This colorful chart details oyster fishing beds throughout Chesapeake Bay and part of Chincoteague Bay. The map locates Washington, D.C., Annapolis, Baltimore and more with fine detail throughout. It locates areas where oyster gathering is authorized, and by which method, as shown by the color-coded key at upper left. By the 1870's, Maryland's oyster fields were becoming severely depleted, which led to oyster management efforts in the form of laws and regulations. This informative map is from one of the reports documenting that effort.
