Anadromous — fish migrate from the sea up (Greek: ἀνά aná, "up" and δρόμος drómos, "course") into fresh water to spawn, such as salmon, striped bass, and the sea lamprey.
Catadromous — fish migrate from fresh water down (Greek: κατά kata, "down" and δρόμος dromos, "course") into the sea to spawn, such as eels.
Diadromous — George S. Myers coined the inclusive term diadromous in a 1949 journal article to refer to all fish that migrate between the sea and fresh water. Like the two aforementioned, well-known terms, diadromous was formed from Classical Greek ([dia], "through"; and [dromous], "running"), and proved a useful word, but terms proposed by Myers for other types of diadromous fish did not catch on. These included:
Amphidromous — fish that migrate from fresh water to the seas, or vice versa, but not for the purpose of breeding;
Potamodromous — fish whose migrations occur wholly within fresh water, and;
Oceanodromous — fish that live and migrate wholly in the sea.
