CAMBRIDGE, Md. (AP) - An artificial oyster reef made up of 300 concrete balls has been completed in the Choptank River.
The reef was finished Saturday in the Bill Burton Fishing Pier adjacent to the Fredrick C. Malkus Bridge in Cambridge.
The two foot-tall igloo-like reef balls were set with baby oysters, or spat, by submerging them in large tanks of Chesapeake Bay water.
The reef balls were deployed throughout the summer.
