A young hatchling, about 3-5 inches in length, that is ready to travel away from its hatching area.
A young salmon or sea trout, silver in color on its first journey to the sea.
A juvenile, silvery salmon up to 15cm long, which has lost its parr marks and has attained the silverly coloration of the adult. This coloration signifies the readiness of the young fish to migrate to the seas and its ability to adapt to the water environment.
Life stage of salmon between the parr and adult stages. At this stage, the young salmon are silver in color and migrate to the sea.
A juvenile anadromous fish that has undergone physical changes to prepare for life in salt water.
A juvenile salmonid that is undergoing the physiological change to migrate from fresh to salt water.
life stage in salmonid fishes; individual usually 1-3 years of age, turning silvery, preparing to migrate out of stream or lake or sea, or out of stream to large lake
a young, silvery salmon over two years old, but still living in a river and leaving for the sea in the Spring
The stage in the life of salmon and similar fishes in which the subadult individuals acquire a silvery color and migrate down the river to begin their adult lives in the open sea.
Young fish entering the first stage of their migration.
A characteristic stage in the life cycle of most salmonids: the juvenile salmonid at the time of physiological and physical pre-adaptation to the marine life.
The life stage of a salmon or trout in which it first enters the sea.
young salmon migrating to the ocean and undergoing biological changes to enable them to move from fresh water to salt water.
a young silvery salmonid migrating to the sea
Refers to the salmonid or trout developmental life stage between parr and adult, when the juvenile is at least one year old and has adapted to the marine environment.
A juvenile anadromous salmonid which is undergoing the physiological and behavioral changes required to migrate from fresh water to salt water.
A juvenile salmonid migrating to the ocean and undergoing physiological changes (called smoltification) to adapt from a freshwater to a saltwater environment.
A juvenile salmon or steelhead migrating to the ocean and undergoing physiological changes to adapt from a freshwater to a saltwater environment.
Young salmon, migrating downstream from freshwater to saltwater. When parr become smolts, they lose their spots and turn silvery.
Juvenile salmonid at the time of physiological adaptation to life in the marine environment.
The life stage of anadromous fish during which physiological changes prepare it for transition from freshwater to marine life; generally occurs at the onset of active downstream migration.
a young salmon or sea trout about two years old that is at the stage of development when it assumes the silvery color of the adult and is ready to migrate to the sea
A young salmon undergoing physical changes in preparation for entering salt water.
A salmon of a certain size, generally 4-7 inches, that begin seaward migration and smoltification.
An anadromous fish that is physiologically ready to undergo the transition from fresh to salt water; age varies depending on species and environmental conditions.
Young fish that have been imprinted. In South Dakota, chinook salmon are imprinted to Whitlocks Station.
a juvenile salmon about two years old, the age where it migrates from its freshwater spawning ground out to the ocean.
a juvenile salmon or steelhead that has attained readiness to migrate to sea; parr marks are lost and silver color taken on; gills and kidneys change from retaining to excreting salt.
A juvenile anadromous fish that is physiologically ready to undergo the transition from fresh to salt water. Smolts typically measure from approximately 60 mm to 80 mm fork length.
