Short description Morfologia | Morfometria

Spine dorsali (totale): 24 - 26; Raggi dorsali molli (totale): 89-103; Raggi anali molli: 80 - 93; Vertebre: 86 - 90. Diagnosis: head relatively long, 15.7-21.1% SL (mean 18.2%), decreasing with size; origin of first dorsal spine situated before posterior edge of pectoral fin, (-9.5)-(-0.5)% SL [mean (-6.3%)]; body relatively deep, 7.8-9.6% SL (mean 8.7%); distance from tip of snout to last externally visible dorsal spine 49.0-56.2% SL (mean 52.1%), decreasing with size; origin of soft dorsal fin clearly anterior to origin of soft anal fin; lower jaw length 21.3-26.9% HL (mean 23.9%), increasing with size; distance from gill opening to dorsal pectoral fin base relatively short, 4.3-9.6% HL (mean 6.9%); 23+1 to 25+1 (median 25+1) dorsal spines (Ref. 81678).

Occurs in slow streams with a sandy bottom (Ref. 6060). Maximum reported total length 252 mm (Ref. 81678).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00257 (0.00122 - 0.00544), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).

Price category (Ref. 80766): Unknown.
