生物学特性     字汇 (例如 epibenthic)

Inhabits rubble and gravel riffles of rivers and rocky lake shores. Individuals up to 5 cm feed on planktonic crustaceans and aquatic insect larvae especially that of midges and mayflies (Ref. 1998). Larger sculpins feed on minnows and other fishes (Ref. 1998). Possibly spawns in June (Ref. 1998).

栖息于河与岩石的湖岸瓦砾与碎石激流。 个体向上到 5 公分吃浮游性甲壳动物与水生的昆虫幼生特别是蚊与孚游类。 (参考文献 1998) 较大的杜父鱼科的河鱼吃条鱼类与其他的鱼。 (参考文献 1998) 在六月可能地产卵。 (参考文献 1998)

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.4   ±0.45 se; based on food items.
回复力 (Ref. 120179):  中等的, 族群倍增时间最少 1.4 - 4.4年 (Fec=448).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
