  1. Development and Implementation of Freshwater Species Recovery Efforts in Alabama Paul D. Johnson, Ph.D. Alabama Department of Conservation and Natural Resources Alabama Aquatic Biodiversity Center Marion, Alabama

  2. Cahaba River, Shelby County • Alabama Aquatic Biodiversity Center (AABC) • Division of Wildlife and Freshwater Fisheries • Department of Conservation and Natural Resources • Not part of the state general fund • Primary funding state wildlife and other external funds • No regulatory authority • http://www.outdooralabama.com

  3. AABC Mission: • Promote recovery of imperiled non-game aquatic species • Coordinate / direct research efforts for rare species • Promote habitat / river recovery efforts • Complete species restoration through reintroduction

  4. INTRODUCTION: • Aquatic diversity summary • Species recovery methods • Site selections • Example reintroductions

  5. Alabama Physiographic & River Basins

  6. Pleurobemarubellum- Warrior Pigtoe Distributions of Freshwater Species in Selected Southeastern States Mussels Snails Crayfish Fish Amphibians(301) (702) (338) (1024) (163) Alabama 181 204 85+ 308 69 Tennessee 132 87 62 298 66 Georgia 119 83 53 219 81 Kentucky 103 62 47 220 49 Mississippi 85 35 64 204 59

  7. Alabama Federally Listed Species 308 Species 15 federally listed 182 Species 52 federally listed 204 Historical 12 federally listed 85+ Species 0 federally listed

  8. Mollusk Recovery Planning PLAN FOR THE POPULATION RESTORATION AND CONSERVATION OF IMPERILED FRESHWATER MOLLUSKS OF THE MOBILE RIVER BASIN Prepared by the: Mobile River Basin Mollusk Restoration Committee January 2010

  9. Southern Pocketbook, Lampsilis ornata – Cahaba River

  10. 1. Artificial culture process for freshwater mussels: 4. 2. 3.

  11. Partial Flow-Thru Bucket Culture System: Modified from figure in Barnhart et al 2006

  12. SUPSYS – Open Water Mussel Culture Chamber:

  13. Lampsilis virescens– in SUPSYS 14 days

  14. Lampsilis virescens– in SUPSYS 135 days

  15. In-Situ Pre-Release Photo of a single silo placed in possible release site. Upwelling cup containing juvenile musselsplaced in silo. 1 mm mesh

  16. Deployed Mussel Silo

  17. July 8, 2010 Villosanebulosa – Choccolocco Creek Silo Test @ week 4. Note growth around ventral shell margin. August 4, 2010

  18. Choccolocco Creek, Talladega County Larger channels preferred: * Higher productivity, more heterogeneity, larger surface, discharge more stable * Animals positively rheotaxic * Improved colonization rate and population size potential

  19. Bear Creek, Colbert County, Reintroductions: Alabama Lampmussel 1,039 Individuals = 28 pounds Cumberland Moccasinshell 140 Individuals

  20. June 14, 2012 Alabama Lampmussel recaptures - Bear Creek, Colbert Co., AL

  21. ≈ 9,000 Leptoxis plicata awaiting release

  22. Locust Fork Reintroduction Monitoring: Juvenile Leptoxis plicata at Wallstown release site, Blount County, Alabama. Snails recruited from 2011 released cultured snails. June 13, 2011

  23. Plicate Rocksnail reintroduction site on the Locust Fork of the Black Warrior River, Blount County Alabama. October 16, 2005

  24. Plicate Rocksnail reintroduction site on the Locust Fork Black Warrior River, Blount County Alabama. August 26, 2010

  25. Locust Fork – Black Warrior River : Etowah 2. Locust Fork Site Blount Walker 3. Wallstown Site Jefferson 1. Kimberly Site

  26. Culture & Reintroduction Process: • Survey • Location of Reintroduction Site • Brood Stock Allocation • Culture • In-Situ Silo Trial • Reintroduction • Evaluation of Persistence • Augmentation • Verification of Recruitment • Basic research is a requirement • Lack of WQ stability impedes recovery • Habitat monitoring SHU process benefits more than imperiled spp.
