Adults are found in the middle reaches of rivers during the summer; migrates downstream in autumn (Ref. 559). River bed consists of cobbles, boulders and gravel in riffles and sand and gravel in pools (Ref. 56353). Feed on fishes (Ref. 559). Juveniles migrate from the spawning ground in the sea to the middle reaches of rivers to grow (Ref. 56353).

From an aquarium observation, parental care is provided by the male which guarded and cared for the eggs until they hatch (Ref. 56353).

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=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.2 ±0.73 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Fec = 15,000).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100).

Price category (Ref. 80766): Low.
