морской; пресноводный; солоноватоводный; анадромный (Ref. 51243). Subtropical; 44°N - 24°N, 96°W - 81°W
Western Central Atlantic: Gulf of Mexico (northern part, from the Mississippi delta eastward to the Choctawhatchee River in Florida; also in rivers from Iowa to Arkansas and across to West Virginia). Status of threat from Ref. 11858.
Size / Вес / Возраст
Maturity: Lm ?  range ? - ? cm
Max length : 51.0 cm SL самец/пол неопределен; (Ref. 188); common length : 42.5 cm SL самец/пол неопределен; (Ref. 188); наибольший возраст (опубликованны данные): 4 годы (Ref. 12193)
колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0. Body moderately compressed, belly with distinct keel of scutes. Lower jaw steeply rising within mouth; no teeth present at front of jaws; upper jaw with a distinct notch. The only other shad of the Gulf of Mexico has only 20 to 24 gill rakers. Closely resembles A. aestivalis and A. pseudoharengus of Atlantic coasts, but in them the lower jaw rises very steeply in the mouth (Ref. 188).
Forms schools. Ascends rivers and streams to spawn in spring or early summer, the young presumably descending in autumn. Marketed mostly fresh.
