First Molecular Verification of a Marine-Collected Specimen of Alosa alabamae (Teleostei: Clupeidae)
Alosa alabamae (Alabama Shad) is an imperiled anadromous species that reproduces in northern Gulf of Mexico drainages. To date, there have only been 4 vouchered specimens collected from marine waters, but none have been verified with molecular techniques. On 28 March 2013, we collected a single adult female in proximity to a barrier island (Petit Bois) off the coast of Mississippi. Microsatellite DNA analysis corroborated the identification of this individual and suggested that the specimen was most genetically similar to the group from the Pascagoula River drainage rather than other portions of the range. Thus far, research has been focused on the species' freshwater life history, and it is crucial that more effort be directed toward documenting and understanding the full life history of this threatened fish.
