Biologia     Glossario (es. epibenthic)

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. 115969): 7.5 - 25.5, mean 15.6 °C (based on 138 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00141 - 0.00709), 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).
Vulnerability (Ref. 59153):  Very high vulnerability (83 of 100) .
Price category (Ref. 80766):   Unknown.
