January 23, 2017 — There’s long been an undercurrent of mistrust between fishermen who make their livelihoods from the Gulf of Maine and the scientists whose surveys and calculations determine the amount of fish they can catch.
That, in part, is because it can seem as if fishermen and scientists are talking about two different Gulfs of Maine when they discuss the size of the cod population.
Scientists document a groundfish stock in perpetual decline with an outlook that doesn’t seem to have changed much in response to increasingly restrictive limits on the amount fishermen can catch. They note a species that has struggled to recover after more than a century of overfishing and now faces the added challenge of rebuilding in an area of the ocean that’s warming faster than 99 percent of the rest of the world’s oceans. Indeed, researchers from the Gulf of Maine Research Institute, the University of Maine and elsewhere have found that warming waters reduce the number of new cod produced by spawning females and reduce the likelihood that young fish will survive to adulthood.
Fishermen, meanwhile, report something different.
“This is uncalled for,” Joseph Orlando, a cod fisherman who fishes off the coast of Gloucester, Massachusetts, told NPR in 2014 after regulators cut the Gulf of Maine cod fishing season short that year. “There’s more codfish out there. There’s always been.”
