Biology     Glossary (e.g. epibenthic)

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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00433 - 0.01268), b=2.97 (2.82 - 3.12), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.62 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Very high vulnerability (79 of 100) .
Price category (Ref. 80766):   Very high.
