Marine Scientist Follows Hot Fish as They Move to Cooler Waters

November 30, 2016 — Warming oceans have fish on the move, and one man is in hot pursuit.

That man, Rutgers University marine biologist Malin Pinsky, has tracked fish species all over North American waters to learn where they’re headed in search of cooler conditions.

Recently, he’s seen lobsters nearly disappear from Long Island Sound, driven out by disease and a series of warm summers. The delicacies are thriving in the cooler Gulf of Maine, but that may be temporary: Water temperatures there are rising faster than anywhere else in the North Atlantic. Pinsky has also observed Black sea bass, traditionally plentiful off Virginia, start to relocate to the Gulf of Maine and the waters off the New Jersey coast. And out west, Pacific halibut and arrowtooth flounder in the eastern Bering Sea off Alaska have shifted north toward the Arctic.

“It’s not one species in one place or a few species in a limited area,” Pinsky says of the moving populations. “It’s actually hundreds of species in North America shifting toward cooler waters, and that’s significant.”

The changes pose major questions for fishermen and fishery managers. As species move, will fishermen relocate their businesses to follow? How do fishery managers set rules when fish have moved to new areas where they may be more susceptible to overfishing? And will species such as lionfish, which are invasive in the Atlantic Ocean and thrive in warm Southern waters, suddenly appear in force farther north along the Atlantic coast? Even more confounding is the effect of temperature changes on species such as corals that have difficulty relocating to a more suitable place.

ALASKA: Council convenes in Kodiak with Gulf catch shares in focus

June 2, 2016 — The North Pacific Fishery Management Council will meet in Kodiak from June 6-14 to hear a discussion paper that has enraged the trawl industry since late 2015.

Two proposals are engineered to prevent harmful impacts such as the job losses and high cost of entry that have occurred under previous such programs in halibut and crab.

This is an official state position, and the North Pacific council holds a six-member majority of the 11-member body that governs federal Alaska waters.

Gov. Bill Walker’s administration prioritizes coastal communities’ economic prospects during the state’s oil-driven financial calamity. Part of that stance concerns keeping the fishing industry, the state’s largest private employer, in Alaskan fishermen’s hands.

“The greatest challenge facing fishery managers and communities to date has been how to adequately protect communities and working fishermen from the effects of fisheries privatization, notably excessive consolidation and concentration of fishing privileges, crew job loss, rising entry costs, absentee ownership of quota and high leasing fees, and the flight of fishing rights and wealth from fishery dependent communities,” the council’s discussion paper reads. “Collectively, these impacts are altering and in some cases severing the connection between Alaska coastal communities and fisheries.”

For years, the council has mulled over a regulations to install catch shares in the Gulf of Alaska groundfish fisheries. Mainly trawlers go after this fishery, which includes pollock, a midwater fish, and species such as Pacific cod and arrowtooth flounder, which are bottom, or pelagic, fish.
