Crab Regulations and Methods of Take

Traditional Methods

Crabs can be harvested using various traditional methods, including:

  • Traps (pots)
  • Handline
  • Drop net
  • Dip net
  • Trawls

Special Provisions

  • Protection of Sponge Crabs: It is illegal to possess sponge crabs (egg-bearing crabs) at any time of the year. Sponge crabs must be immediately returned to the water alive.
  • Trap Usage Restrictions: Removing crabs from traps or pots without specific licensing is prohibited. Crab traps cannot be removed from the water between half an hour after sunset and half an hour before sunrise.
  • Size Regulations: Except for peeler crabs (about to shed) and soft-shell crabs (recently shed), all crabs must be at least 5 inches measured from one lateral spine across the back of the shell to the opposite lateral spine. Peeler crabs under 5 inches must be kept separate during commercial harvest.
  • Trap Marking: Crab trap floats must bear visible markings indicating the corresponding commercial or recreational crab license number. Vessel registration number is also required for traps fished from boats. Licensed commercial crabbers can register a buoy color code with Marine Patrol. Float lines must be made of non-floating or weighted material, easily cut with a knife, and at least 6 inches in diameter.
  • Ownership Identification: Each crab trap must be permanently marked with a corrosion-resistant metal or plastic tag bearing the license holder’s full name.
  • Escape Rings: Traps must have at least two escape rings on the vertical outside walls, with one in each chamber, each with a minimum inside diameter of 2 and 3/8 inches. These rings may be obstructed between April 1 to June 30 and September 1 to October 31 for retaining peeler or buster crabs.
  • Winter Sanctuary: Fishing for crabs is prohibited between January 1 and March 31 each year in the winter crab sanctuary west of Cat Island.

Incidental Catch

  • Crabs incidentally caught in trawls must be promptly returned to the water unless the boat operator possesses a valid Mississippi commercial crab license.
