Anadromous. Inhabits coastal and estuarine zones at the sea. Breeds in strong-current habitats in main course of large and deep rivers on stone or gavel bottom. Juvenile stay in riverine habitats during their first summer (Ref. 59043). Adults migrating to breed take the path of short, fast flowing mountain rivers (Ref. 33773). Maximum reported length for female is 176.1 cm TL(Ref. 58888).
