Inhabits sand and gravel runs of small to large rivers (Ref. 5723, 86798). Feeds on aquatic insect larvae dominated by midges (Ref. 10294).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

The pelagic-broadcast spawning behavior consisted of males pursuing a single female and nudging her abdominal region. When the female was ready to spawn, a single male wrapped around the female at which time eggs and milt were simultaneously expelled. Reproduction usually consisted of several individual spawning episodes with at least 10-min intervals between events (Ref. 35784).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00247 - 0.00844), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.40 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (tmax=1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
