Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ?, range 11 - ? cm
Max length : 25.0 cm TL オス/雌雄の選別がない; (Ref. 5723); common length : 11.3 cm TL オス/雌雄の選別がない; (Ref. 12193); 最大記録サイズ: 9 年 (Ref. 12193)
Occurs in various habitats, but most common in rocky riffles and runs of clear mountain creeks and small to medium rivers. Rarely found in lakes (Ref. 1998). Feeds on diatoms, other algae, higher plants, dipterous larvae and pupae (Ref. 1998). Spawning adults may be preyed upon by birds and mammals while small individuals may be preyed upon by stream salmonids (Ref. 1998). Edible.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00316 - 0.01259), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
栄養段階 (Ref.
69278): 2.3 ±0.18 se; based on food items.
Generation time: 3.9 ( na - na) years. Estimated as median ln(3)/K based on 1
