| Typical size | 18–24 in, 2–5 lb |
|---|---|
| Maximum | up to 30 in and about 12 lb |
| Lifespan | up to about 13 years |
| Range | Native to the Atlantic coast from the Canadian Maritimes south to the St. Johns River in Florida and long established on the Pacific side, where millions push up the Columbia and Snake rivers and strays run from Baja to Alaska. |
| Habitat | An ocean fish most of the year that stacks in heavy river current below dams and along gravel drop-offs during the spring spawning run. |
| Diet | Plankton, copepods and mysids at sea; run fish largely stop feeding and hit small darts, spoons and flashy jigs out of reflex. |
Sizes are typical rod-and-reel and documented maximum figures, not size limits — see the regulations links below for the rules where you fish.
Tell it apart: The serrated 'cutting-edge' scutes along the belly keel plus the dark shoulder spot ID an American Shad among silvery PNW fish.
