Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 4; Dorsale zachte stralen (totaal) : 8 - 12; Anale stekels: 3; Anale zachte stralen: 5 - 8. Mouth is terminal and upturned. Normally has 12-14 vertical bars along the body, alternating with iridescent interbars of approximately equal width. Sympatric species have head scales or humeral spots and ocular bars.

Are generally cryptic or solitary (Ref. 58006). Inhabit heavily vegetated creeks, sloughs and roadside ditches. Feed on microcrustaceans and other small, benthic invertebrates (Ref. 58006). Oviparous, eggs are found in vegetation or just on the substrate (Ref. 58006).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.5 ±0.43 se; based on food items.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (tm=1; tmax=1.5; Fec=76).

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

Prijsklasse (Ref. 80766): Unknown.
