Alabama Aquatic Biodiversity Center Fact Sheet

Many species of mollusks, like the Spiny Riversnail (Io fluvialis) are either extinct or missing from state waters. The AABC will lead efforts to return many species to state waters, where future generations of Alabamians will benefit from the clean water initiatives these unique animals can promote.

The Alabama Aquatic Biodiversity Center (AABC) is the largest state non-game recovery program of its kind in the United States. The mission of AABC is to promote the conservation and restoration of rare freshwater species in Alabama waters and in turn, restore cleaner water in Alabama's waterways.

Alabama is known to have the greatest number of freshwater species of mollusks and fish in the United States. However over the past 80 years, Alabama has lost over 67 species of these mollusks and fish to extinction. The U.S. Fish and Wildlife Service have listed more than 54 species as threatened or endangered in Alabama's waters. AABC will help to restore threatened or endangered species of mollusks and fish through propagation and restoration. By culturing, restoring and conserving these species, we can help aid in clean water efforts in Alabama's waterways.

According to the U.S. Environmental Protection Agency, 183 lakes and streams in Alabama are considered troubled water bodies. Even though this is far less than other states including Georgia, Tennessee and Mississippi, introducing mollusks into streams and waterways will promote water-quality improvements throughout in the state.

Mollusks act as Mother Nature's vacuum cleaner by filtering water through their bodies. In the most basic terms, they are filter feeders who suck in water and pull out bacteria and suspended solids. A small mussel can filter over 12 gallons of water per day. In healthy ecosystems throughout the Southeast, freshwater mollusks historically numbered in the hundreds of millions.

To restore the mollusk populations in Alabama, the Center will first target Mobile River Basin species because these are the most endangered groups that we have in Alabama. Initially, the Coosa River at the Weiss Lake bypass will be the first targeted waterway.

The Department of Conservation is also assisting in additional outreach efforts in Alabama such as requiring and monitoring sanitation devices on boats to further promote water-quality issues through the Alabama Clean Boating and the Clean Vessel Act.

The Alabama Aquatic Biodiversity Center is located near the City of Marion in rural Perry County, Alabama. The Center is a complex of four buildings that sits on 36 acres of property near the Cahaba River and adjacent to the Marion State Fish Hatchery, Perry Lakes Park, and The Nature Conservancy's Barton's Beach Preserve. The facility was last operated by the U.S. Geological Survey (USGS), Biological Resources Division, as the Claude Harris National Aquiculture Research Center. In 1995, the USGS closed the facility, and the property was deeded to the State of Alabama from the U.S. Department of Interior in 1999.

The facilities at the Center include three aquatic culture buildings with over 7,500 square feet of space under roof, a 4,300-square-foot administration building with office and laboratory space, and approximately 30 surface acres of aquatic culture ponds.

A staff of nine employees is planned to begin the program. Five full-time employees are currently employed at the Center. The Program Supervisor is Dr. Paul Johnson, former Director of the Tennessee Aquarium Research Institute, who joined the program in October 2005. The telephone number is (334) 683-5000.

Note: In Alabama, it is illegal to stock or move any fish, mussel, snail or crayfish to any public water without a permit.
