Securing sustainable seafood is a convoluted prospect at best. That statement applies whether you are the individual harvesting groundfish from the ocean’s floor, farming shellfish in local estuaries or buying wild salmon at the fish counter.

Buyers have to be “well versed in the adjectives (and colors) needed to ensure they are really buying sustainable seafood,” says Sheila Bowman, manager of culinary and strategic initiatives at the Monterey Bay Aquarium.

Organizations such as the Monterey Bay Aquarium, National Oceanic and Atmospheric Administration and National Geographic have built seafood buying guides called Seafood Watch, FishWatch and Seafood Decision Guide, respectively. These guides employ green, yellow and red visual cues to advise consumers which fish are sustainable choices. Those ratings are based primarily on species population numbers and how pulling those fish from the ocean affects the overall marine ecosystem.

According to Barton Seaver, a longtime sustainable seafood advocate, seafood buying guides represent a good start. They help eaters choose the types of seafood the oceans can afford to give (those with green ratings and sometimes yellow), as opposed to the ones (red ratings) that may be overfished.

Seaver serves in a dual capacity as director of the Healthy and Sustainable Food program at the Harvard School of Public Health’s Center for Health and the Global Environment and as a sustainability fellow at the New England Aquarium in Boston. He argues that issues of economic viability for the fishermen, cultural preservation of fishing communities and the overall health of seafood eaters must also be taken into consideration when assessing seafood sustainability. Pulling these multiple elements of the sustainable seafood picture into focus will require advanced technology.

Seaver, Bowman, Steve Eayrs, a research scientist with the Gulf of Maine Research Institute, and Shah Selbe, an aerospace engineer and National Geographic Emerging Explorer, can readily point to technologies they believe are changing the sustainable seafood landscape. Their suggestions fall into three categories: making fishermen more efficient at harvesting fish in a sustainable fashion; cracking down on illegal fishing; and providing eaters with a reliable means of tracing where the fish on their plate came from and how it arrived there.

Technology No. 1: Precision Fishing

Smart Catch Technologies is a company co-located in Newport, Ore., and Palo Alto, Calif., that creates products to support sustainable commercial fishing. Seaver pointed to the company’s CatchCam and SmartNet products because they enable “precision fishing,” a scheme under which non-target fish are released from nets before they are hauled ashore, thereby reducing both bycatch and waste.

Technology No. 2: Revamped Bottom Trawling Gear

Bottom trawling is the practice of towing a funnel-shaped net anchored open by two “doors” that have continuous or occasional contact with the ocean floor. Trawls catch shellfish and groundfish found near the seabed, and they have long been criticized for entrapping everything in their path, including sponges, corals and non-target species. Eayrs cites a recent study conducted by his institute showing that changes in the trawling gear — in how the doors are constructed to minimize contact with the floor and changes both in the size of the net holes and the materials from which they are constructed — reduce seabed impact by as much as 95% and yield a 12% reduction in fuel consumption with little or no variation in the targeted cod catch. If eaters are educated enough to be able to accept the premise that the fish was caught legally using the best available science, “then they can buy their cod with confidence,” Eayrs said.

Technology No. 3: GPS-Enabled Selective Trawling

According to Bowman, establishing a trawling footprint — clearly articulating which parts of the ocean floor can or can’t be open to trawling — and having fishermen (and enforcement agencies) use GPS technology to make sure fishermen do not drop their nets within a set distance from protected areas, is a use of technological application that holds the most promise for helping to feed the planet’s 9 billion people. “But it will also likely raise the most controversy on what the ocean can continue to give up for the sake of human consumption,” Bowman said.

Technology No. 4: Cheap Open Source Gear Helps to Decrease Illegal Fishing

In his recent lecture at the New England Aquarium, Selbe outlined FishNET, a project that focuses on developing integrated, low-cost technology solutions that help improve the ability to observe and collate data about illegal, unreported and unregulated fishing (IUU). This suite of technologies comprises a Web-based data collection server, off-the-shelf drone and cellphone equipment, and cheap, open-source monitoring devices that together capture and analyze official and crowdsourced data on fishing vessels and exploited areas.

Technology No. 5: Sophisticated Satellite-Enabled Poaching and Dumping Surveillance

Seaver points to companies such as Windward and SkyTruth to illustrate the role of satellites in vessel tracking and how these efforts can help with all IUU issues and enable better fisheries management.

Technology No. 6: Bar Codes for Near Real-Time Seafood Supply Chain Tracking

Norpac Fisheries Export is a successful processing and distribution business that has developed and implemented traceability software to track fish from catch to retailer. Through the use of bar codes and back-end software, this system lets sellers and buyers know where their fish are at any point in the process, letting them pinpoint procedural inefficiencies and keeping illegally caught fish out of the chain. Seaver also points to the emerging field of DNA bar coding as a possible evolution. “Whoever invents a hand-held tissue sampler that can accurately ID a species on the spot will win big!” he said.

Technology No. 7: Sustainable Seafood Matchmaking

Colorado-based FishChoice Inc. has built an online matchmaking service for buyers and suppliers of sustainable seafood. According to Seaver, this service opens up the chance to distribute and purchase sustainably sourced products and streamlines recommendations and certifications from the NGO community. “The service … provides education and the opportunity to conduct the transaction right there,” Seaver said.

Technology No. 8: Storied Sushi

Owners of San Diego-based Harney Sushi have developed edible quick response codes (QR) — made of rice paper and edible ink — that customers can scan with their cellphones before eating any fish served to them. The codes link back to NOAA’s FishWatch database. “By demanding this kind of detail, we help send a message to suppliers that they need to know and verify their seafood sourcing,” Seaver said.

Freshly shucked Blue Point oysters. Credit: Sofia Perez

As we approach the floating dock, Chris Quartuccio cuts the boat’s engine, and the steady hum of the motor is replaced by what sounds like a large pile of broken plates being raked. We’ve reached Blue Island, Quartuccio’s oyster farm out on New York’s Great South Bay, the 29-mile-long body of water sandwiched between Fire Island and Long Island’s South Shore. On the other side of the dock, one of his employees is tumbling oysters, vigorously shaking mesh bags filled with the bivalves before stacking them in an open rack to be lowered back into the bay, where the oysters will continue to grow.

Tumbling heightens what wild oysters would naturally endure as they are tossed around by the tides, rasping off their still-feathery edges to produce the relatively smooth shells that are served up on ice at raw bars. Having spent the day listening to Quartuccio discuss the history of the region’s shellfish industry, however, it’s hard not to see tumbling as a metaphor for the trade and the lives of the people who ply it. Ebb and flow is putting it gently; it’s a saga filled with hope, desperation and Mother Nature’s merciless logic — from boom to bust to boom again, repeat ad infinitum.

Although he’s only 48, Quartuccio has lived through a few of these cycles already. A native of Sayville, N.Y., he started digging for clams when he was 12. “Back then, clam diggers here were making a lot of money. The better ones lived in the same neighborhoods as the doctors and lawyers. But as more people got into the business, they started putting a lot of pressure on the bay.” To maintain their high incomes, many began to work the winter grounds illegally, targeting areas of the bay that were rich in shellfish but that also served as important spawning zones. By the 1990s, the population of hard-shelled clams was wiped out.

Reviving the real Blue Point oyster

During my visit, Quartuccio takes me to Blue Point, the spit of land for which the renowned oyster is named. In 1908, New York state decreed that in order to be sold as a Blue Point, an oyster had to have spent at least three months in the Great South Bay — though the law is rarely enforced, and it’s not uncommon to see menus with oxymoronic offerings such as Chesapeake or Connecticut Blue Points.

Like clams, oysters here have had a checkered history, periods of great abundance followed by foreseeable — and unforeseeable — decline. “This area was paved with oysters back then,” said Quartuccio, referring to the first third of the 20th century, but things changed after the great hurricane of 1938, dubbed the “Long Island Express.” Killing more than 600 people, the storm destroyed large parts of Fire Island and created numerous inlets into the bay, causing the oyster beds to be silted over.

Later attempts to get the industry going again were foiled by brown tides, the result of excess nitrogen in the water, as well as the appearance of parasitic diseases that — although not a danger to consumers — decimated the oyster population. In 2002, a local fish hatchery manager was quoted in The New York Times as saying the Blue Point oyster had likely reached its end.

Or had it? Predictions of its demise appear to have been premature. Thanks to seeding efforts and laws prohibiting the harvest of the youngest oysters, parts of the bay have become hospitable again. Quartuccio purchased his farm back in 2005 (he owns the dock and leases his prime underwater location from the town of Islip), and his company now sells its delightfully briny, firm-textured Blue Points to a roster of high-end restaurants that includes New York’s Four Seasons, Craft and Momofuku and San Francisco’s Waterbar.

Serving them up ‘Naked’

Despite his success, Quartuccio has learned to avoid putting all his shells in one bucket. In addition to his Blue Points, which he sells under the name “Blue Islands” — to distinguish them from competitors who’ve appropriated the original name for their oysters — he also deals in oysters from other parts of the country. And he’s always looking for the next big thing to promote.

To make a good living in the industry, he tells me, marketing is key. “If you don’t have the right name, I don’t care how good the oyster is. It’s not gonna sell,” he noted. With his newest item, a diver-harvested oyster from Long Island Sound, it appears he’s hit the jackpot. Christened after Times Square’s most famous tighty-whitey-clad denizen, the “Naked Cowboy” is Blue Island’s best-selling oyster to date. “When customers see the name on menus, they tell their waiters, ‘I want to know what the Naked Cowboy tastes like.’ That happens all the time.”

Although these calculations may seem crass to some, the economic realities of the industry defy the landlocked’s tendency to romanticize a seafaring life. These days, Quartuccio spends more time in the office than out on the water, but when I ask him whether he misses that part of the job, he smiles. “I’ve seen so many sunrises and sunsets. And when I say that, I mean they were long days. When you’re out here, day after day after day, in all kinds of weather — from 100 degrees to watching the ice form on the tips of your fingers … ” he explained, the echo of his Long Island accent hanging in the air for a moment. “I’ve seen enough for a lifetime.”

Fishing in the South Indian chaakaras during monsoon season. Credit: Prasanth Gulfu

The southwest monsoons arrive in Kerala with all their fury by mid-June every year. For the following 2½ months, raging seas, heavy rainstorms and rumbling thunder reign. Monsoon is also the lifeline of the region where food production and harvesting are still deeply seasonal. It is the time of renewal of the life cycle of farming and monsoon fishing.

The strong winds and high waves during monsoon season make it impossible even for fishermen with motorized trawlers to go out into the deep sea. But for the artisanal fishermen in Kerala, the early days of monsoon are the much-awaited time for Chaakara, the mud bank formations that arise along the coast within a few days after the onset of southwest monsoons. Chaakara is a welcome geological occurrence that happens only along Kerala’s coast in India.

Chaakara, or mud bank formation

The violent winds and strong ocean currents created by the monsoon winds stir the bottom of the sea, and fine mud particles are churned up into a thick suspension. The southerly currents that run parallel to the coast at maximum speed drive the entire floating mud slowly towards the shore. A semicircular boundary develops around the suspended mud, which consistently absorbs the wave energy and substantially reduces turbulence. Kerala has an intricate network of interconnected rivers, canals, lakes and inlets including five large lakes linked by canals, fed by more than 40 rivers that extend virtually half the length of the state.

During monsoon rains, clay and silts rich in silica and organic matter are washed down from the mountains and are carried down the rivers to the lakes and then on to the sea. Muddy water attracts a wide variety of fish, shrimp and prawns in abundance, and they surge to the surface from the bottom of the sea where they normally live. The tranquil waters inside the mud bank turns into a bustling fishing harbor.

Kerala’s fisheries and aquaculture resources are rich and diverse, and Kerala accounts for 20% to 25% of the national marine fish production. Fish catches from the state include more than 300 species, such as sardine, mackerel, seer fish, pomfret and prawn.

Artisanal monsoon fishing

Chaakara is the seasonal windfall for artisanal fishermen. Heavy surf and turbulent waters are dangerous for small canoes and catamarans and fishing in the artisanal sector is generally at a standstill during the monsoon. Thousands of fishermen from the surrounding areas rush to the fishing village where Chaakara has surfaced. In this safe and hospitable environment they harvest shoals of fish from their traditional fishing canoes. During the short-lived chaakara season the shore is lined with fishing canoes and catamarans and fishermen landing, sorting and selling a wide variety of fish. A single throw of nets enables them to bring home a miraculous bumper harvest of mackerel, prawns, sardines and others. Seafood processors and exporters buy up the bumper crop and cash in on the abundance. The price of seafood drops to attractive levels.

The breeding season of the majority of the fish varieties coincides with the south-west monsoon season in Kerala, and it is essential that trawling is stopped during this period because it destroys fish eggs and young fish. The trawling ban is also necessary to ensure the safety of fishermen as the seas turn very rough during the monsoon.

Kerala has pioneered a fisheries management technique, an annual 45-day ban on trawling in the state’s waters during the monsoon season since 1988, for the long-term conservation of marine resources. This ban creates a major boon for artisanal fishermen because they get exclusive rights to fish in the vicinity of mud banks during this period.

The chemistry of chaakara

Chaakara is a unique phenomenon that happens along a stretch of nearly 270 kilometers (160 miles) along the Kerala coastline. At times these mud banks run several kilometers long, taking on the size of a lake. After a few weeks the fluid mud settles at the bottom, dissipating the mud bank. The mud bank formation is erratic and varies from year to year, in location, extent and duration.

One theory about the abundance of marine life close to the shore is that the muddy waters at the bottom of the sea contain less oxygen, so fishes and prawns that live at the bottom of the sea swim up to the surface to catch a breath. Veteran fishermen have a different take. They believe the rich nutrients from the mountains carried down by the rivers and backwaters attract fishes to the calm area formed in the sea.

Whatever the reason, it’s the perfect time to take advantage and make dishes served up by the monsoon’s bounty.

Prawn Cutlets

The following recipe is adapted from “The Essential Kerala Cookbook” by Vijayan Kannampilly

Ingredients

1 pound medium-sized prawns

¼ cup rice flour

Salt to taste

3 to 4 green chili peppers thinly sliced (less for milder taste)

1½ inch piece of fresh ginger grated

⅓ cup thinly chopped shallots

¼ cup curry leaves, thinly chopped

2 cups of oil, preferably coconut oil

Directions

1. Shell and remove heads of the prawns. Devein them and wash well. Place the prawns in a pan along with ½ cup of water and cook till tender. Remove from the stove, drain any remaining water and cool.

2. Grind or mince the prawns in a food processor. Add rice flour, salt, green chilies, ginger, shallots and curry leaves, and mix well. Divide the mixture into small 1-inch round balls and shape into round cutlets.

3. Meanwhile heat the oil in a frying pan to 350 F. Deep-fry the cutlets till both sides are golden brown. Serve hot.

Salmon. Credit: G215/iStockphoto

For most Alaskans, summer means experiencing 24 hours of daylight each day and time for spotting bears. For many folks in the rest of the United States, Alaskan summers mean the return of wild salmon. Fattened for their trip up their birth rivers to spawn after roughly one to five years in the ocean, these oily, nutrient-rich fish are a delicacy in the Lower 48, often costing well over $10 per pound.

Smoked, grilled, baked or canned, Alaska’s wild salmon have a strong, distinct flavor. Those people who claim they can’t tell the difference from farmed salmon have probably been fed an inferior species — commonly, salmon marketed as Atlantic salmon is farmed.

When you’re purchasing your salmon, you should know what you’re getting. The following is a primer on the five types of Pacific salmon. The first three — king, red and silver — are considered the best and are therefore the most expensive. Many Alaskans view pink and chum, while certainly edible, as inferior to the former three, but that is generally because of the abundance of the former three, rather than a lack of quality of the latter two.

King (Chinook): These are the granddaddies of salmon and one of the most prized catches. The largest of the Pacific wild salmon, kings are valued for their rich flavor and firm texture as well as their massive size (they usually do not weight less than 30 pounds; the record weight is 97 pounds). Kings from the Yukon are particularly prized because they are rumored to be fattier, thanks to cold temperatures and a long migration. Kings are excellent smoked, but also taste great grilled, baked, poached or any other way you can think to cook them up.

Red (Sockeye): Another highly valued Pacific salmon, reds are not as large as kings but have a rich, deep color and a high oil content. Flavorful and beautiful, red salmon present well on the plate and their density makes them a favorite for sushi. This fish also pairs well with other strong flavors.

Silver (Coho): Silver salmon are another favored wild salmon. Aggressive and fast, these smaller fish (averaging 10 pounds) congregate at the mouths of rivers to wait for appropriate weather or high tide. They are popular with sport fishermen, and their meat is also prized. Silver salmon’s flesh is more orange than red, and it has a mild flavor, with the firm flesh that is typical of the top three types of Alaska wild salmon. It is a favorite for grilling and canning.

Pink (Humpy): Pale in color and light in texture, the pink salmon has a low fat content compared to kings, reds and silvers. It is the smallest of the five Pacific salmon, averaging 3 to 5 pounds, and the most abundant, so it is easily caught and processed. Pinks are usually canned and sold in Europe and the South, and big blocks of the meat are also shipped to China. (Alaskans are notoriously snobby about their salmon and tend to stick to the three more popular varieties.) Pinks are an excellent source of protein.

Chum (Dog): The least desirable of the five Pacific salmon, chum have the lowest market value and are often sold to foreign markets. Though they are not as firm and rich as king, red or silver salmon, chum are nonetheless an excellent source of protein and have enough oil to be versatile in cooking.

In fact, many believe that chum have a bad rap. At the least, chum are clearly better than farmed salmon. If caught in the ocean and processed well, chum can make a tasty, lightly-flavored dish. Chum’s roe (eggs) are also the most valuable of all the Pacific salmon, and they are often caught for the roe alone. These fish are also marketed as “silverbright.”

Trader Joe’s has rocketed from 15th to third place on Greenpeace’s 2013 sustainable seafood scorecard based largely on the retailer’s decision to sharply reduce its sale of red-listed items and establish tougher standards for the seafood it purchases, whether wild or farmed.

Just a few years ago, Greenpeace was in a pitched battle with the Monrovia, Calif.,-based specialty retailer, which it had labeled “Traitor Joe’s” because of its sale of red-listed seafood such as Chilean sea bass and orange roughy.  The environmental group dropped its campaign in 2010 after Trader Joe’s promised it would have a fully sustainable seafood department by 2013.  Seafood ends up on the red list for a variety of reasons, including poor stock health, by-catch issues or habitat destruction.

With its move into Greenpeace’s “green zone,” where it joins industry leaders Whole Foods and Safeway, Trader Joe’s has achieved the “biggest jump in the history of the report,” said Casson Trenor, Greenpeace senior markets campaigner.

“No doubt the performance of this seminal dark horse has left more than a few of its competitors blinking in amazement and choking on its dust,” stated Greenpeace’s seventh annual Carting Away the Oceans Report, released May 29, 2013.

Trader Joe’s is also taking a leading role in important industrywide initiatives such as the campaign to protect the Zhemchug and Pribilof Canyons of the Bering Sea, which are among the most diverse marine ecosystems in the world, according to Trenor. He said Trader Joe’s, Safeway, Wegmans and Supervalu have thrown their support behind development of a science-based plan for protecting the deep sea canyons, which are also home for a large Alaskan pollock fishing fleet.

Asked how the retailer felt about its positive report card, Trader Joe’s spokeswoman Alison Mochizuki said she could not comment on the seafood sustainability issue beyond a March 14, 2011, statement posted on the company website.

Report card: Trader Joe’s still has work to do

Though the overall news was positive, Trader Joe’s has not yet made good on its pledge to eliminate all unsustainable seafood items from its inventory by this year, according to Greenpeace. 

The report said Trader Joe’s was still selling at least four red-listed items: Alaska pollock, Atlantic salmon, Atlantic sea scallops and tropical shrimp. And, the report said, the retailer  still needs to do a lot better job of labeling its seafood so customers know what they’re buying and where it came from.

“The reality is they didn’t make good on their promise, but they sure did a lot of things well,” Trenor said, acknowledging mixed feelings about Trader Joe’s high marks given its continued red-list sales and lack of transparency. “In the end, we had to appraise it for the reality.”

Did “Traitor Joe’s” make a difference? “There’s no doubt that the Greenpeace-led campaign against Trader Joe’s to get them to change in 2009 and 2010 made them very uncomfortable,” Trenor said. “But at the end of the day, it was an outpouring of support from Trader Joe’s customers themselves that catalyzed this change within the company.”

Another piece of positive news tucked in the May 29 report: Wal-Mart has announced it will offer consumers canned skipjack tuna that has been caught without the use of fish-aggregating devices. The fish-aggregating device-free canned skipjack tuna will be sold under the Ocean Natural brand in more than 3,000 Wal-Mart stores across the U.S.

“Until this happened, American consumers operating on a budget had to make a choice between their wallet and protecting the planet,” Trenor said. “It’s a huge change.”

A Greenpeace protest at a Trader Joe's store. Credit: Greenpeace

I’m a Trader Joe’s groupie. So I was thrilled when my Hawaiian-shirt-clad friends announced that they would be purchasing all their seafood from sustainable sources by the end of 2012. The Monrovia, Calif.,-based retailer had been a target of a Greenpeace “Traitor Joe’s” campaign for its ocean-unfriendly policies, including the sale of a variety of endangered fish. With that pledge, Trader Joe’s joined the good guys.

But four months past the deadline, my glee has changed to frustration over Trader Joe’s unwillingness to say whether it has indeed gone sustainable. The retailer’s only statement on the subject, a customer update posted on its website March 27, does not address the deadline at all. Instead it lays out a number of steps it has taken in “support of our seafood goal of shifting to sustainable sources.”

Trader Joe’s says it will do the following: Stop selling swordfish caught in Southeast Asia, only sell canned yellowfin and albacore tuna caught using approved sustainable methods, set up new standards for suppliers of farmed shrimp and keep genetically engineered salmon off its shelves.  The store has also stopped selling endangered Chilean sea bass, orange roughy and red snapper. Those are all steps in the right direction. (May 30 update: Trader Joe’s, Greenpeace bury hatchet, sort of)

Trader Joe’s mum on meeting deadline

But can I go to Trader Joe’s today and pick up fish fillets for dinner without worrying about whether I am contributing to the degradation of the ocean?

Apparently not. When asked whether Trader Joe’s had met its December deadline, company spokeswoman Alison Mochizuki was mum. “Beyond the statement, there is nothing else we can say at this time,” she says.

Why the mystery? Everyone understands a missed deadline, particularly when it involves something as complex as seafood sustainability, global supply chains and the economics of food. But refusing to discuss the matter makes it look like Trader Joe’s is hiding something.

Casson Trenor, a senior seafood campaigner at Greenpeace, acknowledges Trader Joe’s is making “tremendous progress” toward saving the oceans. But he says the company’s reluctance to provide more information about its seafood sourcing policies has made it nearly impossible to determine whether the retailer is actually living up to its promises.

For example, he says the store is still selling items such as farmed salmon and dredged scallops that Greenpeace and other groups do not consider sustainable. Are they simply clearing out old inventory? Or are they flouting their own goals and hoping others won’t notice?

There are a lot of things to love about Trader Joe’s if you’re a foodie on a budget, a time-strapped cook (who knew broccoli slaw could taste so good?) or an aficionado of cheap wine. But unfortunately, transparency isn’t one of them. Trenor explains that a key part of Trader Joe’s success is its ability to create tasty, easy-to-use foods — such as spicy fish fillets — that aren’t available anywhere else. To prevent those products from being copied, the retailer has resisted pressure to reveal its sourcing or its suppliers.

“Trader Joe’s is all about magic and illusion,” Trenor says. “It delivers an experience that it doesn’t have to compete for because no one else can produce that product. Why would it give itself away?”

Verifying the sustainability of a seafood product requires two key pieces of information: where it was caught or farmed and how it was caught or farmed, explains Victoria Galitzine of FishWise, a Santa Cruz, Calif., organization working with the seafood industry to develop sustainable business practices. As a first step, she recommends checking out the Monterey Bay Aquarium’s Seafood Watch program, which has an app and pocket-sized cards with lists of ocean-friendly seafood and fish to avoid.

Trader Joe’s says it is in the process of enhancing its package labeling to include information on species’ Latin names; origin; and catch or production method. But until that happens, I will need to ask my friendly sales clerk whether that frozen yellowfin tuna from Fiji was caught using a long-line or purse seine equipped with a “fish aggregating device, or FAD.” If the answer is yes to the FAD, it’s on the red list and off my grill.

“Asking questions demonstrates to the retailers that its customers care about the environmental performance of its seafood and eventually those messages will trickle up the chain of command to the decision-makers who can affect significant change,” Galitzine says.

I can also support retailers who are clearly ocean-friendly. In mid-May, Greenpeace will publish its annual Seafood Sustainability Scorecard ranking grocery stores by their sustainable seafood practices. Last year, the top scores went to Safeway and Whole Foods while Trader Joe’s ranked 15 out of 20.

Trenor wouldn’t say whether Trader Joe’s will be getting a better grade this year. However, if Greenpeace finds a large gap between Trader Joe’s promises and its delivery, he is not ruling out a revival of its “Traitor Joe’s” campaign.

“Trader Joe’s did make a promise to Greenpeace and other groups and that’s why we suspended our campaign,” he says. “The time is up. The question now is did they actually do what they said they were going to do?”

A spoonful of Oona caviar. Credit: Tropenhaus Frutigen

Anyone who’s ever traveled in the Swiss Alps will know that farming there is nothing new. Wherever you go, you will see doe-eyed, moleskin-brown cows grazing vertiginous, brilliant green, manicured hillsides, their fragrant milk destined for great wheels of hard mountain cheese. But fish farming? It sounds unlikely — a bit like salmon farming in the Yemen — but it’s true.

The story began with the Lötschberg rail tunnel, which enters the Alps at Frutigen in the heart of the Bernese Oberland and emerges the other side at Raron in the Valais.

The tunnel is the latest example of the Swiss flair for engineering. As often happens when tunneling in the Alps, the project hit a few snags. Chief among these was the water runoff from rain and melting snow, which filters through the limestone layers to the tunnel below. Thanks to the geothermal effect, the water is warmed on its descent through the mountain to a rather comfortable 64 F. To channel it directly into the local river would have played havoc with the wild fish population, accustomed to an icy alpine torrent.

The solution came from engineer Peter Hufschmied, head of site management for the tunnel and a keen angler. Instead of expending energy in cooling down the water before allowing it to run off, why not take advantage of the warmth to raise fish? Simultaneously, they would use any surplus energy to heat greenhouses where tropical plants and fruits would grow. A perfect  – and perfectly sustainable — solution.

The Tropenhaus in Frutigen was born, a pilot project was put in place in 2002, and by 2005 the first sturgeon were introduced. The original Swiss caviar, christened Oona (a word with Celtic roots suggesting “unique” or “extraordinary”), was harvested in the winter of 2011-12. Now leading Swiss chefs such as Heiko Nieder at the Dolder Grand in Zürich, Werner Rothen of Restaurant Schöngrün at the Paul Klee Centre in Bern, and Ivo Adam of Restaurant Seven in Ascona on Lake Maggiore can’t get enough of it.

At least 27 different sturgeon species are raised or fished for caviar. From these, the Tropenhaus chose the Siberian sturgeon, Acipenser baerii. It’s a strange and wonderful beast, light gray to brown in color with five rows of bony plates along its back and sides; an elongated, upturned snout; and a kind of four-pronged goatee beard. In captivity, the females of the species will mature at approximately 6 years of age, which makes them an economic proposition for farming. (Wild Siberian sturgeon needs at least 20 years to reach maturity.)

Once mature, the females are stunned and killed, the sac of roe is lifted out and set aside and the fish is deftly filleted. The fillets — firm, dense and devoid of bones — feature on the menus of the two on-site Tropenhaus restaurants and are also sold to restaurants and shops (including select branches of the Swiss retailer Coop, which is also the Tropenhaus’ main shareholder). Some fillets are sold fresh, others are smoked to create a delicacy not unlike smoked eel.

Harvesting roe for caviar a simple process

Considering the mystique surrounding caviar, the process for making it seems simple, at least as demonstrated by caviar-meister Tobias Felix. Clad in a hairnet, overalls, a plastic apron and white boots and equipped with surgical mask and latex gloves, he looks like a cross between an astronaut and a surgeon.

First, taking care not to damage the precious eggs, he gently coaxes and massages them through a wire mesh, leaving behind the membrane that surrounds them. Next, he rinses the eggs in cold water, drains them in a fine-meshed sieve and painstakingly picks out impurities with tweezers. At this stage, the eggs are a dull grayish-black; only when he adds the carefully calculated measure of salt will they take on their characteristic glossy sheen. The newly salted caviar is promptly transferred into custom-made tins, which are sealed hermetically. The entire process takes 15 minutes from start to finish.

For the final step, the tin is embedded in a sleek, black sphere, which in turn is enclosed in a solid chunk of glass resembling an ice cube, made at the Hergiswil glass factory on Lace Lucerne, an ultra-chic piece of packaging that won a coveted Red Dot Design award in 2012.

The likelihood of Swiss caviar coming to a table anywhere near you is probably slim. “The quantities are tiny (production in the first year was around 300 kilograms, 700 pounds) and for the moment we are focusing just on Switzerland,” admits marketing manager Andreas Schmid. But there are ambitious plans afoot: Production is set to increase tenfold, and then they will consider the export market.

Even farmed, Swiss caviar will never be cheap; that’s at least part of its mystique. (Thirty grams or 1 ounce of Oona costs 144 Swiss francs, or $155 U.S.) But now that caviar from wild fish is out of bounds due to a disastrous combination of damming, overfishing, pollution and poaching, farmed caviar is increasingly meeting demand for this prized product. Sturgeon is already raised on fish farms all over the world, from France, Spain and Italy to Russia, China, Canada and the United States.

Now Switzerland has joined the ranks.

Where do chefs eat? As culinary professionals have become celebrities, their favorite haunts have attracted more attention. Want to know where Ludo Lefebvre gets his favorite pancakes?  Or where to find the best sushi, according to Danny Bowein (of Mission Chinese fame)? ChefsFeed has the answers, and a bit more. With thousands of high-end to hole-in-the-wall restaurant recommendations straight from the mouths of the country’s best chefs, you’ll learn where they love to go, and most important, what they like to order. There are currently 20 different cities on the app, with at least 20 chefs per city. The app is very user-friendly, with a little smiling face (usually) of the chef and photos of his or her recommended dishes. You can click on the dish and get details about the restaurant and also why the chef likes it. This has got to be one of the best ways to hunt down a meal. The icon is pretty cool, too.

Split the bill without pain

No, Splitsville is not an app that will supply you with text-message breakup lines. Rather, it is an app that will help you split a restaurant bill.  Sure, when there’s just two of you it’s easy —  excuse yourself to the restroom and hope the other person pays. But what to do if you have an odd number of people dining? Simply open up this little bad boy, enter the total amount (plus tip, of course) then enter the number of diners, and the app will do the rest. Of course, so will a calculator. Here’s the difference: If you arrived only in time for dessert whilst your friends feasted on steak and lobster, you will not have to pay for their surf and turf gluttony. Specify that your crème brûlée only cost you $15 and the app will adjust accordingly, charging your friends for their share while you pay for what you had. Never again will you feel cheated by a tab because your buddy ordered one more beer than you. It will be accounted for, and it will be fair — Splitsville will make sure of it.

Find sustainable fish choices

Seafood Watch has changed the way I buy fish. I refer to it for “ocean-friendly” advice every time I go out to buy seafood, especially at stores where I don’t have a friendly fishmonger to chat with. A bit of an admission as well: I sometimes purchase frozen seafood at Costco, and this app has kept me from many a fish-buying mistake. Made by the Monterey Bay Aquarium, the app brings you the most current recommendations for sustainable seafood and sushi, along with complete information about how each species should be fished or farmed. It is very simple to use and categorizes seafood as “best choice,” “good alternative” or “avoid,” with alternative options in the “avoid” section. When you delve into the app, you’ll notice the wealth of information available — everything from farming practices to where you can find a particular type of fish nearby. The sushi guide goes a bit further by providing the Japanese name as well as the English. This is an app worth downloading. All the information provided can also be found at www.seafoodwatch.org.

Drink wine by a biodynamic calendar

There is a growing opinion within the wine industry that wines taste better on certain days of the biodynamic calendar. Basically, with biodynamics, everything is dictated by the moon. The most common theory is, if the moon’s gravitational pull influences the ocean’s tide, it must also affect water in the soil and even sap within plants, which in turn can affect growth and flavor. There is a specific type of day depending on what phase the moon is in, they are: fruit, flower, leaf or root. For wine the best days to drink (and in fact transfer from tank to barrel) are said to be fruit and flower days. These days were originally used as guide for planting and sowing crops, but have more recently been extended into the wine world. Only a few blessed souls, however, have the ability to look at the moon and know what type of day it is. For the rest of us, there are two apps. BioGarden is a very cute biodynamic calendar app with little cartoon fruits and vegetables that tell you what type of day it is. You can scroll along from side to side quite easily and plan your biodynamic (drinking) calendar months in advance. When Wine Tastes Best is based off the biodynamic booklet of the same name. This is much more detailed, and actually tells you on the hour when the day type changes. It is set up a bit more seriously, and there is a free version that doesn’t allow you to look ahead in the week. Rest assured, neither app will ask you to bury your phone on the third full moon of the year.

Biogarden is $2.99 on iTunes
