The offspring of the fish that mature in captivity are released as fry (newly hatched fish) in their first fall or as smolts (young fish beginning the first stage of their migration to the sea) in their second spring.
Les alevins obtenus sont relâchés vers la mer à leur premier automne ou à l'état de saumoneaux (petits poissons à leur première étape de la migration), au moment de leur second printemps.
