Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 33 - 42; Spine anali: 0; Raggi anali molli: 18 - 24. Snout short, bluntly V-shaped, not upturned at tip. Barbels short (Ref. 7251). Absence of fontanelle and post dorsal shields. Single row of pre anal shields, 6-11 (Ref. 4639). Dorsal shields 7-13, lateral shields 22-34 (Ref. 4639). Blackish viscera (Ref. 37032). Head and back dark, lower surface white (Ref. 37032). Anal fin origin beneath dorsal fin origin (Ref. 86798).

Inhabit river mouths, lakes, estuaries, and bays; occasionally enters the open sea. Feeds mostly at night over soft substrates; juveniles feed primarily on benthic crustaceans and insects, adults prey on benthic crustaceans, insects and mollusks (Ref. 93252). Maximum known age is 67 years for females and 30 years for males. Flesh of good quality; eggs are suitable for caviar (Ref. 3192).

Estimates based on models

Preferred temperature (Ref. 123201): 7.5 - 25.5, mean 15.6 °C (based on 138 cells).

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

Bayesian length-weight: a=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.39 se; based on food items.

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (K=0.04; tm=14-17; tmax=67; Fec=48,000).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (86 of 100).

Price category (Ref. 80766): Unknown.
