Five reasons we’re hopeful on World Fisheries Day

The fortunes of people everywhere are inextricably linked to the oceans.  Overfishing remains one of the world’s most pressing environmental challenges, but around the world we are seeing incredible progress toward sustainable fishing.

On World Fisheries Day, we wanted to share fives stories from the past year that inspire us:

Research sheds light on how to better manage small-scale fisheries

Small scale fisheries are critically important for the provision of food security, livelihoods, and economic development for billions of people. Most of these fisheries appear to be under-performing with respect to conservation, food production, revenue, and the quality of the livelihoods they can support.

Many factors related to successful small-scale fisheries management have been articulated in previous research and through practical e xperience, including strong leadership, co-management, secure catch or marine tenure privileges, and scientific assessment of fishery status.   Both the pathways and tools employed in fishery reform vary, but there is a growing consensus that the integration of effective fisheries governance and science-based management is crucial for success.

Together with fishermen and women, community members, managers and scientists we have identified some major lessons that arise from case studies in Belize, Cuba, Mexico and the Philippines. In newly published research, my colleagues and I evaluate the stories, challenges and lessons learned from these fisheries, where these groups are developing science-based solutions for sustainable fishing. We found that successful science-based management includes fisher participation and empowerment, partnership across sectors and community buy-in, and sound scientific analysis. Read More »

New online training will enable better fisheries management

What if anyone in the world could access expert help and advice on fisheries management with just the click of button?

Overfishing is a global problem that can only be overcome by a global effort to address it. But there is no one-size-sits-all approach. Fisheries managers need access to tools and methods that can be effective on a local scale.

Our Virtual Fisheries Academy is a new resource for fisheries management professionals all over the world. Getting strong fisheries management in place around the world relies on an empowered network of fishery managers, fishermen, scientists and other practitioners who have the knowledge and skills to develop fishery management solutions that work for their fisheries.

How important is the role of science in managing U.S. fisheries?

Environmental Defense Fund (EDF) is proud to sponsor a panel this week at the annual meeting of the American Fisheries Society (AFS) – the nation’s preeminent organization advancing fisheries science – that examines the role of science in federal fisheries management. Ten years ago, Congress gave science a stronger role in fisheries management. Today, overfishing has dropped significantly in U.S. waters and we have seen a number of fish stocks successfully rebuilt. Coincidence? Unlikely.

This week’s panel will examine what part the strong scientific provisions of the law have played in rebuilding fisheries, new scientific innovations needed to address remaining challenges, and whether any additional changes to the law could further strengthen management success. Read More »

How science and technology can help save sharks

Every year, Shark Week gives us a peek into the world of shark research and the amazing science and technology developing to study these captivating animals. This year, we were amazed by ultrasounds for pregnant hammerhead sharks and measuring a goblin shark’s bite.  The latest science and technology can also help fishermen seeking other species to avoid sharks, protecting them from a significant source of injury and death while saving fishermen money.

Globally, shark bycatch represents one of the greatest threats – maybe the greatest threat, — to shark populations. Worldwide, sharks caught as bycatch can make up nearly half of the total reported catch, and that’s not counting the large amount of catch that goes unreported. Often, fishermen want to catch more valuable species like swordfish and tuna using pelagic longlines, one of the most prevalent fishing gears on the high seas, and hate accidentally catching sharks instead. So how can science and technology help solve this problem? Read More »

Science, warnings and the plight of coral reefs

A tragedy is unfolding on the Great Barrier Reef, the largest living organism on the planet.  The non-Hollywood ending is a surprise to many, but it was clearly foreshadowed decades ago by a small group of scientists who were criticized as false prophets of doom and dismissed.

Large sections of the reef are dead.  The reef has been remarkably resilient over the last 8000 years, weathering devastating outbreaks of voracious crown-of-thorns starfish, pollution, fishing and coral bleaching.  The establishment of the Great Barrier Reef Marine Park Authority no doubt contributed to that resilience, reducing impacts from some of these threats, especially land-based pollution and fishing pressure.  Recent research by EDF and others shows that managing fisheries is crucial for maintaining healthy coral reefs.
