Acidifying Oceans Could Spell Trouble for Squid

Acidifying oceans could dramatically impact the world’s squid species, according to a new study led by Woods Hole Oceanographic Institution (WHOI) researchers and soon to be published in the journal PLOS ONE. Because squid are both ecologically and commercially important, that impact may have far-reaching effects on the ocean environment and coastal economies, the researchers report.

“Squid are at the center of the ocean ecosystem—nearly all animals are eating or eaten by squid,” says WHOI biologist T. Aran Mooney, a co-author of the study. “So if anything happens to these guys, it has repercussions down the food chain and up the food chain.”

Research suggests that ocean acidification and its repercussions are the new norm. The world’s oceans have been steadily acidifying for the past hundred and fifty years, fueled by rising levels of carbon dioxide (CO2) in the atmosphere. Seawater absorbs some of this CO2, turning it into carbonic acid and other chemical byproducts that lower the pH of the water and make it more acidic. As CO2 levels continue to rise, the ocean’s acidity is projected to rise too, potentially affecting ocean-dwelling species in ways that researchers are still working to understand.

Mooney and his colleagues—lead author Max Kaplan, then an undergraduate student from the University of St. Andrews in the U.K. and now a WHOI graduate student, and WHOI scientists Daniel McCorkle and Anne Cohen—decided to study the impact of acidifying seawater on squid. Over the summer of 2011, Mooney and Kaplan gathered male and female Atlantic longfin squid (Loligo pealeii) from the waters of Vineyard Sound and transported them to a holding tank in the WHOI Environmental Systems Laboratory. When these squid mated and the females laid their egg capsules—each of which can contain 200 to 300 fertilized eggs—the researchers transferred some of the capsules to one of two smaller tanks filled with Vineyard Sound seawater.

Magnuson Reauthorization must address food, jobs, and revenue, as well as fish says Ray Hilborn

Ray Hilborn is a Professor in the School of Aquatic and Fishery Sciences, University of Washington, and one of the world’s reknowned experts on fisheries. He has long advocated a broad view of the benefits of fisheries in the food system, and asked that we consider the ecological impacts of not fishing as well as those of fishing. This is a guest editorial written following the Managing Our Nation’s Fisheries Conference, held earlier this month in Washington, DC.

The recent Managing Our Nations Fisheries conference in Washington D.C. and the upcoming reauthorization of the Magnuson-Stevens Fisheries Management and Conservation Act has focused attention on the nation’s fisheries, how well they are doing, and what can be done to improve the contribution of U.S. fisheries to our national well-being. A logical first step in evaluation of our fisheries is to first ask what are the objectives of American fisheries management?

The text of the act begins with “To provide for the conservation and management of the fisheries, and for other purposes”, but then becomes more specific by stating that rebuilding fish stocks, ensuring conservation , protecting essential habitat are all intentions of the act. Also, the act makes it clear that one objective is to provide for “the development of fisheries which are underutilized or not utilized … to assure that our citizens benefit from the employment, food supply, and revenue which could be generated thereby.”

Successful Managing Our Nation’s Fisheries Conference Brings Together Diverse Voices

The Managing Our Nation’s Fisheries 3 conference wrapped up today on a successful note, with conference participants developing 128 recommendations for improving fishery sustainability. The draft recommendations are online at http://tinyurl.com/cgugoef and will be further elaborated in the conference proceedings.

The conference was coordinated by the eight Regional Fishery Management Councils and NOAA Fisheries, and was sponsored by both fishing industry and environmental groups. The conference aimed to identify both legislative and non-legislative measures to advance fishery sustainability in light of the coming reauthorization of the Magnuson-Stevens Fisheries Conservation and Management Act, which governs Federal fishery management in the United States. Most participants seemed to agree that the Magnuson-Stevens Act has been successful in managing U.S. fisheries, and that large-scale revisions would not be needed. For example, under the Act, 32 fish stocks that were previously labeled “overfished” have been rebuilt. However, there was also agreement that some changes are needed to keep the Act relevant, flexible, and responsive.

“These recommendations will be considered carefully as we move forward with Magnuson-Stevens Act reauthorization,” said Dave Whaley, Legislative staff for the House Natural Resources Subcommittee. “We do need to act carefully; we do not want to solve problems in one area of the country while creating new problems in other areas.”

The conference, held at the Mayflower Renaissance Hotel in Washington, D.C., began on May 6 with keynotes by Rep.Doc Hastings (R-WA); NOAA Assistant Administrator Eric Schwaab; chef, author and television host Barton Seaver; and Deadliest Catch skipper Keith Colburn. The conference continued May 8 and 9 with sessions on improving fishery management essentials, advancing ecosystem-based decision making, and providing for fishing community stability. Senator Mark Begich (D-AK) addressed the conference attendees on May 8. More than 600 people attended the conference.

House Natural Resources Chairman Hastings Discusses Magnuson-Stevens Act Reauthorization at Fisheries Conference

Today, House Natural Resources Committee Chairman Doc Hastings (WA -04) spoke at the third Managing Our Nation’s Fisheries Conference coordinated by the Regional Fishery Management Councils and hosted by the Pacific Fishery Management Council. During his remarks, Chairman Hastings discussed the reauthorization of the Magnuson-Stevens Act, President Obama’s National Ocean Policy, and the need to update the Endangered Species Act.

The following are highlights from his speech:

Balance and Flexibility

“Managing fish – and fishermen – is a challenge.  It requires balancing act in a number of areas: between a sustainable harvest level and the maximum economic value for the fisheries; between recreational and commercial users of the same resource; between different gear types in the same fisheries; and between the interests of different states.  In addition, not only are the fisheries different, but the challenges are different in each region of the country.  Because of these differences, a one-size-fits-all management structure is not the most efficient structure.

The Magnuson-Stevens Act provides the framework for sustainable fisheries management that allows for regional solutions to address regional challenges.  The Act works, it is absolutely necessary to maintain this authority that allows regions to find unique solutions to their problems.  Because of this framework the United States has arguably the best managed fisheries in the world.”

Magnuson-Stevens Reauthorization

“It is Congress’ responsibility to re-examine and reauthorize the laws that we create and the current authorization for the Magnuson-Stevens Act expires at the end of Fiscal Year 2013. The time for Congress to work on this reauthorization is now.

As Chairman of the Natural Resources Committee – the House Committee with jurisdiction over the Magnuson- Stevens Act – I have already begun the reauthorization process with several hearings in the last Congress and, in March, the first of several hearings we will hold this year. It is my goal is to try and reauthorize this important statute this Congress… We are in the process of scheduling our next hearing on the reauthorization and it will be formally announced soon.  It will be on data collection issues and it will be held on May 21st, but there are other issues that need to be addressed at further future hearings.”

Big environmental push for new fisheries regs slowed at NOAA Managing Fisheries Conference in DC

After three days at the Managing our Nations Fisheries Conference in Washington DC, there is clearly no overriding fisheries reform issue that is going to get resolved quickly through new NOAA or congressional action.

This is a very positive outcome, and reflects a sense of stability about US fisheries management.

First, the conference was extremely well organized, and the full materials are available at the conference website: www.managingfisheries.org.

The overall tone of the conference reflected the success that the 2006 revision of Magnuson has had in setting in place a sustainable approach to US fisheries. There was a recognition that applying harvest limits to virtually all fisheries, and implementing catch share type allocation systems in many fisheries, has had a hugely positive impact on eliminating overfishing, and on reducing bycatch and impacts on non-target species.

However, seven years after the 2006 bill, there are a number of things that the 8 regional management councils would like to see improved.

The conference did not come to any conclusions – but instead the discussions set the stage for the lobbying and back and forth with NOAA, and in Congress, that will result in updates to the National Standards – the enabling language on which the councils act – and on possible changes to the Magnuson bill when the new authorization is achieved.

Changes in NOAAs interpretation of the Act under their regulatory authority are likely to happen far more quickly, and with good result, that the changes to Magnuson Act itself, which will be a monumental multi-year task.

The following are some of the brief issue summaries and positions discussed at the conference.

On “Forage Fish”, Pew’s Peter Baker Misses the Mark

“Forage fish” management in the California Current Ecosystem is the most precautionary in the world. Current ecosystem modeling efforts find that purse seine fisheries for coastal pelagic species harvest less than four percent (or two percent, depending on source) of the planktivorous forage pool.

“According to a paper by Kaplin et al 2012 in Fish and Fisheries. Cumulative impacts of fisheries in the California Current. This paper uses the Atlantis model to look at the effects of the major fisheries (by gear type) on other fisheries and species. The purse-seine fishery has the largest effect on other ecosystem components; almost all of the effects were positive! The purse-seine fishery (for coastal pelagic species) resulted in large increases in the Large planktivores, very little change in the small planktivores (they note that the fishery takes <4% of the small planktovore biomass), increases in salmon, deep-vertical migrators, misc pelagic sharks, large zooplankton, microzooplankton, and nearshore fish.” – Dr. Richard Parrish, retired NMFS fishery biologist in Monterey who has more than 50 years’ knowledge of CPS and the California Current.

—

The paper A Case for Precautionary Management of Forage Fish, presented by Pew’s Peter Baker at the Managing Our Nation’s Fisheries Conference on May 8, is based on several assumptions about “forage fish” and predator species that are unproven. These unproven assumptions, as well as a lack of peer-review of the Lenfest Forage Fish Task Force that the paper extensively cites, should raise significant questions and engender in-depth review before its recommendations become standard practice in fisheries management.

The paper’s recommendations are based around the assumption that “forage fish” is a legitimate and useful categorization of species to be used in fisheries management, and that the various “forage species” can be managed under the same broad guidelines. Specifically, the paper recommends implementing restrictions intended to leave forage species biomass at 75 percent of unfished levels. The paper argues that adopting this conservative management strategy will lead to an increase in the amount of forage available and will benefit predator species.

However, these species have a variety of biological differences, and don’t have much in common outside of their common role in the marine food web. These significant differences–including fecundity, spawning periods, migration, predator-prey relationships, and habitat–are much more relevant variables for fisheries management than a shared trophic role.

‘Mystery fish’ turns out to be 125-pound opah, a rare catch aboard Southern California half-day boat

Anglers and crew aboard a Southern California half-day boat were astonished last week to see what the captain had reeled from the depths: a stunningly gorgeous moon-shaped denizen with a speckled body and bright-red fins.

It was an opah, a species more commonly found in tropical and sub-tropical waters much farther offshore. Opah catches are rare off California, and extremely rare in coastal waters. To have landed one of these pelagic beauties from a half-day boat, within view of the shore, might be unprecedented.

Opah2Capt. Jeff Patrick of the Western Pride hooked the 125-pound opah on a sardine at a depth of about 250 feet, while on a rockfish excursion out of Davey’s Locker Sportfishing in Newport Beach.

The “mystery fish” was so feisty that he thought he had hooked a shark. The fight lasted 45 minutes and at one point the captain contemplated cutting the line because the rockfish had stopped biting and he wanted to relocate to a more productive area.

MIKE CONROY: Squid Fishermen Fight Not ‘David vs. Goliath,’ More Like ‘Boy Who Cried Wolf’

Hearing claims of three squid brail (smaller boat) fishermen, one might think that the larger seine vessel squid fishermen are illegally catching all of the allowable quota.

But that’s just not the case. In fact, not only is there an abundance of squid in California’s waters – more than enough to go around – most of the brail-boat fishing fleet have no problem with the current management structure.

That’s because the squid resource is booming and most fishermen have been catching plenty of squid!

Managing our Nation’s Fisheries Conference looks to be a free for all in Washington DC next week

I will be at the conference, and mostly looking for the underlying assumptions to the arguments being made. The adoption of hard TACs and harvest control limits in the last reauthorization of Magnuson has proved to be a key factor in the success of US fisheries Management. Now the issues seem to turn more on a need for increased flexibility and a recognition that we have moved beyond overfishing, and now should concentrate on maximizing the benefits and maintaining healthy ecosystems.

Those who advocate for increased restrictions – whether in habitat, elimination of fishing gear, or enhanced protection of forage fish, have to make the case as to why, when our fisheries have successfully recovered, we are still being asked to address these issues in a crisis mode.

NOAA issues status of stocks report; overfishing continues to decline in US

SEAFOOD.COM NEWS  by John Sackton May 2, 2013

NOAA released its 2012 status of the stocks report to Congress this morning, showing continued progress in eliminating overfishing and rebuilding stocks in the U.S.

Overfishing declined 30% between 2011 and 2012.  In 2011, 14% of the stocks where NOAA has data were being overfished.  In 2012, that percentage dropped to 10%.

Once overfishing is ended, a stock will typically recover to its MSY biomass.  Stocks are classified as overfished when they are below the level needed to sustain harvests at the Maximum sustainable yield level.  The number of stocks classified as overfished dropped from 21% to 19%, a decline of 10%.

Acting Assistant Administrator for NOAA Fisheries Sam Rauch said “It was another record-setting year for  our marine fisheries. Today, we are reporting that six more stocks were declared rebuilt in 2012, bringing the total number of stocks rebuilt since 2000 to 32. This year’s rebuilt stocks include Southern Tanner crab, Acadian redfish, windowpane, yellowtail flounder, coho salmon, and pink shrimp. ”

“In addition, overfishing is at an all-time low with 10 additional stocks removed from the overfishing list since last year.  The details behind these record-setting trends are included in NOAA Fisheries’ new 2012 Report on the Status of U.S. Fisheries which is available online.

He also noted “It is critical that we recognize the sacrifices that have been made and will be made to achieve these gains.”  So far, Congress has been very reluctant to acknowledge that the gains in fisheries sustainability have a price that has been borne almost exclusively by the seafood industry.
