Save our lobster rolls!

Curt Brown spent his childhood harvesting lobsters along the coast of Maine. As an adult, he went on to earn a Master of Science from the University of Maine, observing the very waters where he spent years fishing for the crustaceans.
With a rapidly changing climate, many researchers worry that Maine’s lobsters will eventually move north to colder waters. Brown isn’t so sure, though, seeing all of the forces affecting the ecosystem as highly complex. His studies in marine biology and policy, along with his continued work as a lobsterman, have helped him understand that the lobster industry depends upon various factors, some beyond man’s control.
Last year, the state of Maine’s lobster fisheries harvested 78.8 million pounds of lobsters, and according to the Maine Department of Marine Resources (DMR), commercial harvesters earned $619 million.
Synonymous with the New England state, lobsters have a documented history in Maine that dates back to 1605. Recent studies, though, show that climate change and a shift in currents are warming up the local waters. In a now well-quoted 2015 study led by Andrew Pershing, researchers found that the surface temperature of the Gulf of Maine is warming 99 percent faster than the rest of the ocean.
Some say this could lead to lobsters moving north to Canadian waters in search of colder temperatures and many wonder what the future of Maine’s fishery will look like.
Brown feels like the rate of warming has been sensationalized as a headline since the Pershing’s study came out, and sees the issues facing lobsters more nuanced and complex.
An October study funded by NOAA National Sea Grant’s American Lobster Initiative looks at the effects that multiple stressors, not just warming waters, have on lobster embryos and their future life cycles.
In the study, “Effects of multiple stressors on embryos and emerging larvae of the American lobster,” researchers look at how the combination of warming waters and ocean acidification affect egg-bearing lobsters and the development and physiology of their embryos in the hopes of getting a more accurate picture of what the future of Maine’s lobster fishery may look like as the effects of human-caused climate change increase.
