Biologia     Glossario (es. epibenthic)

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 Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

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=0.00468 (0.00239 - 0.00916), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.40 se; based on food items.
Generation time: 0.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (tmax=1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
