Short description Morfologia | Morfometria

Spine dorsali (totale): 5 - 7; Raggi dorsali molli (totale): 15-16; Spine anali 0; Raggi anali molli: 11 - 13; Vertebre: 30. Differs from other species of Cottusin France by the combination of the following characters: in juveniles and adults, prickling on body extending backwards to caudal peduncle; no distinct transverse bands on pelvic; last dorsal-fin ray reaching rudimentary caudal-fin rays; eye diameter 27-31%; interorbital distance 1.9-2.4 times in eye diameter; last anal-fin ray connected to body by a membrane along about 2/3 of its length; depth of caudal peduncle 24-28% HL (Ref. 55856). Caudal fin with 13 to 16 rays (Ref. 40476).

Found in cold, karstic spring (Ref. 59043). Laboratory experiments, using natural photoperiod and constant temperature of 15-16°C corresponding with those of its habitat, showed that a female could lay eggs several times with less than one month interval. Between 20 to 70 eggs of relatively large size (2.1 mm) are laid (Ref. 30578).

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 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 (10 of 100).

Price category (Ref. 80766): Low.
