Max length : 51.0 cm SL jantan/; (Ref. 188); common length : 42.5 cm SL jantan/; (Ref. 188); Umur maksimum dilaporkan: 4 Tahun (Ref. 12193)
Duri punggung (Keseluruhan (total)) : 0; Duri dubur: 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.
Forms schools. Ascends rivers and streams to spawn in spring or early summer, the young presumably descending in autumn. Marketed mostly fresh.
