Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά) : 7; Μαλακές ραχιαίες ακτίνες (συνολικά) : 14 - 18; Εδρικές άκανθες: 1; Μαλακές εδρικές ακτίνες: 12 - 17. This species is distinguished from its congeners entering freshwater in the Black Sea basin by the following characters: first branched ray of second dorsal about twice as long as penultimate ray; completely scaled nape; pelvic-disc fraenum with small rounded lobes and the length is less than 1/6 of width at base; pelvic disc reaching 90-100% of distance between its origin and anus; scales in midlateral series 55-61 + 2-4; posterior part of first dorsal without black spot (Ref. 59043).

Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Occurs in inshore habitats, estuaries and brackish- and fresh-water lagoons and lakes; large to medium sized rivers and streams; on sand or mud bottom. It is one of the most abundant fish in lowland rivers. This species lives up to 5 years; spawns for the first time at 2 years; spawning season in April to July, locally until September, when temperature is above 13°C; females may repeat spawning during a season. Males with body completely black with yellow fin margins during the spawning season; these excavate nests under any kind of hard substrate and guard eggs until hatching; with adhesive eggs deposited on stones, shells and aquatic plants. Feeds on a variety of invertebrates, especially molluscs (Ref.59043).
