Will calamari play an important role in future climate-resilient fisheries?

Besides being the star in calamari appetizers, squid play the crucial roles of both predator and prey in marine ecosystems. Globally, squid can be found in nearly every ocean habitat from seagrass beds, to coral reefs, to the open ocean. Squid fisheries provide livelihoods and high-quality protein to communities, large and small all over the world. And as it turns out, studying squid can teach us valuable lessons about how to build climate-resilient fisheries. A new paper in Fisheries Research will help fishery managers predict where jumbo squid (Dosidicus gigas) populations might migrate under different scenarios of climate change, and help researchers understand why some species are more resilient than others.

While overall squid catches (all species combined) have increased in recent years, it is unclear what the future will hold in the face of climate change and other pressures. Healthy ecosystems depend on resilience from all links of the food chain. This research, which I contributed to along with a number of leading marine research organizations including Shanghai Ocean University, The University of Washington and The University of Maine, suggests that squid may play a more important role in improving climate resilience in the world’s fisheries than previously thought.

China confronts the effects of climate change on fisheries

No nation on Earth is more central to the global seafood system than China. China’s influence on the production, processing, distribution and overall demand for seafood is unparalleled. Indeed, China alone is expected to account for around half of the growth in global seafood consumption over the coming decades.

This growing demand for seafood will require new solutions not only for managing how much fish is caught, but how to adapt as climate change begins to impact China’s ocean ecosystem.  EDF recently convened an international workshop with the China Academy of Fisheries Sciences (CAFS) with the goal of aligning global efforts to identify pressing challenges and solutions to climate change.

As China confronts these impacts, it’s clear that global climate change is a critical stressor that threatens to undermine its hard work on fisheries reforms. China’s government and scientific community recognize this threat, and are beginning to address it. The challenge is not trivial, given that China’s coastline spans 18,000 km, stretching across diverse ecosystems from warm tropical to cool temperate seas.

EDF is working in China not only because of its global importance, but also because we believe the country is in a unique moment for transformative change. China has made ambitious commitments under the 13th Five-Year Plan to improve fisheries management. These include improving the scientific foundation for fisheries management, monitoring fishing activity and catch, enhancing the responsibilities and incentives of fishing fleets and communities and strengthening protection of marine ecosystems.

Five reasons for hope on World Fisheries Day 2018

You may not have it on your calendar – but today is World Fisheries Day – a moment to celebrate the incredible bounty that we receive from the sea. It’s also an opportunity to take stock and reflect on where we’ve been, and where we’re headed. As we look back over the past year, the EDF Oceans team has been struck by how much the global oceans community has accomplished. And we’re increasingly optimistic and energized about the future health and resilience of our oceans. Here are five reasons for hope on World Fisheries Day. Read More »

Science shows that fish are moving, but can fishermen adapt to warming waters?

Europe is already witnessing first-hand shifts in commercially important species such as mackerel, herring and cod. The International Council for the Exploration of the Seas (ICES) recently documented that 16 out of 23 key commercial species in European waters are shifting management areas, with eight of these species moving outside their historic zones.

The North East Atlantic is not immune to the shifts caused by climate change. These waters are home to some of Europe’s most sustainable fisheries as well as complex, highly developed scientific and governance systems. With these complex systems and challenges in mind, the European community is coming together to understand and find effective solutions to the problems being caused by climate change in their fisheries. To spur collaborative action, EDF released a new report outlining tools and approaches to address climate change impacts already being felt in the North East Atlantic region. Read More »

Four lessons from European fisheries to consider in 2018

Almost a year ago, my colleague Erik Lindebo (now walking the corridors of power at the European Commission) wrote this prescient piece on the ‘interesting times’ facing Europe and its fisheries.

This seems like a good moment, as we start the New Year, to reflect on what we’ve learnt during these interesting times, and how those lessons will shape EDF’s work in 2018. Read More »

Examining Climate Change Vulnerabilities of Marine Species in New England

Last week at the Maine Fishermen’s Forum, a session entitled “Questioning our Changing Oceans,” sponsored by The Maine Coast Fishermen’s Association, The Environmental Defense Fund, The Island Institute, and The Nature Conservancy, sought to address some of the major issues related to climate change that the fishing industry has been experiencing. The panel included Jake Kritzer (EDF) as well as local scientists Andy Pershing (GMRI) and Jon Hare (NOAA), along with headliners Capt. Keith Coburn of the hit show ‘Deadliest Catch’, Capt. Buddy Guindon of the new breakout hit ‘Big Fish, Texas,’ and fishermen from as far as Western Australia.

The panel highlighted two NOAA studies recently published in PLOS ONE that highlight the vulnerability of marine fish and invertebrate species such as American lobster and scallops on the U.S. Northeast Shelf to the effects of climate change. Both studies illuminate important trends in species adaptation that will help inform future management decisions in the region. Read More »
