2.3. <br />effects of increased sediment supply and changing hydrographs <br />on bed condition. <br />2.2.5 Determine the need for fish bypass facilities. <br />The U.S. Army Corps of Engineers should determine the need and <br />practicality of a bypass facility for pallid sturgeon at Ft. <br />Peck Dam, thereby providing for migration between two recovery - <br />priority areas. The U.S. Bureau of Reclamation should <br />determine the need and practicality of a bypass facility around <br />the low -head diversion dam at Intake, Montana, on the <br />Yellowstone River thereby providing migration within that <br />recovery - priority area. <br />2.2.6. Determine the impact of sturgeon commercial and sport fishing <br />on pallid sturgeon. <br />States allowing commercial and sport fishing for sturgeon may <br />be facilitating the incidental take of pallid sturgeon. In <br />addition to hampering recovery efforts, this may also place <br />fishermen in a situation of violating the Endangered Species <br />Act should they fail to properly identify and protect pallid <br />sturgeon. States should closely monitor sport and commercial <br />sturgeon fishing to determine numbers of pallid sturgeon <br />captured, locations, and gear or technique used. <br />2.2.7. Determine diagnostic characteristics to distinguish between <br />eggs of sturgeon and paddlefish species. <br />Enforcement of protection regulations under the Endangered <br />Species Act and CITES will require law enforcement agencies to <br />distinguish between eggs of paddlefish and sturgeon and among <br />sturgeon species. Legal trade in paddlefish and unprotected <br />sturgeon eggs for caviar provide a market for eggs of protected <br />species like pallid sturgeon. <br />Obtain information on genetic makeup of hatchery- reared and wild <br />Scaphirhynchus stocks. <br />2.3.1. Determine the degree of genetic divergence between <br />Scaphirhynchus species within the range of pallid sturgeon. <br />Genetic analysis of Scaphirhynchus species within the range of <br />pallid sturgeon is necessary to determine genetic divergence <br />for management purposes. Pallid sturgeon and shovelnose <br />sturgeon have been distinguished based upon morphometric and <br />meristic characteristics and character ratios (Bailey and Cross <br />1954; Williams and Clemmer 1991). Hybridization between pallid <br />sturgeon and shovelnose sturgeon has been proposed based upon <br />these same characteristics. Phelps and Allendorf (1983) were <br />unable to distinguish the species electrophoretically by <br />33 <br />
