Joint U.S.-Cuba-Mexico shark catch share gaining media interest

This weekend Reuters wrote a story about two EDF staff members’ recent trip to Cuba. Last week Dan Whittle, Pamela Baker and U.S. scientists visited with Cuban officials to discuss collaboration between the U.S., Cuba and Mexico to better protect the Gulf of Mexico’s struggling shark population. EDF and Mote Marine Laboratory are promoting improved management for sharks, including exploration of catch share management systems increasingly used to meet the conservation and economic objectives in diverse parts of the world.

Shark populations have been troubled for years, primarily due to overfishing, in part resulting from China’s high demand for shark fin soup. Sharks are “highly migratory,” meaning they travel throughout the Gulf and beyond, not just in U.S. waters.

For Gulf sharks — and the benefits they provide to local communities — to be sustained over the long-term, a cooperative effort between the three countries that fish in Gulf waters is key. Catch shares can offer advantages over conventional regulations by creating incentives for fishermen to focus on a steady and high quality catch over higher volume, often lower quality harvests. Important political and other challenges exist, but the potential benefits of cooperation make the effort worthwhile.  Management programs should be designed to achieve the conservation, economic and social objectives of the three countries.

Read the full story.

At the end of September, EDF will be participating in a tri-national workshop with U.S., Cuban and Mexican scientists to finalize a long-term marine research and conservation plan for the Gulf of Mexico at Mote Marine Laboratory in Sarasota, Florida. Sharks will be discussed as one of six working groups focused on priority resources in the Gulf of Mexico. More information will be posted on EDFish as the event approaches.

“Red Herrings” in the Gulf of Mexico – Part 2: Key Ocean Ecosystems at Risk

This is the second post in a four part series discussing the ongoing – and “cascading” – effects in the Gulf, not from “oil,” but rather its toxic components and their impacts on sensitive ecosystems. Read the rest of the series.

I remain extremely concerned about what has happened to the out-of-sight, underwater ecosystems of the Gulf of Mexico, especially at middle depths and on the bottom. These little known but ecologically vital elements of the ocean have been heavily exposed to oil-based pollution, both rising from the bottom and sinking back down from the surface, and – at least in some places – bathed in persistent underwater toxic plumes.

Marine life in the mid-waters is so rich and profuse in places that sonar waves bounce back as a “deep scattering layer” and provides key food for many familiar, surface-diving animals, including whales, dolphins, billfishes and giant tunas. Deepwater coral reefs and other bottom dwellers have been at great risk all along, and not even the initial explorations have yet been done to assess the impacts of reefs less than twenty miles from the broken well bathing in oil-based pollution.

The oil and oil-derived pollution that made it to the surface followed – and is following – one set of pathways through the Gulf ecosystem, exposing and injuring not just sea turtles and sea birds, but also near-surface marine animals and plants, large and small, and entering foodwebs through a complicated series of entry points, which we don’t yet fully understand.

Fine droplets of dispersed pollution are more likely to be adsorbed onto particulates, sinking back through the midwaters and into the abyss. The moreresistent elements, like tar balls, either float away or sink back into the abyss, and follow a different set of pathways.

The total “dump” of highly toxic oil components, including low-molecular weight aromatic hydrocarbons (known familiarly as “BTEX” – benzene, toluene, ethyl benzene and various xylenes), could have been up to 50,000,000 gallons. These are heavy-duty pollutants in their own right, including known carcinogens and reproductive toxicants, with a fair solubility in sea water. In a surface spill, pollution mostly evaporates, and the only real concern relates to emergency response workers that are exposed while on duty. In this underwater case, scientists simply do not know – yet – exactly how the massive load of pollution is being processed in the Gulf.

“Red Herrings” in the Gulf of Mexico – Part 1: It Ain’t the Oil

This is the first post in a four part series discussing the ongoing – and “cascading” – effects in the Gulf, not from oil, but rather its toxic components and their impacts on sensitive ecosystems. Read the rest of the series.

In recent weeks, nearly every discussion about the BP Oil Disaster in the Gulf of Mexico has focused on the question: “how much of the oil from the broken well is left in the Gulf?” 

The answer is simple:  “None – it ain’t the oil, stupid!”    

For some time now,  the problem hasn’t been the oil in the Gulf,  it’s the complicated series of impacts caused by the diverse substances that made up the oil as they are degraded in stages, both biologically and chemically. Each step along the way – and even the final breakdown products – poses important threats to a different suite of living things.  The total damage done by this complex array of shifting impacts on the sensitive ecosystems  and the people of the Gulf remains largely unknown.


Sure, some elements of the complex ecology of the Gulf of Mexico may get off scot-free from the disaster.  But many others have been or will be heavily impaired, at least for some time.  Taken together, there will be a significant total effect on the ecological systems of the Gulf, including the productivity and safety  of seafood, and significant  bottom-line impacts will be felt  on human health and social and economic well-being. 

Oil or Not Oil?

From the beginning of the disaster back in April, as “Gulf Light Sweet Crude” oil spewed  into the depths of the Gulf, the components of that oil – a “toxic soup” of hundreds of different chemicals – have been subjected to intense physical, chemical and biological sorting and processing, and to transportation by currents both towards and away from shore. 

This is an underwater look at one of the oil plumes in the Gulf of Mexico in late May. Click to watch the video.

By the time the well was capped in mid-July, a significant amount  of the approximately 200,000,000 gallons of liquid flowing from the broken well made it to the surface as recognizable oil.  But from the very beginning, the various “toxic soup” ingredients have followed radically different pathways through the complex oceanographic and living systems of the Gulf, spreading and being processed in different directions at different depths, and at different rates.

It is clear that all layers of the sea in a large zone around the well have been exposed, from bottom to top, as the spreading and rising cone (or “plume”) of oil-based materials spewed from the well. In contrast to a more typical oil spill on the water’s surface, where the transport and ecological fate of oil components are well-known, there are still many unknowns related to how the various chemicals have moved and are breaking down underwater, including the biochemical pathways and timetables.  Intense scientific investigation and complicated modeling are necessary before these complex relationships can be understood fully.

The addition of dispersants, both at the bottom and the top of the water column, has further altered the chemicals’ pathways through the ecosystem,  likely lessening some kinds of impacts and exacerbating others.It may well turn out that chemicals derived from oil spread over a much larger area because of the addition of dispersants, both at the bottom and the top.  The final accounting of the ecological and human winners and losers has yet to be made.

At the end of the day, the complex set of effects on the living systems of the Gulf from the oil and its chemical components will be understood, more or less.  The impacts on the human populations will be estimated, if not fully understood.  It is grossly premature to declare victory, though, until we understand the ways in which the basic fabric of the ecosystems of the Gulf has been altered, and what might be required to restore its weave.

A Lifeline for Gulf Fishermen: Catch Shares Cushion Blow for Commercial Snapper Fleet in Wake of BP Oil Disaster

At the time of the BP oil disaster, the once-failing Gulf commercial red snapper fishery was beginning to rebound, in large part due to a catch shares program called individual fishing quotas introduced in 2007.  Before catch shares, fishermen competed against each other in a dangerous race-to-fish before the short seasons ended. Now, fishermen are assigned a percentage of an annual sustainable catch and have a year round season. Individuals decide when to fish their secure amount, and can trade their allotments with other boats, providing incentives and accountability to save fish and the marine environment.

The system works for fishermen and fish. Before, regulations forced fishermen to throw out millions of fish, wasted and dying. Fish were caught during short seasons and were sold in the market all at once, pushing down quality and fishermen’s earnings. Now, far fewer fish are wasted, fishing costs are dramatically lower, and fishing trips are timed when seafood demand is high.  In short, opportunities for a healthy Gulf and fishing industry are possible again.

While all Gulf fishing businesses have been harmed, catch shares have cushioned the blow for fishermen during the BP oil disaster in the following ways, as non-catch share fishermen – like red snapper charter fishermen – are stuck dealing with another huge blow to their industry.

  • Tangible assets to make loss recovery claims: Catch shares have a transparent market price, which may help fishermen calculate defensible claims for the loss of value of their business and assets from the oil disaster. In contrast, fishermen under old rules may find it difficult to prove the expected value of this year’s and future catches. This case is likely the first in which disaster claims can be based on catch shares.
  • Ability to trade fish now to make ends meet: Catch share fishermen in areas closed by the spill can trade their shares to others in the open Gulf waters, giving them the means to survive in the short term. In contrast, fishermen under old rules are stuck at the docks with nothing to trade.
  • Security to wait and fish later in the year: Catch share fishermen have a year round seasons and secure amount of fish, allowing them to save their fish for later in the year. For those under old rules, like charter fishermen, important fishing seasons are often concentrated during summer months, so fishermen that have been closed in by oil from Louisiana to Alabama have missed out on fishing for some prized fish and substantial fishing income.  (Regulators may re-open some fisheries to alleviate hardship caused by the oil disaster.)

Overall, catch shares help make fishermen more resilient to man- made disasters like the BP oil disaster and natural disasters like hurricanes.

Now more than ever, we need to improve fishery resiliency, reduce waste and make every fish count — for the environment and for fishermen. Catch shares are the best way to make this happen.

Solutions That Work for the Environment and Economy are More Important Than Ever

We recently released a new video highlighting the results of our Gulf of Mexico Longline Gear Conversion Program, in which we helped nearly 50 boats convert to more environmentally friendly fishing gear in West Florida.

We launched the Longline Gear Conversion Program last year in response to regulations that shut down longline fishing, after the government found that the gear was “interacting” with too many sea turtles. The ban on this widely-used type of gear was devastating for many communities in West Florida.

Environmental Defense Fund believed there was a better way to keep fishermen on the water and sea turtles safe. Our program paid up to 50% of the costs for fishermen to covert to gear that was better for sea turtles and kept fishermen on the water. Many fishermen told us they wouldn’t have been able to make the gear change without our help.

This type of win-win solution is what EDF does best.

The 2010 BP oil disaster demonstrates that initiatives like this one, which help fishing communities and the environment, are more important than ever.

3 Months In: New Bedford Standard Times Provides Insight into the Progress of Catch Shares in New England

Julie Wormser, NE Regional Director for EDF Oceans program.

Julie Wormser, NE Regional Director for EDF Oceans program.

This past Sunday, the New Bedford Standard Times published a set of three articles that gave insight into the progress of sectors (group catch shares) in Massachusetts. 

There is good news in the articles:

  • The fishermen who are fishing are seeing higher revenues, while others are waiting for prices to increase, a strategy they are free to employ under this system.
  • Sectors such as the one in New Bedford, managed by David deOliveira, are working together to manage their allocations of scarce stocks to “keep everyone fishing.”
  • Leasing allocations is of real value financially to fishermen considering retirement.

The articles also highlight improvements to the sector system that can and should be made as well as the challenges associated with low catch limits, which is entirely unrelated to catch shares. Many of these issues are currently being discussed by the industry, the New England Fisheries Management Council, and conservation groups. 

Many opportunities identified in the articles are a function of how the catch share was designed.  Catch shares can be designed to accommodate the communities that depend on fisheries. 

Catch limits

As Don Cuddy’s article points out, “Many fishermen believe their economic woes are not a result of sectors or any particular management system but from catch limits that they believe are set artificially low.”

The 2010 catch limits were developed based on NOAA’s best available science. But carefully targeted investments in science and scientific processes – including those outlined by Senators Kerry and Snowe in their recent appropriations request — can provide relatively quick improvement in assessments of key stocks, and may well increase allocation of certain stocks.

There are several design elements that can help the fleet through times of low catch limits.  For example, the Pacific groundfish fishery held back ten percent of the quota for “adaptive management” and has already dipped into that quota to provide additional allocations of a particularly weak stock—canary rockfish—for fishermen who lacked enough to legally fish for other species. 

Consolidation

In Steve Urbon’s NBST piece, he discusses the “consolidation of the industry.”  While that is a concern, it has to be weighed against the consolidation of the fleet that was occurring under the previous Days-At-Sea (DAS) management system.

In the New England groundfish fishery, in 2001, 1,100 active boats used 65,347 groundfish DAS for an average of 60 DAS per active vessel.  In 2007, 574 active boats used 32,804 DAS for an average of 57 DAS per active vessel.   As the number of days fishermen were allowed out on the water dropped dramatically, so too, did the number of boats fishing.

There are design elements in catch share systems around the world that can alleviate some of the consolidation concerns while supporting fleet diversity, smaller ports, and small-scale fishermen with less access to capital. 

For example, quota accumulation caps could be used to limit the amount of fish that any one participant has access to.  The Interspecies Committee of the New England Fishery Management Council voted unanimously at its April 2010 meeting to recommend to the full Council that accumulation caps be developed and implemented for the 20 groundfish stocks managed under sectors.  This action can help protect the smaller boats by preventing the fleet from being dominated by a few big players.

Limiting permit transferability, ownership and use is also used to achieve specific objectives.  For example, some catch share systems require a certain percentage of the harvest to be landed in specific ports to protect the shoreside infrastructure.  Other fisheries require quota owners to be on board in order to catch their share in order to discourage corporations from acquiring large amounts of quota.   

Moving forward

Much of New England’s fishing community has struggled over the past several decades.  Regulations meant to bring back once-abundant cod, flounders and other groundfish have instead squeezed the fleet’s profitability.

Sectors can help the New England groundfishery move towards an increase in fish populations; an increase in per-boat revenues; a dramatic reduction in bycatch and an increase in the use of sustainable fishing practices.

The New Bedford Standard Times has raised important questions and opportunities for improvement in the groundfish fishery.  Now is the time to make refinements to New England’s groundfish sectors.  There are many options and the best outcomes will likely occur when all stakeholders – fishermen, shoreside businesses, conservation groups, legislators, and Council members — participate in the process with the shared goal of creating a fishery with healthy fish stocks and thriving fishing communities.
