首次成熟时的长度 / 大小 / 重量 / 年龄
成熟度: Lm 14.0, range 12 - 16 cm
Max length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 556); common length : 15.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 556); 最大体重: 250.00 g (Ref. 556); 最大年龄: 15 年 (Ref. 59043)
背棘 (总数) : 17 - 19. Distinguished from its congeners by having unique characters of 3 discontinuous dark stripes along flank and 55-62 + 4-5 scales along lateral line. Differs further from other species of the genus by having 17-19 dorsal spines (Ref. 59043).
Body shape (shape guide): fusiform / normal.
Adults occur in groups in open sand and mud bottom of large rivers with moderate current. Nocturnal, feeding on small invertebrates, especially molluscs, usually crepuscular but may also feed at daytime. Larvae are benthic (Ref. 59043).
栖息于多瑙河的较深部分, 在沙与碎石之上。 吃蠕虫,片脚类动物,昆虫幼生与鱼卵。 从四月到五月产卵。 卵在石头, 等等。上被在宽的地带附上
