West Coast Waters Returning to Normal; Some Fisheries Remain Disrupted

March 13, 2018 — SEAFOOD NEWS — Ocean conditions off most of the U.S. West Coast are returning roughly to average, after an extreme marine heat wave from about 2014 to 2016 disrupted the California Current Ecosystem and shifted many species beyond their traditional range, according to a new report from NOAA Fisheries’ two marine laboratories on the West Coast. Some warm waters remain off the Pacific Northwest, however.

The Southwest Fisheries Science Center and Northwest Fisheries Science Center presented their annual “California Current Ecosystem Status Report” to the Pacific Fishery Management Council at the Council’s meeting in Rohnert Park, Calif., on Friday, March 9. The California Current encompasses the entire West Coast marine ecosystem, and the report informs the Council about conditions and trends in the ecosystem that may affect marine species and fishing in the coming year.

“The report gives us an important glimpse at what the science is saying about the species and resources that we manage and rely on in terms of our West Coast economy,” Council Chairman Phil Anderson, of Westport, Wash., said in a press release. “The point is that we want to be as informed as we can be when we make decisions that affect those species, and this report helps us do that.”

Unusually warm ocean temperatures, referred to as “the Blob,” encompassed much of the West Coast beginning about 2014, combining with an especially strong El Nino pattern in 2015. The warm conditions have now waned, although some after-effects remain.

Warmer waters were blamed for increased growth of Pseudo nitzschia, which produces domoic acid. The domoic acid interrupted several fisheries, including Dungeness crab, rock crab and spiny lobster.

Warm Pacific Ocean ‘blob’ facilitated vast toxic algae bloom

September 30, 2016 –SEATTLE — A new study finds that unusually warm Pacific Ocean temperatures helped cause a massive bloom of toxic algae last year that closed lucrative fisheries from California to British Columbia and disrupted marine life from seabirds to sea lions.

Scientists linked the large patch of warm ocean water, nicknamed the “blob,” to the vast ribbon of toxic algae that flourished in 2015 and produced record-breaking levels of a neurotoxin that is harmful to people, fish and marine life.

The outbreak of the toxin domoic acid, the largest ever recorded on the West Coast, closed razor clam seasons in Washington and Oregon and delayed lucrative Dungeness crab fisheries along the coast. High levels were also detected in many stranded marine mammals.

“We’re not surprised now having looked at the data, but our study is the first to demonstrate that linkage,” said Ryan McCabe, lead author and a research scientist at the University of Washington’s Joint Institute for the Study of the Atmosphere and Ocean. “It’s the first question that everyone was asking.”

El Niño is Going to Starve a Lot of Fish

October 14, 2015 — When Joe Orsi goes trawling, he doesn’t go trawling for 900-pound ocean sunfish. Orsi’s title is biologist, his employer the NOAA Alaska Fisheries Research Center, his cause researching said state’s fisheries. His typical prey, therefore, are juvenile Alaskan salmon. Sunfish are tropical—occasionally temperate—creatures, and do not belong about 40 miles offshore of a place called Icy Point. But that’s what Orsi’s nets brought up in June.

“What’s crazy is, like a day before, a guy asked me what was the strangest thing I’d brought up in a trawl,” says Orsi. Whatever he answered then—sea otter, Dall’s porpoise, maybe a blue shark—is certainly obsolete now.

Strange things are aswim along the Pacific coast. Starving sea lion pups, jellyfish swarms, toxic algae blooms. All because of an enormous mass of warm water stretching from California to Alaska that scientists have dubbed “the Blob.” And the Blob is about to get joined by more warm water from the gargantuan El Niño—with its own scientific nickname, “Godzilla“—forming in the equatorial east Pacific. When these monster warm water systems eventually meet, they aren’t just going to bring charming equatorial fish on subarctic vacations. They’re probably going to deliver a generation (or several generations) of scrawny fish to the oceans.
