Cruise ships threaten lobster For 40 years, I did summer research at the MDI Biological Laboratory, then retired here and joined the Maine Lobstermen’s Association as a “friend.” A recent BDN article described how Maine lobstermen’s practice of “V-notch” marking tails of egg-carrying lobsters before returning them to the sea and only harvesting lobsters within a specific size range is credited with saving the population here, a product of prudent management. As a biologist, I suggest that the lobster population of Frenchman Bay belongs not just to the town of Bar Harbor but to all towns and fishermen surrounding the bay and cruise ship proposals before the Bar Harbor Town Council threaten that lobster population.
