Oceana Twists Truth to Further Agenda

 

Oceana’s Geoff Shester recently penned an op-ed in The Santa Cruz Sentinel alleging that forage fish harvesting is out of control and must be reigned in.  The only problem with his opinion:  the “facts”.  They are, in fact, not accurate, but instead reflect an agenda.

Below, I’ve highlighted Mr. Shester’s false claims and followed them with a dose of reality:

 

• “Thirty years ago forage species accounted for 40 percent of California’s commercial fish landings by weight.  Today, with big fish gone, forage landings have soared to 85 percent”

In 1981, a moratorium was in effect prohibiting sardine fishing, and tunas dominated California landings, totaling more than 40 percent of the California catch.  The tuna canning industry based in San Diego, then the tuna capitol of the world, was driven out of California beginning in the mid-1980s, due in large measure to unfair competition from foreign water-packed imports and the excessive cost of doing business in the Golden State.  Those ‘big fish’ weren’t gone from the ocean, however, they were just not landed in California.

The sardine resource made a dramatic recovery beginning in the late 1970s, with the advent of a warm-water oceanic cycle.  Resource managers reopened the fishery in 1985, but this time around, they enacted strict harvest limits coupled with environmental triggers.  The resource was declared fully recovered in 1999 when the population exceeding one million metric tons.  But the harvest rate was capped at 10 percent after subtracting 150,000 mt off the top of the biomass estimate to account for forage needs.  The stock appears to have entered another natural decline and biomass estimates have dropped sharply.  Which brings up another allegation:

 

“…Overfish the forage and the rest of the marine species are in trouble…but that is exactly what is happening in California today.  Pacific sardines have declined 70 percent in the past decade, and market squid are being fished at record levels.  California fisheries, like salmon, rockfish and tuna, are depleted and in dire need of recovery.”

Regarding sardine, the conservative biomass estimate does not measure transboundary stocks in Canada and Mexico, but it does count landings from those countries, and those have declined; but coastwide harvest guidelines, including Washington and Oregon, as well as California, have also declined precipitously – from 152,000 mt in 2007 to 40,000 mt in 2011.

The market squid statement also is calculated to confuse.

California’s ocean has exhibited incredible productivity in the past two years, producing the highest grey whale count on record, resurgent rockfish stocks and a rebounding salmon fishery.  Market squid also thrived in these productive ocean conditions, but the fishery did not hit ‘record levels’.  In fact precautionary management has established a maximum harvest cap, intended to prevent overexploitation.  The fishery reached it and was closed before the end of the year.  A post-season survey of the squid spawning grounds revealed large aggregations of squid spawning nearly everywhere, well beyond end of the normal spawning cycle.

The squid life cycle runs from birth to death after spawning in nine short months or less, and abundance is driven primarily by environmental cycles. To maintain a sustainable fishery, The Department of Fish and Game instituted weekend fishing closures, allowing squid to spawn untouched for 30 percent of the week, and implemented marine reserves in more than 30 percent of traditional fishing grounds in central and southern California.  In addition, the fishery management plan approved in 2004 reduced the fleet by more than half.

California fisheries are by no means depleted, they are managed strictly by both the state and federal government (that’s why landings have appeared to decline – more fish are left in the ocean!).  Rockfish and salmon are managed under the ecosystem-based fishery management mandate of the federal Magnuson Act, with precautionary annual catch limits to prevent overfishing.

 

• “A recent federal study found that top ocean predators off California have declined by more than 50 percent since 2003.  Removing their source of food is like taking medicine away from the patient.  Traditional fisheries management concentrates on single species …”

The study, presumably the first draft of the “California Current Integrated Ecosystem Assessment”, does not yet include the area south of Point Conception – a critical omission acknowledged by the scientific team.  The draft IEA was submitted to the Pacific Fishery Management Council as an example.  Clearly, with data from a significant part the ocean missing, conclusions are not ready for ‘prime time’.

The IEA was developed to assist the Council in developing its Ecosystem-based Management Plan for the entire California Current – which will inform all the other fishery management plans, which now include ecosystem considerations themselves.  (The Coastal Pelagic Species plan has considered forage needs for more than a decade!)

Similar innuendos and misstatements run throughout the article, but I will touch on just one more:

 

“The question of fishing sustainably is a matter of political will.  That’s why a strong coalition of conservationists, fishermen and seafood businesses that want to see … healthy California oceans are supporting Assembly Bill 1299 that emphasizes the critical role that forage species play…”

A vast majority of California’s fishing communities, including municipalities, port districts, recreational and commercial fishing groups and individuals, seafood companies and knowledgeable fishery scientists, believe California already fishes sustainably;  indeed, California Current fisheries are acknowledged as having one of the lowest harvest rates in the world.

This super-majority is very much opposed to AB 1299, seeing that it embodies the same type of confusing, captious policy statements as contained in the ‘forage fishing must be controlled’ article.

To be clear, the majority of California fishing-related interests oppose the bill for the following reasons:

 

  • A multi-million dollar boondoggle:  AB 1299 is a solution in search of a problem.  This bill fails to acknowledge and integrate all the existing protections for forage species that now exist in both state and federal law. Whales, sea lions, and sea birds are thriving, providing clear evidence that state and federal forage species policies are working. Moreover, there are no ‘reduction’ fisheries in California, nor fishmeal plants, so the alleged threat from increasing forage fish production for aquaculture does not exist here: fisheries are strictly regulated.

  • Fails to recognize existing efforts: California has done a good job managing forage fish – far better than most other states and countries.  In addition to strict harvest rates and other management measures, the Marine Life Protection Act has implemented no-take reserves, including many near bird rookeries and haul out sites to protect forage for other marine life.  To start as if from scratch is both redundant and disrespectful of that management history.

  • Requires non-existent funding and staff time: Department of Fish & Game (DFG) is already enormously underfunded and understaffed for its existing tasks. The increased demand for Department research and management resources that this bill would create cannot be met without sacrificing resources for programs that are actually necessary.

  • Duplicates federal and state efforts: Oceana, the bill author, admitted at a public forum that California’s Marine Life Management Act already provides a science-based process to manage forage species. The federal Pacific Fishery Management Council is currently developing its California Current Ecosystem Management Plan, which will cover the entire West Coast, not just California state waters, with objectives similar to those in AB 1299. We encourage California to collaborate with the PFMC, which does not require legislation.

  • Places impossible standard on fisheries: The May 27 amendments to AB 1299 camouflage the millions needed to do specified research and make findings, yet still require new fishery management plans and amendments to fishery plans to be consistent with the new policy after January 1, 2012.  The new policy objective requires ecosystem-based management that “recognizes, prioritizes, accounts for, and incorporates the ecological services rendered by forage species”.  This implies setting explicit allocations for birds and mammals off the top of all fishery harvest plans  – and much of this information is not available.  Although final amendments in Appropriations Committee removed specific language, the threat of restriction is still inherent in this policy.

 

AB 1299 still requires millions in new money for DFG to prove that a fishery had no negative impacts before allowing it to operate. This is money that could be going to schools, health care, and other state programs with proven needs.

 

  • AB 1299 does not consider best available science, and could actually impede ecosystem-based management. AB 1299 will not protect forage species as virtually all range far beyond California state waters, but the policy proposed in this bill could severely restrict California fishermen unnecessarily and unfairly.

Anchovy, sardine populations not at risk

The Santa Cruz Sentinel recently ran a column by D.B. Pleschner, executive director of the California Wetfish Producers Association.  It’s reproduced in its entirety below:

By D.B. Pleschner

“In Monterey Bay, and around the world, little fish are in big trouble,” wrote Sascha Zubryd in her May 13 Sentinel article.

The article reported on a new study by Stanford researchers, who expressed surprise that small coastal pelagic fish, such as sardine and anchovy, were as subject to collapse as large predator fish.

But this isn’t news to scientists well-versed in the cycles of these coastal pelagic species. In fact, the first academic research paper that said essentially the same thing appeared in the 1880s, more than 100 years ago.

What’s more, in California, these species are not in trouble.

When asked about the Stanford study, Dr. Richard Parrish, a former member of the West Coast Coastal Pelagic Species Management Team and recently retired from the National Marine Fisheries Service, said, “I am always amazed when academic scientists publish papers on fisheries and are surprised by things that were well-known and published decades ago in fisheries journals.

“The brief answer is yes, small fishes can be and often are overfished,” he added. “The problem is confounded with environmental fluctuations that occur with a periodicity which suggests that you can believe what your grandfather tells you, but you cannot believe what your father tells you.”

Sardines are a classic example.

The storied Pacific sardine collapse in the 1940s was widely blamed on overfishing, but decades later scientific studies of core samples taken from the deep anaerobic trench in the ocean off Southern California revealed layers of sardine scales and layers of anchovy scales corresponding with oceanic cycles. Warm-water cycles favored sardines and cold-water cycles favored anchovies. The bottom line: the sardine population would have declined even without fishing pressure.

Such findings led Dr. Parrish and other members of the management team to design a new, ultra precautionary harvest strategy for sardines when the population was declared fully recovered in 1999.

And the same precautionary principles apply to other coastal pelagic stocks as well, in light of their known cycles of abundance and importance in the ecosystem as forage for other marine life.

Today’s fishery management of coastal pelagic species in California and along the West Coast portion of the California Current Ecosystem is acknowledged as the most precautionary in the world, one of only a few areas deemed to be “sustainable” by internationally recognized scientists Rebuilding Global Fisheries, Science 2009.

The basic management strategy adopted a decade ago for coastal pelagic species harvested in California and on the West Coast maintains at least 75 percent of the fish in the ocean to ensure a resilient core biomass. And the protection rate for sardines is even higher — about 90 percent.

In addition, the state of California is implementing a network of no-take marine reserves throughout state waters. Reserves established at specific bird rookery and marine mammal haul-out sites, for example near Año Nuevo, the Farallon Islands, and the Channel Islands in Southern California, are explicitly intended to protect species such as anchovy, sardines and market squid as forage for other marine life.

Recently, concern over increased utilization of small fishes worldwide has grown in response to a perceived increase in demand for fishmeal for an expanding aquaculture industry.

But again, this risk does not apply to California, as reduction fisheries and fishmeal plants no longer exist in the Golden State.

In Monterey and California overall, people can rest assured that the little fish are not in trouble here; rather these coastal pelagic species are harvested sustainably, and they still contribute enormous benefits to the socio-economic and cultural well-being of our harbor communities.

Fishery Landings by West Coast County, 2006-2010

Maps were created (view pdf) that present rankings by west coast counties according to the major “management groups” (grouping individual species codes) used in the PacFIN database in terms of ex-vessel revenue for the recent 5-year period, 2006-2010.

These management groups accord with the four Pacific Council fishery management plans (coastal pelagic species, groundfish, highly migratory species, and salmon) and four additional categories (crab, other, salmon, shellfish, and shrimp).

The data were obtained by a query grouping landings by county codes in the database. The PacFIN county codes were then matched to FIPS county codes for use in ArcGIS. (The PacFIN county table includes several codes that are not counties, e.g., “Columbia River below Bonneville Dam.”

In data preparation revenue for all these codes were grouped into a single record, which is not displayed in the figures or the table below.)

Counties were used as the geographic units for two reasons. First, counties are a useful geographic unit for producing choropleth maps. Second, grouping by county makes it easier to compare landings data to demographic data (available from the census or other sources) in future analyses.

Biodiversity Loss in the Ocean: How Bad Is It? [research paper]

Coral and fishphoto © 2009 gorfor | more info (via: Wylio)

Science 1 June 2007:
Vol. 316 no. 5829 pp. 1281-1284
DOI: 10.1126/science.316.5829.1281b

The Research Article Impacts of biodiversity loss on ocean ecosystem services By B. Worm et al. (3 Nov. 2006, p. 787) projects that 100 of seafood-producing species stocks will collapse by 2048.

The projection is inaccurate and overly pessimistic.

Worm et al. define collapse as occurring when the current year’s catch is <10 of the highest observed in a stock’s time series. However, fish catch is rarely an adequate proxy for fish abundance, particularly for rebuilding stocks under management. A variety of biological, economic, and social factors and management decisions determine catches; low catches may occur even when stocks are high (e.g., due to low fish prices or the effects of restrictive management practices), and vice versa.

The inadequacy of Worm et al.‘s abundance proxy is illustrated by the time series of data for Georges Bank haddock (Melanogrammus aeglefinus). The highest catch for haddock occurred in 1965 at 150,362 tons (1). This catch occurred during a period of intense domestic and international fishing (1).

In 2003, haddock catch was 12,576 tons, or 8 of the time series maximum. Under the Wormet al. definition, the stock would be categorized as collapsed in 2003. However, stock assessment data (1) estimate the total magnitude of the spawning biomass in 2003 to be 91 of that in 1965. Comparing the estimate of spawning stock biomass in 2003 to the level producing maximum sustainable yield (MSY), the stock was not even being overfished in 2003 (2).

One Fish, Two Fish, False-ish, True-ish

By FELICITY BARRINGER

Two University of Washington scientists have just published a study in the journal Conservation Biology in collaboration with colleagues from Rutgers University and Dalhousie University arguing that the gloomiest predictions about the world’s fisheries are significantly exaggerated.

The new study takes issue with a recent estimate that 70 percent of all stocks have been harvested to the point where their numbers have peaked and are now declining, and that 30 percent of all stocks have collapsed to less than one-tenth of their former numbers. Instead, it finds that at most 33 percent of all stocks are over-exploited and up to 13 percent of all stocks have collapsed.

It’s not that fisheries are in great shape, said Trevor Branch, the lead author of the new study; it’s just that they are not as badly off as has been widely believed. In 2006, a study in the journal Science predicted a general collapse in global fisheries by 2048 if nothing were done to stem the decline.

The work led by Dr. Branch is another salvo in a scientific dispute — feud might be a better word — that pits Dr. Branch and his co-author Ray Hilborn at the University of Washington’s School of Aquatic and Fisheries Sciences and their allies against scientists at the University of British Columbia and their partisans.

Study: Rebuilding Global Fisheries

By Boris WormRay Hilborn et al.

After a long history of overexploitation, increasing efforts to restore marine ecosystems and rebuild fisheries are under way. Here, we analyze current trends from a fisheries and conservation perspective.

In 5 of 10 well-studied ecosystems, the average exploitation rate has recently declined and is now at or below the rate predicted to achieve maximum sustainable yield for seven systems.

Yet 63% of assessed fish stocks worldwide still require rebuilding, and even lower exploitation rates are needed to reverse the collapse of vulnerable species. Combined fisheries and conservation objectives can be achieved by merging diverse management actions, including catch restrictions, gear modification, and closed areas, depending on local context.

Impacts of international fleets and the lack of alternatives to fishing complicate prospects for rebuilding fisheries in many poorer regions, highlighting the need for a global perspective on rebuilding marine resources.

Impacts of Biodiversity Loss on Ocean Ecosystem Services [research article]

By Boris Worm, et al.

 

Dr. Boris Worm

Human-dominated marine ecosystems are experiencing accelerating loss of populations and species, with largely unknown consequences.

We analyzed local experiments, long-term regional time series, and global fisheries data to test how biodiversity loss affects marine ecosystem services across temporal and spatial scales. Overall, rates of resource collapse increased and recovery potential, stability, and water quality decreased exponentially with declining diversity.

Restoration of biodiversity, in contrast, increased productivity fourfold and decreased variability by 21%, on average.

We conclude that marine biodiversity loss is increasingly impairing the ocean’s capacity to provide food, maintain water quality, and recover from perturbations. Yet available data suggest that at this point, these trends are still reversible.

Congress Defunds Wasteful Catch Shares Program

Washington, DC – In a big victory for commercial and recreational fishermen, the U.S. Congress on April 14 voted to defund the “catch shares” program, a controversial and wasteful fisheries management fiasco.

Wenonah Hauter, Executive Director of Food & Water Watch, said the program has been “blocking access to fish for thousands of smaller scale fishermen, destroying their livelihoods and our coastal and fishing communities.”

The widely-contested “catch shares” program on the East and West Coasts, a pet project of Dr. Jane Lubchenco, NOAA administrator and also under secretary of commerce for oceans and atmosphere, serves to privatize public trust resources by concentrating ocean fisheries in a few corporate hands.

This amendment, offered by Representative Walter Jones of North Carolina, is part of the FY2011 budget that President Barack Obama signed into law on April 15.

Budget measure blocks new catch share programs

NEW BEDFORD — As a budget amendment blocking catch share management from spreading in America’s fisheries makes its way to President Barack Obama’s desk, new concerns have cropped up about the arrival of private brokers of fishing allocations.

The measure in the budget prohibits the Commerce Department from funding the implementation of fisheries catch share programs such as the one imposed in the Northeast one year ago. It was introduced by U.S. Rep. Walter Jones, R-N.C., and backed by U.S. Rep. Barney Frank, D-Mass., among others.

The language in the amendment was softened somewhat in the budget deliberations. Originally, it stopped funding for even the study of new catch share systems. Now it simply prohibits their approval.

“This is a shot in the arm for fishermen and a shot across the bow of the National Marine Fisheries Service,” said Jones in a prepared statement. “The last thing our government should be doing in these economic times is spending millions of taxpayer dollars to expand programs that will put even more Americans out of work. NMFS would be wise to take heed of the opposition of fishermen, the public and the Congress to their catch shares agenda; we’re not going away.”

Catch shares and sector management are being blamed (or credited) with sharply reducing the size of the groundfish fleet in the Northeast and the rapid consolidation of catch into the top 10 percent of the boats. The measures are being challenged in federal court in a lawsuit filed by New Bedford, Gloucester and other fishing interests.

The Road to End Overfishing: 35 Years of Magnuson Act

Assistant Administrator Schwaab for Fisheries Talks about the Cornerstone of Sustainable Fisheries

Handling Samplesphoto © 2010 Deepwater Horizon Response | more info (via: Wylio)

As we look toward Earth Day next week, I want to acknowledge and highlight the 35 th anniversary of the Magnuson-Stevens Fishery Conservation and Management Act. Simply called “the Magnuson Act”, this law, its regional framework and goal of sustainability, has proven to be a visionary force in natural resource management – both domestically and internationally. The Magnuson Act is, and will continue to be a key driver for NOAA as we deliver on our nation’s commitment to ocean stewardship, sustainable fisheries, and healthy marine ecosystems

Because of the Magnuson Act, the U.S. is on track to end overfishing in federally-managed fisheries, rebuild stocks, and ensure conservation and sustainable use of our ocean resources. Fisheries harvested in the United States are scientifically monitored, regionally managed and legally enforced under 10 strict national standards of sustainability. This anniversary year marks a critical turning point in the Act’s history. By the end of 2011, we are on track to have an annual catch limit and accountability measures in place for all 528 federally-managed fish stocks and complexes. The dynamic, science-based management process envisioned by Congress is now in place, the rebuilding of our fisheries is underway, and we are beginning to see real benefits for fishermen, fishing communities and our commercial and recreational fishing industries.

But, we did not get here overnight. Our nation’s journey toward sustainable fisheries has evolved over the course of 35 years. At this particular moment it is important to take time and reflect back on where we have been to understand where we are and fully appreciate the historic visions and strategic investments that got us here, particularly by the Act’s principal architects, the late U.S. Senators Warren G. Magnuson of Washington State and Ted Stevens of Alaska.
