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.

Fishing gear innovations creating great results for fish, fishermen and habitat

Trawl gear modifications produce reductions in bycatch, fuel use and seafloor contact – all with increased catching efficiency.

Over the past couple of years EDF’s Pacific team has been privileged to work with fishermen, scientists, fishing net manufacturers and many others on a three-stage project to demonstrate the feasibility of improved trawl net designs on the West Coast. The video shown here describes the amazing progress we’ve made together and indicates a path-forward for disseminating our results to fishermen everywhere.

Protecting imperiled ocean travelers

Across the globe, populations of many highly migratory species of fish, turtles and marine mammals have hit dangerously low levels. For example, Western Pacific leatherbacks have declined more than 80 percent, and their Eastern Pacific counterparts have declined by more than 97 percent. Many of these species play vital roles in maintaining balanced ocean ecosystems full of diversity and life. As we work to reverse these declines, environmentalists have to ensure that everything we do has the greatest positive impact. This means that we’ll need smart management at home and solutions that protect highly migratory species wherever they roam.

New research suggests that well-intentioned U.S. regulations designed to help species like sharks and sea turtles may actually create a net harm to imperiled sea life.

This unintentional negative dynamic can occur when a country, like the United States, unilaterally adopts a regulation to protect an imperiled species such as sea turtles or sharks caught as bycatch. If the regulation leads to decreased fishing domestically and shifts fishing internationally to countries where bycatch rates are higher, the net result can be a higher number of bycatch deaths for the very species the regulation intended to protect. This phenomenon has been called the “transfer effect.” Read More »
