Descrição breve

Espinhos dorsais (total): 0; Raios dorsais moles (total): 15-19; Espinhos anais 0; Raios anais moles: 18 - 24; Vértebras: 51 - 60. Moderately compressed, belly with a distinct keel. Lower jaw not rising steeply within mouth. Gill rakers long and slender (fewer in young). Silvery in color with blue or blue-green metallic luster on back (Ref. 1998). A dark spot on shoulder, sometimes followed by several more, or even a second row. Resembles A. pseudoharengus with lower jaw rising steeply within mouth, eyes larger, and fewer lower gill rakers, as also A. aestivalis and A. mediocris (Ref. 188). Silvery, with a green or bluish back (Ref. 7251). Branchiostegal rays 7 (Ref. 4639).

Spend most of its life at sea, returning to freshwater streams to breed (Ref. 27547). Non-spawning adults are found in schools near the surface of continental shelf waters in spring, summer and fall (Ref. 7135); also found in brackish waters (Ref. 4607). Newly hatched larvae are found in rivers during the summer; by autumn they enter the sea and remain there until maturity. Juveniles form schools at 20-30 mm TL and gradually move downstream (Ref. 4639). Feed on plankton, mainly copepods and mysids, occasionally on small fishes. Feeding ceases during upstream spawning migration and resumes during the downstream post-spawning migration (Ref. 1998). Commercially caught in rivers and estuaries during spawning migration (Ref. 1998). Utilized fresh, salted, or smoked. The roe is esteemed. Eaten pan-fried, broiled, and baked (Ref. 9988). Possibly to 375 m depth (Ref. 6793). Parasites found are nematodes, Acanthocephala, copepods and distomes (Ref. 37032).
