MOBILE, Ala. – The U.S. Army Corps of Engineers, Mobile District announces the commencement of a comprehensive fish tagging study in the lower Alabama River. This initiative aims to understand the movement patterns of fish through the locks and dams in the region, particularly during spring migration.

The Mobile River basin, around the Alabama and Tombigbee Rivers, is a vital ecosystem supporting diverse aquatic species and habitats with more than 180 fish species, including many endemic species.

The data collected from this study will provide valuable insights into fish migration patterns within the river system. By understanding how fish navigate through the locks and dams, the Mobile District aims to enhance conservation efforts and ensure the sustainability of aquatic ecosystems in the region.

As part of the study, fish are captured and tagged with small tags near their dorsal fin. It is important to note that anglers may still keep and consume tagged fish in accordance with state law.

Anglers encountering fish with these tags are encouraged to contact Mobile District biologist Terry Rickey at (251) 694-3857 or via email at
