Lobsters are migrating North along the New England coast at a rate of about 40 mi per decade.Despite the alarmist reports on ocean temperatures using percentages, which can be very misleading, “Data from the US National Oceanic and Atmospheric Administration (NOAA) shows that the average global sea surface temperature – the temperature of the upper few metres of the ocean – has increased by approximately 0.13°C per decade over the past 100 years.”
I cant see how that’s going to convince all those lobsters to hightail it to Canada.
Back when the center of the industry was in Southern New England waters, the Gulf of Maine was too cold to be ideal for lobsters. It's all easy to follow not just in the science but the fishing fleets that migrate as well as the species (and other species). Maine lobstermen are tied to their zones and can't 'migrate' along with the center of the industry.
Lobster like most ocean species are pretty particular about water temperature. A couple degrees might not seem like much. The American lobster prefers water in the 40 to 50F range and dies in water above 68 degrees.
