smolts
Juvenile migratory fish
Smolts are young salmon or trout at the stage when they develop silvery scales and migrate from freshwater to the sea.
This transformation involves physiological changes that prepare the fish for saltwater: The hatchery released thousands of smolts into the river.
Singular: smolt.
