<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 />
