Destructive Trawling and the Myth of “Farming the Sea”

In the wake of significant but highly warranted cuts to catch limits for cod, the New England Fishery Management Council spent the last day of their most recent meeting in January discussing the development of a suite of habitat protection measures known as the Omnibus Habitat Amendment. Despite the obvious need for new habitat protections to help restore Atlantic cod populations, the Council had already taken action to potentially open over 5000 square miles of previously protected areas to destructive bottom trawling. By doing so, the Council has continued to demonstrate a lack of regard for the immeasurable documented benefits of habitat protection to the health and productivity of our fisheries.

Even more concerning were the misperceptions of the effects of bottom trawling on display at the January meeting—even by members of the Council itself. Laura Ramsden, a relatively new member of the Council and an owner of the Boston-based seafood distributor Foley Fish Company, suggested that the scientists tasked with evaluating habitat protection priorities might be missing the benefits of bottom trawling. She asked the members of the Closed Area Technical Team: “As you’re evaluating the different areas, are you also taking a look at potential damage of closing them in terms of invasive species and the potential risk of not ‘tilling the soil’, if you will?”

The inexplicable myth that bottom trawling might “farm the seabed” is all too common, but it has no foundation in scientific reality. There are few serious studies that suggest that trawling may increase any kind of food production, and they are very limited in scope. A single study suggests that plaice in the North Sea may benefit from the reduced competition and increased production of some invertebrate species on which they prey. But the trawling is very limited—1 or 2 trawl passes a year—and the study does not examine the effects on other species of tearing apart complex bottom structures, removing higher trophic level predators, and reducing natural competition and biodiversityA second, empirical study found that higher levels of trawling reduced productivity of even small invertebrates and that variability in productivity was far more closely linked to climate change than bottom trawling.

There is similarly scant scientific evidence for Ms. Ramsden’s assertion that trawling has any beneficial role in limiting the spread of invasive species. On the contrary, multiple studies suggest that human disturbance makes habitat more vulnerable to the spread of invasive species.

Meanwhile, the scientific consensus on the destruction caused by bottom trawling is nearly unanimous. It’s hardly surprising that dragging massive trawls along the seafloor destroys habitat—scallop dredges can weigh up to a metric ton (2205 lbs), and furrows up to 20 centimeters (8 inches) deep are common in trawled areas. A recent study in European waters even showed bottom trawling was changing the bathymetry of the seaflooron a massive scale.

Numerous scientific studies have shown that trawling  lowers overall productivity and can completely change the composition of local fish populations. Trawling tears apart biological structures like kelp forests and sponges and flattens out the seafloor structures that protect juvenile fish, leading to increased predation and reduced recruitment. It reduces biodiversity and species richness, which have been repeatedly shown to build resilience to invasive species. And areas with complex bottom structure, like the rocky ridges and horse mussel beds of current protected area Cashes Ledge, are the most vulnerable. In some areas trawling can stir up so much sediment—which then settles to smother eggs, larvae and other ocean creatures—that it leaves a trailing plume visible from outer space.

Protecting valuable habitat areas from trawling provides more spawning adults and juvenile fish, harbors older females with higher rates of reproductive success, and protects complex habitat like kelp forests. The current protected areas have proven themselves beneficial to struggling fish populations—they have helped scallop populations recover, and some species, like haddock, are larger and more abundant inside these closed areas. Fishermen target the edge of the protected areas because they know that more and larger fish can be found there.

Opening protected areas to bottom trawling threatens to instantaneously reverse these benefits. The best scientific evidence is that bottom trawling does not “till the soil”, but that opening protected areas will destroy vital habitat and keep cod populations from recovering. NOAA and the Council should heed the scientific record and make the right decision—to keep bottom trawling out of the groundfish closed areas.

For Valentine’s Day, a Special Love Note from the Sea

Feb 14, 2013 by  | Bio |  Leave a Comment

Flowers, a heart-shaped box of chocolates, a warm and tender love song, and a glittery card with completely over-the-top sugary sentiment…these are the tokens of affection we most recognize on Valentine’s Day. If you’re one of the lucky ones, that special someone will deliver a heartfelt token that makes your day even more meaningful.

It could be surprising to many people that in our complex and amazing world of ocean animals there are several creatures known for displaying the type of deep affection and commitment of which only romance novelists can dream. Tropical angelfish and at least one type of Australian seahorse are not strangers to life-long love beneath the waves. (And, by the way, is there any name more apropos to a day celebrating intimacy and devotion than that of the deep-sea sponge known as “Venus’s flower basket?”) There is even a small unglamorous freshwater fish known as the convict cichlid which pairs off into a crevasse made into a home to raise their children.

Without a doubt, our own Atlantic Wolffish exhibits the special bond of love suitable for Cupid’s attention. Male and female pairs (who reportedly mate for 3 to 6 hours at a time and practice internal fertilization, a rarity in fish) seek out their own special love nest under a craggy rock, or maybe down along the hull of a sunken wreck, just big enough to guard the egg mass laid by the female. The male wolffish, exhibiting no scientifically observed “commitment issues,” stands guard at his cave haven ensuring the protection of the growing larvae and juvenile offspring. The male is so devoted that he stops eating for as long as he is on guard, sometimes as long as four months. Not only is the wolffish pair committed to each other, they are highly loyal to their habitat.

Without a place to call their own, the wolffish love story could have an unhappy ending. With wolffish numbers having declined drastically in the last three decades, the connection between wolffish and their undisturbed habitat is even more important. Wolffish are still caught as bycatch in trawls and, possibly even more damaging to their long-term survival, their rocky habitat gets swept away by trawls and nesting areas can be buried in the sediment stirred up by trawling gear. Recreational anglers often catch wolffish, but it’s proven that the wolffish can be safely returned to the sea with the proper “catch and release” practice. (Wolffish do not have a swim bladder that “blows up” on the surface.) For both recreational and commercial fishermen in federal and state waters in New England it is illegal to possess or land Atlantic wolffish. If enforced properly, this can be a great step forward for wolffish conservation.

Now, it may be said that the Atlantic wolffish has a face that only its mother could truly love. But isn’t that the mystery of love itself – finding one’s counterpoint in the ocean of uncertainty can be anything but predictable.

Waves of Change: Who’s in Charge Here?

Jan 11, 2013 by  | Bio |  Leave a Comment

Rules work better when we all understand them, but what happens when the rules overlap or conflict with one another? And, who is in charge of implementing all these rules anyhow? When it comes to the rules of the road we all learn the same common rules during the drivers’ education course. But, what happens when it comes to the rules which manage and protect our ocean and coasts?

Ocean and coastal resources are currently managed by more than 20 federal agencies and administered through a web of more than 140 different and often conflicting laws and regulations. We use our coasts and ocean for so many things – fishing, boating, swimming, tourism, shipping, renewable energy – and there are no easy guidelines about who is in charge at any given moment, in any given spot.

Fortunately, we are on our way to making this puzzle of governance a bit easier to solve.

The National Ocean Policy directs federal agencies to coordinate management activities, implement a science-based system of decision making, support safe and sustainable access and ocean uses, respect cultural practices and maritime heritage, and increase scientific understanding of ocean, coastal and Great Lakes ecosystems.

Improving the way in which federal and state agencies work with each other and the public is a distinct goal of the National Ocean Policy. To do this, the NOP presents a set of nine priority objectives for policies and management actions and establishes a new National Ocean Council (NOC), which will be responsible for developing strategic action plans for these priority objectives and leading coordination and collaboration between federal agencies.

A well coordinated group of agencies can better serve the people they are supposed to serve, create the jobs and economic benefits we all need, help us enjoy and safeguard our waters, beaches, and wildlife for our families and our future.

There’s No Place Like Home for the Holidays

Will you help keep this Atlantic wolffish home for the holidays?

For the holidays you can’t beat home sweet home. “Home” means something different for each wildlife species in their ocean habitat of the Gulf of Maine. For example, animals like the Atlantic wolffish  tend to live in rocky areas where they can hide out, guard their eggs and ambush prey. Wolffish depend on this particular type of habitat to live, and other species are just as dependent on other types of habitat. Places such as Cashes LedgeJeffreys Ledge and Stellwagen Bank National Marine Sanctuary provide rich habitat for highly depleted cod and haddock, sea turtles and four species of whales.

Most of these three areas in the Gulf of Maine currently benefit from fishing regulations which prohibit harmful bottom trawling, but these protections are temporary. With groundfish populations at their lowest recorded levels, some members of the trawling industry are pushing for regulations to increase trawling in the few protected habitat areas in the Gulf of Maine. After being declared a “fishery disaster,” changes in regulations to allow bottom trawling in Cashes Ledge, Jeffreys Ledge and the only protected portion of Stellwagen Bank National Marine Sanctuary seems counterintuitive to ever devising a long-term strategy that could help restore groundfish populations in the Gulf of Maine. At a time of the lowest recorded groundfish populations in history, how does it make sense to increase bottom trawling in the best, remaining habitat areas?

This week the New England Fishery Management Council (NEFMC) could make some decisions that decide the fate of important habitat areas in the Gulf of Maine. On Thursday, Dec. 20th, the NEFMC meets to consider fishing catch limits and proposals to allow trawling in currently protected habitat areas. The NEFMC is an important advisory body to the National Marine Fisheries Service, but it is really NMFS who is legally responsible for providing sustainable management of this public resource and it’s NMFS who has the responsibility to adequately protect ocean wildlife habitat. If there is a time to take action to help put this fishery on a path to eventual recovery, it is now.

Other New England fishermen, both commercial and recreational, understand the value of protected habitat and how healthy habitat benefits their own interests. In fact, the recreational fishing advisory panel of NEFMC voted in October to retain all current protections for habitat areas. Recreational fishermen and charter captains from Maine to Rhode Island well know that the cod their clients catch in the Gulf of Maine spawn from areas where large bottom trawlers are not allowed. In the words of one recreational fishing captain, “I’m not an advocate of opening any of the closed areas and dead set against the opening of the WGOM (Western Gulf of Maine) area. You’re destroying the livelihood of the recreational boats and you’re allowing the big boats to compete with the little boats.”

NOAA needs to hear this message loud and clear. Send a message to NOAA to urge the responsible protection of Cashes Ledge and other important habitat areas in the Gulf of Maine. Because, no matter where you celebrate your holidays, healthy ocean habitat is a gift that benefits us all.

Healthy Habitat Helps Create Healthy Fisheries

Dec 14, 2012 by  | Bio |  Leave a Comment

One of the fundamental concepts of marine ecology and modern fisheries management is that fish and other ocean wildlife need various types of habitat to feed, grow, and reproduce. Healthy ocean habitat is crucial to the well-being of ocean ecosystems and also provides spawning grounds for commercially important groundfish. New England’s ocean waters are home to several special places that deserve permanent protection.

Cashes Ledge, an underwater mountain range 80 miles off the coast of Maine, supports the largest and deepest kelp forest off the Northeastern United States and is home to an enormous diversity of ocean wildlife – from whales, Atlantic wolffish, and blue sharks, to fields of anemones and sponges. This kelp forest provides an important source of food and habitat for a vast array of ocean wildlife. Other places such as Jeffreys Ledge and Stellwagen Bank National Marine Sanctuary provide rich habitat for highly depleted cod and haddock, sea turtles, and four species of whales.

Most of these three areas in the Gulf of Maine currently benefit from fishing regulations which prohibit harmful bottom trawling, but these protections are temporary. Some of the largest commercial fishing trawlers in the region are pushing for changes in regulations to allow bottom trawling in Cashes Ledge, Jeffreys Ledge and the only protected portion of Stellwagen Bank National Marine Sanctuary.

After the last cod crisis in the 1990s the New England Fishery Management Council (NEFMC), after a court decree spurred by a CLF legal action, designated Cashes Ledge and an area known as the “Western Gulf of Maine” which holds Jeffreys Ledge and 22% of Stellwagen Bank National Marine Sanctuary, as “mortality closures.” The action restricted destructive trawling, but it allowed a wide array of other commercial fishing gear such as bottom gillnets, purse seines, hook and line and more the questionable practice of “mid-water trawls,” which despite their name, often catch groundfish. Recreational fishing and charter boats were not restricted.

This single protective measure restricting commercial bottom trawling helped to restore seriously depleted populations in these areas. Moreover, protecting areas like Cashes Ledge created the “spillover effect” where larger populations of fish migrate out of the boundaries of the protected area. This is why commercial fishing vessels often “fish the borders” of protected areas.

After a new stock assessment released one year ago showed that populations of cod, haddock and other groundfish were at all time lows, the National Marine Fisheries Service (NMFS) under pressure from some of the largest trawlers in the New England fleet started to hint that allowing bottom trawling in previously protected habitat areas – places like Cashes Ledge – might help to increase falling harvest amounts. At a time of the lowest recorded groundfish populations in history, how does it make sense to increase trawling in the best, remaining habitat areas?

This is why we must urge NOAA to keep our habitat protections in place.

Cashes Ledge is important not only to fish and ocean wildlife but also to scientists hoping to learn about the health and function of New England’s oceans. Many scientists believe that Cashes Ledge represents the best remaining example of an undisturbed Gulf of Maine ecosystem and have used Cashes Ledge as an underwater laboratory to which they have compared more degraded habitat in the Gulf of Maine.

The basic fact is that opening scarce protected habitat in the Gulf of Maine to bottom trawling at a time of historically low groundfish populations is among the worst ideas for recovering fish populations and the industry which depend upon them. But fisheries politics in New England remain. On Dec. 20th the NEFMC may take action through a backdoor exemption process to allow bottom trawling in a large portion of Cashes Ledge and other areas. NOAA needs to keep current protections in place. CLF is committed to securing permanent protection to ensure the long-term health of this important and vulnerable ecosystem. Click here to urge NOAA to protect New England ocean habitat and help ensure a healthy future for New England’s ocean.

Time for Action to Help the Mighty, Important Menhaden

Nov 13, 2012 by  | Bio |  1 Comment »

The most important species are not always the biggest, fastest, or most charismatic. The silvery Atlantic Menhaden usually averages only about 12 to 15 inches in length when it is full grown. But, it’s the massive size of a menhaden school which makes this the most valuable fish you’ve most likely never heard of. Menhaden are among the most important forage species along the Atlantic seaboard and a vital food source for dozens of other species.

For decades the menhaden harvest was among the highest catch in tons of any fishery in the nation, and gross overfishing was a strong concern among other fishermen who understand the menhaden’s valuable role as a forage fish. But this isn’t the first time that menhaden have been in the news or that efforts have been tried to establish a more sustainable fishing level. In a landmark move last year, East Coast fishery managers—responding to a plea for action by more than 90,000 people —committed to advancing new protections for Atlantic menhaden. Now is the time to make sure these plans become real improvements on the water.

Right now we need your help in sending the message that Menhaden need better management! Send a message before Nov. 16th!

Menhaden populations have plummeted 90 percent over the past 25 years and remain at an all-time low—just 10 percent of historic levels. Because these small fish are prey for larger animals, this decline threatens to disrupt coastal and marine food webs and affect the thousands of fishing, whale-watching, and bird-watching businesses that menhaden help support.

We need to leave more menhaden in the ocean to promote their recovery. There is no limit on the total amount of these fish that can be caught at sea. Every year, hundreds of millions of them are ground up to make fertilizer; fish meal for farm animals, pets, and aquaculture; and oil for dietary supplements.

On Dec. 14, the Atlantic States Marine Fisheries Commission will make decisions that are critical to the recovery of Atlantic menhaden and the ocean wildlife that depends on them for food. Let the commission know that it’s time to bring the menhaden fishery into the 21st century.

Please take a few minutes to send a letter to the Atlantic States Fisheries Commission before Nov. 16th!

Or you can do the right thing by writing a letter to Dr. Louis Daniel, vice chair, Atlantic States Marine Fisheries Commission via the ASMFC staff and urge them to:

  • Set an enforceable catch limit;
  • Reduce the overall amount caught each year; and,
  • Follow-through on commitments to restore the menhaden population.

Thank You for your help – now pass it along to your friends!

Atlantic Menhaden are small but vital for a healthy ocean ecosystem

Superstorm Sandy Leaves a Lot of Questions

Nov 2, 2012 by  | Bio |  1 Comment »

The full impact of this hurricane is still becoming known. The storm has taken at least 94 lives, including those of two small boys who were recovered after several days of searching. As a father of two young children this sent a shock wave through my psyche. I feel very fortunate that my extended family and friends along the Atlantic seaboard suffered no more than a power outage and a few lost roof shingles.

As if the floods of early 2010 and Hurricane Irene weren’t enough, the latest photos and news accounts from New Jersey and the New York City area create a smashing realization that the really massive hurricane disasters, the Katrina-like disasters which take years to recover from, aren’t just relegated to the Gulf coast and the Deep South. New England, New Jersey and the other Mid-Atlantic States, and even inland towards the Great Lake states, are all going to have to create new contingency plans for hurricane season.

The immense size and increasing ferocity of the storm’s descent on New England could be both felt and measured. On Monday afternoon a little before 1:00pm the wave height at Cashes Ledge, as indicated by its resident weather buoy 80 miles off the coast of Portland, registered 15.1 feet. About one hour later the wave height was up past 23 feet. This was about the time the trees outside my office in Washington DC started to shed small branches and the same time I’m on the phone with colleagues in Boston over 400 miles away and we are all experiencing the same storm. Do the effects of climate change create a storm such as Sandy or only increase its size and strength? Is that even a pertinent question anymore?

After a decade and a half of the issue of climate change slipping further off the edge of the political and public debate, we see media outlets this week claiming its resurgence. Bloomberg Businessweek gets the full story. The Washington Post has two columnists noting that the climate change issue is back. And, is if timed to make a couple of points, Mayor Bloomberg himself made climate change the centerpiece of his endorsement of the President. Will Sandy really help shift the dialogue, or will the climate deniers and polluters just double down?

Our reaction in the wake of the Superstorm can provide a clear indication of the future and how quickly we can embrace a more realistic, mature approach to crisis management and recovery. Can we start with an honest assessment and some better planning? Or are we going to be stuck – still – in the blatantly self-serving political posturing that avoids real measures to address climate change and its exceptionally well-predicted impacts? There are number of us in New England who both love the ocean and love to use it, and believe that better scientific information and a better process to site new and replaced infrastructure is a great direction to go. We need to develop clean energy sources. We need a healthier ocean and protected habitat. We need existing and new coastal businesses and ocean industries.  The National Ocean Policy is now ready for full implementation. Is there better time to start?

Providing Ocean Beauty, Health, and Wealth Demands NOAA Leadership

The beauty, health, and wealth provided by the productivity of New England’s ocean is illustrated in the diversity of ocean and coastal habitat found in the Gulf of Maine, Georges Bank, southern New England waters, and the far edge of the Outer Continental Shelf. New England’s ocean habitats provide a huge economic service, but only if the underlying ecological foundation is healthy and sustained. Pushing our ocean waters to produce more fish and seafood than is sustainable can lead to a severe decline in goods and services – as we are seeing with the most recent groundfish depletion crisis – or even to an unrecoverable collapse as has happened in eastern Canada.

There are really two major components to a healthy ocean: don’t take out too much in the way of fish and other living resources and don’t put in too much in the way of runoff, nutrients, carbon dioxide, and other pollutants. In New England’s celebrated cod and groundfish fishery we have clearly been taking out too much through decades of overfishing. The National Oceanic and Atmospheric Administration (NOAA), at the request of the New England Fishery Management Council, has for years taken the riskiest possible approach to managing fish stocks. NOAA and the Fishery Management Council have set catch limits at the highest levels allowed by law and then shown great surprise when fish stocks fail to recover.

We need NOAA to show proactive leadership by ensuring a more precautionary approach to setting annual catch limits and to rebuilding fish populations. Decades of unsustainable catch levels should not continue to plague New England’s fisheries or our ocean’s health.

The other problem of overfishing is that the methods used to catch fish have gotten more destructive. Since the development of more powerful engines and sonar during World War II, fishing vessels can go farther out to sea, fish in deeper water, and drag heavier bottom trawls. These inventions not only catch a lot more fish, but also cause more damage to ocean bottom habitat – the kelp beds, boulders and rocky fields, tube worms, anemones, sponges, corals, and mussel beds which serve as nurseries and spawning areas. Over decades we are left with cumulative impacts to large areas of New England’s ocean habitat.

This makes the remaining special areas such as Cashes Ledge even more important as a place where small fish can grow and become large enough to reproduce.

In New England, NOAA is headed in reverse on its legal responsibility and the ecological necessity to further protect juvenile groundfish in their nursery grounds. The commercial fishing industry, led by big trawlers, has argued for opening these nursery grounds. Areas of sea bottom that provide essential fish habitat must be protected from destructive fishing practices like trawling and dredging.  For nearly a decade regional fishery managers have failed to take serious action to protect essential fish habitat.  It’s time to make habitat conservation a priority.

The Conservation Law Foundation, our conservation partners, marine scientists, fishermen, and ocean users agree that permanent habitat protection is needed for Cashes Ledge and other special places.

Waves of Change: Taking on the Threat of Ocean Garbage

Sep 13, 2012 by  | Bio |  1 Comment »

Trash on a New England beach

Walking the sandy beaches of the Cape and Islands, kayaking the marshes and salt ponds, or scrambling around the rocky shores of Maine will almost always provide three things: a great outdoor experience, a chance to explore and learn about nature and the amazing diversity of life, and a full review of the waste, refuse, garbage, and pollutants that we cast onto our rivers, shores, and oceans.

While being blessed with the chance to take a recent early morning hike around my favorite little Massachusetts island, I calculated an assortment of the following: the smashed remnants of dozens of lobster traps, several plastic and metal buckets, beer cans, more beer cans, an unopened plastic bottle of cranberry juice (I didn’t try to drink it), a refrigerator door which was probably 30 years old, plastic food wrappers, auto oil filters, boat oil filters, one pretty large piece of fiberglass part from someone’s unfortunately lost vessel, dozens of miles of discarded fishing line, nets and other assorted fishing gear, flip-flops, sandals and shoes, 50 gallon drums, an unused emergency smoke bomb, about two dozen assorted rubber gloves (mostly lefts), about one dozen assorted rubber boots (mostly rights), a vast amount of the highly predictable but still depressing plastic bottles, a few glass bottles, an oddly-placed large chunk of asphalt, a metal chair, some random pieces of wood pallets and tree stumps, two umbrellas, pesticide spray bottles, one display of typical latex birthday party balloons, and two separate displays of very fancy Mylar celebratory balloons.

While shocking in its abundance, it was still a fairly standard composition of junk. Policy makers refer to this aspect of ocean management as “marine debris.” Honestly, I think we can just call it “ocean garbage.” Ocean garbage is a longtime and ever increasing problem. The type of materials we put into waterways and on our beaches in the modern era tend to be more toxic and long-lived than the flotsam and jetsam of past centuries. The debris floating across the Pacific from the terrible tsunami that devastated the coast of Japan last year has brought some attention to the problem, as has the media report so the massive garbage patches. Believe it or not, even the thousands of tons of stuff from a single event such as the tsunami is dwarfed by the annual build-up of daily deposits.

There are some good folks, however, who are not going to take this problem lying down. One tremendous collaborative effort is the annual International Coastal Cleanup which is organized each year by our good friends at the Ocean Conservancy. The 2012 ICC, as it is known, happens this Saturday, Sept. 15. Thousands of people around this country and others will volunteer for a day to gather up the coastal and ocean garbage and responsibly deposit it in landfills. You can help out too!

A challenge this broad really does require broad coordination and collaboration. The National Ocean Policy provides the forum for state officials, federal agencies, municipalities and other ocean user groups to help tackle the threat of marine debris. Regional ocean planning is certainly a great tool for coordination in New England.
