European fishing body takes aim at environmental group

November 14, 2015 — A European fishing body has accused an environmental pressure group of making “misleading and untrue” statements” about the industry in an attempt to influence policy-makers.

The open letter from Europeche – whose members include the Scottish Fishermen’s Federation – is addressed to the Pew Charitable Trusts, which earlier this year published a report called Turning the Tide: Ending Over-fishing in North Western Europe.

“That report contained a number of statements which are demonstrably untrue and contrary to scientific opinion,” Europeche president Javier Garat said yesterday.

He added: “The motives for Pew to publish misleading and untrue statements remain obscure, but this is not a matter of misinterpretation of data or different opinion.

JOHN SACKTON: Media’s Rampant ‘Fisheries Are Going Extinct’ Claim Finally has Serious Rebuttal from Scientists

SEAFOODNEWS.COM [The Editor’s View] by John Sackton — Nov 3, 2015 — The following headline came across our newsfeed this morning “Some South China Sea fish ‘close to extinction'”, courtesy of Agence France Presse.

The report was based on a quote from Rashid Sumaila, director of the Fisheries Economics Research Unit of the University of British Columbia.

“The South China Sea is… under threat from various sources. We need to do something,” said Sumaila.

“The most scary thing is the level of decline we have seen over the years. Some species (are facing) technically extinction or depletion,” Sumaila, who headed the study, told a press conference in Hong Kong.

Having not seen the paper, it is not possible to evaluate his statements. But they are readily taken up because they feed into a media narrative that has proved very hard to change: fisheries around the world are dying because of human greed and overfishing. This narrative has been central to NGO campaigns focused on fisheries.

For many years, there was no organized response, and especially no way for journalists to get accurate scientific information. If they were fed a quote, such as “90% of the worlds stocks were unsustainably harvested” as appeared in Newsweek this summer, or that fish is ‘aquatic bushmeat’ comparable to eating monkeys and rhinoceros, as was said by Sylvia Earle, they have no way to evaluate its truthfulness. No wonder that seafood seems so controversial.

A group of scientists has come together through Ray Hilborn and his colleagues at the University of Washington, that is finally providing real-time commentary and rebuttal – i.e. pointing out the basic science – which in many cases does not support these media stories.

Our companion story today by Peggy Parker has more detail on Hilborn’s rebuttal to Newsweek, where he said one article ‘may set a record for factual errors’.

The idea is not to simply point out poor science and unsupported conclusions, but to encourage media to use their website cfooduw.org, as a resource whenever they see a scientific claim about fisheries.

For example, just in the past few days, scientists from around the world have posted comments on a range of global topics.

Hilborn pointed out, and the Newsweek editors accepted, a correction that not 90%, but 28.8% of fish stocks were estimated as overfished. Would they have run the story if they had not been pitched intitally that 90% of fish stocks have collapsed?

Steve Cadrin of the University of Massachusetts comments on recent articles about cod in both New England and Newfoundland. He says “The lesson from both of these papers is that rebuilding the stocks to historical levels depends both on fisheries management … and on the return of favorable environmental conditions.”

“Stock assessment models are simplifications of a much more complex reality. Stock assessments typically assume that components of productivity (survival from natural mortality, reproductive rates, growth) are relatively constant. These assumptions may be reasonable for relatively stable ecosystems. However, considering the extreme climate change experienced in the Gulf of Maine, such assumptions need to be re-considered. Alternative approaches to science and management are needed to help preserve the fishing communities that rely on Gulf of Maine cod.”

Two tuna scientists collaborate on a story in response to the charge by Greenpeace that John West is breaking its sustainable tuna pledge by buying fish caught with FADs.

FADs are a type of fishing gear (radio monitored fish aggregating devices) that have become very widely used for pelagic tuna. The two scientists, Laurent Dagorn and Gala Moreno, point out in a comment and a recent paper the important issues with FADs are 1) quantifying, with scientific data, how big that impact actually is, 2) determining if the impact is acceptable for the amount and diversity of fish caught, 3) comparing it with the impact of other fishing gears, and 4) implementing measures to reduce an impact if it is too high for the ecosystem, taking into account all fishing impacts.

This provides a real road map for a discussion of FADs and how they should or should not be used, in contrast to the campaign claims that they are simply destructive types of fishing gear. Dagorn and Moreno point out that all food production (including organic farming) involves making choices about modifying ecosystems, and tuna fishing should not be considered in isolation, but in how it meets the goal of providing food for global populations.

Aggregating and making this kind of fisheries science easily accessible is one of the most concrete actions that has been taken in years to counteract the misinformation that so many of us in the industry experience every day.

It is an effort that deserves wholehearted support, including publicizing the resource to local writers and editors. Please visit their website at cfooduw.org.

Climate change fuels cod collapse

November 3, 2015 — The strongest link yet between climate change and the collapse of New England’s cod fish stunningly confirms how global emissions fuel regional calamities. The problems can no longer be contained by fishery council catch limits. They now demand worldwide greenhouse gas solutions.

A team of scientists, including those from the Gulf of Maine Research Institute, the University of Maine, and the Bigelow Laboratory for Ocean Sciences in Maine, found that average surface water temperature in the Gulf of Maine rose four degrees between 2004 and 2013. Temperatures in the gulf have risen faster than in 99 percent of all sea waters, with record warmth recorded in 2012.

Four degrees is trivial to humans, who can shed sweaters or seek shade. But for a cold-blooded fish at the southern edge of its breeding range, unable to turn on the AC against the northward shift of the Gulf Stream, four degrees is a sauna. Less cod larvae survive in warmer water, possibly because their cold-water zooplankton food is also less available. Surviving cod then seek deeper, colder water, where more voracious predators await to compound their mortality.

The study, published last week in the journal Science, helps explain why cod stocks have not rebounded under draconian federal catch limits. Adding in the negative impact of warmer water, researchers found that fishing mortality was far too high to rebuild stocks even when fishermen did not exceed quotas.

Inside North Carolina Science: DNA markers track fish migration

November 1, 2015 — On a cloudy spring day last year, I had the opportunity to go out on the Roanoke River with biologists from the North Carolina Wildlife Resources Commission. I collected fish with them as part of my job as a geneticist at the N.C. Museum of Natural Sciences. We work in conjunction with NCWRC and use genetics to track and manage stocking programs for American shad, a native fish currently in decline.

In an effort to bring American shad back to traditional population numbers, NCWRC goes out on the Roanoke and Neuse rivers every spring to collect adult American shad returning to spawn. These fish are taken to hatcheries to spawn; eggs are allowed to hatch safely without being eaten by the predators that share their river ecosystem. The baby fish, called fry, are then released back into the river. In the fall, NCWRC goes back onto the rivers to see how many juvenile fish they can find.

NEFMC: Response to Study on Rising Water Temps in the Gulf of Maine

October 29, 2015 — The following was released by the New England Fishery Management Council:

The Gulf of Maine, located off northern New England and Canada, has hosted important commercial and recreational marine fisheries for centuries. In addition to existing threats from land-based pollution, marine discharges, energy development, and disturbances to habitat, a more recent problem, temperature rise, has emerged. The just-published paper in Science —Slow Adaptation in the Face of Rapid Warming Leads to the Collapse of Atlantic Cod in the Gulf of Maine — adds to the increasing body of work on this topic.

As an organization responsible for the management of fisheries in federal waters that encompass the Gulf of Maine, the New England Fishery Management Council (Council), along with partners, NOAA Fisheries and the New England states, offers comments on this paper.

Most importantly, climate change is a very real issue that affects fisheries in ways we are just beginning to understand and is one the Council and others must confront.

This particular paper presents interesting research, but as is generally the case, it is rare that any one scientific study provides “The Answer.” This one will almost certainly generate more discussion and further consideration of how fisheries management bodies might respond.

NOAA’s Northeast Fisheries Science Center is actively investigating climate change that could help develop possible responses. The Science paper will likely become part of the larger discussion on how to adapt and respond to climate change. During that process, it will be the subject of careful review, including testing of its assumptions and conclusions. Should they stand up to this scrutiny, the work may influence future quota-setting

Work is underway by the Council to look more broadly at fisheries through ecosystem-based fisheries management; those efforts may illuminate the way in which we consider this pressing threat to the productivity of fisheries in the Gulf of Maine and elsewhere.

More critically, the Science paper appears to presume that the Council should have anticipated the unusual temperature rise in 2012, without any explanation of how that could have been done. The current quota for Gulf of Maine cod is the lowest on record, and will almost certainly remain so in the foreseeable future. The goal at this time is to allow sustainable levels of fishing on healthy stocks, such as haddock, redfish, and pollock to continue, while creating the opportunity for cod to recover.

After reviewing the paper, Council Executive Director Tom Nies summarized his reaction to the challenges raised in the Science paper. “Fishery managers will need to adapt to the host of significant changes caused by the rapid rise in water temperatures in the Gulf of Maine; specifically, the New England Council will continue its close partnership with the scientific community in order to mount an effective response to this circumstance.”

Cod Could Recover in Warming Waters

October 28, 2015 — The first clue came in 2008, recalled George Rose, a marine biologist at Memorial University of Newfoundland, when he saw the cod aggregating in large numbers offshore during the spawning season. It was a sight he had sorely missed in 15 years. In the early 1990s, cod fisheries suffered such a dramatic collapse that they emerged as an aquatic poster child for fisheries mismanagement, according to Rose.

In a paper published yesterday in the Canadian Journal of Fisheries and Aquatic Sciences, Rose and his colleague, Sherrylynn Rowe, document the comeback of the Atlantic cod off Newfoundland and Labrador over the past decade. The fact that they have shown that the cod stock there is on the way to recovery is good news, Rose said, as “it shows that it is not all gloom and doom.”

Their study attributed the recovery to improved environmental conditions, better fish management and the availability of an important food source, capelin, whose populations also fell drastically in the early 1990s and have recently bounced back, too. The rebound of Atlantic cod in this region contrasts with their rapidly declining populations off the northeastern coast of the United States, where until last year the stocks remained significantly below sustainable levels. Previous research has associated this persistent population slump with the pressures of overfishing and also warming waters. The warming temperatures, however, seem to be favoring a cod fishery revival in Newfoundland and Labrador, or at least not hampering its recovery.

Fish Success Story: Cod Makes a Comeback

October 27, 2015 — The cod is coming back.

The species that was for centuries a mainstay of the American and Canadian economies had virtually vanished off the Northeastern North American coast by the 1990s owing to overfishing. That led regulators in 1992 to impose a moratorium on cod fishing.

It appears to have worked.

New research shows that cod biomass has increased from the tens of tons to more than 200,000 tons within the last decade. This spring, scientists documented large increases in cod abundance and size for the first time since the moratorium in the more northerly spawning groups, according to a study published Monday in the Canadian Journal of Fisheries and Aquatic Sciences.

“Cod was historically one of the most important fish stocks in the world,” said George Rose, director of the Center for Fisheries Ecosystems Research at the University of Newfoundland in Canada and author of the new report on the cod’s recovery. “When the stocks collapsed in the 1990s, it became the icon of all the bad things we are doing to the ocean, and in many ways, it changed how we deal with our oceans worldwide.”

The Great Northern Cod Comeback

October 27, 2015 — Once an icon of overfishing, mismanagement, and stock decline, the northern Atlantic cod is showing signs of recovery according to new research published today in the Canadian Journal of Fisheries and Aquatic Sciences.

This research, led by Dr. George Rose, tracks what is arguably the most important comeback of any fish stock worldwide. Studying the great northern Atlantic cod stock complex off Newfoundland and Labrador, once considered among the largest cod stocks in the world before its disastrous decline in the 1990s, Dr. Rose documents the stock’s rebound over the past decade from tens of thousands to several hundred thousand tonnes and growing.

NILS STOLPE: So how’s that “catch shares” revolution working out for groundfish?

FishNet USA/October 22, 2015 — NILS E. STOLPE — Most of you probably remember when newly appointed NOAA head Jane Lubchenco went to New England and announced that she was going to save our nation’s oldest fishery. But if it didn’t make a lasting impact on you, quoting from the Environmental Defense blog, EDFish by Tesia Love on April 8, 2009, “Sally McGee, Emilie Litsinger and I got to witness something pretty wonderful today. Jane Lubchenco came to the New England Fishery Management Council meeting to announce the immediate release of $16 million to the groundfish fishery to help move the fishery to ‘sector” catch share management by providing funding for cooperative research to help fishermen get through a tough fishing year with very strict limits on fishing effort.” She went on to quote Dr. Lubchenco “we need a rapid transition to sectors and catch shares. Catch shares are a powerful tool to getting to sustainable fisheries and profitability. I challenge you to deliver on this in Amendment 16, to include measures to end overfishing. I will commit the resources to my staff to do their part to ensure Amendment 16 is passed in June. We are shining a light on your efforts and we will track your progress. There is too much at stake to allow delay and self-interest to prevent sectors and ultimately catch shares from being implemented.”

I’m sure that you were there with the rest of us, heaving a huge sigh of relief with visions of Dr. Lubchenco on her shiny white steed, first riding to the rescue of the New England fishery, and then on to all of the rest of our struggling fisheries. “Hyo Silver! Away!”

So how did she do? A couple of years back NOAA/NMFS released the 2012 Final Report on the Performance of the Northeast Multispecies (Groundfish) Fishery (May 2012 – April 2013). It’s available at http://www.nefsc.noaa.gov/publications/crd/crd1401/. The report included a table – available at http://www.nefsc.noaa.gov/publications/crd/crd1401/tables.pdf – included a table titled Summary of major trends (May through April, includes all vessels with a valid limited access multispecies permit) for the fishing years 2009 to 2012. The table only takes up a single page, is pretty easily understood and is well worth your consideration in its entirety but I’ll take the liberty of synopsizing what I think are the major points it illustrates. In each of the four years the groundfish revenues, landed weight, number of active vessels that took a groundfish trip, the total number of groundfish trips, and the total crew days on groundfish trips decreased. The non-groundfish revenues and landed weight increased. The days absent on a non-groundfish trip increased slightly then decreased.

And then we come to 2013 (it seems that according to NOAA/NMFS, 2014 hasn’t gotten here yet). Had the myriad benefits of Dr. Lubchenco’s and her ENGO/foundation cronies’ Catch Share Revolution finally arrived? Apparently, not quite yet. According to the 2013 Final Report on the Performance of the Northeast Multispecies (Groundfish) Fishery (May 2013 – April 2014), just about everything that was falling in FY 2009 to 2012 continued to fall in FY 2014. I won’t go over any of the details, but the corresponding Table 1 for that year is available at http://www.nefsc.noaa.gov/read/socialsci/pdf/groundfish_report_fy2013.pdf.

Oh well, I guess she deserves a few points for trying – and we shouldn’t forget that before she could really focus on fixing groundfish she was distracted by having to dump a couple of millions of gallons of Corexit into the Gulf of Mexico.

Thirteen species are included in the New England Fishery Management Council’s multi-species fishery management plan, the “groundfish” FMP. Four of those species support no or minimal directed fisheries. The landings of those that support a significant commercial fishery are in the table below (from the NOAA/NMFS commercial landings database). Looking at these data, it’s impossible to suggest that after years of intensive management this management regime is anything that could be considered a success – unless your idea of success is putting a whole bunch of people out of work. In fact only the most charitable among us could term it anything other than disaster – and it’s a disaster that has been in the making since long before Dr. Lubchenco so fatuously announced that she was going to fix it.

(I’ll add here that catch share management is not a cure-all for all that’s wrong with fishery management nor is it the reason for management failures – though at the time Dr. Lubchenco and her “team” apparently believed it was. It is nothing more than an option for dividing the catch among users. As such it can have profound socioeconomic impacts on participants in the fishery and on fishing communities that depend on it, but not on the fishery resources themselves.)

How might it be fixed? In the original FishNet article I quoted a couple of paragraphs from a National Academy of Sciences study Evaluating the Effectiveness of Fish Stock Rebuilding Plans in the United States (available at http://www.nap.edu/catalog/18488/evaluating-the-effectiveness-of-fish-stock-rebuilding-plans-in-the-united-states). I can’t think of anything more valuable than repeating those words here. On page 178 of the report the authors concluded “the tradeoff between flexibility and prescriptiveness within the current legal framework and MFSCMA (Magnuson-Stevens Fishery Conservation and Management Act) guidelines for rebuilding underlies many of the issues discussed in this chapter. The present approach may not be flexible or adaptive enough in the face of complex ecosystem and fishery dynamics when data and knowledge are limiting. The high degree of prescriptiveness (and concomitant low flexibility) may create incompatibilities between single species rebuilding plans and EBFM (Ecosystem Based Fisheries Management). Fixed rules for rebuilding times can result in inefficiencies and discontinuities of harvest-control rules, put unrealistic demands on models and data for stock assessment and forecasting, cause reduction in yield, especially in mixed-stock situations, and de-emphasize socio-economic factors in the formulation of rebuilding plans. The current approach specifies success of individual rebuilding plans in biological terms. It does not address evaluation of the success in socio-economic terms and at broader regional and national scales, and also does not ensure effective flow of information (communication) across regions.”

In other words, the fishery managers need more informed flexibility to adequately manage our fisheries. It has been the goal of the fishing industry’s friends in Congress to provide this necessary flexibility (with adequate safeguards, of course). Conversely it has been the goal of a handful of foundations and the ENGOs they support and a smaller handful of so-called fishermen’s organizations to prevent this, and it seems that they have been willing to resort to just about any tactics to do it. As they have been successful in their efforts the fishing industry has continued to lose infrastructure that will never be replaced and markets that will be next to impossible to recover – and the percentage of imported seafood that we consume will continue to increase in spite of the fact that our fisheries are among the richest in the world.

Maine Is Literally Dropping Fish Out of Low-Flying Airplanes, and It’s Mesmerizing

October 21, 2015 — Video of a man “aerial dropping” live fish into a pond from a low-flying plane has become a minor sensation after the footage was uploaded to the Facebook page of the Maine Department of Inland Fisheries and Wildlife. The video has so far gotten more than 25,000 views.

“The department annually stocks over 1 million fish throughout the state, utilizing a variety of methods that include flying fish by airplane into remote ponds,” the department wrote in the video description. “The fish are loaded into tanks that are attached to the pontoons on the aircraft, stocking locations are verified and then the planes take off. The tanks are then emptied when flying over the water. The department generally stocks over 180 waters each year by airplane.”
