An overview of native and invasive crayfish in Mississippi and Alabama
Abstract
Mississippi has approximately 63 crayfish species and no known invasive crayfish. Whereas Alabama has about 97 species, including at least three non-natives: the Kentucky River crayfish (Faxonius juvenilis), the gray-speckled crayfish (F. palmeri palmeri), and the virile crayfish (F. virilis). In addition, the red swamp crayfish (Procambarus clarkii) is probably native on Alabama’s Gulf Coastal Plain but introduced elsewhere in the state.
