January 24, 2018 — Is the lobster boom on the decline in the Gulf of Maine because of warming waters? A newly released study by a Maine-based marine research group suggests that is the case.
The study, released Monday by the Gulf of Maine Research Institute, touched on many of the same climate issues that have left researchers and lobster stakeholders anxious about the future.
“In the Gulf of Maine, the lobster fishery is vulnerable to future temperature increases,” GMRI said in the statement released with the study. “The researchers’ population projections suggest that lobster productivity will decrease as temperatures continue to warm, but continued conservation efforts can mitigate the impacts of future warming.”
The study, compiled with the University of Maine and NOAA Fisheries, said the anticipated decline highlights the need for vigilant conservation within the Gulf of Maine lobster fishery, especially since scientists say the gulf’s waters are warming faster than 99 percent of the rest of the world’s oceans.
Researchers said they expect the lobster population to decline from recent highs — GMRI pegs the peak year at 2010, when it estimated the Gulf of Maine lobster stock contained 518 million lobsters — to levels more in keeping with traditional lobstering years.
It estimates the population could shrink to about 261 million lobsters in 2050.
“The 30-year outlook for the Gulf of Maine fishery looks positive if conservation practices continue,” GMRI said. “In their 30-year projection, the researchers anticipate average populations similar to those in the early 2000s.”
Beth Casoni, executive director of the Massachusetts Lobstermen’s Association, said lobster stock assessments in the Gulf of Maine have shown the annual settlement of young lobsters — when they transition from floating in open waters as plankton to settling on the bottom to begin the seven- to eight-year stretch it requires to mature — has declined from previous assessments.
