March 1, 2019 — In 1997, large commercial fishing boats based in the coastal town of Beaufort, North Carolina began shifting about 13 miles northward per year. By the end of 2014, they were harvesting off the coast of New Jersey. Although this was an unusual circumstance, it wasn’t singular. As it turns out, many large-scale fishing operations along the East Coast followed similar patterns of movement within that time frame. These shifts will persist or even intensify if climate change continues to warm up our oceans, according to new research published in the latest issue of ICES Journal of Marine Science.
In the past century, global warming has gradually raised the temperature of water along the Atlantic seaboard. Like moneyed New Yorkers taking to the Hamptons to escape city heat, fish close to the coastline are swimming away from their usual marine homes and toward cooler and more comfortable waters. As a result, fishing operations are getting disrupted. While the stories of fishers who have to travel longer and longer distances to secure their catch are well documented, the movements of fishing communities over time have not been mapped until now.
Talia Young, a postdoctoral fellow at Princeton University, conducted the first-of-its-kind ICES study in part because she wanted to bridge what she felt was a disconnect between the empirical data of marine species migration and its impact on humans.
