Notas | This species undertakes anadromous breeding migrations from the sea, where it spends most of its life, into the freshwater sections of rivers; it can also live permanently in brackish water (Ref. 10538). Males migrate upriver at 3-4 years, females at 4-5 years; it starts entering rivers when temperatures reach 14-18°C, mainly in May, and spwaning commences when temperature rises above 20°C in May and June (Ref. 59043). The spawners return downstream immediately after spawning (Ref. 10538). |
