Baby lobsters are continuing to appear in high numbers off some parts of Canada while tailing off in New England, raising questions about what the valuable shellfish’s population will look like in several years.

University of Maine scientist Rick Wahle has documented trends in baby lobster density for years, and released new data for 2018 this month. The new data reinforce recent trends about lobsters that show upticks off sites in Atlantic Canada, such as some areas in Nova Scotia, Wahle said. Meanwhile, the Gulf of Maine reported below average numbers from Bar Harbor to Cape Cod, he said.

American fishermen compete with Canada for the same species of lobster, which anchors one of the most lucrative fisheries in either country. Some scientists have said the shellfish appear to be moving north as waters warm. “It’s as if this wave that has crested in Maine is now increasing in Atlantic Canada,” Wahle said.

New England’s commercial harvest of lobster has been strong in recent years, but it’s dependent on young lobsters growing to maturity. Some New England sites, such as those off Rhode Island, show few baby lobsters at all.
