| Descrição do ciclo de vida e do comportamento reprodutor | Females spawn with several other species, for example Cyprinus carpio and Carassius carassius, but the eggs just develop without being actually fertilized resulting in a female only population (Ref. 2059). In Europe, populations considered as triploid and only females. But in some populations, it should be possible to find up to 25% of males which should be diploid (Ref. 40476). "There are also all-female populations in which all individuals are triploids. Triploids are sperm parasites of other cyprinid species such as Cyprinus carpio, Rutilus rutilus and Abramis brama. Older individuals spawn earlier in season than younger ones. Males move to spawning sites before females. Males follow ripe females, often with much splashing. Sticky eggs are attached to water plants or submerged objects" (Ref. 59043). |
