For waterfront property owners to set a maximum of two crab pots at their property, provided that:

  • Pots are marked with the owner’s name and address or DNRid; and
  • Crab pots must have two cull rings, one measuring at least 23⁄16 inches and one at least 25⁄16 inches, located in the exterior side panel or the top panels of the pot.
  • Crab pots must have a turtle reduction device attached to each entrance or funnel in the lower chamber constructed of wire or plastic, rectangular in shape not larger than 1¾ inches high by 4¾ inches long.

Turtle Reduction Devices Are Required By Law

Turtle reduction devices are required in recreational crab pots in Maryland. These devices reduce the number of terrapins entering a crab pot without hindering blue crab entry. Without turtle reduction devices, terrapins can enter crab pots and drown. To get instructions for making or attaching a turtle reduction device, visit the Maryland Department of Natural Resources crab pot regulations page.
