Saving Seafood

Does fishing have a future in New England?

December 22, 2015 — Cod have been disappearing from the waters between Massachusetts and Maine, and shrimp populations are so depleted that the commercial shrimp season in the Gulf of Maine has been cancelled for the last three years.

At the same time, lobster are flourishing — alongside a host of species that have never before thrived in New England waters.

Why the wild ups and downs? One reason is that nearby waters are warming much faster than the rest of the ocean, making the environment newly unbearable for some longtime residents — and newly appealing for others. But overfishing has played a role as well, disrupting the balance of the watery ecosystem in unexpected ways.

It’s hard to predict where all this is headed, whether for individual species or local fishing communities. But it needn’t be a story of doom and gloom. These undersea changes may well dampen the prospects of the cod industry, but they will also bring new opportunities.

What’s happening in nearby waters?

Rapid and unusual warming.

Temperatures in the Gulf of Maine have been increasing faster than just about every other blue spot on the planet. According to a recent report in Science, Maine’s waters are in the top 0.1 percent when it comes to rapid warming.

While that team focused on the waters to the east and north of Massachusetts, that superwarm area they reported on actually extends significantly south, surrounding the Bay State.

How whaling logs from the 1800s might help us solve climate change

December 16, 2015 — NEW BEDFORD, Mass. — Maritime historians, climate scientists and ordinary citizens are coming together on a project to study the logbooks of 19th-century whaling ships to better understand modern-day climate change and Arctic weather patterns.

Whaling ships kept meticulous daily logbooks of weather conditions during their often yearslong voyages searching the globe for whales, valued for their light-giving oil, said Michael Dyer, senior maritime historian at the New Bedford Whaling Museum, which is supplying much of the data.

Some logs include information about life on board, such as sailors falling overboard, or being disciplined for stealing or other transgressions, and of course, notations whenever whales are spotted. More important for this project, they include precise longitude and latitude measurements, weather conditions, the presence of icebergs and the edge of the ice shelf.

“If they’re cruising in the Bering Strait and there’s ice, there will be a notation in the logbook that ice fields are present,” Dyer said.

The project, called Old Weather: Whaling, is led by the National Oceanic and Atmospheric Administration. The whaling museum is transcribing and digitizing its own logbooks, as well as original data sources from the Nantucket Historical Association, Martha’s Vineyard Museum, Mystic Seaport in Connecticut, and the New Bedford Free Public Library.“If they’re cruising in the Bering Strait and there’s ice, there will be a notation in the logbook that ice fields are present,” Dyer said.

Fish Stocks Are Declining Worldwide, And Climate Change Is On The Hook

December 14, 2015 — For anyone paying attention, it’s no secret there’s a lot of weird stuff going on in the oceans right now. We’ve got a monster El Nino looming in the Pacific. Ocean acidification is prompting hand wringing among oyster lovers. Migrating fish populations have caused tensions between countries over fishing rights. And fishermen say they’re seeing unusual patterns in fish stocks they haven’t seen before.

Researchers now have more grim news to add to the mix. An analysis published Monday in the Proceedings of the National Academy of Sciences finds that the ability of fish populations to reproduce and replenish themselves is declining across the globe.

“This, as far as we know, is the first global-scale study that documents the actual productivity of fish stocks is in decline,” says lead author Gregory L. Britten, a doctoral student at the University of California, Irvine.

Britten and some fellow researchers looked at data from a global database of 262 commercial fish stocks in dozens of large marine ecosystems across the globe. They say they’ve identified a pattern of decline in juvenile fish (young fish that have not yet reached reproductive age) that is closely tied to a decline in the amount of phytoplankton, or microalgae, in the water.

Baby fish will be lost at sea in acidified oceans

December 15, 2015 — The ability of baby fish to find a home, or other safe haven, to grow into adulthood will be severely impacted under predicted ocean acidification, University of Adelaide research has found. 

Published today in the journal Proceedings of the Royal Society B, the researchers report the interpretation of normal ocean sound cues which help baby fish find an appropriate home is completely confused under the levels of CO2 predicted to be found in oceans by the end of the century.

“Locating appropriate homes is a crucial step in the life cycle of fish,” says Tullio Rossi, PhD candidate with the University’s Environment Institute. “After hatching in the open ocean, baby fish travel to reefs or mangroves as safe havens to feed and grow into adults.

“Baby fish can find those places through ocean noise: snapping shrimps and other creatures produce sounds that the baby fish follow.

“But when ocean acidity increases due to increased CO2, the neurological pathways in their brain are affected and, instead of heading towards those sounds, they turn tail and swim away.”

NOAA Awards Funding for Research Projects to Study Climate Impacts on Fish and Fisheries

December 15, 2015 — The following was released by NOAA Fisheries:

Seven projects to increase understanding and response to climate-related impacts on living marine resources

Following release of the  NOAA Fisheries Climate Science Strategy, today the agency announced $5 million in new research funding to study the impacts of climate change on fish and fisheries of the Northeast Shelf Large Marine Ecosystem. The funds, which will be distributed over the next two to three years, will support seven new projects designed to increase our understanding of how climate change can affect fish stocks, fisheries, and the communities that depend on them for their livelihood.

“Warmer coastal and ocean waters and ocean acidification are already affecting our nation’s fisheries,” said NOAA Fisheries chief science advisor Richard Merrick, Ph.D. “NOAA is working to ensure the resilience of healthy, productive fisheries that are essential to U.S. coastal communities. Sustainable fisheries create jobs, stabilize coastal economies, enhance commerce, and help to meet the growing demand for seafood.” 

NOAA Research’s Climate Program Office and NOAA Fisheries Office of Science and Technology funded the projects through a competitive process and include collaborations between NOAA and academic scientists. In addition, these projects support the Administration’s Priority Agenda for Enhancing the Climate Resiliency of America’s Natural Resources.

Six projects support research to understand and respond to climate impacts on fish and fisheries in the Northeast Shelf Large Marine Ecosystem and the seventh will support a workshop focused on ecosystem tipping points in the North Pacific.

Finding Refuge for Salmon, Cold Water Preferred

December 11, 2015 — PORTLAND, Ore. — When Lewis and Clark first encountered the Columbia River in 1805, they wrote about nearby streams so thick with salmon that you could all but walk across on their backs.

Last summer, those streams looked very different. As a torrid heat wave settled over the Pacific Northwest, the salmon heading up the Columbia River from the ocean in their ancient reproduction ritual started dying en masse, cooked in place by freakishly hot water that killed them or made them vulnerable to predators. Sockeye died by the hundreds of thousands.

“It was a peek at the future,” said Jim Martin, a former chief of fisheries for Oregon, who now works on conservation issues for a fishing tackle company, Pure Fishing. “This is exactly what is predicted by climate-change models.”

Other salmon experts, though, said the future was not that clear. Even as the sockeye here were dying, they said, pink salmon were exploding in number, especially in the Puget Sound area around Seattle. Alaska, which actually supplies most of the wild-caught salmon eaten in Portland, Seattle and other coastal cities that have their identities tied to fish, had its own good-news story this year, with a near-record harvest.

Warmer waters affecting the New England fishing industry

December 9, 2015 — A new study has found the Gulf of Maine is warming faster than almost every other ocean in the world. For the first time, it links warming sea temperatures to the collapse of cod stocks in the region.

For Portland’s fishing community, the first hours of daylight are the most important. At the town’s fish exchange, boats rush to unload their catch, ready to be sorted, and sold.

They are not just working against time.

Today’s landing at the Portland fish exchange was about 40,000 pounds worth. That’s not considered very much. Out of that, just seven boxes worth of cod; that’s about 500 pounds.”

Cod stocks have been declining here for decades. Federal quotas were slashed by 75 percent back in May, to help the species recover.

Now a new study suggests that intervention may have been too late.

Andrew Pershing, chief scientific officer at the Gulf of Maine Research Institute says, “You assume that if you pull back on the fishing, the stock will have the same productivity that it had in the past.  But our work really shows that the productivity in Gulf of Maine cod was declining pretty rapidly as the waters were getting warm and so by not factoring that in they weren’t able to rein in the quotas fast enough.”

Moratorium on Northern Shrimp Commercial Fishing Maintained for 2016 Season

December 8, 2015 — PORTSMOUTH, N.H. – The following was released by the Atlantic States Marine Fisheries Commission:

In response to the depleted condition of the northern shrimp resource, the Atlantic States Marine Fisheries Commission’s Northern Shrimp Section extended the moratorium on commercial fishing for the 2016 fishing season. The 2015 Stock Status Report for Gulf of Maine (GOM) Northern Shrimp indicates abundance and biomass indices for 2012-2015 were the lowest on record for the 32-year time series. The stock has experience failed recruitment for five consecutive years, including the three smallest year classes on record. As a result, the indices of fishable biomass from 2012-2015 are the lowest on record. 

Recruitment of northern shrimp is related to both spawning biomass and ocean temperatures, with higher spawning biomass and colder temperatures producing stronger recruitment. Ocean temperatures in western GOM shrimp habitat have increased over the past decade and reached unprecedented highs in 2011 and 2012. While 2014 and 2015 temperatures were cooler, temperatures are predicted to continue to rise as a result of climate change. This suggests an increasingly inhospitable environment for northern shrimp. The Northern Shrimp Technical Committee considers the stock to have collapsed with little prospect of recovery in the immediate future. The 2015 Stock Status Report is available at http://www.asmfc.org/uploads/file/5666017a2015NorthernShrimpAssessment.pdf. 

To maintain the time series of data collected from northern shrimp commercial fishery catches, a cooperative winter sampling program was approved with a 22 metric ton research set aside quota. The goal of the program is to continue the winter time series of biological data (e.g. size composition, egg hatch timing) collected from GOM northern shrimp fishery catches in the absence of a fishery.  Four trawl vessels will be contracted to fish four regions with a maximum trip limit of 1,800 pounds, and two trappers with a weekly trap limit of 40 traps and a 600 pound per week limit. Participating trawlers and trappers will be able to sell their catch.  Trawlers will also be compensated $500/trip. 

“Considering survey indices are the lowest on record, with an unprecedented five consecutive years of weak recruitment and continuing unfavorable environmental conditions, the Section maintained the moratorium in 2016,” stated Northern Shrimp Section Chair Mike Armstrong of Massachusetts. “The Section is committed to protecting the remaining spawning biomass and allowing as much reproduction to take place as possible.”
