Waters Off California Acidifying Faster Than Rest of Oceans, Study Shows

December 17, 2019 — California’s coastal waters are acidifying twice as fast as the rest of the oceans, a study published Monday shows. And some of California’s most important seafood — including the spiny lobster, the market squid and the Dungeness crab — are becoming increasingly vulnerable.

The carbon dioxide emissions that contribute to the planet’s rapidly warming climate are also changing the chemistry of the world’s oceans, which have absorbed roughly 27 percent of the carbon dioxide emitted worldwide.

Ocean water is ordinarily slightly basic, or alkaline, but is becoming more acidic as it absorbs carbon dioxide. This can harm marine life, especially shellfish, because they struggle to make their shells in acidic waters.

Emily Osborne, a scientist in the National Oceanic and Atmospheric Administration’s ocean acidification program, with her colleagues studied the fossil record of planktonic foraminifera — tiny simple organisms which, like shellfish, build their shells from calcium carbonate. They have been around for millions of years, but each individual organism only lives for roughly a month.

2025 global salmon growth forecasts overestimated, new paper argues

December 17, 2019 — Global salmon growth forecasts to 2025 could be overestimated by 6 to 8 percent, according to a new briefing paper from financial think tank Planet Tracker. The culprit is global warming, the paper argues.

In “Salmon Feels the Heat,” researchers analysed reported fish losses attributed to recurring environmental shocks over the past nine years, as reported by the 10 largest publicly listed salmon producers in Norway, Chile, and the United Kingdom. They found that the aggregated production and earnings losses relative to forecast production reached 5 percent for the period between 2010 to 2019.

Fishermen get scant mention in ‘Blue New Deal’

December 16, 2019 — We here at FishOn are simple folk and we live by some pretty simple rules. Rule No. 1 is why stand when you can sit. Rule No. 2 is that any meeting that lasts more than 15 minutes and involves more than three people generally is a colossal waste of time for everyone.

The same principle, of course, can be applied to the various pledges, promises and plans issued by anyone running for elective office. And that brings us to our own Sen. Elizabeth Warren and her seemingly bottomless capacity, in her quest for the presidency, for issuing plans to cure everything but the common cold.

Warren’s campaign last week released its most recent plan — a Blue New Deal for Our Oceans — and let’s just say this is not the most fishing-friendly document on the shelf.

The 15-page document touches on many issues. It addresses expanding offshore renewable energy and building climate-ready fisheries. It talks about expanding community-based seafood markets and investing in regenerative ocean farming and building climate-smart ports.

It urges the protection of ocean habitats and the restoration of marine ecosystems. It calls for the end of offshore drilling and makes the case for that old environmental crowd-pleaser, expanding protected marine areas that would be closed to commercial fishing.

And on and on and on. It’s a Utah lake. About a mile wide and an inch deep.

But nowhere in those thousands of words spread across 15 pages does the plan directly address the plight of the commercial fishing industry and the fishermen who have as much at stake in the blue economy as anyone.

A ‘Strange’ New England Coral May Hold Secrets To Combating Climate Change

December 13, 2019 — When we think about animals that inhabit the cold New England ocean, sharks, seals, or lobsters may spring to mind. But there’s another critter lurking in the deep off our coast, and it’s one that may hold valuable secrets that could help its tropical cousins.

And you may not have even known that it’s actually an animal: coral.

“The coral that exists in Connecticut is called Astrangia poculata,” said Sean Grace, a biologist at Southern Connecticut State University. Grace said the name Astrangia captures the surprise scientists felt when they observed this coral centuries ago.

“You can imagine back then, they pulled it up and looked at it and went, ‘Well, that’s a strange thing to see off the coast of New Jersey, the mid-Atlantic,’” Grace said.

Today this species of Astrangia, also known as the “northern star coral,” is dispersed widely. From southern New England, it goes down the Eastern Seaboard into the Gulf of Mexico.

Corals are invertebrates. They’re not plants. They’re definitely not rocks. Instead, corals are related to jellyfish and anemones.

The Blob returns: Alaska cod fishery closes for 2020

December 11, 2019 — The Gulf of Alaska’s federal cod fleet is bracing for a complete shutdown in 2020 after an 80 percent TAC cut in 2018 and another 5 percent last year, down to 17,000 tons.

The North Pacific Fishery Management Council announced its decision on Friday, Dec. 6, in response to low recruitment.

“We’re on the knife’s edge of this overfished status,” said Council Member Nicole Kimball, vice president of Alaskan operations for the Pacific Seafood Processors Association.

The fall 2019 stock assessment returned biomass numbers for gulf cod below the necessary threshold as a food source for the endangered Steller sea lion.

The infamous Blob of 2014 — a mass of warm water that hovered in the Gulf of Alaska — likely depleted the cod’s food supply and severely restricted recruitment. The fall 2017 Gulf of Alaska survey yielded historically low numbers at 46,080 metric tons, down more than 80 percent since 2013.

“That warm water was sitting in the gulf for three years starting in 2014, and it was different than other years in that it went really deep and it also lasted throughout the winter,” said Steven Barbeaux with the Alaska Fisheries Science Center in Seattle. “You can deplete the food source pretty rapidly when the entire ecosystem is ramped up in those warm temperatures.”

Climate Change Hitting Top U.S. Fishery in the Arctic: NOAA

December 11, 2019 — Climate change is causing chaos in the Bering Sea, home to one of America’s largest fisheries, an example of how rising temperatures can rapidly change ecosystems important to the economy, U.S. federal government scientists said in a report on Tuesday.

Rising temperatures in the Arctic have led to decreases in sea ice, record warm temperatures at the bottom of the Bering Sea and the northward migration of fish species such as Pacific cod, the U.S. National Oceanic and Atmospheric Administration, or NOAA, said in its 2019 Arctic Report Card.

While the changes are widespread in the Arctic, the effect on wildlife is acute in the eastern shelf of the Bering Sea, which yields more than 40% of the annual U.S. fish and shellfish catch.

“The changes going on have the potential to influence the kinds of fish products you have available to you, whether that’s fish sticks in the grocery store or shellfish at a restaurant,” said Rick Thoman, a meteorologist in Alaska and one of the report’s authors.

‘Climate shocks’ reducing fish stocks in New England, and Atlantic Canada could be next

December 11, 2019 — A new study says “climate shocks” are reducing fish populations in the North Atlantic region, leading to fewer jobs and lower wages in New England’s fishing sector.

Fishing communities along the northeastern U.S. seaboard have long struggled with warming waters, dwindling fish stocks and rising unemployment.

The research published Monday in the Proceedings of the National Academy of Sciences is the first to directly link climate change with declining fishing jobs.

It found that climate fluctuations caused a 16 per cent drop in fisheries employment in New England from 1996 to 2017.

The findings suggest Atlantic Canada’s fisheries could also potentially experience increasing variability in fish stocks, revenue and employment due to climate change in the coming years.

New England fishermen losing jobs due to climate fluctuations

December 11, 2019 — For decades the biggest threat to the industry has been overfishing, but it is no longer the only threat. According to new research at the University of Delaware, fluctuations in the climate have already cost some New England fishermen their jobs.

UD’s Kimberly Oremus, assistant professor of marine policy, makes the direct link, for the first time, between large-scale climate variability and fishing job losses in a study published Dec. 9 in the Proceedings of the National Academy of Sciences.

By correlating the North Atlantic Oscillation (NAO) — New England’s dominant climate signal — with labor numbers, Oremus determined that New England’s coastal counties have, on average, lost 16% of their fishing jobs due to climate variation from 1996 to 2017.

This specific effect of climate is distinct from the overall job losses and gains caused by other factors, such as changes in market demand, regulatory changes to curb overfishing, and broader economic trends. Currently, 34,000 commercial marine fishermen are employed in New England’s industry.

“As we see more warm winters off the New England coast, historic fisheries decline and fewer fishermen stay in business,” Oremus said. “This has important implications for fisheries management in New England, which employs 20% of U.S. commercial harvesters.”

Warren releases ‘Blue New Deal,’ a plan to help ailing oceans

December 10, 2019 — Senator Elizabeth Warren on Tuesday released an addendum to her vision for a Green New Deal: the Blue New Deal.

The new plan seeks to address how climate change is affecting oceans and other waters, while ensuring a vibrant marine economy, she said.

“While the ocean is severely threatened, it can also be a major part of the climate solution,” she wrote in a nine-page summary of the plan. “That is why I believe that a Blue New Deal must be an essential part of any Green New Deal.”

“Not being consulted on this isn’t a good start to the relationship,” said Drew Minkiewicz, an attorney for the Fisheries Survival Fund in Washington, D.C., which represents the scallop industry. “We expected something more well-thought-out from her.”

Annie Hawkins, executive director of the Responsible Offshore Development Alliance, a coalition of fishing industry associations and companies, said that “any large industrial project in the ocean will have significant impacts to the sustainability of established activities and the marine environment.”

“To me, it seems like it was written by staff, and they did a lot of Googling,” said Robert Vanasse, executive director of Saving Seafood, a Washington-based group that represents commercial fishermen. “It’s disappointing, because we know Senator Warren has a more sophisticated understanding of fisheries.”

Runaway warming could sink fishing and reef tourism, researchers warn

December 9, 2019 — Countries from Egypt to Mexico could lose 95% of their income from coral reef tourism, and parts of West Africa could see their ocean fisheries decline by 85% by the turn of the century if planet-warming emissions continue to rise, oceans experts warned Friday.

“Action in reducing emissions really needs to be taken, or we will be facing very important impacts” on oceans and people, said Elena Ojea, one of the authors of a new paper looking at the potential impacts of climate change on ocean economies.

The study, released at the U.N. climate negotiations in Madrid, was commissioned by the leaders of 14 countries with ocean-dependent economies, and looked at ocean fisheries and seafood cultivation industries, and coral reef tourism.

It found that reef tourism, a nearly $36-billion-a-year industry today, could see more than 90% losses globally by 2100 under a high-emissions scenario.

Countries particularly dependent on coral reef tourism – Egypt, Indonesia, Mexico, Thailand and Australia – could see income cut by 95%, the paper noted.

Ove Hoegh-Guldberg, an ocean expert at Australia’s University of Queensland and one of paper’s authors, said his country’s Great Barrier Reef tourism industry – worth billions a year a year – was already seeing losses as corals bleached and died.
