Climate change preview Pacific Ocean blob appears to take toll on Alaska cod. Warm water linked to the blob appears to have knocked back Gulf of Alaska cod. Fishing fleets, many based in Washington, are bracing for cuts. Gulf of Alaska cod populations appear to have nose dived, a collapse fishery scientists believe is linked to warm water temperatures known as the blob that peaked in 2. The decline is expected to substantially reduce the Gulf cod harvests that in recent years have been worth before processing more than 5. Northwest and Alaska fishermen who catch them with nets, pot traps and baited hooks set along the sea bottom. The blob also could foreshadow the effects of climate change on the marine ecosystem off Alaskas coast, where chilly waters rich with food sustain North Americas richest fisheries. Federal fisheries biologist Steve Barbeaux says that the warm water, which has spread to depths of more than 1,0. Higher temperatures sped up the rate at which young cod burned calories while reducing the food available for the cod to consume. They get weak and die or get eaten by something else, said Barbeaux, who in October presented preliminary survey findings to scientists and industry officials at an Anchorage meeting of the North Pacific Fishery Management Council.

Barbeaux said the cod decline likely resulted from the blob, a huge influx of warm Pacific Ocean water that stretched during its 2. Gulf of Alaska to Californias offshore waters. Biologists tracked increases in bird die offs, whale strandings and other events such as toxic algae blooms. Even today, its effects appear to linger, such as in the dismal survey results for salmon this past summer off Oregon and Washington. Scientists dont ascribe the blob specifically to climate change. Gulf of Alaska temperatures influenced by atmospheric conditions such as wind strengths have always fluctuated over time.

But researchers have never before tracked such an extreme heat wave that spread across such distances and penetrated to such depths. And the blob, though now easing, is likely a preview of ocean temperatures expected later in the century as climate change intensifies. Climate scientists note that ocean temperatures are on the rise as the water absorbs most of the heat trapped by greenhouse gases in the atmosphere. Another major concern has been the effects of ocean acidification, as the water absorbs carbon dioxide from fossil fuel emissions. In Alaska, that is expected to create problems for crab. The blob began to take hold in 2. Fahrenheit in some surface waters of the Gulf of Alaska. In deeper waters, where cod feed, the temperature rose by more than 1 degree Fahrenheit. The surface temperatures recorded during the blobs peak could be close to the average at centurys end, according to a report on climate change released last week by the U. S. Global Change Research Program. Thus, future blobs could push temperatures much higher than the most recent event. They may not necessarily be more frequent, but they will be more intense said Nicholas Bond, a University of Washington climate scientist who assisted in the Gulf of Alaska cod research. This is really going to be uncharted territory. Games Psp. For NOAA Fisheries scientists such as the Seattle based Barbeaux, the blobs dramatic effects have become an important part off their research of a changing ocean that absorbs most of the heat from the buildup of greenhouse gases in the atmosphere. Under the Trump administration, NOAA Fisheries scientists have been able to openly post about climate change on agency webpages even as the topic has been purged from many Environmental Protection Agency and Interior Department online sites. Across the United States, changes in our climate and our oceans are having very real and profound effects on communities, businesses, and the natural resources we depend on including our economically valuable fisheries declared a NOAA Fisheries webpage updated in June. Understanding these changes and measuring their impacts is an important part of NOAA Fisheries mission. Scientists are trying to unravel what happened to the Gulf of Alaskas Pacific cod, which yields thick fillets that are a staple of fish and chips.

They are found both in the Gulf of Alaska, and in even larger concentrations farther west, in the Bering Sea. Since cod are coldblooded, their metabolism ramps up and they need to eat more as ocean temperatures climb. Barbeaux calculates that by 2. As the water warmed, the appetites of other coldblooded creatures also increased. Meanwhile, evidence indicates that the higher temperatures reduced the amount of high quality, high fat zooplankton many species feed upon, according to Stephani Zador, a Seattle based federal fisheries scientist. The warm water affected the Bering Sea and the Gulf of Alaska. But the Bering Sea unlike the Gulf has a different ocean ecosystem influenced by the ice pack, and cod stocks there had a smaller decline, according to an initial analysis of a 2.

But by 2. 01. 7, those fish were largely gone for the surveys, which also found scant evidence of fish born in subsequent years. Some fishermen this year also have had a hard time finding Gulf cod. Their total central Gulf of Alaska cod catch with only two months of fishing left lags far below the allowable harvest levels. Many of the cod that have come on board trawlers are long skinny fish that look to have had a hard time finding enough to eat, according to Brent Paine, executive director off United Catcher Boats, an organization of trawl boats that catch Gulf of Alaska cod. This is a big deal, Paine said. We just dont see these cod year classes disappear from one year to the next. Barbeauxs presentation in Anchorage was an early heads up that the cod population appeared to have plummeted in the Gulf. In the weeks ahead, scientists will pore over the survey and other information to come up with a recommended harvest level for the North Pacific Fishery Management Council, which will decide on 2. Bering Sea and Gulf. Fishermen are bracing for cuts, with the only question being how big. The fishermen among the hardest hit by cutbacks work in a largely Puget Sound based fleet of more than 3. If the harvest declines, some boats may end up tied to the dock. That fleet processes and freezes the catch on board, adding to the catch value that in 2. Gulf of Alaska and Bering Sea harvests. Some questions remain about the surveys. Perhaps some cod moved outside the areas that were included in the survey. But a spokesman for the freezer longliners says that overall, he trusts the scientists, whose research has helped keep Alaska fisheries sustainable. What will really define the impacts is whether this is a long term trend, or do the cod bounce back, said Chad See, executive director of the Seattle based Freezer Longline Coalition.
