  • Habitat Use of Juvenile Pallid Sturgeon and Shovelnose Sturgeon with Implications for Water-Level Management in a Downstream Reservoir
    North American Journal of Fisheries Management 28:832–843, 2008 [Article] Ó Copyright by the American Fisheries Society 2008 DOI: 10.1577/M07-061.1 Habitat Use of Juvenile Pallid Sturgeon and Shovelnose Sturgeon with Implications for Water-Level Management in a Downstream Reservoir 1 PAUL C. GERRITY* AND CHRISTOPHER S. GUY U.S. Geological Survey, Montana Cooperative Fishery Research Unit, 301 Lewis Hall, Montana State University, Bozeman, Montana 59717, USA WILLIAM M. GARDNER Montana Department of Fish, Wildlife and Parks, Post Office Box 938, 215 Aztec Drive, Lewistown, Montana 59457, USA Abstract.—Natural recruitment of pallid sturgeon Scaphirhynchus albus has not been observed in the Missouri River above Fort Peck Reservoir, Montana, for at least 20 years. To augment the population, age-1 hatchery-reared juvenile pallid sturgeon were released in 1998. The objective of this study was to evaluate the habitat use of these fish and compare it with that of indigenous shovelnose sturgeon S. platorynchus. Twenty- nine juvenile pallid sturgeon and 21 indigenous shovelnose sturgeon were implanted with radio transmitters in 2003 and 2004. The two species showed no differences in habitat use in terms of mean depth, cross-sectional relative depth, longitudinal relative depth, column velocity, bottom velocity, and channel width. However, there were seasonal differences within both species for cross-sectional relative depth, column velocity, and channel width. Both shovelnose sturgeon and juvenile pallid sturgeon were primarily associated with silt and sand substrate. However, shovelnose sturgeon were associated with gravel and cobble substrate more than juvenile pallid sturgeon. Shovelnose sturgeon and juvenile pallid sturgeon both selected reaches without islands and avoided reaches with islands; the two species also selected main-channel habitat and avoided secondary channels.

    U.S. Fish & Wildlife Service Natchitoches National Fish Hatchery The Natchitoches National Fish Hatchery is one of many units in the National Fish Hatchery System administered by the U.S. Fish and Wildlife Service. The service also manages more than 500 national wildlife refuges across the country. As the nation’s primary steward of fish and wildlife resources, the Service provides leadership in habitat and wetlands protection; fish and wildlife research and technical assistance; and in the conservation and protection of migratory birds, anadromous fishes, certain marine mammals, and threatened and endangered species. Welcome to the Natchitoches National Fish Hatchery The Natchitoches National Fish Hatchery became operational in 1931 under the authority of the White Act as a warm water facility that would produce catfish, largemouth bass, bluegill, and redear sunfish for local public waters and farm photo: USFWS photo: ponds. Since 1931, resource needs in the southeast have changed and the mission of the station has changed with the times. We currently raise three species of fish: striped bass, National Fish pallid sturgeon, and paddlefish.

  • US Fish & Wildlife Service Revised
    U.S. Fish & Wildlife Service Revised RECOVERY PLAN for the Pallid Sturgeon (Scaphirhynchus albus) Original Plan Approved: November 1993 Prepared by: Pallid Sturgeon Recovery Coordinator U.S. Fish and Wildlife Service Montana Fish and Wildlife Conservation Office Billings, Montana For Mountain-Prairie Region U.S. Fish and Wildlife Service Denver, CO January 2014 DISCLAIMER Recovery plans delineate reasonable actions that are believed necessary to recover and/or protect listed species. Plans are prepared by the U.S. Fish and Wildlife Service, sometimes with the assistance of recovery teams, contractors, State agencies, and others. Plans are reviewed by the public and subject to additional peer review before they are adopted by the U.S. Fish and Wildlife Service. Objectives will only be attained and funds expended contingent upon appropriations, priorities, and other budgetary constraints. Recovery plans do not obligate other parties to undertake specific tasks. Recovery plans do not necessarily represent the views nor the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service. They represent the official position of the U.S. Fish and Wildlife Service only after they have been signed by the Regional Director or Director as approved. Approved recovery plans are subject to modification as dictated by new findings, changes in species’ status, and the completion of recovery tasks. Copies of all documents reviewed in development of the plan are available in the administrative record, located at the U.S. Fish and Wildlife Service’s Montana Fish and Wildlife Conservation Office, Billings, Montana.
