Squid fishing debuts on North Coast

timesstandardlogoPosted:  09/11/2014 11:21 PM

Squid fishing boats docked in Eureka for the first time Thursday, unloading 124,000 pounds of squid at the Fisherman’s Terminal.

Commercial squid fishermen from Southern California were drawn to the North Coast by following squid that were driven out of their typical habitat by a rise in ocean water temperatures, said Jeff Huffman, Eureka dock manager with Wild Planet, who helped to facilitate the docking and unloading of the squid boats.

With few squid left in their typical fishing zones this year, Southern California Sea Food, Inc., has been moving up the coast. On Wednesday, two boats fished in the area between the mouth of the Mad River and the False Cape, south of the Eel River, bringing the first boat into the dock at 2 a.m. Thursday and the second at 7:30 a.m., Huffman said.

“The squid fishery has always been a Southern California fishery, but because of the  warm water down south the squid are all up here,” he said. “There have always been some squid here, but not in these numbers.”

Unusual patterns in the Pacific Ocean have shifted water temperatures, creating unusually warm water both to the north and south of California’s North Coast, said Eric Bjorkstedt, research fishery biologist with NOAA’s Southwest Fisheries Science Center and an adjunct professor in Humboldt State University’s fisheries biology department.

The temperatures have not grown warmer off the Northern California coast, which appears on National Oceanic and Atmospheric Administration maps that track water temperatures as one of the only places along the West Coast that does not appear dark red — the color that indicates warming waters.

While this is not a typical El Nino year, Bjorkstedt said some patterns are consistent with the weather phenomena’s conditions.

“Normally in an El Nino, market squid do very badly — usually the catches go nearly to zero,” he said. “The reproductive success is not high, and the squid industry basically crashes for that year.”

Squid populations could be shifting north because of a change in water temperatures or shifting closer to shore because they are following a shift in nutrients and food supply, said Jeffrey Abell, chairman of HSU’s oceanography department.

Shifts in weather patterns and climate causes water temperatures and ocean nutrients patterns to change, he said.

“It manifests the shifts in ocean circulation, which alters the input of nutrients into the ecosystem, and then the organism responds to that and moves into a range where it is not usually found,” Abell said.

Either way, there is an unprecedented number of squid off the North Coast, Huffman said.

Southern California Sea Food, Inc., hopes to bring in 300 tons of squid every 24 hours, and the squid is then transported in trucks to Monterey, where it is processed at a company plant, he said.

Huffman added the company is limited by the number of squid that they can process, unload and truck, but not by the amount of squid in the bay.

“I think they can definitely catch more than we can actually get through the place and shipped out,” he said.

By Sunday the company will have five boats in the area, and they are hoping to continuing fishing here for two to three weeks, Huffman said.

Having the fishermen in town will be a boost for the local economy, he said, as the crew of more than a dozen people stays in local hotels, eats, shops, buys fuel and pays for moorings at the marina.

“This is a great plus to the whole waterfront and the town,” Huffman said.

The goal of the Fisherman’s Terminal was to bring in this type of business, he said. The dock is typically used for processing crab, salmon and some other fish, but being able to unload squid there adds another avenue for profit.

“It is a unique opportunity for the city to use its loading dock. Normally this isn’t something that we get to do,” said Eureka Councilwoman Marian Brady.

“It is all money that is coming back into our economy,” she said. “We definitely need industry, and this is a form of commerce that uses our bay for its purpose. We built all this infrastructure, and it hasn’t been used optimally.”

The city is working on plans to get a cold storage facility in town to keep even more of the business local, she said. All the squid is currently being taken out of town to be processed.

“But these three to five ships that are in here, that is adding a spurt to our economy,” she said.

This is a positive development for the economy and the city, said Ken Bates of the Humboldt Fishermen’s Marketing Association.

“This activity at Fisherman’s Terminal is exactly the kind of thing we were hoping to see in Eureka when this facility was built,” he said. “It’s exciting.”

Eating fish could lower your risk of hearing loss: study

plate

All it takes is two or more servings per week, and it doesn’t matter what kind you consume. The omega-3 fats in fish help preserve hearing, it seems.

AFP RELAXNEWS | Thursday, September 11, 2014, 12:46 PM
ElenaGaak /shutterstock.com According to recent research, two or more servings of fish per week could reduce women’s chances of hearing loss by as much as 20%.

According to researchers at Brigham and Women’s Hospital in Boston, two or more servings of fish per week could lower women’s risk of acquired hearing loss.

“Consumption of any type of fish (tuna, dark fish, light fish, or shellfish) tended to be associated with lower risk,” says corresponding author Dr. Sharon G. Curhan, MD, of BWH Channing Division of Network Medicine. “These findings suggest that diet may be important in the prevention of acquired hearing loss.”

In the massive cohort study, researchers tracked a total 65,215 women from 1991 to 2009.

Overall, participants self-reported 11,606 cases of incident hearing loss, and data analysis indicates that the women who consumed fish at least twice per week showed a 20% lower risk of hearing loss than the women who seldom ate fish.

Case-by-case observation revealed that higher consumption of each of the aforementioned fish types and increased intake of long-chain omega-3 polyunsaturated fatty acids (PUFA) in the women’s diets showed benefits for hearing preservation.

“Acquired hearing loss is a highly prevalent and often disabling chronic health condition,” says Dr. Curhan. “Although a decline in hearing is often considered an inevitable aspect of aging, the identification of several potentially modifiable risk factors has provided new insight into possibilities for prevention or delay of acquired hearing loss.”

The study was published in the journal American Journal of Clinical Nutrition.

UN warns on ocean acidification as GHG levels soar

Carbon dioxide emissions in 2013 were largest on record since 1984, says World Meteorological Organization 

Shellfish are vulnerable to acidification, as acid in waters prevents species developing calcium shells  (Pic: NOAA)

By Ed King

Current levels of ocean acidification are “unprecedented” and directly linked to rising emissions of carbon dioxide, according to the UN’s World Meteorological Organization (WMO). 

In a greenhouse gas analysis of 2013, released on Tuesday, it said concentrations of CO2 in the air had risen more than any other year since 1984. Methane and nitrous oxide levels also rose.

Carbon dioxide levels in the atmosphere are now 142% higher than 1750, before the industrial revolution.

And the WMO said data showed the warming effect on the world’s climate due to greenhouse gases, known as radiative forcing, had risen 34% between 1990 and 2013.

“Carbon dioxide remains in the atmosphere for many hundreds of years and in the ocean for even longer,” said WMO secretary general Michel Jarraud.

“Past, present and future CO2 emissions will have a cumulative impact on both global warming and ocean acidification. The laws of physics are non-negotiable.”

Jarraud added the latest data should be used as a “scientific base for decision-making”.

World leaders are primed to meet in New York in two weeks for a UN summit to discuss options to reduce emissions of climate warming gases.

This report is the latest evidence of the levels of atmospheric gases burning fossil fuels has released.

A leaked draft of the UN’s IPCC climate science panel syntheses report, due out in November, stressed that “human influence on the climate system is clear”.

Earlier this year the Mauna Loa observatory in Hawaii recorded for the first time in recorded history that concentrations of carbon dioxide in the atmosphere had passed 400 parts per million (ppm).

Report: Alaska fisheries hit by rising acidifiction levels

Equally concerning, WMO scientists said the ability of the biosphere to absorb rising carbon levels had diminished, leaving the oceans to compensate.

“The ocean cushions the increase in CO2 that would otherwise occur in the atmosphere, but with far-reaching impacts,” it said in a press release.

“The current rate of ocean acidification appears unprecedented at least over the last 300 million years, according to an analysis in the report.”

Caused when the oceans suck in CO2, acidification is likely to lead to the decline of corals, algae, molluscs and some plankton, say scientists.

The ocean currently absorbs around a fourth of manmade CO2 emissions. The WMO said if emissions continue to rise, acidification is likely to accelerate until the 2050s.

Earlier this year the IPCC said ocean warming and acidification linked to rising CO2 levels would undermine food production and threaten the world’s poorest people.

Wendy Watson-Wright, executive secretary of the Intergovernmental Oceanographic Commission of UNESCO welcomed the WMO’s focus on oceans in its report.

“The inclusion of a section on ocean acidification in this issue of WMO’s greenhouse gas bulletin is appropriate and needed,” she said.

“It is high time the ocean, as the primary driver of the planet’s climate and attenuator of climate change, becomes a central part of climate change discussions.”

How Fishing Makes You A Better Person (According To Science)

 

Fishing is one of the most accessible outdoor sports. Nearly anyone, no matter age, income level or even fitness ability, can easily participate. And the sport is no longer the boys’ club it was once thought of either. Of the 46 million Americans who fish today, over one third of them are women, according to a new report released by the Recreational Boating and Fishing Foundation and the Outdoor Foundation. There’s also growing age and ethnic diversity within the sport.

Whether they grew up heading out onto the lake every Sunday with Grandpa or are one of the millions trying the sport for the first time every year, those who fish have a direct connection to health and well-being. Here’s how fishing can help you lead a happier, healthier life.

Fishing can keep you physically fit.
While fishing itself isn’t necessarily going to get your heart rate up, many of the best fishing spots require a bit of paddling, biking or hiking to reach, all of which have proven cardiovascular benefits. “You can make your fishing excursion as physical as you want,” Janna Superstein, president of fly fishing company Superfly International Inc., tells The Huffington Post. She stresses, however, that you don’t need to be incredibly active to participate. “Even just getting out there, you’ll still get the benefits of the outdoors and maybe that’s the beginning of a new fit, healthy lifestyle,” she says.

Of course, just spending time outside is good for your body and your brain. The outdoors gives us plenty of vitamin D (but don’t forget the SPF!), makes us happier and helps us age gracefully.

Fly fishing — a specific type of fishing that incorporates artificial “flies” and a weighted line — may also help women with breast cancer recover. Groups like Casting for Recovery combine breast cancer education with the sport as a form of support, therapy and exercise. Casting for Recovery’s site says that the gentle motion of fly casting resembles exercises often prescribed after surgery or radiation to promote soft tissue stretching. The group is designed for women of all ages in all stages of treatment and recovery.

Fish are an excellent source of nutrition.

While not all who fish keep what they catch, those who do may be in for some bonus benefits. Fish is an excellent source of omega-3 fatty acids, which may decrease blood pressure and lower the risk of stroke and heart failure. They could also reduce irregular heartbeats and improve brain function in children, according to the Mayo Clinic.

In addition to heart and brain health, research shows that eating fish can save your eyesight, decrease the risk of asthma, protect your skin from UV-rays and cut your chances of developing rheumatoid arthritis in half. Some research suggests that eating a fish-heavy diet could even help reduce the risk of breast cancer.

Eating fish could help you live longer.
All of that healthy eating pays off. Some credit the long lifespan of the Japanese to a fish- and veggie-heavy diet. Japanese women have the longest life expectancy in the world, at 87 years, according to the World Health Organization. And while men in Japan aren’t quite as lucky, they do live to an average age of 80.

Fishing may reduce stress.

Many fishermen (and women!) would agree that the gentle lapping of waves and tug on a fishing line is enough to push any stress far from the mind. “Just doing the activity relieves pressure and creates sense of excitement,” Frank Peterson, president and CEO of the Recreational Boating and Fishing Foundation, tells The Huffington Post.

Of the nine percent of Americans currently considering taking up the sport, 38 percent of them are interested in it as a means of relieving stress, according to the Recreational Boating and Fishing Foundation and the Outdoor Foundation report. In a country where 80 percent of us report feeling even more stressed or equally stressed each year and only 37 percent of us actually think we’re doing a good job at managing it, finding a way to relax is vital to our mental and physical health.

For many, a day of casting line is the answer because research shows that focusing on any one activity at hand can be a fast track to stress reduction. “When you’re fishing, you have to be mindful,” Superstein says. “You have to be present in order to observe what’s happening with the fish and catch them.”

The sport may decrease symptoms of PTSD.
The combination of mental relaxation and an easy form of exercise could also help those who suffer from post traumatic stress disorder. A 2009 study shows that fishing can lower PTSD symptoms and increase the mood of those who suffer from the disorder. After three days of fly fishing, participants reported a 32 percent reduction in guilt and a 43 percent decrease in feelings of hostility. The feeling of fear was also reduced by 30 percent, and sadness dropped by 36 percent. A portion of these positive effects remained even a full month after the fishing retreat.

Plus, it helps you unplug.
pool of fish
Some of the mental benefits of fishing may be thanks to the opportunity it offers for us to unplug from our digital lives and enjoy nature. Sure, many love to snap shots of their big catches for various forms of social media or to print off and frame the old-fashioned way — “Before there were selfies, there were ‘fishies’,” says Peterson. And 50 percent of us use technology — whether for music, pictures or GPS — when participating in outdoor activities, according to the Recreational Boating and Fishing Foundation and the Outdoor Foundation. But overall, fishing offers a way to cut back on screen time. “It gives us a chance to unplug from daily lives and plug into something completely natural,” Superstein says. “We can then recharge our batteries in a natural way.”

Interested in taking up the sport yourself? So you’re ready to feast on a fresh catch. Luckily, it’s easier to start fishing than you may think. We talked to an expert to find the best tips for beginner fly fishers:

  • First, get rid of the misconceptions. Contrary to popular belief, fly fishing isn’t only done for trout in mountain streams. According to Superstein, you can actually do it in saltwater, lakes, ponds and rivers.
  • Invest in a starter kit. If you’re a total newbie, look into buying a starter kit that includes a rod, reel, line and flies. Some even come with the necessary knots already tied. And don’t feel like you have to spend a fortune, Superstein says. “Spending more money on gear doesn’t necessarily mean you’re going to catch more fish.”
  • Ask the experts. From weather to season to type of fish, there are so many variables to take into account that Superstein cautions against sticking to any hard and fast rules for catching more. Instead, check with people who know the area. Ask fellow boaters, workers at the bait shop or members of local fishing clubs for the best spots to fish and the best type of bait or fly to use.
  • Explore the waters close to home. There’s no need to venture into the depths of the woods or up a mountain to a small trout stream. Fishing is likely more accessible than you think. You can fish in the heart of downtown Chicago or on the Hudson River in New York City and still get the benefits of nature while living in an urban setting, Superstein says.
  • Go whenever you can. While some only fish in the early morning and others swear by the first thaw of spring, Superstein warns against letting these restrictions hold you back. If you want to fish, go fish. “To quote my father,” she says. “‘The best time to fish is whenever you can,’ because for the most part, it’s not about the fish, it’s about getting out on the water.”

El Niño forecast is up in the air for Southern California

drought-photos-20140619-022

With the summer winding down, weather officials say the winter forecast is wide open.

While a mild-to-moderate El Niño weather pattern is widely expected to develop in the fall, forecast models have “projected many different outcomes,” said Eric Boldt, a meteorologist with the National Weather Service.

“The odds of drier than normal winter are just as high as a wetter than normal winter,” he said in a video released Tuesday.

Last month, climatologists downgraded the chance of El Niño forming this fall from 80% to 65%. But the latest three-month outlook for January to March shows a potential for above-normal precipitation in Southwest California, Boldt said.

Forecasters are in El Niño watch mode, noting that sea temperatures along the equatorial Pacific have warmed, a possible signal that the storm-producing weather system is strengthening, Boldt said.

In the last four weeks, sea surface temperatures were also above average along the eastern equatorial Pacific Ocean.

El Niño winters in Southwest California have been historically wet, which would be a welcome reprieve for a region parched by a prolonged drought.

Nearly 60% of the state is experiencing “exceptional” drought conditions, the harshest on a five-level scale as measured by U.S. Drought Monitor.

CHUCK DELLA SALA, JOE PENNISI, AND SHEMS JUD: Sustainability Certification Reflects Sea Change in West Coast Fisheries

1

September 4, 2014 — In essence, what the trawlers of the West Coast have done under this new system is renew the social contract that they have with the public, by providing assurance that they are harvesting a public resource in a sustainable manner.

The following op-ed was submitted to Saving Seafood by Chuck Della Sala, the Mayor of the City of Monterey, California; Joe Pennisi, the owner and skipper of the F/V Pioneer; and Shems Jud, of the Environmental Defense Fund’s Oceans Program:

Most California seafood lovers are familiar with the Monterey Bay Aquarium’s Seafood Watch Consumer Guides – the booklets that recommend which fish to eat and which should be avoided.

Seafood Watch just dramatically increased its list of recommended seafood options from the West Coast. They now rank nearly all bottom trawl-caught groundfish as “good” and “best” alternatives. Those species include lingcod, chilipepper rockfish, Dover sole, and dozens more.

Readers accustomed to grim news about marine resources will find this news a pleasant surprise; but for those who closely follow commercial fisheries of the West Coast it may seem more like a miracle.

Fourteen years ago the West Coast groundfish fishery was declared a disaster by the federal government. Years of overharvesting and science and management failures had resulted in rapidly dwindling stocks as too many boats chased too few fish in a classic example of the “tragedy of the commons.” Eight species were declared overfished, and the Pacific Fishery Management Council (Council) and the National Marine Fisheries Services were scrambling – along with fishermen – to figure out some way to save a major American fishery, and one of great importance to Monterey and the region.

There’s nothing like disaster to bring unlikely partners together. In the years following the declaration it has been our privilege – fishermen, fishing communities, and conservationists, to sit together at the same table with the Council and the National Marine Fisheries Service to help develop an entirely new approach to managing one of the most complex multispecies fisheries on earth.

The quota-based management system that was eventually implemented in 2011 became known as the West Coast Groundfish Trawl Catch Share Program. It combined practical conservation incentives with a system of full accountability by putting federal observers on fishing vessels.   The program gives fishermen the flexibility to fish when the weather is right and to work with their markets to time landings to meet demand. Fishermen are also able to actively manage their portfolio of species, which has dramatically reduced both bycatch and discards.

Today, fishing businesses are slowly becoming more stable, and several of those overfished species are rebuilding at a surprisingly rapid rate.

In essence, what the trawlers of the West Coast have done under this new system is renew the social contract that they have with the public, by providing assurance that they are harvesting a public resource in a sustainable manner. The recent assessment from the Seafood Watch Program, and the June certification of thirteen species of West Coast groundfish as sustainable by the Marine Stewardship Council, verifies that.

This is an unfolding success story; West Coast fishermen still face stiff challenges. They have to pay for those observers and bear much of the cost of administering their catch share program. But the announcement by Seafood Watch signifies a remarkable course change in this fishery, a change that California seafood lovers – and that’s everybody reading this, right? – can be proud of.

D.B. Pleschner: State’s wetfish industry solid, sustainable

http://www.losangelesregister.com/articles/california-604383-fisheries-wetfish.html

laregister

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 make 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, or 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 nearby 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.

Beyond the history, the culture and the 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.

INNOVATIVE LAB GAUGES ACIDIFICATION EFFECTS ON MARINE SNAILS

Carbon dioxide scrubbers like those that clean the air in space stations.

Precision monitors and instruments.

Industrial parts used in wastewater treatment.

Michael Maher’s job was to assemble the pieces into one of the most sophisticated ocean acidification simulation systems yet developed. Ocean acidification is the decrease in ocean pH due to its absorption of carbon dioxide from the atmosphere – carbon dioxide forms an acid when it dissolves in water.

“You have tools available – they may not be designed for this purpose but you can try to make them all work together,” said Maher, a research biologist at NOAA Fisheries’ Northwest Fisheries Science Center in Seattle. “There wasn’t a blueprint or a kit you could order because nobody had really been trying to do this kind of thing before.”

The system that Maher and the ocean acidification research team built in the Science Center’s parking lot has provided new insight into the impacts of future ocean conditions on marine species. Researchers used it to examine what happens to small marine snails from Puget Sound when exposed to both current ocean conditions and the acidified conditions expected in the future. The research is described in a new paper in the online journal PLOS ONE reporting that current West Coast ocean waters are acidified enough to dissolve the shells of the snails, called pteropods.

The finding is not a surprise: Another NOAA-led team reported in April that shells of pteropods in near-shore habitat on the West Coast show signs of dissolution due to acidified waters. What is important about the new research is that it measured the extent of shell damage at escalating carbon dioxide concentrations, each translating to a different degree of acidification, in a controlled laboratory environment said Shallin Busch, a NOAA research ecologist.

The findings are a first step toward using the pteropod species examined in the study as a living barometer or indicator of ocean acidification along the West Coast.

“Our findings are a piece of the puzzle,” said Busch, the lead author of the new paper. “Now we know, yes, pteropods from the North Pacific are sensitive to ocean acidification. Now that we have confirmed their sensitivity, we need to look more closely at how pteropods are responding to current ocean conditions and what may happen in the future as carbon dioxide increases.”

Pteropods provide important nutrition for whales, seabirds and fish such as herring, salmon and mackerel, so changes in their populations could rattle through the marine food chain. Carbon emissions during the industrial era have lowered the average global ocean pH from 8.2 to 8.1, turning oceans slightly more acidic. West Coast waters are naturally acidified compared to other parts of the ocean so they may affect marine life such as pteropods sooner than acidifying waters elsewhere in the world.

The research also demonstrated the capacity of the NWFSC’s ocean acidification system to hold marine life at different carbon dioxide concentrations for extended periods. The system can control temperatures, oxygen levels and light for even more precise management of conditions during experiments.

“They are all dependent on each other – if you change the temperature, the pH will change,” Maher said. The system that carefully manages all the variables is “ a combination of machines and precisions instruments.”

The comprehensive controls allow researchers to isolate acidification as the cause of the shell damage, ruling out other factors that might otherwise be at play in a natural environment.

“There are not a lot of cases where we can definitively say, ‘This change is the result of acidification,’” said research ecologist Paul McElhany, Busch’s colleague at NWFSC. “It’s very hard to disentangle unless you know that’s the only thing changing. Experiments like this provide evidence about the effects of acidification alone.”

Busch said each member of the research team – Maher, McElhany and NOAA Hollings Scholar Patricia Thibodeau – brought individual skills to the research. The team has also developed a smaller and transportable version called a Mobile Ocean Acidification Treatment System, or MOATS that could be carried in the field or aboard research ships.

Thibodeau joined the research team for the summer of 2012 after her junior year at Bowdoin College in Maine. One of her initial tasks was to collect pteropods from Puget Sound by boat at night to stock the experimental system. Pteropods ascend in the water column at night to feed. The vertical movement naturally exposes them to varying carbon dioxide concentrations, which the ocean acidification system can simulate.

Later Thibodeau helped examine the shells of pteropods exposed to different concentrations of carbon dioxide. As with most science experiments where objectivity is paramount, she did not know which ones had been exposed to which concentrations when she rated the extent of damage to each shell.

“Sometimes biology can be so unpredictable, but this had such a clear outcome and relationship, it was very interesting to be a part of,” said Thibodeau, who just began work on her PhD at the Virginia Institute of Marine Science. “There is definitely a human component to the issue because so many of us eat oysters and clams and other species affected by ocean acidification. So what we know and what we do really makes a difference.”

Sardine lover meets his match at The Taste’s ‘Fish Fight’

la-dd-sardine-the-tastes-fish-fight-20140902-001Michael Cimarusti, left, the gracious winner, and the still-happy loser. (Jenna Schoenefeld / Los Angeles Times)

| Copyright © 2014, Los Angeles Times

I like almost everything about sardines. I like to cook them, I like to eat them. Heck, when I visit aquariums I even like to watch them swim around in circles. That’s the only explanation I can offer for how I found myself standing on a stage Sunday night engaged in a cook-off with one of America’s great chefs.

In the final night of this year’s The Taste, Michael Cimarusti from Providence and I were engaged in what we decided to call “The Great Fish Fight,” and the subject was sardines. He won, of course — I told him at one point it was like me playing H-O-R-S-E with Kobe Bryant — but I did get to cook some sardines, so the event wasn’t a total loss on my part.

The whole thing started innocently enough at last year’s Taste when food blogger Sara O’Donnell (Average Betty) tried to instigate an argument between Cimarusti and me about who had the better beard. No vote was taken, but I do think I won by a landslide as people tend to favor elegance over volume.

When she tried to kick up a similar fuss this time around, Cimarusti — perhaps chastened after last year — suggested that instead we should have a sardine cook-off. “Fish-ticuffs” I called it. And, of course, since the whole thing played out in real time on Twitter, there was no way I could back down.

My first challenge was finding sardines to cook. That proved harder than expected. Sardines are a notoriously fickle fish, their population prone to booms and busts. (Interestingly, some marine biologists — and many fishermen — have proposed that there is a sardine-anchovy cycle, with each fish taking dominance over the other for periods of time.)

In good times, sardines are one of the great bargains in the fish market — usually around $2 a pound. We’re in a down cycle for sardines, so I was stymied when I tried to sneak in a little practice beforehand. All my usual suspects, where sardines have been so plentiful in the past, turned up dry.

I ended up using a sardine-like fish I found at Seafood City called something like “Roundhead Scad.” At least I got some practice cleaning — and it actually tasted good.

Cleaning is a big part of sardine cooking. Unlike most fish you buy in the market, sardines are always sold in the round and in their entirety. Cleaning them is not hard, but it is not like buying the usual fillet. Think of it as the difference between cutting up a whole chicken and buying a boneless, skinless breast.

I find sardines react really well to grilling and pair well with big flavors. When I cook them (and maybe I learned this from Cimarusti, years ago — I’ll give him credit anyway), I like to grill them on the skin-side only until the flesh turns color all the way through. This way the skin crisps up nicely, a real plus.

As far as accompaniments, with it being the height of the summer harvest, I decided to pair them with a salad of tomatoes, cucumbers and white beans, served with a nice drizzle of a quickly made pesto. It was like a panzanella, but with firm beans instead of tender bread.

Cimarusti opted for another of my favorite sardine dishes, the Sicilian classic pasta con le sarde — sardines mixed with spaghetti, wild fennel fronds and bread crumbs. And he knocked it out of the park.

The judges — KCRW “Good Food” host Evan Kleiman and our own Jonathan Gold — were kind, but it was clear that this was a perfect example of the difference between a good home cook’s dish and what a master chef like Cimarusti can do.

Still, all was not lost — I did get what I think of as my Little League “hardest-trier” award. Afterward Cimarusti gave me all the leftover sardines we hadn’t cooked.

So Monday night, I grilled them. Defeat has never tasted so sweet.

In massive nod to success of West Coast industry and managers, Monterey Aquarium upgrades 21 species

In a massive nod to the success of US fishery managers, Monterey Bay Aquarium has upgraded its consumer guide on 21 west coast groundfish and rockfish species.

It now says all of these species – including sable fish, many species of rockfish sold as snapper in California, the various species of flatfish and other bottom trawl fish including Dover sole, petrale sole, starry flounder and sand dabs,  are rated either ‘best choice’ or ‘good alternative’.
“This is one of the great success stories about ecological and economic recovery of a commercially important fishery,” said Margaret Spring, vice president of conservation and science, and chief conservation officer for the Monterey Bay Aquarium.
Although Monterey Bay calls this “the most dramatic turnaround to date’, it actually reflects business as usual for the US fishery management system.
The West Coast groundfish fisheries were declared an economic disaster early in 2000, when landings and fishing income plummeted.  Many species were listed as being overfished, and in some cases bycatch limits on types of rockfish came down to virtually single fish.
“The turnaround in such a short time is unprecedented,” said Jennifer Dianto Kemmerly, director of the Seafood Watch program. “Fishermen, federal agencies and our environmental colleagues have put so much effort into groundfish recovery, and now we’re seeing the results of their work.”

In fact, the credit should go to the Pacific Fisheries Management Council, the Pacific States Marine Fisheries Commission, NMFS, and the industry that worked with them, along with the rationalization program that allowed for effort reductions to make the fishery more economically viable.
Although the Aquarium as an NGO credits the changes to the Magnuson act in 2006, actually the seeds of the recovery were planted much earlier.  The West coast and Alaska fisheries operated with hard TAC’s long before they became mandatory across the entire U.S.

Like other US fisheries management success stories, the recovery of West Coast groundfish and rockfish species relies on two primary principles that have been fully embraced by the seafood industry:
*scientifically set quotas for the total allowable catch, and
*comprehensive bycatch management based on industry formed cooperatives and real time bycatch reporting.

A third factor, beyond anyone’s control, has been the favorable environmental conditions on the West Coast that have allowed for stock recovery once the other two actions were in place.

Unfortunately, where the environmental conditions move against a fishery – as is happening in New England cod, the best fisheries science in the world cannot speed up a recovery.  However, fish history is replete with many species suffering declines to near zero abundance, and then recovering sharply as conditions improve.   Haddock in New England is a prime example, with the biomass recovering to levels not seen seen in 40 years.

In future articles we will document more about how this recovery took place, and the hard work that went into it.  But like the rooster who thought he caused the sun to rise, it is important for buyers to recognize that the rooster – in this case the Aquarium’s Seafood Watch – is announcing an event that was brought about through scientific management  and industry cooperation and discipline.

That is why for the seafood industry, it is great to have the recognition, whether it be MSC or the Aquarium or other recommend lists, but just like the rooster and the sunrise, the accolades are for the work we’ve already done, they are not the cause of the success.
