簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 10 - 17; 臀棘: 0; 臀鰭軟條: 16 - 22; 脊椎骨: 41 - 45. Silvery-white with black melanophores surrounding each scale on the dorsal two-thirds of the body. The dorsal half of the body is almost translucent.
銀白色有在背部上圍住每個鱗片身體中的三分之二的黑色的黑色素細胞。 背部一半的身體幾乎半透明。
Usually occur in large schools near surface in open water, over dark sandy bottom (Ref. 35360). Well adapted to a life of heavy predation (Ref. 35360). Frequent skipping over the water surface is observed apparently in avoidance of predators (Ref. 35360).
通常大群出現近表面的在開放的水域中, 在深色的沙質底部之上.(參考文獻 35360) 對重掠食的生活適應良好.(參考文獻 35360) 在水面上的時常跳越在掠食者的逃避中被顯然地觀察。 (參考文獻 35360)

Based on otolith data, these species spawn after their first winter and that only a small segment of the population lives through the second winter (Ref. 35360).北美洲: 出現在美國北卡羅萊那州只在湖 Waccamaw 中。

50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.

營養階層 (Ref.
69278): 3.1 ±0.41 se; based on food items.
Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回復力 (Ref.
