May 20, 2013 — Fishing is a profession often passed down from one generation to the next. Many lobstermen in Maine fish the same bottom their fathers and grandfathers fished, and the same holds true of fishermen father offshore as well. Yet increasingly, anecdotal evidence has suggested that the old faithful fishing spots are no longer quite so reliable.
In northern regions these shifts could lead to conflicts over fishing rights and access to traditional fishing grounds. In the tropics, the problem could be more dire. As our oceans warm, species may not be able to adapt at all, leaving tropical oceans with severely depleted fish stocks and some of the most vulnerable human populations with a distinct shortage of a vital protein source.
Much of this scarcity of native species can be attributed to overfishing, a practice now largely halted in U.S. waters thanks to strict new science-based management tactics implemented as a result of a 2006 reauthorization of the law that governs our fisheries. But increasingly, both scientists and fishermen have been eying climate change as a reason some fish are showing up in new places and the catch fishermen are accustomed to finding have been surprisingly slow to rebuild.
