Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale zachte stralen (totaal) : 12; Anale zachte stralen: 8. Distinguished by its color pattern: the bars in front of dorsal fin are conspicuously thinner than those behind, usually united in pairs (or more) at their upper extremity. This color pattern is shared with a few other species in area; S. poculi is distinguished from S. vinciguerrae by 8+7 branched caudal rays (versus 9+8), from S. mahnerti and S. bella by the absence of sexual dimorphism (both species have a well developed suborbital flap in males ) and by details of the color pattern (Ref. 39226).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Occurs in brooks and streams with swift current, among large pebbles, stones and boulders (Ref. 39226). Found in creeks and streams with moderate current and clear water (Ref. 43281). A 4.82 cm SL female contained nearly ripe ovulae, about 1.3 m diameter; when collected, a 5.22 cm SL female extruded yellow-orange ovulae; one of them still adheres to its genital opening (Ref. 39226).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00311 - 0.01538), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
