Ecologia
marino; acqua dolce; salmastro pelagic-neritic; anadromo (Ref. 138280). 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.
Dimensione / Peso / Età
Maturità: Lm ? range ? - ? cm
Max length : 51.0 cm SL maschio/sesso non determinato; (Ref. 188); common length : 42.5 cm SL maschio/sesso non determinato; (Ref. 188); Età massima riportata: 4 anni (Ref. 12193)
Spine dorsali (totale) : 0; Spine anali: 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).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Adults form schools. They ascend rivers and streams to spawn in spring or early summer, the young presumably descending in autumn. Marketed mostly fresh.
