Saving Seafood

Scientists want to use artificial intelligence to save Maine’s coast

October 13, 2021 — Forecasting isn’t just for weather. A new center at Bigelow Laboratory is using cutting-edge artificial intelligence algorithms to forecast ocean activity, from toxic algal blooms to right whale migration, with the hopes of benefitting both coastal industries and the environment.

“There’s a big demand for forecasting. People are expecting forecasts of all different kinds now, from COVID forecasts to political forecasts,” said Nick Record, a senior research scientist at Bigelow Laboratory for Ocean Sciences in East Boothbay. “We’re trying to tap into this societal need and demand for forecasts and apply it to ocean systems that we live in and rely on.”

The ability to accurately forecast complex ocean dynamics alone, such as temperature and salinity, is useful for the industries that use the coastline and the scientists that study it. With artificial intelligence, though, these forecasts will be constantly improving in accuracy even as the climate changes — and, with it, Maine’s ability to adapt to the changing coastline will improve as well.

Maine seeks lease for nation’s first offshore wind research site on federal waters

October 5, 2021 — The state of Maine has applied to lease a little more than 15 square miles of ocean for a floating offshore wind research area in what would be the nation’s first such undertaking in federal waters.

In a 143-page application to the U.S. Department of the Interior’s Bureau of Ocean Management, the Governor’s Energy Office notes that Maine is uniquely qualified to hold the research lease, which will be limited to 12 or fewer turbines located nearly 30 miles offshore.

The distance is meant to avoid nearshore waters valuable to fishing and recreation, in line with the state’s new moratorium on development of offshore wind in state waters. The moratorium was imposed in response to concerns by Maine fishermen about the potential impact of wind projects on their industry.

Securing a lease to conduct research in federal waters will allow the state to use patented technology developed at the University of Maine and help Maine meet long-term climate change goals through wind energy, which represents a $1 trillion opportunity worldwide by 2040, according to the application.

Study Shows Climate Change Could Be Altering the Marine Food Web

September 28, 2021 — Climate change is redistributing biodiversity globally, and distributional shifts of organisms often follow the speed and direction of environmental changes. Research by scientists at Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS) reveals that this phenomenon is affecting where large marine mammals are distributed relative to their prey species, which could have important implications for marine food web dynamics. Their findings are published in Scientific Reports.

Marine mammals (endotherms), such as whales and dolphins, are often assumed to shift their movements and distribution in response to warming waters more slowly than their ectothermic prey, such as fish and squid, whose growth and productivity is directly impacted by water temperature. Since marine mammals are large, highly mobile and occur across wide geographic ranges, distributional shifts in these species are difficult to quantify. In this study, data from fisheries bycatch and stranding events is used to examine changes in the distribution of long-finned pilot whales and their prey relative to climate velocity in a rapidly warming region of the Northwest Atlantic.

Valuable crab populations are in a ‘very scary’ decline in warming Bering Sea

September 22, 2021 — Federal biologist Erin Fedewa boarded a research vessel in June in Dutch Harbor, Alaska, and journeyed to a swath of the Bering Sea that typically yields an abundance of young snow crab in annual surveys.

Not this summer. At this spot, and elsewhere, the sampling nets came up with stunningly few — a more than 99% drop in immature females compared to those found just three years earlier.

Biologists also found significant downturns in the numbers of mature snow crab as they painstakingly sorted through the sea life they hauled up.

“The juveniles obviously were a red flag, but just about every size of snow crab were in dramatic decline,” Fedewa said. “It’s very scary.”

This collapse in the Bering Sea snow crab population comes amid a decade of rapid climatic changes, which have scrambled one of the most productive marine ecosystems on the planet in ways that scientists are just beginning to understand. The changes are forcing them to reconsider how they develop models to forecast harvest seasons.

‘Blue Food Revolution’ to Tackle Climate Change and Malnutrition

September 22, 2021 — Doubling of global demand for aquatic foods calls for a ‘blue food revolution’ to tackle climate change and malnutrition, new research argues.

An unprecedented review of the aquatic foods sector has uncovered how fisheries and aquaculture can play a greater role in delivering healthy diets and more sustainable, equitable and resilient food systems around the world.

Five peer-reviewed papers in the journal Nature highlight the opportunities to leverage the vast diversity of aquatic, or “blue,” foods in the coming decades to address malnutrition, lower the environmental footprint of the food system, and provide livelihoods.

“People are trying to make more informed choices about the food they eat, in particular the environmental footprint of their food,” said Ben Halpern, a marine ecologist at UC Santa Barbara’s Bren School of Environmental Science & Management, who with colleagues examined the environmental sustainability of aquatic foods, the potential for the growth of small-scale producers and the climate risks that face aquatic food systems. “For the first time we pulled together data from hundreds of studies on a wide range of seafood species to help answer that question. Blue foods stack up really well overall and provide a great option for sustainable food.”

The research projects that global demand for blue foods will roughly double by 2050, and will be met primarily through increased aquaculture production rather than by capture fisheries.

Investing in innovation and improving fisheries management could increase consumption even more and have profound effects on malnutrition. For instance, a “high growth” modeling scenario showed that increasing supply by 15.5 million tons (8%), causing a drop in prices, would reduce cases of nutrient deficiencies by 166 million, especially among low-income populations.

US Pacific Fishery Managers Support Climate Change Research to Inform Management Decisions

September 22, 2021 — The Western Pacific Regional Fishery Management Council voted today to approve several plans aimed at improving research and data in the region. The Council’s work relies on robust scientific information for its fishery management decisions. The Council and its advisors developed research priorities with the Pacific Islands Fisheries Science Center, setting the direction for the future.

Climate change is a high priority, in line with the Biden Administration’s efforts to mitigate the impacts and enhance fisheries resilience. Addressing the shift in distribution of stocks and fishing effort due to changes in oceanographic features is a good example.

The Council’s Scientific and Statistical Committee Three-Year Plan focused its priorities on science that directly supports fishery management. A major focus is helping fishing communities to understand the value of data for fishery sustainability.

The Council’s five-year regional research plan is mandated by the Magnuson-Stevens Act. The plan covers research priorities for pelagic and island fisheries, protected species, human communities, cooperative research and management strategy evaluation.

The Council also endorsed the Fishery Data Collection and Research Committee’s strategic plan for 2022 to 2026. The overarching goals of the plan are to:

  • Build local agency capacity to improve fishery-dependent data collection.
  • Provide non-peer-reviewed reports and unpublished datasets.
  • Conduct science and research to support ecosystem-based fishery management.

The Council concluded the first day of its three-day virtual meeting today. The meeting continues tomorrow with decisions on the American Samoa bottomfish rebuilding plan and initial action on seabird mitigation in the Hawai‘i longline fishery. Instructions on connecting to Webex, agendas and briefing documents are posted at www.wpcouncil.org/meetings-calendars.

The Council manages federal fisheries operating in waters offshore of the State of Hawai‘i, the Territories of American Samoa and Guam, the Commonwealth of the Northern Mariana Islands (CNMI) and the U.S. Pacific Remote Islands Areas.

 

Climate Change Scenario Planning: Kick-Off Webinars a Wrap; Input Now Needed on Fishery Impacts via Questionnaire

September 20, 2021 — The following was released by the New England Fishery Management Council:

Climate-related forces such as ocean temperature changes and sea-level rises are certain to shape fisheries on the East Coast between now and 2040. Which forces do you think are most important? What are the unknowns? Do you support exploring how fishery management will be affected by shifting fish stock distributions due to climate-related factors?

These are the kinds of questions being asked as part of the scoping process for the East Coast Climate Change Scenario Planning Initiative. The Core Team overseeing the project recently held three kick-off webinars to introduce fishermen and other stakeholders to climate change scenario planning. Anyone who missed the webinars can watch the videos:

• Introduction to East Coast Climate Change Scenario Planning
• Introduction to Scenario Planning
• Initiative Details
• Process and Participants

The Core Team is now soliciting additional insights, perspectives, and feedback via a questionnaire to help guide future work on this initiative. The 12 questions should take no more than 10-to-30 minutes to complete, and some are short and simple, such as “where are you based.” Commercial and recreational fishermen, as well as others who are out on the water day after day witnessing changing ocean conditions first-hand, are especially encouraged to provide input. However, anyone who has a stake in this initiative is welcome to fill out the questionnaire on this webpage.

East Coast Fishery Management Organizations Invite Stakeholder Input on Climate Change Scenario Planning

September 14, 2021 — The following was released by the Mid-Atlantic Fishery Management Council:

To help prepare fisheries for an era of climate change, the Mid-Atlantic Fishery Management Council is collaborating with other East Coast fishery management organizations on a climate change scenario planning initiative. Scenario planning is a way of exploring how fishery management may need to evolve over the next few decades in response to climate change. Additional details are available in the introductory brochure.

We are currently in the scoping phase of the initiative. During this phase we are gathering stakeholder input on forces of change that could affect East Coast fisheries in the future. We are inviting all interested stakeholders to complete a questionnaire about the ways you think climate change and other factors will affect fisheries and management in the future. The questionnaire, available at the link below, contains 12 questions and should take 10-30 minutes to complete. This is a great and easy opportunity to become involved and offer your ideas to help guide the issues that we will explore throughout this initiative.

Scenario Planning Scoping Questionnaire

The link will remain open until September 30, 2021, but we encourage you to submit responses as soon as possible. Additional Information about scenario planning can be found at the links below.

Fishery regulators ponder how climate change will affect ocean management 

September 7, 2021 — Fishery regulators up and down the east coast met in a series of remote meetings last week to help them address how fishery management needs to evolve to handle an era of climate change in the coming decades.  

“We’re likely going to have to approach things differently in order to cope with these new and very uncertain conditions ahead,” said Deirdre  Boelke, a fishery analyst with the New England Marine Fisheries Council, at the first meeting, which included participants from several organizations and other members of the fisheries community.  

The “East Coast Climate Change Scenario Planning” series was done to rethink how the fisheries are governed, the different structures of management and how the different regulating bodies on the Atlantic coast would collaborate going forward at a time where species may be moving outside of their traditional range.
