To his detractors, fisheries professor Ray Hilborn is an “overfishing denier,” a scientist who’s all too eager to accept money from industry groups to pay for his pro-fishing research.

To his backers, he’s a hero, a respected researcher who can always be counted on to challenge environmental groups that want to limit fishing.

Love him or hate him, there’s little doubt that the outspoken Hilborn has attained an international profile and that he has found a way to win big-time attention in fishing circles.

His next stop is Capitol Hill.

Tomorrow, Hilborn, a professor of aquatic and fishery sciences at the University of Washington, will appear before a Senate Commerce, Science and Transportation panel, getting another chance to argue his case that overfishing is no longer a concern for the United States.

He’s one of four experts scheduled to testify before the Subcommittee on Oceans, Atmosphere, Fisheries and Coast Guard.

“What I’m going to say in my testimony is that overfishing is no longer the major threat to the sustainability of our oceans or biodiversity,” Hilborn said in an interview. “My first line on Tuesday is going to be that we have really fixed our fisheries by having fisheries management follow science advice — and if you stop doing that, you’re in trouble.”

Hilborn also said it’s time to stop “vilifying” fishing.

“I wrote the book on overfishing, called ‘Overfishing: What Everyone Needs to Know,’ by Oxford University Press,” Hilborn said. “You know, overfishing is a serious problem in many places. It’s not a very serious problem in the United States now. It was 30 years ago. … And the U.S. has responded, as has Europe. In most developed countries, fish stocks are increasing in abundance, they are not declining in abundance.”

The question of overfishing is a key focus for Congress as lawmakers consider making changes to the Magnuson-Stevens Fishery Conservation and Management Act, a law passed in 1976 that sets the rules for fishing in federal waters (E&E Daily, July 17).

Backers and opponents alike credit the landmark law for improving the health of U.S. fish stocks, though many worry the Trump administration has moved too quickly to allow more fishing.

Commerce Secretary Wilbur Ross, who oversees NOAA, heightened those concerns with two key decisions: In June, he extended the season for the Gulf red snapper by 39 days, and in July, he overturned a decision by the Atlantic States Marine Fisheries Commission that would have cut New Jersey’s recreational quota for summer flounder, also known as fluke (Greenwire, Sept. 20).

Critics fear Ross’ decisions could lead to overfishing and jeopardize both fish stocks in the long run.

Meanwhile, the president’s fisheries chief, Chris Oliver, told a House Natural Resources panel last month that 91 percent of all fishing stocks assessed by NOAA are no longer subject to overfishing.

Oliver, the head of NOAA Fisheries, told the Subcommittee on Water, Power and Oceans that the U.S. had “effectively ended overfishing,” allowing “room for flexibility” in applying annual catch limits (E&E Daily, Sept. 27).

Those are fighting words for many conservationists who worry the Trump team has already gone overboard in bowing to the demands of fishing groups.

“When they talk about flexibility, they’re really talking about rollbacks,” said John Hocevar, a marine biologist and ocean campaigns director for Greenpeace USA.
An ideal spokesman?

Hilborn has plenty of fans, but he has faced accusations of industry bias.

Last year, he won the International Fisheries Science Prize at the World Fisheries Congress in Busan, South Korea, recognized for a 40-year-career of “highly diversified research” on behalf of global fisheries science and conservation.

“There aren’t many fisheries scientists in the country who can match Ray Hilborn,” said Noah Oppenheim, executive director of the Pacific Coast Federation of Fishermen’s Associations. “He’s the ideal spokesman for his field to educate Congress about how science informs fisheries management. Anyone who questions Ray’s professional or scientific integrity doesn’t understand how science works, at best.”

But a study by Greenpeace last year found that Hilborn accepted more than $3.55 million from 69 commercial fishing and seafood interests to pay for his research from 2003 to 2015.

“It seems like he uses his genuine scientific credentials to make himself more valuable to industry as a spokesperson,” said Hocevar. “On climate denial, there are a bunch of those guys. But with fisheries, Hilborn is the guy. … He’s the go-to, and there’s really no one else out there like him who will come out and talk about how we don’t need marine protected areas and how the real problem is underfishing, not overfishing.”

Greenpeace gained access to University of Washington documents that showed Hilborn’s long and extensive links to fishing, seafood and other corporate groups by filing a request under the state’s public records law.

After Greenpeace complained that Hilborn had not properly disclosed his affiliations in all his published papers, the university investigated the issue and concluded Hilborn had not violated any of its policies.

But Hocevar said the issue is still relevant.

“He took millions of dollars from industry. … And studies have shown that where you get your funding from does create bias in terms of findings,” Hocevar said.

Hilborn dismissed the criticism from Greenpeace.

“You know, they’re hopeless fundamentally,” he said. “They’re basically a money-raising organization, and they have to scare people to raise money. They’re not interested in science at all. … Greenpeace has sort of put its cards on the table that fishing is a big deal, and they’re not going to raise money if people don’t believe that fishing is a threat.”

Schedule: The hearing is Tuesday, Oct. 24, at 2:30 p.m. in 253 Russell.

Witnesses: Karl Haflinger, founder and president, Sea State Inc.; Ray Hilborn, professor, University of Washington School of Aquatic and Fishery Sciences; Michael Jones, professor, Michigan State University Quantitative Fisheries Center; and Larry McKinney, director, Texas A&M University Harte Research Institute for Gulf of Mexico Studies.

Fishing Not to Blame for Sea Lion Deaths

Complex, proactive management efforts have been in place for decades to prevent overfishing in California, efforts are working.

Buellton, California (PRWEB) February 01, 2016

Recent media accounts report how sea lion pups are stranding on shore and dying in record numbers because there aren’t enough sardines and anchovies – sea lions’ favorite food – to support their growing population. For example, the Orange County Register, even after acknowledging the cyclical nature of the ocean and marine species, points to overfishing as the problem. (see story here).

“While it seems all too common these days to blame the ocean’s woes on overfishing, the truth is far different in California. Fortunately, we do have an accurate picture. It’s a graph that shows natural sardine booms and busts for the past 1,400 years,” said Diane Pleschner-Steele, executive director for the California Wetfish Producers Association. “Oceanic core samples were extracted from an anaerobic trench in the Santa Barbara Channel and study findings were reported by Dr. Tim Baumgartner and others in a 1992 California Cooperative Fisheries Investigations (CalCOFI) report. The study correlated alternating periods of sardine and anchovy population recruitments and collapses related to warm and cold water oceanic cycles. Sardines tend to favor warm water cycles while anchovy favor cold.

“It’s important to note that most collapses in this timeframe occurred when there was virtually no commercial fishing. The great fluctuations experienced by sardines and anchovies have been known for a long time to be part of a natural cycle,” said Pleschner-Steele.

Fishery scientists can confirm that the recent sardine decline was not the result of overfishing. The less than 8,000 tons of sardine harvested in California in 2014 were still below the federally mandated overfishing limit.

When sardines began returning to abundance in the 1980s, they became perhaps the best-managed fishery in the world – the poster fish for effective ecosystem-based management. The current harvest control rule – established 17 years ago and updated in 2014 with more precautionary science – sets a strict harvest guideline every year that considers ocean conditions and automatically reduces the catch limit as the biomass declines.

Since federal management began in 2000, the sardine biomass estimate has declined more than 70 percent from the 2006 high of 1.3 million mt, and harvest limits have fallen from 152,564 mt in 2007 to a U.S. catch target of 23,293 mt in 2014 – an 85 percent decline. In 2015, the estimated sardine biomass fell below the established “cutoff,” the biomass level above which sardine fishing is allowed, and the directed fishery was closed. This is a perfect example of our fishery management at work to prevent overfishing.

Compare this to the 1940s and ’50s when the fishery harvest averaged 43 percent or more of the standing sardine stock with little regulatory oversight and no limit on the annual catch. The historic sardine fishery collapse devastated Monterey’s Cannery Row.

But that was nearly 70 years ago. The current sardine fishery harvest is less than a quarter of the rate observed during the historical sardine collapse. The current harvest regulations leave close to 90 percent of sardines in the ocean as forage for marine life.

As for anchovy, harvests have actually averaged less than 8,000 tons annually over the last 14 years. Reports often cite a new study alleging a recent anchovy “collapse,” but the study period stopped in 2011 and excluded nearshore egg and larval data where young anchovies always live and spawn. In fact, field surveys in 2015 recorded recruitment of sardine and anchovy larvae and juveniles as “the highest ever” in Central California and relatively high in Southern California. Fishermen in both Monterey and Southern California attest to the abundance of anchovy and sardine along the coast.

“Complex, proactive management efforts have been in place for decades to prevent overfishing in California, efforts are working,” said Pleschner-Steele.

CFOOD: DO “CATCH RECONSTRUCTIONS” REALLY IMPLICATE OVERFISHING?

January 22, 2016—The following is commentary from Michel J. Kaiser of Bangor University and David Agnew of the Marine Stewardship Council concerning the recently published article, “Catch Reconstructions Reveal that Global Marine Fisheries Catches are Higher than Reported and Declining” by Daniel Pauly and Dirk Zeller in Nature.

A new paper led by Daniel Pauly of the University of British Columbia that found global catch data, as reported to the FAO, to be significantly lower than the true catch numbers. “Global fish catches are falling three times faster than official UN figures suggest, according to a landmark new study, with overfishing to blame.”

400 researches spent the last decade accumulating missing global catch data from small-scale fisheries, sport fisheries, illegal fishing activity and fish discarded at sea, which FAO statistics, “rarely include.”

“Our results indicate that the decline is very strong and is not due to countries fishing less. It is due to countries having fished too much and having exhausted one fishery after another,” Pauly says.

Despite these findings, Pauly doesn’t expect countries to realize the need to rebuild stocks, primarily because the pressures to continue current fishing effort are too strong in the developing world. But this study will allow researchers to see the true problems more clearly and hopefully inform policy makers accordingly.

Comment by Michel J. Kaiser, Bangor University, @MicheljKaiser

Catch and stock status are two distinct measurement tools for evaluating a fishery, and suggesting inconsistent catch data is a definitive gauge of fishery health is an unreasonable indictment of the stock assessment process. Pauly and Zeller surmise that declining catches since 1996 could be a sign of fishery collapse. While they do acknowledge management changes as another possible factor, the context is misleading and important management efforts are not represented. The moratorium on cod landings is a good example – zero cod landings in the Northwest Atlantic does not mean there are zero cod in the water. Such distinctions are not apparent in the analysis.

Another key consideration missing from this paper is varying management capacity. European fisheries are managed more effectively and provide more complete data than Indian Ocean fisheries, for example. A study that aggregates global landings data is suspect because indeed landings data from loosely managed fisheries are suspect.

Finally the author’s estimated catch seems to mirror that of the official FAO catch data, ironically proving its legitimacy. “Official” FAO data is not considered to be completely accurate, but rather a proportionate depiction of global trends. Pauly’s trend line is almost identical, just shifted up the y axis, and thus fails to significantly alter our perception of global fisheries.

Comment by David Agnew, Director of Standards, Marine Stewardship Council

The analysis of such a massive amount of data is a monumental task, and I suspect that the broad conclusions are correct. However, as is usual with these sorts of analyses, when one gets to a level of detail where the actual assumptions can be examined, in an area in which one is knowledgeable, it is difficult to follow all the arguments.  The Antarctic catches “reconstruction” apparently is based on one Fisheries Centre report (2015 Volume 23 Number 1) and a paper on fishing down ecosystems (Polar Record; Ainley and Pauly 2014). The only “reconstruction” appears to be the addition of IUU and discard data, all of which are scrupulously reported by CCAMLR anyway, so they are not unknown. But there is an apparent 100,000 t “unreported” catch in the reconstruction in Figure 3, Atlantic, Antarctic (48). This cannot include the Falklands (part of the Fisheries Centre paper) and it is of a size that could only be an alleged misreporting of krill catch in 2009. This is perhaps an oblique reference to concerns that CCAMLR has had in the past about conversion factors applied to krill products, or perhaps unseen (net-impact) mortality, but neither of these elements have been substantiated, nor referenced in the supporting documentation that I have seen (although I could not access the polar record paper).

The paper does not go into much detail on these reasons for the observed declines in catches and discards, except to attribute it to both reductions in fishing mortality attendant on management action to reduce mortality and generate sustainability, and some reference to declines in areas that are not managed. It is noteworthy that the peak of the industrial catches – in the late 1990s/early 2000s – coincidentally aligns with the start of the recovery of many well managed stocks. This point of recovery has been documented previously (Costello et al 2012; Rosenberg et al 2006; Gutierrez et al 2012) and particularly relates to the recovery of large numbers of stocks in the north Pacific, the north Atlantic and around Australia and New Zealand, and mostly to stocks that are assessed by analytical models. For stocks that need to begin recovery plans to achieve sustainability, this most often entails an overall reduction in fishing effort, which would be reflected in the reductions in catches seen here. So, one could attribute some of the decline in industrial catch in these regions to a correct management response to rebuild stocks to a sustainable status, although I have not directly analyzed the evidence for this. This is therefore a positive outcome worth reporting.

The above-reported inflection point is also coincident with the launch of the MSC’s sustainability standard. These standards have now been used to assess almost 300 fisheries, and have generated environmental improvements in most of them (MSC 2015). Stock sustainability is part of the requirements of the standard, and previous analyses (Gutierrez et al 2012, Agnew et al 2012) have shown that certified fisheries have improved their stock status and achieved sustainability at a higher rate than uncertified fisheries. The MSC program does not claim responsibility for the turn-around in global stocks, but along with other actions – such as those taken by global bodies such as FAO, by national administrations, and by industry and non-Governmental Organisations – it can claim to have provided a significant incentive for fisheries to become, and then remain, certified.

Hilborn Says Newsweek Article “May Set a New Record for Factual Errors”

— Posted with permission of SEAFOODNEWS.COM. Please do not republish without their permission. —

Copyright © 2015 Seafoodnews.com

November 3, 2015

Dr. Ray Hilborn, Professor in the School of Aquatic and Fishery Sciences at the University of Washington, takes issue with Newsweek’s August 9, 2015 article “Our Taste for ‘Aquatic Bushmeat’ Is Killing the Sea” and its bleak picture of the state of worldwide seafood.

The article quotes Dr. Sylvia Earle, a former chief scientist at NOAA and now a National Geographic explorer-in-residence.

The article incorrectly claimed that 90 percent of global stocks had been removed in the last half-century and that 90 percent of the worlds stocks were unsustainably harvested. The latter statement was corrected to 29 percent after CFOOD staff pointed out the error.

CFOOD is a coalition of fisheries scientists from around the world who are correcting inaccuracies about stock abundance, management measures, and global ocean status. They back up their corrections with scientific data. Their website cfooduw.org lists myths “that won’t go away” and corrects them. For example, there are summaries of global stock assessments that show that stocks will not collapse by 2048, 70 percent of the world’s fish are not overfished, and we are not fishing down the food chain, among others.

Newsweek writer Douglas Main referred to a 2003 report that estimated large fish populations (three species of tuna) had crashed worldwide based primarily on catch per unit of effort, now considered a biased metric to gauge abundance.

The 2003 report was repeatedly refuted in subsequent scientific papers. By 2011, a correct estimate of 28.8 percent of fish stocks were considered fished at a biologically unsustainable level.

“The graph below shows the trend in the number of stocks overfished according to the Food and Agriculture Organization of the United Nations,” wrote Hilborn. It shows that after rising steeply between 1970 and 1990, the rate of increase in overfishing rapidly declined, and total overfishing is now stands at 28.8% of global stocks.

Hilborn pointed out that Newsweek’s article repeated the often rebutted statement that 90 percent of the large fish of the ocean were gone by 1980.

“Yet again the author and Dr. Earle don’t seem to have read the scientific literature or have conducted any due diligence with respect to the facts in the article. Certainly those stocks declined from 1950 to 2005 but they were mostly not overfished and the declines were a natural part of newly developing fisheries,” says Hilborn.

“In fact, in many places of the world overfishing is disappearing and stocks are increasing. Cod in most of the North Atlantic are coming back, and Atlantic bluefin tuna is increasing rapidly.

“The idea that on the whole global fisheries are not sustainably managed is out and out wrong,” Hillborn wrote. “In many places such as North America, Australia, New Zealand, Iceland, and Norway fisheries are sustainably managed.”

Overfishing that has occurred is now declining in many countries including the European Union members, Chile, Peru, South African, Japan and Argentina.

“Certainly there are many fisheries in the world that need better management, but we must understand where and why some stocks are overfished and this requires good science,” Hilborn said.

Earle admonished people who don’t think about what kind of fish they eat or where it is from. “This kind of traceability is hard to achieve,” Hilborn points out, especially in areas where regulations are lax and fishing is strong, such as parts of Asia and Africa.

“Dr. Earle is an advocate for minimizing human impacts on the ocean but and has frequently argued that we should not fish at all. This is despite the fact that fish provide essential nutrition and employment for many of the world’s poorest people.

“The challenge is to assure that all of the worlds fisheries are sustainable and totally incorrect statements are no help in achieving this goal,” Hilborn said.

Researchers Keep Missing Picture on Sardines, Where there is a 1400 Year History of Boom and Bust

— Posted with permission of SEAFOODNEWS.COM. Please do not republish without their permission. —

Copyright © 2015 Seafoodnews.com

“Climate variations or natural boom-and-bust cycles contribute to population fluctuation in small fast-growing fish, ” Pinsky said, “but when they are not overfished, our data showed that their populations didn’t have any more tendency to collapse than other fish. ” He called these findings counterintuitive because the opposite dynamic holds true on land: “Mice thrive while lions, tigers and elephants are endangered, ” he said.

While it’s common these days to blame the ocean’s woes on overfishing, the truth is Pinsky’s conclusions don’t paint a complete picture. Fortunately, we do have an accurate picture and it’s definitely better than the proverbial thousand words.

The picture is a graph (adapted from Baumgartner et al in CalCOFI Reports 1992, attached) that shows sardine booms and busts for the past 1,400 years. The data were extracted from an anaerobic trench in the Santa Barbara Channel which correlated sardine and anchovy recoveries and collapses with oceanic cycles.

It’s important to note that most of sardine collapses in this timeframe occurred when there was virtually no commercial fishing. The best science now attributes great fluctuations and collapses experienced by sardines to be part of a natural cycle.

“Pinsky has never been a terrestrial biologist or naturalist or he would have known that small rodents have boom and bust cycles brought about by combinations of environmental conditions and the mice’s early maturity and high fecundity rates, ” says Dr. Richard Parrish, an expert in population dynamics now retired from the National Marine Fisheries Service, .

“All fish stocks show boom and bust cycles in recruitment unrelated to fishing, ” says Dr. Ray Hilborn, internationally respected fisheries scientist from the University of Washington. “Sardines in particular have been shown to have very great fluctuations and collapses long before commercial fishing. Fast growing, short-lived species will be much more likely to decline to a level called “collapse” when recruitment fluctuates because they are short lived — longer lived species won’t decline as much. ”

As a further poke in the eye to the truth, Pinsky cites sardines off the coast of Southern California as a species that has seen fluctuations for thousands of years, but “not at the levels that they’ve experienced in recent decades due to overfishing. ”

Again, this simply is not true.

Since the fishery reopened in 1987, Pacific sardines have been perhaps the best-managed fishery in the world – the poster fish for effective ecosystem-based management. The current harvest control rule, updated to be even more precautionary in 2014, sets a strict harvest guideline that considers ocean conditions and automatically reduces the catch limit as the biomass declines.

If the temperature is cold – which scientists believe hampers sardine recruitment – the harvest is reduced. And if the population size declines, both the harvest rate and the allowable catch will automatically decrease, and directed fishing will be stopped entirely when biomass declines below 150,000 mt.

In fact, the current sardine harvest rule is actually more precautionary than the original rule it replaced. 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 has a minimum rate of 0 percent during cold periods.

Compare this to the 1940s and ’50s when the fishery harvest averaged 43 percent or more of the standing sardine stock with little regulatory oversight and no limit on the annual catch. This, coupled with unfavorable ocean conditions, culminated in the historic sardine fishery collapse that devastated Monterey’s Cannery Row.

But that was nearly 70 years ago, not “recent decades. ” Our current fishery harvest is less than a quarter of the rate observed during that historical sardine collapse.

As a scientist, Pinsky should be aware of the complex, proactive management efforts that have been in place for decades to prevent overfishing in California and the west coast. He should also be aware of the data from Baumgartner that contradicts his faulty conclusions.

Ray Hilborn: Analysis Shows California Sardine Decline Not Caused by Too High Harvest Rate

Posted with permission from SEAFOODNEWS — Please do not repost without permission.

SEAFOODNEWS.COM [SeafoodNews]  (Commentary) by  Ray Hilborn April 22, 2015

Two items in the last weeks fisheries news have again caused a lot of media and NGO interest forage fish. First was publication in the Proceedings of the National Academy of Sciences of a paper entitled “Fishing amplifies forage fish population collapses” and the second was the closure of the fishery for California sardine.  Oceana in particular argued that overfishing is part of the cause of the sardine decline and the take home message from the PNAS paper seems to support this because it showed that in the years preceding a “collapse” fishing pressure was unusually high.

However what the PNAS paper failed to highlight was the real cause of forage fish declines.  Forage fish abundance is driven primarily by the birth and survival of juvenile fish producing what is called “recruitment”.  Forage fish declines are almost always caused by declines in recruitment,  declines that often happen when stocks are large and fishing pressure low.  The typical scenario for a stock collapse is (1) recruitment declines at a time of high abundance, (2) abundance then begins to decline as fewer young fish enters the population, (3)  the catch declines more slowly than abundance so the harvest rate increases, and then (4) the population reaches a critical level that was called “collapsed” in the PNAS paper.

Looking back at the years preceding collapse it appears that the collapse was caused by high fishing pressure, when in reality it was caused by a natural decline in recruitment that occurred several years earlier and was not caused by fishing.

The decline of California sardines did not follow this pattern, because the harvest control rule has reduced harvest as the stock declined,  and as fisheries management practices have improved this is now standard practice.  The average harvest rate for California sardines has only been 10% per year for the last 10 years, compared to a natural mortality rate of over 30% per year.  Even if there had been no fishing the decline in California sardine would have been almost exactly the same.

In many historical forage fish declines fishing pressure was much higher, often well over 50% of the population was taken each year and as the PNAS paper highlighted, this kind of fishing pressure does amplify the decline.  However many fisheries agencies have learned from this experience and not only keep fishing pressure much lower than in the past, but reduce it more rapidly when recruitment declines.

So the lesson from the most recent decline of California sardine is we have to adapt to the natural fluctuations that nature provides.  Yes, sea lions and birds will suffer when their food declines, but this has been happening for thousands of years long before industrial fishing.  With good fisheries management as is now practiced in the U.S. and elsewhere forage fish declines will not be caused by fishing.

At Asia-Pacific summit, Kerry gives wrong advice for world’s fisheries

Environmental sustainability was one of the top concerns at the mid-November Asia-Pacific Economic Cooperation (APEC) summit in Beijing, as shown by the potentially groundbreaking climate agreement reached between the United States and China. The fate of the world’s oceans, from issues ranging from climate change to overfishing, was also in the spotlight, being mentioned by Secretary of State John Kerry as one of many challenges facing the Asia-Pacific region. Unfortunately, the solutions we’re focusing on are not enough to solve the problems that our marine environments face.

The APEC summit is the most recent instance in which the US has touted the expansion of marine preserves as a tonic for global overfishing, especially as climate change and ocean acidification threaten to radically alter our ocean ecosystems. This past September, the Administration created the largest marine reserve in the world when it expanded the Pacific Remote Islands Marine National Monument, moving this strategy to the forefront of our international ocean policy. Secretary Kerry hailed this development as “critical” at the summit, going on to note, “most of the fisheries of the world are overfished.”

But Secretary Kerry gets some key facts wrong here. For one, most of the fisheries of the world are not overfished. In 2014, the UN Food and Agriculture Organization (FAO) placed that number at 29 percent, and reported that approximately 70 percent of the stocks that they assessed were being fished within biologically sustainable levels. If the U.S. is going to promote sustainability worldwide, it should acknowledge current management successes.

And more importantly, these Marine Protected Areas (MPAs) aren’t sufficient to solve some of the most pressing issues affecting our oceans, despite our nation’s recent enthusiasm for promoting them.

MPAs are certainly very useful for certain conservation goals. They can protect vulnerable habitats like coral reefs as well as benefit some species of fish that make those habitats their home. But their widespread adoption presents several challenges and raises several concerns. The biggest issue is that—especially in the developing world—people still need to fish. It’s a valuable source of employment, and an even more valuable source of protein. The FAO estimated that in 2011, 2.3 billion people relied on fish as a significant source of animal protein. A shift from seafood to other, land-based food sources like meat and agriculture may actually increase greenhouse emissions and pollution, making these threats to our oceans even worse.

MPAs are also a much more limited tool than currently acknowledged. They do little to help certain stocks of highly migratory fish, like tuna, which don’t remain in any closed area long enough to reap much of the benefits. Even stocks that stay in one place might not benefit for long. With climate change putting increasing pressure on stocks to migrate from their traditional territories to cooler waters, the spatial limitations of an MPA are a poor fit for the habitat changes that are likely to occur. Similarly, MPAs provide little protection against the increasingly prominent effects of ocean acidification. Effectively dealing with these growing climate problems is going to require a long-term strategy that is simply outside the reach of fisheries management.

Fishing isn’t likely to go away anytime soon, and a global conservation strategy that’s too reliant on keeping fishermen out of an ever-expanding set of ocean reserves has some obvious political, economic, and practical limits. Adopting more sustainable management measures for some of the world’s largest fisheries, many of them in APEC member countries, would likely have a much greater impact.

So what’s the best way to address the problem of overfishing and prepare for climate change? We need to promote a combination of strategies at the international level that have worked so well in some of the world’s best managed fisheries, such as New Zealand, Norway, Iceland, and here in the United States. When effectively implemented, measures like limiting the size of fish that can be caught, controlling how much fish is caught, and restricting the ways in which fish can be caught all produce effects similar to those seen in successful MPAs. They also have the benefit of sustaining fishing economies and maintaining fish as a viable source of food.

No conservation measures, whether on climate, or pollution, or overfishing, can be sustainable in the long-term unless they confront economic and political realities. Promoting better fishing, rather than simply displacing or banning it all together, is far more likely to win support among the developing world, which can’t afford to sacrifice a critical way of life.

D.B. Pleschner: California’s ports, fishermen rely on healthy wetfish fisheries

Despite gloomy predictions of El Niño and the broader impact of climate change on the ocean and planet, California’s historic wetfish fisheries carry on — still the foundation of California’s fishing economy.

More than 150 years ago, Chinese fishermen rowed Monterey Bay at night in sampans, with baskets of burning fat pine on the bow used as torches to attract market squid, which fishermen harvested with round-haul nets.

This was the modest beginning of California’s “wetfish” industry. The immigrant Asian, Italian, Slavic and other nationalities of fishermen who came to America introduced new fishing methods. Around the turn of the 20th century, Sicilian immigrants to Monterey brought their lampara nets, another type of round-haul net, and launched what would become the largest fishery in the western hemisphere — California’s famed sardine industry, popularized in our collective conscience by John Steinbeck’s “Cannery Row.”

It was the plentiful schools of fish — especially sardines that stretch from the Gulf of California to Alaska — that provided opportunity for generations of enterprising fishing families to prosper. The complex of fisheries that makes up California’s wetfish industry, including mackerel and anchovy as well as squid and sardines, helped to build the ports of Monterey and San Pedro, as well as San Diego and San Francisco. Wetfish, now called coastal pelagic species (CPS), have contributed the lion’s share of California’s commercial catch since before the turn of the 20th century.

Even back then fishermen recognized that a sustainable fishery was good for both fisherman and fish. That’s why over the decades fishing interests have supported marine protections based on sound science and have contributed significantly to cooperative research. That tradition continues today.

In fact, today coastal pelagic fisheries in California like squid and sardines are managed with strict quotas as well as numerous time and area closures, including a statewide network of no-take marine reserves. Fishermen are allowed to harvest only a small percentage of the overall fish population. Current regulations require that at least 75 percent of CPS finfish must stay in the ocean to ensure a resilient core biomass, and the sardine protection rate is even higher at about 90 percent.

In addition, squid fishing is closed on weekends (squid live less than a year and die after spawning). And about 30 percent of squid spawning grounds are also closed in reserves.

What’s more, to preserve the quality of the catch, fishermen typically fish day trips near the ports. This makes California’s CPS fisheries among the most efficient and “greenest” fisheries on the planet with one of the lowest carbon footprints in the world. For example, wetfish fisheries can produce 2,000 pounds of protein for only six gallons of diesel fuel. This highlights the importance of California wetfish to California.

Beyond history, culture and sustainability, California’s CPS fisheries contribute essential revenue into local port communities. Wetfish fisheries are an important part of California’s fishing economy and squid is California’s most valuable fishery. Statewide, these fisheries represent more than 80 percent of all landings and close to 40 percent of dockside value of all fisheries in the Golden State!
