| Downstream migration of Atlantic salmon smolts was similarly unaffected by beaver dams, even in periods of low flows. |
| One or two years later, the smolts begin to migrate to the Pacific, where they live for one to three years before returning to the river. |
| Tailbeat frequency increases linearly with swimming speed in both parr and smolts. |
| Quantitative analysis of duty cycle shows a significant increase in duty cycle at each position between parr and smolts. |
| Young fish were also reared in hatchery tanks and released as smolts, the stage at which salmon head to sea before traveling to northerly feeding grounds. |
| Many species eat the fry and smolts, including striped bass, American shad, sculpins and sea gulls. |
