定義： An oceanodromous fish, like an anadromous or catadromous fish, is migratory. Unlike anadromous or catadromous fish, an oceanodromous fish spends its whole life in salt water.
定義： Planktotrophic species generally have fairly long pelagic larval durations and feed while in the water column. Consequentially, they have the potential to disperse long distances.
