生物學特性     字彙 (例如 epibenthic)

Occurs in standing or slow-flowing pools with a soft or rocky bottom. Thrives in dams and tolerates turbid waters. Juveniles occur in large shoals, adults in small groups. Feeds off the substrate on algae and detritus. Breeds in summer, moving into riffle areas to lay eggs (Ref. 7248).

出現於不動或者緩慢流動的水池具有一個柔軟或岩石的底部。 常見於水壩而且容忍混濁的水域。 稚魚出現在大群魚群，成魚在小群魚群。 在底部上啃食藻類與碎屑。 繁殖於被遷進急流沿岸區域到的夏天生下卵.(參考文獻 7248)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00226 - 0.01220), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  2.0   ±0.00 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (K=0.26; tm=1; tmax=3).
