توصيف مختصر ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل): 17 - 19. Distinguished uniquely from its congeners by having roundish dark spots on body, mostly in 3 rows, first below dorsal base, and 50-55 + 4-5 scales along lateral line. Can be further separated from other species of the genus by having 17-19 dorsal spines (Ref. 59043).

زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Found in flowing waters and lakes with clear water. Also inhabits rapids during summer. Occurs over sand and gravel bottom but prefers hard compact sand. Usually crepuscular but feeds also during daytime. Preys predominantly on benthic invertebrates (crustaceans, insect larvae, molluscs), rarely on fish. Forms small schools. In September, starts forming large schools and moves to deeper places and remains inactive until ice melts. Does not undertake long distance migrations. Spawns in small schools river stretches with heavy current and sand or gravel bottom (Ref.59043).

Life cycle and mating behavior بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)

"Female lays slightly sticky eggs in several portions: first at 6-8°C, second at 12-14°C. Eggs hatch in 6-8 days at 14-16°C. Newly hatched larvae first lie on bottom; at 9 days (when pectorals are developed), they actively move to middle water layers and drift downstream. At 12 days (6.5mm) they start active feeding on small invertebrates in shallow shoreline habitats" (Ref. 59043).
