Farmed Seafood: What’s Safe and Nutritious

By Mark Sisson
126 Comments

Learning about the various types of aquaculture setups is interesting and useful, but we’re ultimately interested in whether they can produce safe, nutritious, affordable seafood. Wild seafood can be pricey, unavailable, and of questionable merit or sustainability. Certain wild species are definitely worth pursuing – Alaskan salmon, sardines, herring, mackerel, to name a few – but there are environmental (overfishing, collateral damage to other important species, structural damage to the marine environment) and health (accumulation of heavy metals like lead and mercury, polychlorinated biphenyl/PCB, dioxin) issues that the conscious fish eater must stay abreast of. Healthy and safe farmed seafood, then, would be a welcome alternative, if it’s out there.

Okay. Let’s get down to it.

Which farmed seafood is safe to eat? Is there anything like grass-fed beef or pastured chicken available in scales or shells?

Shellfish

As a whole, farmed shellfish, when compared to wild shellfish, are very good bets for the simple fact that both lead very similar lives. Every marine shellfish, whether farmed or wild, spends its life in the ocean attached to something – rocks, a rope, a pillar, coral, the ocean floor. The only difference is that farmed shellfish are deliberately placed there by farmers, while wild shellfish are distributed by the hand of Poseidon (actually, the Nereids do all the work while he gets the credit, but such is the life of a sea nymph). Most importantly, they all use the same sea water. They all obtain their food by sifting through that same sea water. Farmers don’t have to provide food. They’re not scattering corn and soy across the water, because it would be a waste. Shellfish, you see, are filter feeders.

That brings me to the primary concern people have with shellfish, or mollusks. “Filter feeder” just sounds bad. When we hear the phrase, we think of physical filters, the type we use in everyday life, like an air filter in a car engine or a coffee filter. Physical filters accumulate the undesirable stuff and are either cleaned, tossed, or recycled. They certainly aren’t eaten. Well, shellfish aren’t physical filters. They process toxins. They render harmful compounds inert and expel them. It’s true that if they reside in waters rich in heavy metals and industrial contaminants (like PCB or dioxins), some of those metals and contaminants will show up in the meat, but that’s true for any sea creature. In fact, shellfish are some of the safest, least contaminated farmed seafood whenever they’re tested.

They’re also extremely nutritious. Shellfish are extremely rich in vitamins and minerals. Three measly ounces of raw Pacific oyster (the bulk of which are farmed) gets you over 100% of the RDA for zinc, copper, selenium, B12, and half of the RDA for iron. For every 1.5 g of omega-3 they provide, just 0.1 g of omega-6 comes along for the ride. Bay scallops are high in magnesium and selenium, clams are good for iron, copper, and selenium, abalone for selenium and magnesium, while the lowly sea snail gives massive amounts of magnesium (200 g of snail gives over 500 mg of magnesium; maybe they’re counting the shell?) and good amounts of selenium.

Lately, a favorite of mine has been the green-lipped mussel, shipped frozen from New Zealand. I initially got interested in this particular variety because of the research into green-lipped mussel extract as a canine arthritis treatment. Buddha isn’t arthritic, but I find this stuff fascinating. I’ve had some arthritis in the past, and it never hurts to cover all your bases ahead of time. Besides, mussels are delicious and nutritious. The NZ green-lipped mussel gets good marks from the Monterey Bay Aquarium Seafood Watch, owing to its farmers’ sustainable practices: attach young mussels to ropes, lower the ropes into the ocean, and let nature take its course. I was also surprised to see the amount of omega-3s in these things. According to one study, 100 g of them (flesh only, no shells, frozen) comes with 1.5 g of DHA, 1.26 g of EPA, and not even half a gram of omega-6 fats.

Farmed shellfish are safe and just as nutritious as wild. If you’re worried about contamination, check the source and do some research. Always buy still living shellfish (dedicated seafood markets or Asian grocers are great places to buy live shellfish) where you can. If frozen is available, check the label and avoid imports from China, where waters are more likely to be heavily polluted.

American Catfish

The channel catfish is a bottom feeder, which sounds bad but doesn’t have to be. They’re just rapacious eaters, or foodies, even – a bit like hogs. If you feed them garbage and raise them in polluted waters (like occurs in Chinese catfish farms – check your labels!), you can’t really blame the species.

Farmed catfish is far fattier than wild catfish while being lower in omega-3s, but catfish has never been prized for its omega-3 content. While farmed catfish does have more omega-6 than wild – about 1.5g for every 100 g fillet, compared to around 0.22 g – most of the “added” fat in farmed is monounsaturated (5.7 g/100 g) and saturated (2.5 g/100 g) (PDF). Not too bad, especially if you compare it to something like conventional skin-on chicken thigh, which gives you 4 g saturated fat, 6 g monounsaturated fat, and 3 g omega-6s for a 100 g serving. US catfish farmers may not be feeding their fish pristine, natural diets of bottom-dwelling crustaceans, insects, and small fish, instead opting for combinations of meat and bonemeal, bloodmeal, fishmeal, various seedmeals, corn, soy, wheat byproducts, and vitamin/mineral supplements, but catfish seem to turn out decent fatty-acid profiles despite the departure from ancestral tradition (PDF).

Toxin-wise, catfish farmed in the US are subject to strict standards and, according to a 2008 study, has very low levels of methyl-mercury and industrial contaminants like PCBs and dioxins. You may want to avoid the abdominal fat deposits on farmed catfish, however, as they contained somewhat elevated levels of dioxins. (PDF) Other studies have shown conflicting results when comparing toxins levels in wild-caught and farm-raised US catfish, with some showing similar toxin levels (PDF) and others showing big disparities in favor of farm-raised. Either way, the toxins involved are at low enough concentrations not to cause worry, and they “appear to be dropping” in recent years.

If you like catfish, eat American farm-raised. It’s known for being a pretty bland fish (well known for deep frying in cornmeal batter and as a vehicle for sauces), but if it’s on the menu and you feel like fish… why not?

Tank-Farmed Freshwater Coho Salmon

Yes, that’s right. There is a decent farmed salmon: coho salmon raised in freshwater tanks. It’s not as magnificent as ruby-red firm-fleshed wild Alaskan sockeye, but it is low in omega-6s, fairly high in omega-3s, gets a “Best Choice” rating and makes “The Super Green List” (good for the environment, low in PCB and mercury, high in omega-3s) from the Monterey Bay Aquarium Seafood Watch, and spends its life in carefully monitored freshwater tanks (as opposed to tightly packed coastal nets where metals and contaminants like dioxins and PCBs accumulate). The biggest health problems with farmed (Atlantic) salmon are the increased levels of omega-6 and the high levels of environmental and industrial contaminants. Freshwater farmed coho salmon avoids both. According to several sources, farmed coho salmon (and this is the regular, coastal farmed stuff, not the quality freshwater tank coho) sports a high omega-3:omega-6 ratio. A recent study (PDF) found that a 100 g portion of raw farmed coho contained 1.42 g omega-3 and just 0.46 g omega-6 (ratio of 3.1:1), compared to wild coho’s 0.9 g omega-3 and 0.06 g omega-6 (ratio of 14:1). The ratio is way different, sure, but does it really matter, given the paltry absolute amount of omega-6? If you look at the USDA database, 100 g of raw farmed coho has 1.3 g of omega-3 and 0.3 g omega-6. Any way you cut it, farmed coho is a good source of essential fatty acids, and I’d guess that freshwater tank-farmed coho salmon is just as good as conventionally farmed coho in that regard, if not better.

As of now, there are only a few freshwater, landlocked coho salmon farms in operation: Domsea Farms, out of Washington state, which sells coho to Whole Foods and other retailers under the SweetSpring label; and Swift Aquaculture, in British Columbia, which supplies upscale restaurants. More are surely coming, though, so be on the lookout for tank-raised (not coastal) coho in your area. You’ll still want to avoid other farmed salmon, of course.

US Rainbow Trout

Most rainbow trout eaten in the United States is also farmed there, and it’s one of the better choices. It may not be a sexy, exotic fish with intense flavors and high levels of omega-3s, but it’s a solid choice with a low environmental impact, minimal levels of contaminants, and a reasonable price. You can get it fresh pretty much anywhere and know, just by the “Farmed, USA” label, that it’s safe to eat.

More so than any other farmed fish I’ve come across, the fatty acid profile of farmed trout closely resembles that of wild trout. For example, a single 100 gram fillet of farmed rainbow trout has a gram of omega-3, 0.7 g of omega-6, 150% of the B12 RDA, and a decent amount of selenium. The same amount of wild trout is extremely similar nutritionally, with the main changes being 200 mg fewer omega-3s and 500 mg fewer omega-6s.

Farmed trout is very low in environmental contaminants. Methyl-mercury levels are well within the acceptable range (PDF). The same seems to hold true for Canadian trout, too.

US Barramundi

A tropical white fish, the barramundi is the “it” fish of the moment. It’s low in overall fat, offers about 840 mg of omega-3 per 5 ounce serving, requires less wild fishmeal than other carnivorous fish, is relatively free of contaminants, lives in freshwater tanks (at least in the United States) where it can’t affect wild ocean stocks, and Dr. Oz sings its praises (which almost makes me want to delete this section). Barramundi is okay, I guess, but it sounds rather uninteresting and bland. It’s also expensive, fetching over ten dollars a pound for frozen fillets at some markets.

Still skeptical? Listen to the barramundi evangelist talk about the fish on NPR for an unbiased perspective. No, but seriously – by all accounts, it’s a safe farmed seafood choice with nice levels of omega-3s, so give it a shot. Or, at least, don’t fear the barramundi.

American Crayfish

These are freshwater crustaceans and thus not seafood, but I spent many a summer catching them in New England, so I’m going to include them anyway. Crayfish are great, like tiny lobsters. Crayfish farming gets a clean bill from the Monterey Bay Aquarium, and I like that crayfish farming often means setting the little mudbugs loose in a rice paddy or pond to feed on the local flora and fauna, enrich the local habitat, and breed like mad. Farmers will sometimes supplement with feed pellets, but not always. Not a lot of meat on them, but if fully cooked they can be entirely consumed, shell and all. If you’re too squeamish to do that, you should definitely suck out the sweet contents of the head and eat the tail.

Look – if Trapper Arne’s awesome 1990s-era website says that “crayfish is good eating,” I’m not going to argue. Stay away from imported crayfish from Asia, though; stick to farmed crayfish from the United States.

What say you? Have I gone mad? Is all farmed seafood poisonous and toxic? Have I left out your favorites? Let me hear about it.

Tilapia is relatively benign in terms of enviro impact and farmed is ok in terms of eating. It’s got low levels of Omega 6, but it’s got low levels of Omega 3 (among the lowest among fish), but that’s because it’s very, very low in fat total. I eat it, but it’s kind of a blah fish with little flavor and little going for it nutritionally.

For anybody thinking about going entirely primal, wild crayfish should never be eaten raw or undercooked. You can get a particularly nasty parasitic worm (that causes paragonimiasis) if you do anything so silly!

In New England (Maine especially) and Maritime Canada we have a wonderful native shrimp available in December through ?…the season depends on the natural cycle, abundance and over fishing. This year the season was cut short by half…bummer. The shrimp are small but quite tasty, sweet.
And they are fresh, caught in the morning and for sale off a truck on the side of the road by evening. Some catch their own in traps..I don’t as I have no boat in the water during the season.

Thanks! That is really useful. I was surprised by both the catfish and the Barramundi. One question, though–is all farmed shrimp equally terrible? I usually avoid it, but if crayfish can be done sustainably, you’d expect there to be a clean shrimp farm out there somewhere.

Crayfish are apparently also very sensitive to contaminants in the water. Apparently the simple presence of crayfish is an indication of a healthy body of water.

Plus, they’re fun to catch. 🙂 You do need a lot, though.

Just realize that most, if not all, of the fish food is full of ingredients imported from China. A lot of the food itself is produced there, too. So, the fish who are given pellets might not have high levels of testable toxins, but may very well have tons of contamination. I used to work at a small aquaculture operation and I avoid farm raised fish for that reason. It pains me to do this because the fish are raised with great care and with concern for the environment, but until someone can offer proof that the food given to… Read more »

You really don’t have to do that. Unless you eat fish caught within a few miles of the reactors, there is no possible risk from eating seafood.

Great article, as always. Thanks Mark. Chuck, Talapia is heavily farmed and can only be raised in warmer climates. The fry (baby fish) are usually subjected to hormone treatment that will result in a sex change – make them all male, which grow faster and larger. This is a fish that is truly massed produced at a scale and conditions rivalling commercially raised chickens. On another side note – the US government recently approved the farming of genetically modified salmon! Salmon farms operate in areas that are subject to severe weather conditions and there is no guarantee that escapes can… Read more »

Hey everyone, for those of you that have questions about specific species, follow the link Mark has in the article – Monterey Bay Aquarium Seafood Watch. It’s good stuff…take a look.

An excellent post. It is always great to hear which foods may be worth avoiding.

However, I work with the Bering Sea crab fisheries and would like to point out that they are also “shellfish.”

While the species I work with live far to deep to be effectively farmed, there are shallow water crab species.

I have no idea if anyone farms crab. However,since crab are certainly not sessile filter feeders, but carnivorous scavengers, without more information, I would be wary if I saw any farmed crab for sale.

I am SOOOO glad Rainbow Trout was on the list! There is a local farm that raises grass fed cows, pigs, and lamb that also offers Rainbow Trout. We were trying to figure out if it was good since it’s “farmed” but I think this gives us the green light to go ahead and buy. =)

Hal
5 years 4 months ago

I think that ultimately you have to make your own decision. If it’s local, and you see the conditions and can talk to the farmers about what they’re using for feed, etc. and are good with it, you get to make the decision. That’s the great thing about using local farms.

We grow lovely farmed salmon in NZ, both in the sea and in the canals connecting the hydro lakes. Farmed mussels are also a huge industry here… we had a feed of live ones last night.

Remember, though, that salmon are carnivores and their food source in captivity draws heavily from rather inexpensive ($) krill caught in the Southern Pacific, in direct (and indirect) competion with fish, aquatic mammals and ocean going birds.

It would be devilishly hard to calculate, but every farmed salmon or trout you eat, will diminish the health of Southern Oceans. Our choice.

Unfortunately I am allergic to some such chemical used in farm-raising some fish and shrimp. Nastiness ensues. I stick to wild everything just to be safe. When I was a kid, I remember real catfish my dad caught as being the best fish ever. I bought some farm-raised a long time ago and it was really disappointing. And one more opinion: my husbands’ best friend has an issue with his neck (cartilage gone from between one vertabrae) and he swears his daily green lipped mussel supplement is what has helped the most for healing and pain relief.

From the OP:

“As a whole, farmed shellfish, when compared to wild shellfish, are very good bets for the simple fact that both lead very similar lives.”

“Farmed shellfish are safe and just as nutritious as wild. If you’re worried about contamination, check the source and do some research.”

I take this to mean that he’s including all shellfish in this blanket approval statement. Including shrimp.

Come on folks, pay attention.

I’m not sold on this ‘farmed catfish’ thing. Many American catfish farmers (on the east/gulf coast) feed them dumptrucks of dog food from purina.

You’d be wise to treat anything on mercola.com with great suspicion. It is a mixture of fact and fantasy.

“Restrutured steak” products must be labelled as such in the USA (see http://www.fsis.usda.gov/oppde/rdad/FRPubs/01-016DF.htm).

That article makes also several impossible claims (virus-sized fungi that infect plants and animals, ha!) and overall looks like pseudoscience and tabloid journalism.

As mentioned, the Monterey Bay Aquarium website has a great resource in deciding what seafood is environmentally healthy. It is not as simple as “this fish is good for the environment, this one is not” as generally it is the method of raising or catching the fish and the country of origin that makes the difference. My only complaint is sometimes it is impossible to find any info about where the seafood came from and how it is raised on the packaging…but I always check the Monterey Bay Aquarium listing before purchasing fish or other seafood now.

This post is very interesting indeed. I agree that the “farmed” bivalves are a good choice because they are grown in natural habitat eating the same things that the wild ones do. But the farm raised fin-fish are definitely questionable. The finfish are given soy, wheat, corn, supplements, etc… I’m not convinced that they are good. BUT, I know the wild stocks are in danger of being overfished. It’s truely are fine line we are walking. What to do?!

Hmmm. Interesting post Mark. I am feeling very eeek about wild fish myself lately due to concerns about contamination and I had previously thought the farm raised fish were perhaps not as nutritious but now I see that may not be true. I have read a few articles about the problems with pollution from fish farms being generated by all the fish poop as well as farmed fish who escape their pens wreaking havoc on the wild species. Eating sure is getting to be a complicated issue. A couple of people asked about shrimp, Food and Water Watch has done… Read more »

Traditionally, monks used to raise carp for food in ponds. I have heard that they don’t have a great taste, but it gets better if you put them in a separate fresh water tank without food for a few days to clear out their systems.

They have a vein that runs through their meat that the old timers around the Kaskaskia River in Illinois referred to as a “mud vein”. If you cut it out, carp is just like catfish: white, flaky and devoid of much flavor.

The nuisance fish gar are also edible, but they require a more nuanced method of cleaning, or they are too foul to stomach.
Basically, they also have the “mud vein” and they MUST be drained of ALL blood ASAP when cleaning them. Oven roasted, they are also quite tasty.

I do have a minor point of contention about your catfish description. The channel, blue and flathead catfish are most definitely NOT bottom feeders. They are predatory in the same way as the bass and perch family. They will occassionally scavenge for food if hungry, but by and large they eat live prey.

The varieties of bullheads (brown, black and yellow) are far more accurately described as bottom feeders.
