生態學
海洋; 淡水; 半鹹淡水; 溯河洄游 (Ref. 51243). 溫帶; 46°N - 25°N, 82°W - 66°W (Ref. 117467)
Western Atlantic: along the coast from Maine to the St. John's River, Florida, USA (Ref. 188). Possibly in Campobello Island, New New Brunswick, Canada (Ref. 86798).
西大西洋: 沿著海岸從緬因州到佛羅里達的聖約翰河。 也在河中。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 32.0 range ? - ? cm
Max length : 60.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188); common length : 34.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188)
背棘 (總數): 0; 背的軟條 (總數): 15-20; 臀棘 0; 臀鰭軟條: 19 - 23; 脊椎骨: 53 - 55. Belly with distinct keel of scutes. Lower jaw very prominent, but not rising steeply within mouth; teeth reduced or in upper jaw absent in fishes over 23 cm standard length. A dark spot on shoulder, several obscure dark spots along flank (sometimes missing). Closely resembles A. chrysochloris which has stronger jaw teeth, no shoulder spot and the body depth less than head length (Ref. 188). Silvery, with a dark grayish green back (Ref. 7251).
腹面有鱗甲的明顯龍骨脊。 下頜非常突出的, 但是不陡升在嘴裡面; 齒縮小的了或者在上頜中不存在於超過 23 公分標準長度的魚。 在肩上的一個深色斑點, 一些暗的深色斑點沿著側面.(有時不見的) 非常近似有較強壯的頜齒沒有肩斑點與體高少於頭長的 A. chrysochloris 。 (參考文獻 188) 銀色的, 具有一個黑的淺灰色的綠色背面.(參考文獻 7251)
In freshwater habitat, this species occurs in open water of large rivers (Ref. 86798). Schools of adults are found in marine waters, along the coast; also estuaries, tidal rivers and tributaries during late spring and early summer (Ref. 4639). Juveniles tend to leave nursery areas during summer (Ref. 4639). Feeds on small fishes, also squid, small crabs and other crustaceans, as well as fish eggs. Spawn in tidal freshwater (Patuxent River, Chesapeake Bay in May) (Ref. 188), and return to the sea shortly after (Ref. 4639). Parasites found are nematodes, cestodes and trematodes (Ref. 37032).
成魚的魚群被發現於海洋, 沿著海岸; 也在春末與初夏的時候河口，有潮汐漲落的河川與支流.(參考文獻 4639) 稚魚傾向休假繁殖場夏天時。 (參考文獻 4639) 捕食小魚，也捕食烏賊，小的螃蟹與其他的甲殼動物, 以及魚卵。 產卵於潮汐的淡水 (Patuxent 河, 切薩皮克海灣五月時)(參考文獻 188) 中, 而且回到海洋在.之後不久 (參考文獻 4639) 發現的寄生蟲是線蟲類，條蟲與吸蟲。 (參考文獻 37032)
