SEAFOODNEWS.COM [Letters] - June 23, 2015Editor’s Note: The following letter from D.B. Pleschner was reviewed and supported by Mike Okoniewski of Pacific Seafoods.To the Editor: I take exception to your statement: "The author of this piece, Elizabeth Grossman, buys into the argument, but in a fair article.”In no way was this “fair” reporting. She selectively quotes (essentially misquotes) both Mike Okoniewski and me (and this after I spent more than an hour with her on the phone, and shared with her the statements of Ray Hilborn, assessment author Kevin Hill and other noted scientists.) She does not balance the article but rather fails to emphasize the NOAA best science in favor of the Demer-Zwolinski paper, published in NAS by NOAA scientists who did not follow protocol for internal review before submitting to NAS (which would have caught many misstatements before they saw print).NOAA’s Alec MacCall later printed a clarification (in essence a rebuttal) in NAS, which pointed out the errors and stated that the conclusions in the Demer paper were “one man’s opinion”.Oceana especially has widely touted that paper, notwithstanding the fact that the SWFSC Center Director also needed to testify before the PFMC twice, stating that the paper’s findings did not represent NOAA’s scientific thinking.After the Oceana brouhaha following the sardine fishery closure, NOAA Assistant Administrator Eileen Sobeck issued a statement. SWFSC Director Cisco Werner wrote to us in response to our request to submit Eileen’s statement to the Yale and Food & Environment Reporting Network to set the record straight:“The statement from the NMFS Assistant Administrator (Eileen Sobeck) was clear about what the agency's best science has put forward regarding the decline in the Pacific Sardine population. Namely, without continued successful recruitment, the population of any spp. will decline - irrespective of imposed management strategies.”It is also important to note that we are working closely with the SWFSC and have worked collaboratively whenever possible.I would greatly appreciate it if you would again post Sobeck’s statement to counter the inaccurate implications and misstatements in Elizabeth Grossman’s piece.Diane Pleschner-SteeleCalifornia Wet Fish Producers AssociationPS: I also informed Elizabeth Grossman when we talked that our coastal waters are now teeming with both sardines and anchovy, which the scientific surveys have been unable to document because the research ships survey offshore and the fish are inshore.Sobeck’s statement follows:Researchers, Managers, and Industry Saw This Coming: Boom-Bust Cycle Is Not a New Scenario for Pacific SardinesA Message from Eileen Sobeck, Head of NOAA FisheriesApri 23, 2015Pacific sardines have a long and storied history in the United States. These pint-size powerhouses of the ocean have been -- on and off -- one of our most abundant fisheries. They support the larger ecosystem as a food source for other marine creatures, and they support a valuable commercial fishery.When conditions are good, this small, highly productive species multiplies quickly. It can also decline sharply at other times, even in the absence of fishing. So it is known for wide swings in its population.Recently, NOAA Fisheries and the Pacific Fishery Management Council received scientific information as a part of the ongoing study and annual assessment of this species. This information showed the sardine population had continued to decline.It was not a surprise. Scientists, the Council, NOAA, and the industry were all aware of the downward trend over the past several years and have been following it carefully. Last week, the Council urged us to close the directed fishery on sardines for the 2015 fishing season. NOAA Fisheries is also closing the fishery now for the remainder of the current fishing season to ensure the quota is not exceeded.While these closures affect the fishing community, they also provide an example of our effective, dynamic fishery management process in action. Sardine fisheries management is designed around the natural variability of the species and its role in the ecosystem as forage for other species. It is driven by science and data, and catch levels are set far below levels needed to prevent overfishing.In addition, a precautionary measure is built into sardine management to stop directed fishing when the population falls below 150,000 metric tons. The 2015 stock assessment resulted in a population estimate of 97,000 metric tons, below the fishing cutoff, thereby triggering the Council action.The sardine population is presently not overfished and overfishing is not occurring. However, the continued lack of recruitment of young fish into the stock in the past few years would have decreased the population, even without fishing pressure. So, these closures were a “controlled landing”. We saw where this stock was heading several years ago and everyone was monitoring the situation closely.This decline is a part of the natural cycle in the marine environment. And if there is a new piece to this puzzle -- such as climate change -- we will continue to work closely with our partners in the scientific and management communities, the industry, and fishermen to address it.

Council Votes to Close 2015-2016 Pacific Sardine Fishery
Regarding Council action yesterday to close what’s left of the 2014-15 sardine fishery, the Council recommended that NMFS close the directed fishery in the fastest way possible, using current rule making authority. This action stopped short of declaring an emergency, which would require justification and new rule making which could take more than a month. The Council explanation was that this closure was recommended as an added layer of precaution, considering the recent sharp decline observed in the sardine biomass due to lack of recruitment in the past few years. Given the recent uptick in directed landings in both OR and CA, it is expected that the closure could be implemented in about a week.
Some NGO's cry foul over change to Calif. sardine management when it contradicts their view

SEAFOODNEWS.COM [Opinion] By D.B. Pleschner - December 16, 2014(D.B. Pleschner is executive director of the California Wetfish Producers Association.)
Recently the Pacific Fishery Management Council voted to change the sardine harvest control rule, increasing the upper limit of the sardine harvest fraction from 15 percent to 20 percent.The decision came after an exhaustive set of scientific workshops and analysis involving more than 60 people, held over the past two years to respond to a research paper that suggested that sea surface temperature (SST) measured at Scripps Pier in Southern California, which had been employed as a proxy for sardine recruitment, was no longer correlated with recruitment success.But apparently this fact was lost on environmental activists who cried foul to the media, claiming that sardines are crashing, and the management response to the crisis is to just fish harder.Claims that the council voted for a more aggressive fishing rate miss the point: nothing could be further from the truth. But the truth is complicated.We know that California’s sardine population is strongly influenced by ocean temperatures: warmer waters tend to increase sardine productivity, while colder waters tend to decrease it.“The northern sardine stock has been declining for several years due to poor recruitment, and there is concern that it will decline further in the next couple of years,” says Dr. Richard Parrish, one of the authors of the original sardine control rule. “Although no one can predict the environmental conditions that will occur in the future, the pessimistic view is that the northern stock will continue to decline and the optimistic view is that the present warm water conditions will herald increased recruitment.”“Whichever occurs first,” he adds, “the past, present and management team-recommended sardine harvest control rules were all designed to automatically regulate the exploitation rates both by reducing the quota and reducing the harvest rates as the stock declines, and by shutting down the fishery if the biomass falls below 150,000 mt.”The original sardine analysis, made in 1998, was updated by a new analysis that found offshore sea temperatures slightly better correlated with sardine productivity than the measurements made at Scripps Pier. Population simulations made with the updated information that included the population increase in recent decades show that the sardine stock is about 50 percent more productive than thought in 1998. The management team therefore recommended raising the upper bound of fishing fraction from 15 percent to 20 percent to account for the new best available science.But that doesn’t mean that the catch quota for the coming year will be raised. This is a long-term harvest control rule that simply follows better scientific modeling efforts.The new rules will determine fishing rate just as before: If the temperature is cold, the harvest will be kept low; if the population size decreases, both the harvest rate and the allowable catch will automatically decrease. In fact, the new sardine harvest rule is actually more precautionary than the original rule it is replacing. It does this by producing an average long-term population size at 75 percent of the unfished size, leaving even more fish in the water, vs. 67 percent in the original rule. The original harvest rule reduced the minimum harvest rate to 5 percent during cold periods. The present, very complicated rule, has a minimum rate of 0 percent during cold periods.What’s more, the harvest fraction will only be applied after subtracting 150,000 mt from the sardine biomass estimated in the next year’s stock assessment.Bottom line: The California sardine may be the best-managed fishery of its type in the world — the poster fish for effective ecosystem-based management.

International Efforts to Assess the Status of Pacific Sardine Stocks
Fisheries Resources Division
Scientists from the U.S. and Canada are working together to strengthen Pacific sardine stock assessments. SWFSC scientists conduct regular Pacific sardine stock assessments to determine harvest guidelines for this economically important species. In May, Canadian and NMFS scientists, together with independent experts, considered how to integrate data from Fisheries and Oceans Canada’s West Coast Vancouver Island swept-area trawl survey (WCVI) into the Pacific sardine stock assessment.
Preliminary results of the review suggest that including the Canadian survey data could strengthen and enhance the U.S. stock assessment in the future, especially as the survey evolves. Inclusion of the Canadian survey into the assessment may provide valuable insights into the northern most extension of the Pacific sardine population, the largest size classes, and the timing and extent of migration during different years. The Pacific Fishery Management Council will consider whether to incorporate the Canadian data into the U.S. stock assessment based on the independent review results. The earliest the data could be incorporated would be for the 2014 fishing season.

Sardine population growing significantly
Opinion
By DIANE PLESCHNER-STEELE
Guest Commentary
Reading the recent opinion piece on this page by Oceana, one might think that sardines should be placed on the endangered species list. But in reality, this important fishery is doing just fine thanks to existing precautions.
The Oceana commentary, "Sardine population on verge of crash," bases some of its allegations on a report by two National Marine Fisheries Service scientists. Yet Oceana fails to mention that those scientists deliberately omitted the most recent stock assessment and failed to submit their paper for internal review. That paper and its conclusions were later repudiated by the National Marine Fisheries Service.
The fact is, sardine abundance trended significantly upward in 2011 and that led to the increase in sardine harvest quota in 2012.
California's wetfish industry — named for the fish that were canned wet from the sea — is under attack by extremist groups like Oceana who claim overfishing is occurring. That allegation is false; fishermen have long recognized that a sustainable fishery was good for both people and fish.
Historically, sardines exhibited dynamic swings of a million tons up or down during the first decade of decline. We may be entering another such period, given the 30-year cycle of the stock. But the issue is scale. Sardine management policy is complicated because fishery managers now recognize these dynamics.
The sardines' visionary harvest policy sets annual quotas far lower than the maximum sustainable catch allowed in most fisheries, and subtracts 150,000 metric tons from the population estimate, allowing for forage and uncertainty. According to the 2011 sardine stock assessment, the coast-wide harvest rate including Canada and Mexico was less than 15 percent of the biomass — decidedly NOT overfishing.
This precaution has been recognized by a host of respected scientists, including the "Little Fish, Big Impact" report referenced by Oceana. Another Oceana omission is found in Appendix E of that report:
"In the California Current only 2 percent of the annual production of forage fishes (including fished and unfished stocks) is taken by fishermen and 98 percent of the production goes to the other fishes, birds and marine mammals," notes Richard Parrish, one of the most knowledgeable scientists on the west coast.
Oceana also asserts that fishermen have exceeded the squid quota. While it's true that the total biomass of squid is unknown and likely unknowable (market squid range from Baja California to Alaska), the overfishing allegation is also decidedly false.
Squid are another dynamic stock that live, spawn and die in less than a year. The squid resource is actively managed by California with many precautionary regulations, including both weekend closures and marine reserves that have closed more than 30 percent of traditional squid fishing grounds.
Scientists know the squid's abundance is driven primarily by environmental cycles like the highly productive cold-water conditions experienced in 2010-11. These boom years for squid fishing happen only once in a decade.
California's historic wetfish fisheries are the backbone of our state's fishing economy. In 2010, the wetfish complex — sardine, anchovy, mackerel, market squid — comprised more than 80 percent of the volume of all commercial fishery landings statewide, and 44 percent of dockside value.
The wetfish industry remains the lifeblood of Monterey's fishing community, representing an even higher volume and value of all commercial landings.
The city of Monterey recognizes our precautionary fishery management and supports this historic industry. The City is working alongside California wetfish leaders, reputable environmental organizations, and respected scientists to recommend forage policy guidelines for the Fish and Game Commission.
Our recommendations integrate the protections now afforded these forage stocks by both the state and federal management — and are based on best-available science, rather than innuendo, deception and politics.

Fish on Fridays: Long-Term Fishery Investments Starting to Pay Off
By Michael Conathan | Director of Oceans Policy at the Center for American Progress.
See which fish stocks were fully rebuilt in 2011.
Earlier this month, the National Oceanic and Atmospheric Administration released its annual “Status of Stocks” report to Congress outlining the overall health of our nation’s fisheries. To the relatively small cadre of fish geeks (myself included), the release of this document is a major event. It lacks the panache of the Oscar nominations, but for us it is perhaps comparable to the way the 1 percent gets all giddy for Berkshire Hathaway’s annual letter to shareholders.
NOAA’s report for 2011, similar to that of Warren Buffett’s financial powerhouse, continued its recent trend of positive returns. The topline numbers showed modest yet continued growth in the overall health of America’s fish populations. At the end of 2011, just 14 percent of fish stocks were subject to overfishing, and 21 percent were in an overfished state—down from 16 percent and 22 percent in 2010, respectively. (Recall this description of the difference between a stock that is “subject to overfishing” and one that is “overfished.”)
Yet the most impressive news to emerge from this year’s report was that six stocks have been declared fully rebuilt—more than in any other year—bringing the overall total of stocks rebuilt since 2000 to 27.
Despite these positive trends and all the feel-good stories the report has spawned (in more than 100 newspapers nationwide), correspondence in my personal inbox this week was dominated by references to a Washington Post Wonk Room blog post proclaiming boldly that it had found “The end of fish, in one chart.”
The chart in question comes from a wide-ranging World Wildlife Fund study on global biodiversity, and it displays the dramatic increase in global fishing pressure from 1950 to 2006. The blog piece goes on to reference an overpublicized doomsday scenario article published by lead author Dr. Boris Worm in 2006 in the journal Science. Worm’s study predicts the demise of global commercial fisheries by 2048. Ah, how the mass media truly loves a ticking clock.
The rest of that story, as I explained in an earlier column, is that Worm later collaborated with several other colleagues, including Dr. Ray Hilborn, on a follow-up article that Scienceran in 2009 showing a far rosier outlook on the future of the world’s fisheries—specifically that “conservation objectives can be achieved by merging diverse management actions, including catch restrictions, gear modification, and closed areas.” Sound management practices mean fishery rebuilding is possible.
And that’s precisely what we’re now seeing in domestic fisheries with the slow but steady recovery of fish populations. Our regulations are working—at least for the fish. Yet as always, we must continue to seek the balance between regulations that work for the fish and for the fishermen.
Hilborn hit this point perfectly with an op-ed he co-authored for The New York Times earlier this week with his colleague and wife, Ulrike Hilborn. Their point, similar to one I made in this series four weeks ago, is that when we as consumers eschew overfished fisheries that are in the process of rebuilding under strictly enforced science-based catch limits, we unnecessarily penalize fishermen who are acting in the best interests of the ecosystem, coastal communities, and our national economy.
Americans should not feel guilty about eating domestically produced seafood, as long as we keep strict regulations in place that reflect the best available science and that continue working toward the rebuilding goal achieved in 2011 by six different fish stocks.

California is Global Leader in Managing Forage Fish
Note: This article also appeared in the Santa Cruz Sentinel, North County Times, Salinas Californian, and online, on Saving Seafood and Science 2.0.
Written By Steve Scheiblauer
More than 150 years ago, immigrant Chinese fishermen launched sampans into the chilly waters of Monterey Bay to capture squid. The Bay also lured fishermen from Sicily and other Mediterranean countries, who brought round-haul nets to fish for sardines. This was the beginning of the largest fishery in the western hemisphere – California’s famed ‘wetfish’ industry, imprinted on our collective conscience by writers like John Steinbeck. Who doesn’t remember Cannery Row? It was the plentiful schools of fish – especially sardines that stretch from the Gulf of California to Alaska during cycles of abundance – that provided opportunity for generations of enterprising fishing families to prosper. These families helped build not only Monterey, but the ports of many other California cities, like San Diego, San Francisco and San Pedro – the fishing hub of Los Angeles. But now, this historic industry – named for the fish that were canned wet from the sea – is under attack by extremist groups who claim overfishing is occurring. That allegation is false; fishermen have long recognized that a sustainable fishery was good for both people and fish. When the sardine resource began its storied decline in the late 1940s, wetfish fishermen levied an assessment on their catch and contributed to the beginning of the California Cooperative Fisheries Investigations (CalCOFI). A cooperative effort between the National Marine Fisheries Service, Scripps Institution of Oceanography and the Department of Fish and Game, CalCOFI now is one of the preeminent research efforts worldwide. Research has since documented the dynamic fluctuations in coastal pelagic ‘wetfish’ stocks, including sardine and anchovy, which alternate their cycles of abundance - sardines favoring warm water epochs and anchovy preferring cold. Core samples from an anaerobic trench in the Southern California Bight found alternating layers of sardine and anchovy scales over a period of 1,400 years. Turns out, sardine stocks would have declined naturally even without fishing pressure. Today the wetfish industry maintains its commitment to research with cooperative efforts ongoing for both sardine and squid. Even though the canneries are gone due to their inability to compete on a now global marketing stage, our wetfish industry is still the backbone of California’s fishing economy – responsible for more than 80 percent of the volume and more than 40 percent of dockside value in 2010. Fast forward to earlier this month, when an in-depth study by a panel of 13 hand-picked scientists provided recommendations on policies to protect forage fish – like anchovy, sardines and market squid – that larger species feed on. The study by the Lenfest Forage Fish Task Force concluded that overfishing of forage species is unfortunately occurring on a global scale. But interestingly, these scientists also identified the west coast, as different, noting that California is, “ahead of other parts of the world in how it manages some forage fish.” The region has “stricter monitoring and more conservative limits that could serve as a buffer against future crashes.” The Lenfest Report provides a strong case that forage fish are managed better in California and the Northern California Current than anywhere else in the world. Overall, forage fisheries here account for less than two percent of total forage production (including both fished and unfished stocks), leaving 98 percent for other marine life. Knowledgeable people understand that this is no accident. Fishing families have worked and are working with regulators to conserve California’s fisheries and coastal waters. In fact, after a 20-year moratorium on sardine fishing, California adopted strict fishing regulations when the sardine resource rebounded. The federal government assumed management of coastal pelagic species in 1999 and approved a visionary management strategy for the west coast ‘forage’ fish harvest, maintaining at least 75 percent of the fish in the ocean to ensure a resilient core biomass. The sardine protection rate is even higher at about 90 percent. Even so, some environmental groups are calling for deep and unnecessary cutbacks in sardine fishing in California, as well as substantial harvest reductions in other forage fish fisheries, including herring, anchovies and squid. Touting studies with faulty calculations, activists are lobbying federal regulators to massively limit fishing, if not ban these fisheries outright. Apparently the facts don’t matter to groups with an anti-fishing agenda. Their rhetoric leaves those not familiar with the fishing industry with the impression that overfishing is a huge problem in California. We hope decision makers will see through the rhetoric when developing harvest policy for California’s historic, and still important, wetfish fisheries.
