Female berried lobsters are off-limits to lobstermen, and even females who were at one time berried could be off-limits even without eggs. When a female lobster who is berried is hauled in a trap, lobstermen are required to “v-notch” the tail flipper to the right of center to indicate she was once caught as an egger. Females will eventually release their eggs in batches, but the v-notch will remain through several molting cycles. This allows the females to continue reproducing and populating the Gulf of Maine with another generation of lobsters. Maine has a zero-tolerance law for any female lobster caught with any deformity to the flipper right of center for this reason. As it turns out, 15-20% of lobsters caught in Maine are released because they are v-notched females, and even more from not meeting sizing requirements.
