Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 6 - 8; Rayons mous dorsaux (Total): 7-9; Épines anales 1; Rayons mous anaux: 8 - 9. This species is distinguished from its congeners by the following characters: upper part of caudal fin longer than the lower part; anterior extremity of anterior oculoscapular canal in front of middle of eye; no posterior oculoscapular canal; back unscaled in front of origin of second dorsal; breeding males with 4-8 dark bars when alive; total scales in midlateral series 33-40 (Ref. 59043).

Occur in shallow water, on sand and among weeds (Ref. 4696). Live less than 2 years. Feed on small benthic invertebrates (Ref. 59043). Spawn after first winter. Females may spawn several times during a season. Males defend eggs in cavities under stones, plant material or molluscs shells (Ref. 59043) like underside of lamellibranch valves (Cardium, Monodonta, Unio, etc.) (Ref. 4696). Eggs hatch at 3.0-3.8 mm (Ref. 59043).

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=0.00977 (0.00442 - 0.02163), b=3.05 (2.86 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (tmax < 2; tm < 1 (8-10 months);).

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