Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 7; Mjukstrålar i ryggfenan (totalt): 16-18; Taggstrålar i analfenan 1; Mjukstrålar i analfenan: 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).

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).
