Closed areas can decrease uncertainty in effects of climate change on New England Fisheries

As fishermen around New England will be the first to point out, this summer, much like last year, has been abnormal. The ocean waters were warmer and cod, haddock, and flounders—the mainstay of our fishing industry for centuries—are increasingly elusive. There’s plenty of blame to go around, including decades of mismanagement and overfishing, inexact science and a mismatch in abundance of certain predatory species. Looking beyond these factors, the impact of climate change on fisheries is another factor driving fish abundance that’s worth a hard look.

The level of carbon dioxide in the Earth’s atmosphere has now exceeded 400 parts per million, contributing to rising ocean temperatures. Some of the fastest increases in the last few decades have occurred in the Northwest Atlantic, and 2012 registered the largest annual increase in mean sea surface temperature for the Northwest Atlantic in the last 30 years.  

It is clear that climate change is disrupting New England’s fisheries right now; it is no longer an abstract, future scenario.

In the face of this evidence, fisheries managers need to factor in climate change alongside fishing effort and other elements when determining how to manage and rebuild fish stocks. The impacts of climate change can prevent fisheries management inactions from rebuilding fish populations, and conversely, excess fishing pressure can hinder the ability of a fish population to adapt to changes in climate. As I have written recently, a network of well-designed closed areas represents a promising management strategy to address the effect of climate change on fisheries. Read More »

Earth Day 2013: Awareness, Advocacy and Hope for the World’s Oceans

On this Earth Day, take a moment to appreciate the vastness and intricacies of our world’s oceans. Allow yourself to be mesmerized by the swirling currents continuously circulating the globe. It is amazing that science can meticulously catalog natural systems and present them to those without the ability to see what our Earth looks like from space. What this stunning NASA visualization does not show, are the numerous challenges facing the oceans such as overfishing, ocean acidification, oil spill contamination and plastic waste. While these challenges are largely hidden beneath the waves, increasing awareness, education, scientific research and advocacy have illuminated them. These challenges impact not only the fish and other creatures that live in the ocean, but the billions of people worldwide who depend on clean, healthy oceans for food and eco-tourism.

Fortunately, a growing momentum to save our oceans is emanating from all corners of the world as people see the value and imminent need to preserve marine resources for future generations. The World Bank announced a Global Partnership for Oceans last February 2012, which brings together governments, international organizations, civil society groups and members of the private sector with the common goal of assembling knowledge and financial resources to solve the threats facing ocean health and productivity. This partnership represents a concrete collaboration between global stakeholders to restore the oceans to health, and we are proud to be a part of this effort. Read More »

Fisheries Catch Data: A Tale of Two Approaches

To paraphrase F. Scott Fitzgerald, the test of a first rate intelligence is the ability to entertain two opposed ideas at the same time and still function.

Two views on the importance of catch data for estimating the abundance of fish populations are portrayed as opposing ideas in recent articles, but both of the “antagonists” display first rate intelligence by coming to the same conclusion: catch data send an important signal about the status of a fish population, but other kinds of information must be applied to avoid being confounded by all the other things that affect catch and come to a reasonably accurate estimate of fish abundance.

This argument over methodology may seem arcane, but the stakes are high: estimates of the status of global fisheries based on catch data, which are available for most fisheries, suggest they are in pretty poor shape, because catches have declined sharply in many of them.  But when one looks at stocks that have been assessed by scientists who take into account fishery-independent measures of abundance, the situation looks far less dire, because decreases in catch can result not only from decreased abundance, but also from changes in markets, environmental conditions, regulations, and even in what fish are called – Hilborn and Branch point out that in the 50’s, all sharks were put into only 7 categories, but now there are 36 groups for which catch data are collected, so that reduced catch in some of the earlier categories may merely be the result of re-classification.

‘Fish on Fridays’: Sustainable Fish Choices for Lent

During this season of Lent, millions of people are replacing meat with fish on Fridays.  And as they shop for seafood more frequently, many are also striving to avoid eating fish caught in a manner that further depletes the world’s fish stocks. With 87 percent of the world’s fisheries already fully or overexploited, buying sustainably caught seafood has become increasingly important to consumers.

Today, the best way to ensure you are buying sustainable seafood — and supporting American fishermen and fishing communities — is to buy from a US fishery managed under a system known as a “catch share.” Catch shares reduce overfishing by enforcing annual catch limits and increased monitoring, while granting fishermen a guaranteed share of the catch and greater flexibility in how they run their businesses.

EDF on the Radio: The California Fisheries Fund Helps West Coast Fishermen

CFF Director, Phoebe Higgins with Steve Fitz, a loan recipient

Last week, Phoebe Higgins, Director of our California Fisheries Fund, appeared on the John Young KUIC Hometown Morning show to discuss the productive work the fund is doing to help West Coast fishermen finance their transition to more sustainable fishing practices, improve the profitability of their fishing businesses and provide seafood consumers with the fresh and sustainably caught fish that they love.

Phoebe also discussed with John a new sustainable management program that is helping fishermen on the West Coast grow their fishing operations as well as allowing fish populations to rebound.  The Fund coupled with the Pacific Groundfish catch share program, is helping to maintain and grow California’s highly-valued ocean economy —worth $43 billion and contributing more than 474,000 jobs to the state. Fishermen have more time to fish carefully which improves their safety and dramatically reduces the amount of bycatch and discarded fish. In turn, fishermen are able to bring in higher quality fish to seafood consumers and market their fish at higher prices.

Listen to Phoebe discuss the California Fisheries Fund project and catch share programs on the show and see how one fisherman is benefitting from his loan.

How Behavioral Economics Could Save Both the Fishing Industry and the Oceans

It's frightening enough that 87% of the world's assessed fisheries are fully or over-exploited. But it is even scarier to consider how little we know about the condition of most of the world's fisheries, because four-fifths of them have never been scientifically assessed. A recent study in the journal Science is providing fresh insights into thousands of fisheries where data has not been previously available. These "data poor" fisheries make up 80% of the world's catch — and many are on the brink of collapse.

Despite the dire news, there is a bright spot in the study. The authors conclude that the ocean is nowhere near a lost cause and with the right management tools, the abundance of fish could increase by 56%. In some places, the study says, fisheries yields could more than double.

This isn't just a big deal for the fish. As the authors of the Science study write, "When sustainably managed, marine fisheries provide food and livelihoods for hundreds of millions of people worldwide." So what's the key to seeing such a rebound become reality? An approach to overseeing fisheries known as rights-based management, or catch shares.

Over the past decade, catch shares have taken hold in U.S. waters, ensuring the sustainability of about 65% of the fish landed in the United States. This is the greatest unknown policy success of our time. Don't take my word for it — I work for the Environmental Defense Fund, a policy shop that has long championed the approach. Instead, consider the facts that helped lead the authors of the Science article draw that same optimistic conclusion.

Catch shares are a market-based management tool used in commercial fishing that, coupled with catch limits, have been successful in rebuilding fish populations while improving the efficiency and business of fishing. After decades of failed regulatory regimes, catch shares are working for fish and for fishermen. What's unfolding before our eyes is a global behavioral economics study — one that's delivering major benefits to people around the world.

The Gulf of Mexico red snapper fishery, for example, was on the brink of collapse in the early part of the last decade. Fishermen were limited to 52-day seasons that were getting shorter every year. The shortened seasons, an attempt to counter overfishing, hurt fishermen economically and created unsafe "derbies" that often forced them to race into storms like the boats in The Deadliest Catch.
