Ecology of Alosa algeriensis
 
Main Ref. Kartas, F., 1991
Remarks 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).
