Description of life cycle and mating behavior "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).
