Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 16 - 18; Spine anali: 1; Raggi anali molli: 12 - 16. This species is distinguished from its congeners in freshwaters in Black Sea basin by the following characters: papillae in suborbital area 8-10 vertical rows; total scales in midlateral series 72-85; naked nape (Ref. 59043).
Body shape (shape guide): fusiform / normal.

Biologia     Glossario (es. epibenthic)

Inhabits inshore, estuaries, brackish- and fresh-water lagoons on sand or rock bottom. Rarely occurs in pure freshwater (Ref. 59043). Found on sand, shell, and rocks near cliffs; at 20-60 m in summer, sometimes as deep as 100 m. Feeds mainly on fish (Ref. 4696). Approaches the sea coasts for spawning in spring (Ref. 2058). Due to large their large size, have certain commercial value in some areas and are popular for sport fishers (Ref. 92840).

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00632 - 0.01817), b=2.94 (2.79 - 3.09), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  4.2   ±0.73 se; based on food items.
Generation time: 4.4 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilienza (Fonte Biblio. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (tmax=8; tm=3;).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100). 🛈
Nutrients (Ref. 124155):  Calcium = 42.9 [25.9, 101.7] mg/100g; Iron = 0.405 [0.209, 0.760] mg/100g; Protein = 18.6 [16.7, 20.2] %; Omega3 = 0.688 [0.324, 1.287] g/100g; Selenium = 10.6 [5.0, 23.0] μg/100g; VitaminA = 22.5 [6.8, 73.4] μg/100g; Zinc = 0.557 [0.392, 0.816] mg/100g (wet weight);
