Amphihaline species (Ref. 51442), schooling and strongly migratory, but apparently not penetrating far up rivers (Ref. 188). Enters tidal parts of rivers in May or early June to spawn there or a little above (Ref. 188, Ref. 51442). Spawning takes place at night over sand or gravel, at a temperature range of 15-20°C. Adults return to sea after spawning, and could later return to spawn a second or third time (Ref. 51442). Eggs are demersal, scattered over gravel or sand (Ref. 188). The fry move down river as they develop (Ref. 188). Ichthyophagous, feeds on small fishes and crustaceans, the young taking the fry of herrings, sprats and gobies (Ref. 188, Ref. 51442). Suffers from river pollution and to some extent from river barrages (Ref. 188). Sexually mature at an age of 3-4 years and a length of 30-40 cm (Ref. 35388).
