Catch Shares: Harvesting Sustainable Catches
Written by Steven Katona, Managing Director, Ocean Health Index
Maximizing sustainable food production from the ocean by harvest of wild fish stocks and production of farmed species by mariculture is one of the 10 goals evaluated by the Ocean Health Index, and it is especially closely watched because it is so critical for the future.
Three billion people out of today’s world population of 7.1 billion people depend on seafood for their daily protein and fish contribute a greater proportion of protein to the average diet than poultry. A single serving of fish or shellfish (150 g) provides 60% of a person’s daily protein requirement, but the ocean’s continued ability to meet that need is in doubt. Our population is rising steadily and will reach about 8 billion by 2024 and 9 billion by 2040, but the annual catch from wild ocean fisheries has stayed at about 80 million metric tons since about 1990 despite increased effort. The reason is that too many stocks are overfished and too much productivity is sacrificed as bycatch, illegal and unregulated catch and as a result of habitat loss caused by destructive fishing practices.
Yet without increased wild harvest and augmented mariculture production, the risk of malnutrition will increase for hundreds of millions of people, because the catch will have to be shared by so many more mouths.
Why would we expect fish landings to increase in the future if they haven’t done so since 1990? Clearly with business as usual, they won’t, but a number of new strategies and tools offer hope. Catch shares is one of them. We’re pleased to welcome Kate Bonzon, Director of Environmental Defenses Fund’s Catch Share Design Center, to explain how catch shares are working worldwide and highlight some of their benefits.
Even though catch shares have been used in a diversity of fisheries around the world, the idea of catch shares is new in many places, and it has occasioned some misunderstanding and subsequent debate around the best way to manage fisheries. However, catch shares give a powerful incentive and opportunity for fishers to care for their fish stocks, thereby improving the consistency, sustainability and possibly magnitude of their catches, while also improving their livelihoods.
More sustainable fishing will not only help fishers and fish stocks, but it will also improve scores on many of the other goals evaluated by the Ocean Health Index. Of course there are trade-offs between the goals, but meeting the goals for sustainability embodied within each goal will improve the ocean’s ability to sustainably deliver a range of benefits to people now and in the future. What’s more, the ocean’s animals, plants and habitats will benefit too.
Catch Shares: Harvesting Sustainable Catches
Fish were once thought to be so abundant that we could take our fill and never deplete them; that wild fisheries were inexhaustible and would always be plentiful. But over the past few decades, there is growing recognition that most of the world's wild fisheries are in trouble and fishing has had a tremendous impact. Globally, nearly two-thirds of wild fisheries are overfished, leaving depleted fish stocks and low yields. New evidence on fisheries with little data, which account for 80% of the global catch, is especially concerning. Once thought to be relatively stable, many of these fisheries are, in fact, overfished and facing collapse. Depletion of this resource threatens not only ocean health but the billions of people who depend on fish for food and jobs.
The good news is fisheries are a renewable resource. And the key to sustainably managing them is ensuring there are enough fish left in the ocean to produce future generations. Future fish generations will keep fresh and sustainable seafood on the plates of the billions of people around the world who rely on them for protein, and wages in the pockets of millions of fishing industry workers who depend on them to support their livelihoods.
And there is more good news. There are effective fishery management programs-called catch shares-that are doing all of the above. As of 2013, about 200 catch shares programs are managing more than 500 different species in 40 countries. Very much like dividing a pizza or pie, catch shares give a secure fishing area or privilege to catch a share of a fishery’s total allowable catch to an individual or group. And with this privilege, fishing participants are expected to fish within their allotted amount.
of catch shares lies in the ability to give fishermen a long-term stake in the
fishery and tie their current behavior to future environmental outcomes.
Specifically, catch shares align fishermen’s incentives through a system of
rights, responsibilities and rewards. By giving fishermen the privilege or right to a secure area or share of the
catch, fishermen also retain the responsibility
to conserve fish stocks and marine ecosystems and are subsequently rewarded by stable and healthy fish
populations. Importantly, catch shares
are flexible and can be custom designed to meet the different characteristics
and goals of diverse fisheries. Some
catch share programs have allocated shares to groups—often called Cooperative
catch shares—and others have allocated shares to individuals—often called
Individual Fishing Quotas (IFQs) or Individual Transferable Quotas (ITQs). Area-based catch shares, often called
Territorial Use Rights for Fishing, or TURFs, allocate secure, exclusive areas
to fishermen. And within these differing types of catch shares are a multitude
of design features that have, and can, be used to meet different goals. Around
the world, from small artisanal fisheries to large commercial fishing
operations, well-designed catch share programs are increasing compliance with
catch limits, reducing the amount of bycatch and discarded fish, increasing
revenues and reducing fishing expenses, proving that good yields can indeed
happen sustainably. A 2011 study of 345 fish stocks around the world found that
those managed with catch shares had significantly lower cases of
overexploitation when compared to conventional management practices. And
another study found that the implementation of these systems “halts, and even
reverses—widespread fishery collapse.” This positive trend is largely driven by
catch shares ability to encourage compliance with mortality controls.
Numerous studies on these fisheries have reported a dramatic drop in bycatch and discarded fish including a National Oceanic and Atmospheric Administration (NOAA) report which found that catch share fishermen in the Gulf of Mexico reduced red snapper discards by 50% in 2010, just three years after a catch share program was implemented. And in some fisheries like the Alaskan pollock fishery, fishermen create voluntary no-take zones to avoid bycatch of at-risk species while targeting specific species. In the Alaska halibut fishery after just one year of catch share implementation, there was an 80% drop in ghost fishing (when lost or abandoned gear continues to kill fish).
Many of these fisheries
used catch shares to meet their own specific goals, such as economic
self-sufficiency. In Samoa, the culture and livelihood of many native
communities relies on the practice of fishing. In fact, in the Safata District
of Samoa, a settlement of nine villages on the remote southern coast of Upolu, the
community is highly dependent on fisheries as a source of food and income. Approximately
88% of households engage in fishing activities and the community derives about
77% of its entire food source from adjacent lagoons and reefs.
For centuries, village chiefs successfully managed coastal fishing areas through secure and exclusive tenure over defined fishing areas in a practice known as “matai.” After colonization took place in the 1800s, these chiefs and their native communities lost ownership of their seas. In the mid-1980s, the island’s inshore fisheries were at risk due to overexploitation of stocks and destructive fishing practices.
The Samoan government worked with the native fishing communities to help them develop village-based management programs. The Safata District was able to develop a district-wide TURF in 2000, which created bylaws to manage community members’ fishing efforts and limited outsiders’ access to their fishing area. And this has all proved to be fruitful. After development and implementation of the TURF, food fish and other important species have increased in abundance and the district is now known as one of the largest and most successful community-managed areas in Samoa. The community’s catch share, Samoan Safata District Customary User Rights Program, has resulted in strong community support, high compliance with regulations and the community’s members are reporting increased catches despite spending less time fishing.
In Japan, fishing Cooperatives coordinate within and across TURFs to improve fishery sustainability and promote economic efficiency. Since the early 1700s, local Japanese fishermen formed to protect their nearshore marine resources. However in the 1930s, when coastal fishing boats became motorized, fishing pressure increased and become more difficult to regulate. Overfishing and conflicts among fishermen began to occur, primarily between coastal fishermen and industrial trawlers. The Japanese government addressed this by formalizing the rights and co-management responsibilities of local cooperatives as part of the Fishery Law of 1949. Almost 65 years later, the Japanese Common Fishing Rights System has enhanced coastal fishery management. Fishermen work together within their Cooperative to effectively manage their share of the resource and they work across Cooperatives to ensure good management of resources that straddle multiple communities. The program established a system of nested governance that provides fishermen with a voice in the management process. And importantly, the program allows Cooperatives to ensure compliance with catch limits that support the health and sustainability of their fisheries.
just two success stories of many instances where catch shares are helping to
achieve the food provision goals of fisheries. And at Environmental Defense
Fund (EDF) we are working to ensure that fisheries stakeholders have access to
the knowledge and tools needed to implement sustainable fishery management
programs that allow them to achieve all of their goals, whether they are environmental,
social or economic.
We recently released a comprehensive toolkit for designing and implementing such systems. The toolkit provides fishermen and fishery managers with many low-cost and highly replicable solutions to management issues, including a guide on science-based management of data-limited fisheries. It expands upon our original Catch Share Design Manual released in 2010 and includes feedback and guidance from more than 80 global experts.
The toolkit can be found at fisherytoolkit.edf.org, and consists of:
updated Catch Share Design Manual that guides fishermen and
fishery managers through a step-by-step process to design catch shares
