生態學
; 淡水; 半鹹淡水 底中水層性. 溫帶; 4°C - 20°C (Ref. 2059); 50°N - 43°N, 26°E - 52°E
Europe and Asia: Danube delta (Braila, Lake Brates); Lakes Kagul, Yalpukh, Katlabukh, Kitai. Dniester from the liman to the region of Kamentes-Podol'sk. Dnieper to Dnepropetrovsk; Odessa and all coasts of the Caspian Sea; and Volga at Astrakhan. Absent from the Sea of Azov. In Ref. 92840, it reported that this species reached the North Sea basin through an artificial waterway connecting the Danube with the Rhine (well-documented) and within 4 years, the species colonized all suitable riverhabitats downstream of the invasion site.
歐洲與亞洲: 多瑙河三角州;(Braila, 湖乳臭未乾的小孩) 湖 Kagul ， Yalpukh ， Katlabukh ， Kitai。 Kamentes-Podol'sk 的第聶伯河從 liman 到區域。 對 Dnepropetrovsk 的聶伯河; Odessa 與裡海的所有海岸; 而且在俄國羔皮的窩瓦河。 亞速海沒有出現。

Max length : 22.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 556)
This species is distinguished from related species in the Black Sea basin by the following characters: 75-95 % of distance between its origin and anus; ctenoid scales completely cover predorsal area and nape; pelvic disc fraenum with angular lobes, fraenum length 1/6-1/2 of its width at base; scales in midlateral series 68-72 + 3-4; snout length 1.5-2.0 times in eye diameter; first branched ray of second dorsal about as long as penultimate ray; posterior part of first dorsal without black spot (Ref. 59043).
Usually in freshwater and brackish water with very low salinity (< 2 ppt); in lower rivers and lagoons, lakes, large rivers, harbours on rocky or well-vegetated bottom (reed thickets) in still waters as well as rapids. Initial spawning at 2 years, in March to May, where adhesive eggs are deposited on stones, shells and aquatic plants; while males guard the eggs until hatching. (Ref. 59043). Feeds on crustaceans (mysids, corophiid amphipods) and small fish (gobies) (Ref. 4696).
出現於低的河川與潟湖,在岩石的底部上或在蘆葦叢中。 吃甲殼動物 (糠蝦, corophiid 片腳類動物) 與小魚 (鰕虎魚) 。 (參考文獻 4696)
