Resumo:
The crab pot as a fishing gear was introduced in Maryland waters, following some years of greatly expanded use in Virginia, during the 1939 season, and was widely used during 1940. The 1941 session of the Maryland Legislature, however, illegalized the crab pot. Since that time the device has been given up almost entirely by Maryland fishermen, its attempted use in a commercial way having persisted in diminishing numbers in only one region of the state.
