| Notes | American shad is a kind of herring native to the Atlantic coast of North America. Like the salmon, it is anadromous, spending part of its life cycle in freshwater and part in the ocean. Between 1871 and 1886, shad were introduced to the Sacramento River in California and to the Columbia River. These introductions were enough to allow the fish to spread along the west coast, and there is a significant population resident in the Umpqua River. In this article, the authors explain how they were able to use genetic microsatellite locations to identify different populations of shad. They explore what genetic differences can tell them about the different populations. It is interesting to note that some shad in the Columbia River have adopted unique freshwater life cycles, and one landlocked population also has a freshwater life cycle. The data tends to show that most shad are faithful to the locations where they have spread, and tend not to stray much beyond the original founding event. This is true of the shad in the Umpqua River. |
