Abstract: Sturgeon are large, long-lived fishes that occur and spawn in most navigation rivers in the United States. Few groups of North American fishes have such an extensive range. In North America, sturgeon represent nine taxa in two genera (Acipenser and Scaphirhynchus). Four of these taxa are listed as threatened or endangered under the Endangered Species Act. Because sturgeon occur in main channels of rivers, they are vulnerable to the effects of flood control, navigation, and hydroelectric projects. For thsi reason, the U.S. Army Corps of Engineers has funded studies of sturgeon since the earl 1980s. Section 7 of the Endangered Species Act directs the Corps to protect the species according to recommendations specified by the U.S. Fish and Wildlife Service. However, it is difficult to formulate management strategies with the limited life history information that is available on the species. Protection and management of sturgeon has recently been recognized as a major environmental issue for the Corps. The issue was highlighted at the 1993 meeting of the Environmental Advisory Board in Portland, Oregon, and later at a sturgeon workshop conducted by the Corps' South Atlantic Division. A 3-year research unit to study sturgeon in the continental United States was begun in fiscal year 1995, as part of the Corps' Environmental Impact Research Program (EIRP). This article presents life history information on the species, outlines sturgeon issues related to Corps operations and maintenance activities, and summarizes current research priorities.
