By Erica Goode, The New York Times. For GSS Climate Change chapter 8.

But like many other fish on the Atlantic Coast, whiting have moved north, seeking cooler waters as ocean temperatures have risen, and they are now filling the nets of fishermen farther up the coast. Studies have found that two-thirds of marine species in the Northeast United States have shifted or extended their range as a result of ocean warming, migrating northward or outward into deeper and cooler water. Lobster, once a staple in southern New England, have decamped to Maine. Black sea bass, scup, yellowtail flounder, mackerel, herring and monkfish, to name just a few species, have all moved to accommodate changing temperatures. Yet fishing regulations, which among other things set legal catch limits for fishermen and are often based on where fish have been most abundant in the past, have failed to keep up with these geographical changes. ...“Our management system assumes that the ocean has white lines drawn on it, but fish don’t see those lines,” said Malin L. Pinsky, an assistant professor in the department of ecology, evolution and natural resources at Rutgers University, who studies how marine species adapt to climate change. “And our management system is not as nimble as the fish.”...  http://www.nytimes.com/2016/12/30/science/fish-climate-change-northeast.html
