Description synthétique Clés d'identification | Morphologie | Morphométrie

Distinguished from congeners in Europe by possessing two unique characters: 13-17 scutes on trunk, no scutes above anal base; and posterior edge of scutes smooth. Differs further by having scutes forming a lateral keel on caudal peduncle (Ref. 59043).

Adults inhabit springs. Mature individuals spawn in February - October (Ref. 59043). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00408 - 0.02689), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.2 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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