Eurasia: Western, northern and eastern Black Sea and Sea of Azov basins, from Bulgaria clock-wise to Kizilirmak drainage in northern-central Turkey (missing in Don); Aegean Sea basin, from Strma drainage eastward in Europe; northwestern Turkey. In lower reaches of rivers and coastal lakes, but in Dniepr up to Seim and Desna systems.

Max length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 556); common length : 18.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 556); 最大年龄: 8 年 (Ref. 59043)
背棘 (总数) : 3 - 4; 背的软条 (总数) : 8 - 10; 臀棘: 3 - 4; 臀鳍软条: 9 - 12; 脊椎骨: 36 - 38. Differs from Petroleuciscus smyrnaeus by having the following characters: dorsal fin with 8-9½ branched rays; ; anal fin with 9-10½ branched rays; iris orange to red; lateral line with 33-40 scales; posterior margin of anal convex or almost straight; without back pigments along free margin of each flank scale (Ref. 59043).
Adults inhabit lowland rivers, lower reaches of montane rivers, limans, lakes, deltas, backwaters with moderate to no current. They prefer to stay in warm water with temperatures up to 30-32° C, on sand, sand-mud or mud bottom, and in shallow places with slow current along banks, in backwaters, in small lakes and similar calm-water sites. Can tolerate slightly brackish water and low oxygen concentrations. Feed predominantly on insects and their larvae, but also takes plankton, benthic invertebrates and algae. Form spawning groups of up to 150 individuals. They do not undertake migration but move to deeper places in winter. Sharp decline of some populations is due to drainage of flood-plains and channelization of river beds (Ref. 59043).

Form spawning groups of up to 150 individuals (Ref. 59043). Asynchronous spawning, occurs two or three times in the season from the beginning of May to June (Ref. 74544). A hermaphrodite specimen was found, having a pair of testes and an ovary, the eggs being degenerated (Ref. 74544).欧亚大陆: 黑海; 进入多瑙河的黑海南方之内清空的保加利亚河; 罗马尼亚 (参考文献 12255) 与希腊;(参考文献 42629) 马尔马拉海。 黑海流域: 第聂伯河的下游; Yushnyi Bug; 中游 (基辅与进一步的向上游: Teterev 河, Seim 的流域) 与聂伯河的下游; 流入亚速海的河 Obitochnaya 与 Berda; 库邦河 (Talgir 系统) 的三角州; 外高加索西部。
