<strong>Alabama</strong> Aquatic Biodiversity Center:<br />
n Culture and refit activities at the <strong>Alabama</strong> Aquatic Biodiversity<br />
Center (AABC) focused on final hatchery refit, establishment<br />
<strong>of</strong> culture systems, initiation and continuation <strong>of</strong> artificial<br />
propagation and captive culture, and general survey efforts in<br />
<strong>2010</strong>. Hatchery construction and refit were devoted to the main<br />
wet lab with water distribution manifolds, husbandry electrical<br />
support, diagnostic laboratory refit, and humidity controlling<br />
structures were completed in <strong>2010</strong>. Culture systems were<br />
designed and installed in the wet lab, culture pavilion, and two<br />
different ponds.<br />
n Greater emphasis on culture efforts were made in <strong>2010</strong> as more<br />
than 60,000 mussels <strong>of</strong> seven different species (five Threatened<br />
and Endangered) along with 10,000 snails <strong>of</strong> 10 species (seven<br />
Threatened & Endangered) were propagated.<br />
n The AABC completed a number <strong>of</strong> stockings including the<br />
Cahaba River (Leptoxis picta, Elimia olivula, Pleurocera clarkii<br />
– 7,930), Locust Fork (13,200 - 1-year old federally endangered<br />
Leptoxis plicata), Choccolocco Creek (1,300 – Villosa nebulosa<br />
at 2 locations), Paint Rock River (10 federally endangered<br />
Villosa trabilis 10 at one location and 600 Lampsilis virescens<br />
at two locations). In addition the AABC donated 400 cultured<br />
L. virescens to the Tennessee Wildlife Resources Agency for<br />
release in the Elk River, Tennessee. Initial culture for mussels in<br />
ponds performed exceptionally well in specially constructed<br />
SUPSYS (suspended upwelling system) chambers with several<br />
listed species growing from 4 mm to 40 mm shell length in the<br />
systems within 120 days (Hamiota altilis, H. perovalis, and L.<br />
virescens). Nine mussel species were successfully cultured in the<br />
SUPSYS systems in <strong>2010</strong> including Strophitus connasaugaensis,<br />
Medionidus conradicus, Lampsilis teres, Lampsilis fasciola,<br />
Villosa iris, and Villosa nebulosa. A summary <strong>of</strong> mollusk<br />
stockings conducted in FY <strong>2009</strong>-10 is provided in Table 3 on<br />
page _##_<br />
n AABC staff also participated in conservation planning, general<br />
survey activities and research efforts in FY <strong>2010</strong>. AABC staff<br />
assisted with the completion <strong>of</strong> mollusk conservation planning<br />
efforts with the Tennessee/Cumberland fauna and developed<br />
a species list for the Eastern Gulf Slope plan. The Mobile River<br />
Basin mollusk conservation priority document will be completed<br />
in early 2011. AABC staff assisted in the initiation <strong>of</strong> a non-game<br />
fish recovery planning document with the Southeastern Fishes<br />
Council and Southeast Aquatic Resource Partnership. These<br />
documents will identify species targets and their conservation<br />
priorities for the planning documents for the Mobile and<br />
Tennessee/Cumberland River basins.<br />
n AABC staff completed survey efforts in the <strong>Alabama</strong> River (30<br />
sites) and the lower-Cahaba River (54 sites) in FY <strong>2010</strong>.<br />
n AABC staff also continued work on the Pleuroceridae Type<br />
Catalog Project by traveling to both the National Museum <strong>of</strong><br />
Natural History in Washington D.C. and the Academy <strong>of</strong> Natural<br />
Sciences in Philadelphia, Pennsylvania. This project, now in its<br />
third year, has captured images <strong>of</strong> over 500 type specimens<br />
deposited in various museums across the North America and<br />
Europe. Approximately 250 final composite plates have already<br />
been generated and the North Carolina Museum <strong>of</strong> Natural<br />
History and the United States Natural History Museum are<br />
partners on the project.<br />
n AABC staff has also worked towards the completion <strong>of</strong> the first<br />
<strong>Conservation</strong> Status Assessment for North America Freshwater<br />
Gastropods produced for the American Fisheries Society.<br />
n AABC staff also participated in research efforts with freshwater<br />
mussel anatomy and bacterial community assessment<br />
completed at Auburn University and systematics revision <strong>of</strong><br />
Leptoxis spp. completed at the University <strong>of</strong> <strong>Alabama</strong>.<br />
Problems/Solutions<br />
Public Fishing Lakes:<br />
n Bass crowding continues to be a problem statewide. Removal <strong>of</strong><br />
bass by the use <strong>of</strong> anglers and/or electr<strong>of</strong>ishing gear, along with<br />
judicious use <strong>of</strong> other treatments, will be employed to manage<br />
overcrowded bass populations. Lakes are being renovated as a<br />
final solution.<br />
n Recruitment <strong>of</strong> qualified lake managers at rural state lakes<br />
continues to be a problem.<br />
Riverine Habitat:<br />
n The loss <strong>of</strong> riverine habitat in <strong>Alabama</strong> has resulted in the<br />
decline or loss <strong>of</strong> obligate riverine fishes and mollusks. Efforts<br />
continue to document habitat loss and provide suitable<br />
wildlife Section<br />
Twenty-four <strong>Alabama</strong><br />
caves were surveyed<br />
and/or searched for bat<br />
species. Nongame Program<br />
personnel served on the<br />
<strong>Alabama</strong> Bat Working Group<br />
committee and assisted<br />
with the completion <strong>of</strong><br />
the <strong>Alabama</strong> White-nose<br />
Syndrome Management<br />
Plan.<br />
