生物学特性     字汇 (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).

出现于不动或者缓慢流动的水池具有一个柔软或岩石的底部。 常见于水坝而且容忍浑浊的水域。 稚鱼出现在大群鱼群，成鱼在小群鱼群。 在底部上啃食藻类与碎屑。 繁殖于被迁进急流沿岸区域到的夏天生下卵.(参考文献 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).
营养阶层 (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.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (K=0.26; tm=1; tmax=3).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100).
价格分类 (Ref. 80766):   Unknown.
