Europe: Adriatic Sea and its tributaries between Po (Italy) and Buna (Albania) drainages. Recorded from Corfu; present in lowermost part of Adriatic rivers from Soca to Drin. Records from Tyrrhenian slope of Italy, Spain and France are erroneous. In Appendix II of the Bern Convention (strictly protected fauna). International trade restricted (CITES II, since 1.4.98; CMS Appendix II). Only a single surviving naturally- spawning population at confluence of Ticino and Po; occasional records from Adriatic Sea and coastal rivers; spawning populations survived in Albania, but have possibly been extirpated. Status of threat: critically endangered.

Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 36-48; Raggi anali molli: 24 - 31. Snout moderate, very broad and rounded at tip. Lower lip continuous, interrupted at center. Barbels nearer to tip of snout than to mouth and not touching it. Five rows of scutes, dorsal 10-14 (the middle ones deeper and usually larger than those at front), lateral 32-42 on each side, ventral 8-11 on each side, with no smaller plates between dorsal and lateral rows. Back is olivaceous brown, flanks lighter, belly white.

Biologia     Glossario (es. epibenthic)

Occurs in the sea close to shore and estuaries, not entering pure marine waters. In freshwater, it inhabits large deep rivers (Ref. 59043). A long-lived species which is found mainly over sand and mud. Feeds on bottom-living invertebrates and small fishes. Reproduction takes place from May to July. Is threatened by habitat destruction, pollution and overfishing (Ref. 26100). The flesh is used for food but the eggs are not consumed as caviar (Ref. 6866).

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

Enters rivers from March to May, and presumably spawns then.

Estimates based on models

Preferred temperature (Ref. 115969): 14.7 - 18.2, mean 17.4 °C (based on 12 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):  3.4   ±0.50 se; based on food items.
Resilienza (Ref. 120179):  Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Very high vulnerability (86 of 100) .
Price category (Ref. 80766):   Unknown.
