Biology

Anadromous species. Occurs solitarily or in small groups; inhabits shallow waters of continental shelves. At the sea, it occurs in coastal and estuarine areas on soft bottom (Ref. 59043) down to a depth of 50 m (Ref. 89115). Adults are highly migratory while at sea (Ref. 57533) and make long migrations along the coast (Ref. 59043). They forage mainly in brackish waters (Ref. 59043). Ascend large rivers to spawn (Ref. 59043). Juveniles may remain in fresh or brackish water until 2-5 years of age or 76-91.5 cm long (Ref. 4639, 59043). Today most individuals do not exceed 250 cm length. Tagging studies have shown that this species may move distances up to 1,450 km (Ref. 89119). Used smoked and fresh (Ref. 37032). Near threatened globally, but extirpated in Europe due to massive overfishing, damming, river regulation and pollution (Ref. 59043).
