Descrição do ciclo de vida e do comportamento reprodutor | Depending on the subspecies some are semi-anadromous and spawn in fresh or slightly saline waters, mainly in the lower reaches, whereas others are practically marine and spawn in brackish or even fully saline oceanic waters (Ref.188).There are two migration peaks, one in late April (mostly males) and one in early May (mostly females). Spent fish migrate back to sea. Juveniles migrate to sea during first summer, remaining at sea until they mature (Ref. 59043). |
