Open SlotGauge for River HerringSpecies of North American shad
The alewife or river herring is a species of herring found in North America. It is commonly anadromous but there are also significant landlocked populations. It is one of the smaller species of shad, of the subgenus Pomolobus. As an adult it is a marine species found in the northern West Atlantic Ocean, moving into estuaries before swimming upstream to breed in freshwater habitats, but some populations live entirely in fresh water.
