Environment: milieu / climate zone / depth range / distribution range
Ecologia
; acqua dolce benthopelagico. Tropical
Africa: many coastal basins of West Africa, from the Konkouré River in Guinea to the west of the Volta (Ref. 2940, 81282).
Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 24.5 cm SL maschio/sesso non determinato; (Ref. 83624)
Raggi dorsali molli (totale) : 13 - 16; Raggi anali molli: 8. Diagnosis: last simple ray partly ossified at base (no strong spine) and distinctly longer than head; lower reduced, substituted by horny sheath; 9-12 (usually 10) dorsal fin branched rays; scale formula 3.5-4.5/23-29/3.5-4.5; 2 scales between lateral line and pelvic-fin base; 12 scales around caudal peduncle (Ref. 2940, 81282).
Barbus wurtzi has differences in meristic and morphometric characteristics depending on which population; body depth varies between 26-33% in Guinean rivers and 34-43% in the Cavally and Nipoué rivers; the caudal peduncle length-height ratio is approximately 100% in Cavally-Nipoue and reaches an average of 140% in Guinean rivers; population east of Ivory Coast has intermediary characteristics such as number of scales above and below the lateral line: 4.5 in Guinea and Ivory Coast, 3.5 in western part of Ivory Coast and east of Liberia (Ref. 2940). Maximum TL was recorded at 27.5 cm (Ref. 2801).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00448 - 0.01616), b=2.97 (2.81 - 3.13), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
