52 (fewer in fishes under 10 cm standard length), slender. Back dark blue, sometimes bluish-grey; a dark spot on shoulder (Ref. 188). Peritoneum black (Ref. 7251). Branchiostegal rays 7 (Ref. 4639).

Inhabits rivers, estuaries, coastal waters, lakes and reservoirs (Ref. 117456). Adults are found in saltwater except during the spawning season and occur up to at least 200 km offshore (Ref. 117456). Forms schools and possibly wintering near the bottom and out from the coast, approaching the shore in the late spring. Feeds on small fishes, copepods and small shrimps. Spawns in brackish- or freshwaters of rivers, arriving in coastal waters a month or so later than A. pseudoharengus (in April at Chesapeake Bay, apparently when the water is above 7.0° C and later further north). Eggs are essentially pelagic, demersal in still water (Ref. 4639). Larvae are found in fresh and brackish rivers (Ref. 4639). Juveniles leave fresh and brackish nursery grounds at about 5 cm, migrating downstream (Ref. 4639). In freshwater habitat, this species usually occurs in current over rocky bottom (Ref. 86798). Marketed mostly fresh and salted (Ref. 188). Parasites found are acanthocephalan and nematodes (Ref. 37032).
