Pound net The oldest type of net used by the Chesapeake Bay watermen is called a pound net. Wooden stakes are pushed into the bottom of the Bay, spaced apart in a line that runs across the tide. Nets are strung between the stakes and along the bottom of the river, making a fish trap. In late February the pound netter starts to put in the stakes. By the middle of March he will set his nets and start fishing. Each day the waterman goes out to the pound net and scoops the fish out with a hand net. He will not remove the pound net, except for many repairs, until November. fishing,occupation,livelihood,Talbot County,Maryland

Hardened shoreline prevents erosion. Stone rip-rap installed by the property owners in an attempt to prevent shoreline erosion. Hardened edges along the Chesapeake Bay and its rivers reduces natural shoreline habitat that fish and other marine animals depend on for food and shelter. bulkhead,protection,stabilize,habitat,vegetation,amphibian,reptile,invertebrate,insect,wetland,marsh,river,tributary,Eastern Shore,Talbot County,Maryland
