Definition
回游 is a variant form of 洄游 (huí yóu), which means 'migration' — specifically the seasonal movement of fish or aquatic animals between saltwater and freshwater for spawning. In written Chinese, the standard form is 洄游, but 回游 appears occasionally as an alternative orthography. Both are read huí yóu.
