The Maine Lobster Marketing Collaborative provides this list of practices that Maine lobstermen use while harvesting Maine’s staple resource:


  • Female Tail Notching: If a lobsterman catches a female lobster with visible eggs, she cannot be harvested. Before releasing her, the lobsterman notches her tail to identify her as a good breeder, protecting her from harvesting so that she may continue breeding for the rest of her life.
  • Minimum Size Limit: Lobstermen must throw back any lobster that has a carapace measuring less than 3 1/4″. This allows juvenile lobsters the opportunity to mature and reproduce before they are harvested.
  • Maximum Size Limit: Any lobsters caught in a trap that has a carapace measurement greater than 5″ must be thrown back to protect the large breeding stock.
  • Apprenticeship: All new lobster harvesters must apprentice with veterans to learn the regulated, sustainable practices before receiving their own fishing licenses in the state of Maine.
  • Trap Limits: The total number of traps each harvester is allowed to have is limited by both the state of Maine and individual lobster zones.
  • Harvest Method: Lobster harvesting in Maine is by trap only – no dragging or diving is allowed. The traps include escape vents for under-size lobsters, and also contain biodegradable escape hatches to free lobsters if a trap is lost.
  • Lobster Seed Fund: The Lobster Seed Fund purchases females that extrude their eggs after being harvested. This unique buy-back program helps to ensure that a good breeding stock is returned to the ocean to reproduce.
