Abstract : Sturgeon are large, long-lived fishes that occur and spawn in most navigable 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 this reason, the U.S. Army of Corps of Engineers has funded studies of sturgeon since the early 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
