| 生命周期与交配行为的描述 | Adults ascend rivers between June and October (northern Baltic) or November (southern Baltic), when water temperature drops below 10 °C. Spawning occurs in estuarine areas with low salinities or lower reaches of rivers or rapids (Ref. 59043). Coregonus species spawn on gravel and sand bottoms (Ref. 35387). Spawns for the first time at 3-5 years. Some females spawn only every second year (Ref. 59043). Spawners may spend the winter in rivers or near estuaries along the coast (Ref. 89484). Eggs hatch in early spring and larvae drift downstream to estuarine bays or to the sea; juveniles migrate to the sea in summer (Ref. 59043). |
