Usually inhabits lower and middle reaches of rivers and lakes. A sea-run form is found in the eastern coast of Hokkaido. Young feed mainly on aquatic insects while fishes more than 30 cm are completely piscivorous. Spawns in spring in river branches, where the female lays 2,000-10,000 eggs on sandy or gravelly bottom.
通常居住于河川与湖泊的下游与中游范围。 一个海洋回游的形式被发现于北海道的东岸。 幼鱼主要吃水生昆虫然而鱼超过 30 公分完全以鱼为食。 在河分支中产卵在春天, 在哪里母鱼将 2,000-10,000个卵放在沙或多碎石的底部上。

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00437 - 0.01257), b=2.97 (2.82 - 3.12), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
营养阶层 (Ref.
69278): 4.5 ±0.5 se; based on diet studies.
Generation time: 22.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回复力 (Ref.
