    Rivers Project Biologists working with the Missouri Department of Conservation regularly monitor fish on the Mississippi River. They embed acoustic tags by cutting a small incision in the abdominal cavity of the fish and inserting the small tube-like tag. These sounds can be detected by specialized receivers, and processed to determine if a fish swimming into the reception area carries a specific acoustic tag, giving biologists information on where the fish has traveled.
