In Maine, the lobster fishery is the backbone of the coastal economy—accounting more than for almost three-quarters of the state’s marine-fishery value. But as ocean waters continue to warm, lobster populations may move farther north, creating uncertainty for thousands of livelihoods tied to this single species.
Manomet and partners at Northeastern University and the University of Victoria interviewed lobster fishers in Maine and Massachusetts to document their observations and perceptions of shifting food web dynamics in the Gulf of Maine. Fishers described seeing new species in their traps, noticing shifts in when and where familiar species appear, and grappling with regulations that often prevent them from landing or selling these “new arrivals.” They reported knowledge on over 35 species, as well as complex interactions impacted by warming water and changing species' abundance. This knowledge is invaluable to our understanding of how marine ecosystems are changing and can help inform key management decisions.
