Short description Morfología | Morfometría

Espinas dorsales (total): 7; Radios blandos dorsales (total): 16-18; Espinas anales 1; Radios blandos anales: 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).

Biología     Glosario (por ej. 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).

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00632 - 0.01817), b=2.95 (2.80 - 3.10), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Nivel trófico (Ref. 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.
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (tmax=8; tm=3;).
