The silver seatrout (Cynoscion nothus), also known as white trout, sugar trout, and silver weakfish, is a species of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers.

The species is found in the western Atlantic, across the eastern areas of coastal North America and in the Bahamas.

Like many weakfish species, they have vampire-like fangs on their upper jaw, well as smaller teeth throughout the entire mouth.

[2] Silver seatrout are caught mostly in bottom trawls, particularly as bycatch in shrimp fisheries, and with pound nets.

No separate statistics are reported for silver seatrout landed and this species is likely to be confused for Cynoscion regalis in landings along the eastern coast of the United States and for C. arenarius in the Gulf of Mexico.
