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.

Estimates based on models

Preferred temperature (Ref. 123201): 1.6 - 9, mean 6.1 °C (based on 30 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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).

Trophic level (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.

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (79 of 100).

Price category (Ref. 80766): Very high.
