There’s a phrase Mainers use when they really, really like something: “Wicked good,” they say. Right now they’re saying that about Maine sea scallops, harvested from the cold, clean waters in the state’s deep bays and around its widely scattered islands.
These are scallops from day-boat fishermen, who forage only inshore (within 3 miles of shore), leaving port before dawn and returning in the early afternoon with their 10- to 15-gallon allotment of fresh-shucked scallops. (A gallon of scallops weighs about 9 pounds.)

The season for these beauties just opened, and, with luck and a little help from Mother Nature, it will last through the winter, providing sweetly succulent seafood with a flavor and texture that put scallops high on a gourmet’s pinnacle. Unfortunately, they are also in short supply and the catch is tightly regulated. Maine sea scallops represent just about 1% to 1.5% of all the scallops consumed in the U.S. each year. Back in the 1980s, Maine fishermen harvested 4 million pounds of scallops annually, but that figure declined to an all-time low of just 33,000 pounds 10 years ago. Now, thanks to a combination of efforts from fishermen, along with the Penobscot East Resource Center, a prominent fisheries NGO, as well as the state’s Department of Marine Resources, the scallop population is being restored to sustainable levels, and a project is underway to give Maine sea scallops the same cachet as Maine lobster, a recognizable and sought-after treat for a festive winter table.
What makes Maine sea scallops so desirable is both their texture and flavor. That requires a brief lesson in physiology. The part of the scallop we consume is the adductor muscle, which connects the two shells of this bivalve. Most bivalves — clams, mussels and the like — are immobile, sitting in one place throughout their entire life cycle, patiently waiting for food to float by. But scallops are unusual in that they actually swim, clapping their shells together to propel themselves away from predators as their adductor muscle grows into a meaty chunk, as tender and tasty as filet mignon. As for the flavor, Maine sea scallops have a distinctive sweet nuttiness that experts say comes from the cold salt waters in which they thrive. Unlike scallops from other areas, they are as tasty raw as they are seared in a skillet or baked in a sea pie.
Moreover, because this is entirely a day-boat catch, the scallops arrive in port within hours of harvest and are usually shipped out within a short time frame, as fresh as a Maine morning. Deep sea scallop fishermen pack their catch in ice and frequently also in a solution of sodium tripolyphosphate. Scallops are like little sponges, absorbing moisture and, of course, increasing in weight. These deep sea scallops are sold — or they should be sold — as “wet” scallops, and they are to be avoided. If you try to sear off “wet”scallops, they exude a milky liquid into the frying pan and will never brown properly. Consumer alert: Even if you can’t find Maine sea scallops, you should only buy “dry” scallops, which have not had anything added to them.
Once you have the best-quality scallops in your kitchen, you should use them quickly, within a day or two. In Maine we often freeze scallops in order to prolong the season, but otherwise, we eat them raw (a squeeze of lime juice, a pinch of chopped green jalapeño and a little fresh cilantro will give them a delightful Mexican touch) or we cook them up in a variety of simple ways. Here is one, adapted from my “New Mediterranean Diet Cookbook.”
But first, a couple of tips in the kitchen:
- Be sure you get dry scallops.
- Remove and discard the thick, opaque bit attached like a strap to the side of the muscle — it’s tough.
- Dry the scallops thoroughly with paper towels before you start to cook.
- Don’t crowd the scallops when you sear them — they need plenty of room to brown perfectly.
Seared Maine Sea Scallops in a Tomato-Pepper Gratin
About 1/3 cup extra virgin olive oil, divided
1 cup yellow onion, finely chopped
2 garlic cloves, finally chopped
1 sweet red pepper, cored, seeded and slivered
4 to 6 canned plum tomatoes, drained and chopped (1 ½ cups)
1 tablespoon mild Spanish or Hungarian paprika
Sea salt and freshly ground black pepper to taste
1/2 to 3/4 cup dry white wine
1 1/2 pounds “dry” Maine sea scallops
1/4 to 1/2 cup instant flour (Wondra, for example)
1/4 cup chopped flat-leaf parsley
1/2 to 3/4 cup fine dry bread crumbs
- In a deep skillet, combine 2 tablespoons of olive oil with the onion and garlic and set over medium-low heat. As the vegetables start to sizzle and soften, lower the heat and stir in the pepper slivers.
- Stir to mix well and let cook until the pepper slivers are soft, then stir in the tomatoes, paprika, salt and pepper and let cook 4 to 5 minutes longer. If the vegetables start to stick to the pan, add a couple of tablespoons of wine to loosen them.
- When the vegetables are done and have reduced to a thick sauce, set aside. (These steps can be done well ahead.)
- When you’re ready to continue with the recipe, lay the scallops out on paper towels and pat dry on both surfaces. Turn on the broiler.
- Sprinkle the flour on a plate.
- Smear about half a tablespoon of oil over the bottom of a gratin dish or another type of shallow baking dish.
- Add 3 tablespoons of oil to another skillet and set over medium heat. When the oil is very hot, dip each scallop in the flour, dusting both sides lightly, then add to the hot oil. Sear on both sides until golden-brown, turning with tongs — about 2 minutes to a side.
- As the scallops finish cooking, remove each one to the oiled baking dish. (You may need to add more oil to the skillet before you finish with all the scallops.) Ideally you will cover the bottom of the dish with a single layer of scallops.
- When all the scallops are done, add 1/2 cup wine to the skillet and boil rapidly, scraping up any brown bits, then stir the tomato-pepper mixture into the wine and cook briefly, stirring to mix well.
- Spoon the hot sauce over the tops of the scallops, then top the sauce with a combination of chopped parsley and bread crumbs. Dribble a thread of olive oil over the top, using about 2 tablespoons of oil, no more.
- Transfer the dish to the broiler, keeping it 3 to 4 inches from the source of heat, and broil until the top is lightly browned and sizzling, about 5 to 7 minutes.
- Remove and serve immediately.

My husband and I spent our first year of marriage in Stockholm. As newlyweds we were deliriously happy, but as grad students we were broke. Our best entertainment consisted of visiting the city’s beautiful food hall, where we longingly eyed all the seafood we couldn’t afford. After a while, a kindly fishmonger named Tommy Henriksson took pity on us and introduced us to some local fish within our budget. Tommy taught us to make magic with fresh herring and cod — fish so inexpensive they were taken for granted. We learned how to pan-fry herring and to sear cod in a blazing hot cast-iron skillet with plenty of salt. It cooked up into beautiful, moist flakes.
But times have changed, and we can no longer take cod for granted. By 1994, the once-bounteous stock of cod in Georges Bank, a continental shelf off the coast of New England, had been depleted from overfishing. And although strict quotas were put into place, these protective measures came too late. Our native fish stocks still haven’t recovered.
The world’s largest population of native cod now swims in the Barents Sea, which washes the far northern coasts of Norway and Russia.
More from Zester Daily:
These cod are called skrei, from an Old Norse word meaning “to wander.” And wander they do. The skrei live for five years in the Barents’ nutrient-rich waters, where they acquire exceptional flavor. They then migrate to spawn in the Lofoten Islands, an archipelago off Norway’s northern coast.
Until the 1980s, when wet-fish and factory trawlers began to proliferate, small-boat fishing was the islanders’ lifeblood. They lived by the annual rhythms of the fisheries and revered all parts of the cod. By simmering the cod with its liver, roe and a little whey, they made a traditional one-pot meal called mølje. Besides adding depth of flavor, the liver’s high content of vitamin D kept people healthy during the dark, sun-starved winters.
The importance of cod
By Darra Goldstein
Ten Speed Press, 2015
Cod’s importance to the North dates from the earliest recorded times, both for its nutritional and commercial values. The Vikings were trading dried skrei by the 10th century. Today, the fish continues to be dried in various traditional ways, two of which are recognized by Slow Food’s Ark of Taste, an international effort to identify and catalog unique regional food items.
For tørrfisk (stockfish), the cod is line-caught, then quickly gutted and beheaded before being brought to shore. Two fish of similar size are bound together by their tails and draped on wooden racks to dry for two or three months in the salt air. Klippfisk (salt cod) is prepared farther south on Norway’s coast where large, flat rocks rise at the edge of the sea. The rocks are cleaned and spread with salt before split cod is laid out on them to dry into a delicacy that is less hard and brittle than tørrfisk. My personal favorite is boknafisk, cod that has been only partially dried in the salt air. When poached, its texture turns silken.
Population is threatened
The Barents fisheries have been generally well regulated. Norwegians recognize that a healthy population of cod also means rich populations of valuable groundfish like haddock and pollock. But this piscatorial treasure is now threatened. In 2010, after years of negotiation, Norway and Russia ratified the Barents Sea and Arctic Ocean Maritime Delimitation Treaty, which opened the waters to commercial interests.
The sea contains rich oil and natural gas deposits, and corporations on both sides of the border are eager to begin exploiting them. And although Norway is highly sensitive to environmental concerns, Russia is not. Pressure is increasing to drill for oil and gas in one of the last truly pristine places on earth.
Preservation is vital
Undamaged ecosystems are essential for fish to thrive. Unless carefully regulated, the oil and gas extraction industries will deplete the Barents Sea’s resources and then move on, leaving behind oil boom debris and polluted seabeds. The World Wildlife Fund expressed concern as far back as 2004, well before the international treaty was signed, over the potential loss of the Barents Sea habitat to overfishing and industrial development.
Because of the decline in the annual catch, the Lofotens are already less a working fishing community than a holiday destination. Rows of wooden drying racks now stand empty on some island beaches, like so many looming sculptures memorializing a once-crucial livelihood and tradition. Cod encapsulates the collective history of the Barents region and the Lofoten Islands. It is vital that we preserve the last healthy population of wild cod and protect these waters that nourish not only the body but the soul.

It began at 3 a.m., a bursting, loud, rumbling noise that broke the rural silence and my sleep. It came and went continuously. I couldn’t take it anymore and got up to investigate.
I was staying at a Japanese resort hotel next to Lake Saroma on the northeastern coast of the island of Hokkaido. Little did I know that the jarring racket in this usually quiet town would lead me to discover one of the most memorable meals of my trip and one of the area’s most lucrative food industries: scallop farming.
Scallop farming starts with a perfect lake
Lake Saroma, the third largest lake in Japan, is adjacent to the Sea of Okhotsk, separated from the sea by a narrow sand spit. It was once a freshwater lake. Every year in April and May, snow melt from the mountains gushed into the 13 rivers that empty into the lake and flooded the area. Aside from destroying homes and villages, it also ruined the livelihood of the fishermen. To prevent future floods, locals dug out a bit of the sand strip to create a channel.
The narrow passage not only let the freshwater out to ease flooding, it also allowed seawater to come in, especially during high tide, leaving much of the lake brackish.
The passage frequently closed because of moving sand during winter storms, and locals worked to reopen the channel every year. People soon discovered other advantages to keeping the passage open.
New fish come to the lake and scallops, too
Fishermen could now easily catch salmon, herring and ocean trout that swam into the lake. Scallops and oysters that thrive in brackish water also found a home. In the 1950s, Japan studied the idea of introducing scallop farming at the lake, and it has been very successful. Today the lake has two permanent, man-made concrete passages to the sea.
When I checked into the hotel the day before, I found a pair of binoculars in the room and admired the calm, silent lake and the sea beyond. The next morning I rubbed my drowsy eyes and tried to reconcile two very different experiences: the prior day’s calm with the early morning noise. Soon I saw the source of the racket: boats moving at high speed on the lake. I noticed that the boats raced out, stopped for a while and then raced back to shore. They looked as if they were competing. I quickly dressed and went to the reception desk to find out what was happening. “They are scallop farmers at Sakaeura Fishery,” I was told. Without having breakfast, I dashed to the fishing port about a mile from the hotel to get a firsthand look at the operation.
Fishermen work day and night bringing in scallops
Fishing boats were still coming in and leaving the port every few minutes. I approached a senior fisherman, Kuniyoshi Ooi, who seemed to be overseeing the operation. He told me that 90 fishermen in this port are licensed to farm scallops. Each fisherman has his own boat, and each employs an average of 10 part-time workers — students from a nearby university — at this busy time of the year. Students are attracted by the good pay, $25 dollars an hour for work from 3 a.m. to 8 a.m., Ooi said. The workers, dressed in bright colored uniforms, work as if part of a conveyor belt operation inside a long shed, extending several hundred feet along the quay.
Baby scallops are retrieved from the sacks
Scallop farming in Lake Saroma is a sustainable, environmentally friendly business. The first year of scallop culture begins in May when the fishermen drop a rope with a knitted sack to collect natural scallop larvae in the lake. Scallop larvae in nature affix themselves to the grass in water. In farming, it’s different. The larvae attach to the ropes lowered by the fishermen.
In August, fishermen remove the ropes with larvae from the water, transfer them to a larger, roughly knitted square sack and drop it into the water again. By the following May, the scallops in the sack have grown to about 2 inches. The boats retrieve the sacks, 200 at a time, with 1-year old scallops, called chigai.
Mostly students work on the scallop harvest
It was the roar of the boats engaged in this process that woke me from my deep sleep. The part-time workers removed the scallops from each sack, cleaned and sorted them, and transferred them into large, blue plastic bins. After unloading the sacks for processing at the dock, the boat again sped back onto the lake to fetch more.
No words were exchanged among the workers; each silently and rapidly did his job — on the boat, on the pier and in the shed. Neither did anyone show any interest in the visitor watching them and snapping iPhone photos so early in the morning. I learned that the year-old scallops are then transported through the channels to the sea and remain there to mature for 3 years before being harvested and sent to market.
Scallops go back to the sea for three more years
According to Ooi, the scallop harvest from the lake is about 44,000 tons each year. Fresh, frozen and dried scallops from this port not only satisfy the market in Japan but are exported to China, Hong Kong, Southeast Asia and the United States. The 90 fisherman are part of a cooperative that provides for all of their needs, including food and housing allowances, funds for boat upkeep and crews, and generous retirement benefits. Ooi said last year’s profit from the scallop harvest, after all expenses, was more than $250,000 for each member of the co-operative. Not a bad catch; these fishermen are not poor.
The sustainable side of scallop farming
In addition to their sustainable scallop farming operation, the Tokoro Fishery Association, of which the Sakaerura Fishery is a part, helps maintain the health of the local environment. In the past, cutting trees for opening the nearby land upstream from the lake for commercial development created problems at the fishery. Eroded sand and soil entered the lake and suffocated the fish. And the chemical contamination from the developed land degraded the water quality, which also affected the fishery.

The next day on my way north to Wakkanai, the northernmost city of Hokkaido, I stopped at a roadside restaurant to sample the “scallop ramen.” As I devoured the delicious dish, vivid memories of my early morning visit to the fishing port flashed back to my mind. No scallops ever tasted better than the ones in my ramen.

“Oysters are the canaries in the coal mine,” a fourth-generation oysterman once told me as we slogged across the mud flats of Willapa Bay in Washington. The grower was giving me a tour of his vast oyster beds that emerge as if by magic during every low tide. Oysters can filter up to 50 gallons of water per day, and the quality of the water they process affects their health … and their flavor. Healthy oysters mean a healthy environment, and when they struggle, they can indicate something dire for the habitat as a whole.
The oyster I swallowed had the precise taste of a clean, deep breath of Pacific Ocean air. It was what a gorgeous coastal landscape photo might taste like were it a flavor of ice cream. I understood why M.F.K. Fisher wrote that they were, “more like the smell of rock pools at low tide than any other food in the world,” and why that is a good thing. Then as I grew to understand that these creatures seemed specifically designed by nature, a benevolent creator or both for the task of pairing with splendid wines, I was hooked.
The only thing that remained was how to open the damn things. If you’re daunted by the process as I was, then this quick-start guide to oysters and wine will help you find, pair, unlock and swallow a magical taste of the marine environment, and then chase it with a sip of the best flavors that terrestrial geography has to offer.
Where to find oysters
You can find them at your local supermarket seafood counter. You buy them live, but given the complexity of unlocking them from their secure and encrusted boxes, how do you tell if they’re fresh and have been handled with care?
“Look for a place that sells fresh fish,” says Jaret Foster, chef/owner of Oyster Social, a pop-up mobile raw bar in Portland, Oregon. Look for a counter that sells fish that look and smell fresh, with no fishy odor or bruised flesh. Whole fish should have clear eyes and bright red or pink gills. If the owners take pride in their fish, then the odds are good they’re selling quality oysters.
Restaurants and seafood purveyors buy oysters in mesh bags that are marked with the date of harvest and the location. Ask to see the tag and snap a phone picture for reference. Like great wines, oysters taste like where they come from, so explore the regional differences. The Pacific Northwest, the Atlantic and Gulf are three broad domestic regions to check out, and there are dozens of locales nestled within these.
Finally, shells of fresh oysters should be sealed tight. No gaps or openings. A good proprietor won’t sell you oysters with open shells. If they’re difficult to open, you’re on the right track. This, of course, presents another problem that we’ll tackle later.
Gather the gear
If you’re serving oysters raw, you can do the work of opening them for your guests or share the fun. A good oyster knife is critical, but a screwdriver will work in a pinch (and the experience will drive you to find a good knife all the sooner). Crushed ice is important: From the moment you buy them at the market to when they’re waiting to be shucked and served, oysters should always be kept cool or on ice. Carry a small cooler bag to the market with you. Your vendor will provide the ice.
Mignonettes — fresh dressings — should be prepared in advanced and ready to roll. They can be as simple as lemon juice or your own creative dressing. A dish towel will help you hold the shell and protect your receiving hand from the dull knife blade. Work gloves on your receiving hand are an option to help you grip the shells, which can be both jagged and slippery.
Add a cutting board and a glass of wine and you’ll be geared up to swallow some sea.
A note on mignonettes
A good mignonette, a sauce or condiment for your oysters that is usually made fresh, can heighten the experience. I recommend avoiding jarred cocktail or hot sauces until you get a handle on the flavors of these slippery little critters as these sauces can overwhelm the freshness, but there’s no reason not to prepare some creative mignonettes. Recipes abound that feature rice wine vinegar, shallots, ginger, juniper, cucumbers, lime and more. A pair of options are included below.
Foster follows the rule of always eating the first oyster of the meal unadorned to experience its inherent flavor grounded in the region where it comes from.
And when it comes to oysters and wine, mignonettes are optional. In fact, a good wine sipped as a chaser can be considered a sort of mignonette in and of itself, and you may pick your wine style specifically for this task.
Find the right wine
If you’re eating the oysters unadorned, then a bracing Alsatian-style Riesling is hard to beat. The eye-watering brightness and acidity can act as a dressing. At a recent oyster workshop led by Oyster Social’s Foster, Jess Pierce of Brooks Winery presented the guests with a selection wines ranging from magnificent dry Rieslings to Pinot Gris and dry Muscadet.
“Oysters show their terroir well, so why not pair them with wines that do the same?” Pierce said as she poured wines framed by views of the vineyards where they were grown. More and more domestic producers are making Rieslings and Gewürztraminers in the dry, acidic Alsatian style, though they’re far from the only wine options.
Champagne and sparkling wines provide a lively way to begin any meal, and their acidity and effervescence complement the fresh earthy, tidal flavor of oysters. A transparent Chardonnay that really shows its minerality, like Chablis, is another great match. Laura Anderson, who runs Local Ocean Seafoods, known for its hyper-fresh menu and location directly across from the fishing fleet in Newport, Oregon, likes to pair half-oak, half-steel Chardonnays from Oregon’s Ribbon Ridge AVA: “I look for a crispness and minerality to balance with the wildness of the oysters,”she says.
The old saw is to drink white wines with shellfish, but there’s no need to limit yourself. Reds can work just fine. A light, slightly under-ripe Pinot Noir from a cool year in Oregon, New Zealand or Burgundy won’t break the bank and a bright, tart swallow is the perfect way to chase a glistening mollusk down your gullet.
Other reds to try include a cru Beaujolais or Gamay. Look for wines from places by the ocean, like Sicily,” Pierce says. Locals there drink their local reds and whites alike with menus largely driven by the sea.
Finally, it’s always good to look to the classics. M.F.K. Fisher claims that an Alsatian Pinot Blanc is the perfect wine match in her gorgeous treatise on bivalves, “Consider the Oyster.”
The art of the shuck
So you’ve got the gear, found your oysters and bought the wine: Now how do you unlock the things without slicing off a thumb or crushing the shell and spilling the flavor-infused liquor?
1. Wrap your passive hand in the dish towel. A glove will improve your grip. Oysters have a top and a bottom, so you want to hold the cup-side facing down.
2. Locate the hinge at the back of the shell if you can’t find a seam along the side. Insert your oyster knife into the hinge and twist like a key. It’ll take a try or three, but you should be able to create a gap and slowly work the two halves of the shell open by twisting the knife and working around the edges.
3. After pulling the top off, slide your knife along the roof of the top shell to cut the oyster’s adductor muscle.
4. Try not to spill the “liquor,” the silky juices inside the shell that pack much of the flavor. You’ll want to swallow that with the oyster.
5. Don’t worry about chips, cracks and bits of shell … you’ll make a mess, especially at first. Practice and plan to spend time tidying up. Study the process by hitting YouTube or state wildlife and extension offices in places where oysters are grown. They all offer plenty of advice to help get you started.
That’s pretty much everything you need to get started with oysters and wine. They’re both amazing natural products that have an unmatched ability to express flavors from where they are grown. Eating a clean, flavorful oyster is a small sort of tribute to ocean health. It is my hope that these tips lead you more quickly to your own oyster epiphany so that you aren’t required to pull on waders and slog after a spry oysterman through the drizzle … mud sucking at your boots until your hips and back ache, the stiff bay breeze whipping you … before you can appreciate the full glory of these tasty little bivalves and begin to care about where they come from.

As a seafood lover, writer and cook, I’ve lost track of the number of times people have asked me how to prepare delicate, flaky fish. This group includes the wildly popular tilapia, as well as flounder, sole and, my personal favorite, trout. Mild yet unusually complex in flavor and easy to cook, trout is the country’s oldest and most successful example of aquaculture. Rich in protein, vitamin B-12 and omega-3 fatty acids, it provides numerous delights with each bite.
A relative of salmon, trout ranges in color from silvery green to coppery brown and with orange-red, brown or black spots scattered over its skin. Influenced by diet and habitat, its delicate flesh runs from cream to red in color. In terms of size, it grows up to 50 pounds in the wild. Farm-raised trout weigh between 8 and 16 ounces.
Common trout species
Several species of trout exist. If you are or happen to know or are related to serious trout anglers, as I am, you may have access to brown and sea trout. Although the same species, brown trout reside in rivers while sea trout spend time in oceans. They both possess copper skin and pale pink flesh.

Then there is steelhead. Sometimes confused with salmon, this species has reddish flesh and a flavor reminiscent of salmon. Highly versatile, it can stand in for salmon in recipes. Classified as a sport fish, wild steelhead cannot be sold in markets. What you see in your fishmonger’s case or on restaurant menus is a product of aquaculture.
The most recognizable species may be the beautiful, multicolored rainbow trout. Adorned with a hot pink or coral stripe running from head to tail on both sides and a smattering of black spots, this striking fish ranges in body color from yellow to blue-green. When caught in the wild, rainbow trout have a pronounced nutty taste. The farm-raised version is milder in flavor and has creamy white to pink flesh.
Another name that may sound familiar is brook or speckled trout. Considered by many to be the best-tasting trout, this fish isn’t actually a trout. Instead it’s a type of char.
Tips for buying trout
At markets, trout is sold whole and as fillets. When shopping for this fish, you should look for shiny skin, bright eyes, moist flesh and a fresh, clean smell. Whole trout should have a layer of transparent slime over it; the more slime, the better and fresher the fish will be.
Whole trout tends to have more flavor than boned fillets. The only downside is that you may have to take out the tiny pin bones. However, you can always ask the fishmonger to do this for you.
Rainbow trout may be marketed as golden trout. Occasionally it gets mislabeled as steelhead. Just remember that steelhead has a bolder coloring than rainbow trout.
How to cook trout
When cooking trout, my go-to methods are pan searing, grilling or smoking. In the case of pan searing, I heat a smidgen of olive oil in a nonstick frying pan. Once the oil is hot, I place the fillets skin-side down in the pan. As soon as their edges turn ivory in color and flake when probed with a fork, about 2 to 3 minutes, I gently turn over the fish and allow the fillets to cook for another 2 to 3 minutes. That’s all it takes to pan sear trout.
A fast-cooking fish, trout also does well when baked, broiled, poached or steamed. No matter which cooking method I choose, I leave the skin on the trout. It will hold the meat together as the fish cooks.
Flavor pairings for trout
Trout’s nutty taste marries with myriad foods. Apples, carrots, celery, oranges, scallions, shallots and tomatoes partner well, as do mint, tarragon and thyme. It is also enlivened by a splash of cider, lemon juice or wine or a sprinkling of crumbled bacon or sliced olives. Almonds, pecans, pine nuts and walnuts make delicious coatings for this fish. Even so, I often prepare trout in a simple manner: With a mere sprinkle of salt and pepper and drizzle of olive oil or lemon juice, the fish will shine.
The Monterey Bay Aquarium’s Seafood Watch rates U.S. farm-raised rainbow trout as an “eco-best” seafood choice because it is raised in an environmentally sound manner. Low in mercury, it can be safely consumed at least four times per month.
Prep time: 5 minutes
Cook time: 6 minutes
Total time: 11 minutes
Yield: 4 servings
1 tablespoon olive oil
Sea salt, to taste
Ground black pepper, to taste
4 (6-ounce) trout fillets
Handful of Cerignola olives, roughly chopped
Extra virgin olive oil, to taste (optional)
1. Heat the olive oil in a nonstick pan over medium heat. As the oil is heating, season the trout fillets with salt and pepper.
2. Lay the trout skin-side down in the hot pan. Cook for 2 to 3 minutes, until the borders begin to turn ivory in color and the fish flakes when probed with a fork. Gently turn over the fillets and allow the fish to cook on the other side for 2 to 3 minutes.
3. Place the fillets on plates. Cover the tops with equal amounts of chopped olives. Drizzle extra virgin olive oil over the olives, if desired. Serve hot.

Back in the 1950s, it wasn’t unusual for fishermen plying the waters off Istanbul to land tuna weighing hundreds of pounds, or to have one of the massive fish leap out of the sea and over the prow of their boat. Dolphins cavorted alongside fishing vessels that hauled in lobster, oysters, razor clams, four kinds of crab and eight varieties of mussels.

Lüfer Bayramı celebrates the bluefish
Celebrated each October with fishing competitions, film screenings, children’s art activities, talks, and special meals, the holiday is named after one of Istanbul’s favorite fish, the fatty, flavorful — but now endangered — lüfer (bluefish). This Lüfer Bayramı grew out of a campaign the group launched in 2010 to get restaurants, fishmongers and consumers to stop buying, selling and eating juvenile lüfer that aren’t large enough to reproduce. (“Bayram” means “holiday” in Turkish.)
“I grew up in a fish-loving family. My father would grill lüfer on Saturdays, and we’d eat it with fish soup, pilaki [a bean dish], and vegetables cooked in olive oil,” Şenol says. “We weren’t rich, but fish was so cheap then that my father could buy lüfer in big batches at the early-morning fish auctions and give the extra to our neighbors.”
Prices of fish have gone up as stocks have diminished; data from the Food and Agriculture Organization of the United Nations indicate that the amount of bluefish caught in Turkey has plummeted over the past decade, from 25,000 tons in 2002 to just over 3,000 tons in 2011. Other research suggests that dozens of species have already disappeared from the Bosphorus Strait and Marmara Sea, two of the bodies of water on which Istanbul lies.
Both waterways are part of the lüfer’s annual migration route, a more than 1,000-mile-long journey that gives the fish its strong, distinctive taste, according to chef Şenol. “Bluefish in the United States, where I studied [at the French Culinary Institute in New York], is not the same,” she says. “Our lüfer travels from the Mediterranean up the Aegean to the Black Sea and back. It’s a route with different climates and salinities, and all that really affects its flavor.”
Lüfer season in Istanbul begins in the early fall, when the fish start their trip back down to more southern climes after spawning in the nutrient-rich waters of the Black Sea over the summer. Too many, though, are caught while still too small to breed and are sold, depending on their size, under the name çinekop or sarıkanat.
“People didn’t even realize these were all the same fish, but it’s really just like the difference between a sheep and a lamb,” says Koryürek. “Catching this fish so young eliminates the possibility of having more of them in the future.”
Campaign nets converts to the cause
A lobbying campaign led by Slow Food Istanbul along with Greenpeace Mediterranean has resulted in the raising of the minimum legal catch size for commercially fished lüfer from 14 centimeters to 20 centimeters (roughly 5.5 inches to almost 8 inches) — a good step, according to Koryürek, but an insufficient one. More than 100 restaurateurs like Şenol have agreed to not buy lüfer smaller than 24 centimeters (9 inches), the size activists say would be a more sustainable limit.
“We only have lüfer on the menu at Lokanta Maya for a very short period each year, when it is most plentiful,” says Şenol. She was one of a dozen top chefs in Istanbul who participated in this year’s Lüfer Bayramı by serving a special bluefish-based dish for a limited period of time.
“Since lüfer is a very fatty fish, it works best when grilled so it stays juicy inside as the skin gets crispy,” she explains. “It goes well with stronger flavors, so I paired small portions of the grilled fish with a salad of radishes, arugula, and red onions pickled with vinegar and just a little bit of sugar.”
Şenol and her staff also went out with fishermen to catch lüfer on the Bosphorus, an experience she says gave her a new appreciation for how hard the work is and how difficult it can be to keep from inadvertently landing some undersized fish even when using correctly sized nets.
Slow Food Istanbul has likewise been careful not to demonize local fishermen in its campaign, instead working to recruit them as allies.
“These waters have survived for hundreds of centuries with small-scale fishing,” says Koryürek. “But since the 1980s, the boats and nets have been getting bigger, the technology has changed, and the number of fishermen has gone up dramatically.” She estimates that large commercial boats are now catching 90% of Istanbul’s lüfer, and too often take advantage of lax enforcement of regulations by fishing too close to shore, in illegal amounts, or with methods that are environmentally damaging.
Istanbul’s soaring population over the past few decades — from less than 3 million in 1980 to more than 14 million today — poses a threefold threat to the city’s formerly robust fish stocks. The unchecked growth means increased competition among fishermen, greater consumer demand, and more heavily polluted water and highly urbanized coasts.
“Lüfer is a symbol of all we’ve lost and all we may lose,” says Koryürek. “These fish are a natural resource that is diminishing; protecting them needs to become a joint effort.”

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.
More from Zester Daily:
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.

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.”
