An anadromous fish, born in fresh water, spends most of its life in the sea and returns to fresh water to spawn. Salmon, smelt, shad, striped bass, and sturgeon are common examples. A catadromous fish does the opposite - lives in fresh water and enters salt water to spawn. Most of the eels are catadromous.

If the fish does this for fun rather than to breed it is classed as an "amphidromous" species. If the fish lives mainly in the ocean and travels into fresh water to breed then it is "anadromous". Salmon come into this category.
