Multiple Fish Species Moving North, Deeper To Avoid Warming Water; Fishery Rules Play Catch-Up
POINT JUDITH, R.I. — There was a time when whiting were plentiful in the waters of Rhode Island Sound, and Christopher Brown pulled the fish into his long stern trawler by the bucketful. “We used to come right here and catch two, three, four thousand pounds a day, sometimes 10,” he said, sitting at the wheel of the Proud Mary — a 44-footer named, he said, after his wife, not the Creedence Clearwater Revival song — as it cruised out to sea.
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.
EDIT
The center of the black sea bass population, for example, is now in New Jersey, hundreds of miles north of where it was in the 1990s, providing the basis for regulators to distribute shares of the catch to the Atlantic states. Under those rules, North Carolina still has rights to the largest share. The result is a convoluted workaround many fishermen view as nonsensical. Because black sea bass are now harder to find in their state waters, North Carolina fishermen must steam north 10 hours, to where the fish are abundant, to even approach the state’s allocation. Mr. Brown and other New England fishermen, however, whose states have much smaller shares, can legally land only a small fraction of the black sea bass they catch and must throw the rest overboard. And New England states like Maine, where fishermen are beginning to catch black sea bass regularly, have only a tiny allocation and no established fishery.
