Occurs in coastal seas, estuaries and rivers. An annual species, with an anadromous life cycle. In spring, large shoals of adults migrate from the sea into rivers and estuaries to spawn. Eggs are deposited on the bottom or among debris. They hatch in 2-3 weeks, and the fry are swept out to sea where they undergo development. Adults die shortly after spawning. Also known as Derwent whitebait (Ref. 44894).
