Fish that spend a part of their life cycle in the sea and return to freshwater streams to spawn.
Fish that are born and reared in freshwater, move to the ocean to grow and mature, and return to freshwater to reproduce (e.g., salmon, steelhead, and shad).
Fish that spend most of their lives at sea but ascend rivers to spawn
Species of fish that mature in the sea and migrate into streams to spawn. Most species are now endangered; the Umpqua cutthroat trout is an example.
Fish, such as salmon or steelhead trout, that hatch in fresh water, migrate to and mature in the ocean, and return to fresh water as adults to spawn.
(1) Fish which mature in ocean water and spawn in fresh water. (2) Pacific salmon, sea-run cutthroat trout, steelhead, sea-run dolly varden, oolichans.
Fish that hatch in freshwater, migrate to the ocean, mature there and return to freshwater to spawn. For example, salmon or steelhead.
Fish that migrate up rivers from the sea to breed in fresh water.
Fish that breed in fresh water but spend most of their adult lives in salt water. Examples are salmon and striped bass.
Species that are hatched in freshwater, mature in saltwater, and return to freshwater to spawn.
Fishes living in the ocean (or other large waterway) but which enter fresh water (in the case of lake-dwellers, smaller) streams to spawn.
Fish which at certain seasons ascend rivers from the sea or ocean to spawn, e.g., salmon.
fish that spend part of their lives in fresh water, some in salt water, and then mate and produce offspring in fresh water. Salmon are anadromous fish.
Fish (such as salmon and steelhead) that hatch in freshwater, migrate to the ocean, mature there, and return to freshwater to spawn.
A fish that is born in fresh water, spends its life in salt water, and migrates back to fresh water to spawn.
Fish that are born in freshwater, live in saltwater, and return to freshwater to spawn
Fish that are born in freshwater, migrate to the ocean to grow and mature, and return to freshwater as adults to reproduce.
Fish that spend most of their lives in saltwater, but migrate into freshwater tributaries to reproduce (spawn).
Fish that spends most of its life feeding in the open ocean but that migrates to spawn in fresh water (e.g., Salmon).
Fish that reproduce and live the first part of their lives in fresh water, then migrate to the ocean to spend their adult lives. The time in the ocean may be as short as six months or as long as seven years before the fish return to freshwater to spawn. Salmon and steelhead are anadromous fish.
Fish that spend most of their lives in saltwater, but return to freshwater to spawn and develop.
A species, such as salmon, alewives, or river herring, that is born in fresh water, spends a large part of its life in the sea, and returns to freshwater rivers and streams to procreate.
Fish that hatch in freshwater, migrate to the ocean to mature, then return to freshwater to spawn.
Fish that live in saltwater habitats most of their lives, but periodically migrate into freshwater to spawn and develop to the juvenile stage (e.g., alewife).
fish such as American shad that migrate from their primary habitat in the ocean to freshwater to spawn
In general, anadromous fish are fish that rear in freshwater, migrate to the ocean and return to freshwater rivers to spawn. Title 34 specifically defines anadromous fish as "...those stocks of salmon (including steelhead), striped bass, sturgeon, and American shad that ascend the Sacramento and San Joaquin rivers and their tributaries and the Sacramento-San Joaquin Delta to reproduce after maturing in San Francisco Bay or the Pacific Ocean" (Section 3403(a)).
Fish that are born and rear in freshwater, move to the ocean to grow and mature, and return to freshwater to reproduce. Salmon, steelhead, and shad are examples. ( FEMAT, IX-2)
Fish that hatch in fresh water, mature in salt water, and return to fresh water to spawn.
Migratory species that are born in freshwater, live mostly in estuaries and ocean water, and return to freshwater to spawn.
