Maturity: Lm ? range ? - ? cm
Max length : 63.5 cm FL 雄鱼/尚未辨别雌雄; (Ref. 35835)
背棘 (总数) : 0; 背的软条 (总数) : 11 - 13; 臀棘: 0; 臀鳍软条: 8. Body depth 1 to 1.1 times in head length; ventral fin length less than 1.7 times in head length; nuchal hump starts gradually at occiput; silvery white.
体高 1 到 1.1 倍头长; 腹鳍长度少于 1.7 倍头长; 颈背的隆起逐渐地在后脑部开始; 银白色。
Occurs especially over muddy and sandy substrates all over the lake, preferably in water deeper than 6 m. A benthivore that at a larger size turns into a piscivore. Specimens smaller than 15 cm FL mainly eat insect larvae. Mollusks and plant material become more important with increased size. When fish reach sizes of 25 cm FL or more, fish are their main food.
生存尤其在泥泞多沙的底部之上在湖中各处, 可能地在深度超过 6 公尺的水域中。 一个在一个较大变成一个食鱼动物的底部觅食者。 比 15 公分 FL 小的标本主要地吃昆虫幼生。 软件动物与植物变得更重要的随着体型增大。 当鱼达到 25个公分 FL 或更多的大小的时候，鱼是他们的主要食物。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00422 - 0.02065), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.4 ±0.50 se; based on food items.
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
