So as my wife and I were doing some research in hopes of promoting a solid diet and healthier lifestyle (and because she is pregnant right now), here is the list of those saltwater fish species that could do more harm than good to you and your health if eaten out of moderation. Strong Angler Cameron Parsons with a nice king fish FDA warns children, pregnant women and lactating moms to NOT eat any king mackerel due to their very high mercury content.
Eliminating these fish species in your diet can definitely reduce your chances of getting exposed to the harmful effects of mercury and other existing contaminants. Whether fresh or canned, Albacore still has mercury levels that are almost three times higher than the smaller skip jack.
According to a CNN report, this type of fish has extremely high levels of metal mercury that can eventually cause coordination loss, blindness and even death, depending on the amount or portion ingested. Scientists believed that such increased mercury content was due to the accumulation of certain contaminants in their body as they eat lots of smaller fish.
“What we found for our 124 sharks that we sampled was that about one-third of them came in with mercury levels that were over the Food and Drug Administration’s action level of one part per million,” Robert Hunter, director of Mote Marine Laboratory’s Center for Shark Research in Sarasota, said in a statement. The cobra is a delicious saltwater fish that sadly can soak up a lot of mercury.
Strong Angler Tina Corrode with what’s left of her swordfish you like catching daytime or nighttime swordfish, you might want to be careful how much of it you eat. Strong Angler Cindy Dillard with an evening bluefishBluefish are fun to catch, will hit pretty much anything you drag through the water, and can really rip some line out on light tackle.
Although most people throw back jacks and refer to them as a “junk fish”, but for those of you that do eat them, be careful! Greater Amber jack South Atlantic grouper (i.e. gag, scamp, red and snowy) Tile fish (also called golden or white snapper) Banded Rudder fish.
NOTE: On February 8, 2006, technical changes were made to the data that was posted on January 19, 2006. The changes corrected data or more properly characterized the species of fish or shellfish sampled.
On October 6, 2014, technical changes were made to allow viewers to review the list in order of mercury levels and in alphabetical order by fish species. Red grouper is available year-round with peak catches in the Atlantic and Gulf of Mexico occurring during the summer and fall.
Red grouper flesh is white and lean with a notable lack of bones, and is very forgiving when cooked as it remains moist, firm, and has large flakes. Red grouper is considered the best tasting grouper with a distinct shellfish finish due to its diet.
Biology Red grouper grow slowly and can reach up to 50 inches in length and weigh up to 50 pounds. Red grouper are protogynous hermaphrodites, meaning they all begin life as a female and eventually some may transform into males.
Red grouper have large mouths with a slight under-bite, which allows them to eat their prey whole by dilating their gill covers and rapidly inhaling. Species Habitat Red grouper are found in the western Atlantic Ocean with ranges extending from Massachusetts through the Gulf of Mexico and south to Brazil.
This process provides habitat to other species such as spiny lobster, black grouper, red porgy, and vermilion snapper. Their grouper habitat utilization investigation looks at seasonal movement patterns in an attempt to improve populations and fishery management.
The If program allocates shares of the total commercial catch limit amongst individual fishers. Under the program, each fisher owns a share of the quota and can choose to fish it at anytime during the open season.
Strict commercial reporting requirements prevent fishers from harvesting more than their individual allocation. The Reef Fish FMP has been a success in allowing red grouper populations to bounce back from overfishing that had occurred on and off in the Gulf since the 1970s.
They are fairly long-lived and come together to spawn in large numbers, characteristics that make them vulnerable to fishing pressure. The Gulf of Mexico population in the was declared overfished in 2000 and then was rebuilt to target levels in 2007, according to the U.S. National Marine Fisheries Service.
The South Atlantic stock is no longer overfished, but a 2010 assessment showed it hasn’t been fully rebuilt. Grouper fisheries have high impacts on nontarget species, the Monterey Bay Aquarium reported.
Venting tools are also employed to make it easier for reef fish to survive when released. In the United States, red grouper management measures include permits, annual catch limits, fishing quotas, marine protected areas that are closed to fishing, seasonal closures, gear restrictions, minimum size limits, and data reporting requirements.
It is true that fish contain some amount of mercury level due to contamination on the ocean. Mercury itself can be a dangerous substance when you over eating it thus it is better for you to limit the fish amount consumption.
That’s why the bigger the predatory fish are the higher the mercury level inside them. Although the snapper contain moderate amount of mercury, but you still need to limit your consumption especially for pregnant women or breastfeeding and children.
Yes, we understand that omega-3 fatty acid which you can find in the fish is really important for pregnant women and breastfeeding plus the children. The omega-3 fatty acids are wonderful for the baby development during pregnancy and it also contributes healthy substances for women in breastfeeding.
But, these small numbers of group still need to limit their consumption of fish including red snapper and better avoid eating fish with high mercury level like shark, king mackerel, and swordfish. However, you can still eat red snapper not more than four times a week in moderate amount.
First thing first, there is always a big concern from the FDA about mercury level in many fish. The mercury will turn into methyl mercury, it is a neurotoxin which can be found in the fish in small amount.
However, when the mercury is in higher level, the methyl mercury can turn into harmful toxic which can give negative effect for body nervous system. In addition, because of the high mercury level, there are four types of fish that better to be avoided during pregnancy.
Fortunately, the red snapper only contain moderate amount of mercury level thus you can still eat the fish. The selenium and mercury will bind together and form new substances which hard for the body to absorb.
In fact, aside red snapper, there are still so many fish types which fine to be consumed due to the high level of selenium including salmon, shellfish, grouper, and many more. So, the health benefit of consuming red snapper is greater than the risk of mercury inside it.
South Atlantic Federal WatersExcellent, but large individuals may contain ciguatera toxin and elevated mercury levels. Epinephelus Gustavus Regulatory Remarks: This species is part of the shallow water grouper spawning season closure: January 1 through April 30, except for red grouper harvested in federal waters off the coasts of North Carolina and South Carolina, which remain closed until June 1. A descending device is required on board all vessels fishing for or possessing snapper and grouper species in federal waters of the South Atlantic.
The descending device must be readily available for use and attached to at least 16 ounces of weight and at least 60 feet of line. Spawning Season Closure: January 1 – April 30; Annual Shallow-water Grouper Spawning Season Closure January 1 through April 30, except red grouper in federal waters off the coasts of North Carolina and South Carolina, which remain closed until June 1.
Commercial fishermen are required to use hooking tools when fishing for snapper grouper species. A descending device is required on board all vessels fishing for or possessing snapper and grouper species in federal waters of the South Atlantic.
The descending device must be readily available for use and attached to at least 16 ounces of weight and at least 60 feet of line. The use of non-offset, non-stainless steel circle hooks is required for all species in the snapper grouper complex when using hook-and-line gear with natural baits in waters North of 28 degrees N. latitude.
This prohibition does not apply to fish harvested, landed, and sold prior to the quota being reached and held in cold storage by a dealer. List of low and high mercury concentration levels in fish species, includes chart of fish species safe and not safe for pregnant women and public consumption.
US government scientists tested fish in 291 streams around the country for mercury contamination. The U.S. FDA recommends eating 8 – 12 ounces of fish low in mercury per week.
Fish contain vital nutrients including omega 3 fatty acids, protein, vitamins, and minerals such as iron. These nutrients are essential, particularly for pregnant moms, as they foster healthy fetal, infant, and childhood development.
Mercury is defined as a chemical element with symbol Hg and atomic number 80. Symptoms typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination.
The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure. That is why larger, longer-living predators such as sharks and swordfish tend to have more of the toxin than smaller fish such as sardines, sole, and trout.
US government scientists tested fish in 291 streams around the country for mercury contamination. The presence of mercury in fish can be a particular health concern for women who are or may become pregnant, nursing mothers, and young children.
Mercury levels in the Northern Pacific Ocean have risen about 30 percent over the past 20 years and are expected to rise by 50 percent more by 2050 as industrial mercury emissions increase, according to a 2009 study led by researchers at the U.S. Geological Survey and Harvard University. When you eat seafood containing methyl mercury, more than 95 percent is absorbed, passing into your bloodstream.

Abstract: List of low and high mercury concentration levels in fish species, includes chart of fish species safe and not safe for pregnant women and public consumption. It’s incredibly important to get ample omega-3 fatty acids, and certain fish can serve as potent sources.
But due to issues like mining, sewage and fossil fuel emissions, heavy metals like mercury are winding up in the water and building up in our fish. Unfortunately, low-level mercury poisoning from contaminated seafood is a real threat and can lead to devastating effects on health.
In fact, the shift to eating more farmed fish like tilapia is leading to highly inflammatory diets, according to a 2008 study published in the Journal of the American Dietetic Association. Wake Forest University School of Medicine researchers say tilapia is one of the most widely consumed fish in America.
Sustaining high levels of inflammation in the body can worsen symptoms of autoimmune disorders and may be linked to chronic conditions like heart disease, cancer and diabetes. If you must eat this fish, avoid tilapia from China, where farming practices are particularly worrisome.
In 2014, Oceana, the largest ocean conservation group in the world, conducted an investigation using data from the National Marine Fisheries Service. They found that commercial fishermen in the U.S. throw about 2 billion pounds of “by catch” overboard each year.
According to the report, if you’ve eaten U.S. halibut, there’s a good chance it came from this damaging fishery. Without further protection and enforcement of existing efforts, we may forever lose one of the biggest, most interesting fishes in the world.
Now common on menus around the U.S., Chilean sea bass overfishing has left this species in serious trouble. Furthermore, harvesting the fish from Chile is also plagued by poor management and by catch problems.
Eel Monterey Bay Aquarium’s Seafood Watch places eel on the “Avoid” list on its sushi guide because it’s slow to mature and has been overfished in many parts of the world, bringing some populations to collapse. In the Delaware River, for instance, eels are an integral part of spreading mussel populations that serve as natural water filters.
Aside from the issues with overfishing, eels tend to readily absorb and store harmful chemicals and contaminants such as poly chlorinated biphenyls (PCs) and flame retardants. What’s more, studies show that farmed salmon is more likely to contain harmful contaminants like PCs, which are pollutants linked to insulin resistance, obesity, cancer and stroke.
In 2009, Italian researchers discovered that 4-hexylresorcinol, a food additive used to prevent discoloration in shrimp that could reduce sperm count in men and increase breast cancer risk in women. Shrimp farm ponds are also treated with harmful chemicals and pesticides such as malachite green, rote none and organic compounds, all of which can have detrimental effects on health.
Plus, an Associated Press investigation uncovered a slavery network in Thailand dedicated to peeling shrimp sold around the world. In 2007, Thailand alone exported about $1.24 billion to the United States, according to Food and Water Watch.
Although Alaskan king crab legs legally can only be called that if they’re harvested from Alaska, widespread mislabeling is the norm. Generally known as “slime head” within the scientific community, seafood marketers had other ideas for this fish and gave the species a more appetizing name.
Beyond that, the orange roughly is also known to have higher mercury levels, which can be dangerous if consumed in large amounts. But apart from that, most shark species, which are slow to mature and don’t have a lot of offspring, are severely depleted.
Often referred to as Hon Mauro on sushi menus, this simply means blue fin tuna, which should be avoided at all costs. A better sushi choice would be fatso/skip jack tuna caught through Pacific troll or pole and line methods only.
However, due to its high demand for sushi, fisheries managers are still allowing commercial fishing to target it. Sadly, blue fin tuna numbers are at just 2.6 percent of historic population levels.
Aside from the obvious population collapse and extinction threat, this is also a large predatory fish that harbors higher levels of mercury. In fact, the mercury in this fish is so high that the Environmental Defense Fund recommends women and children avoid it altogether.
That’s certainly the case with king mackerel, as the Food and Drug Administration warns women and children to outright avoid it. You may want to avoid Spanish mackerel, too, which has also been shown to harbor elevated mercury levels.
Luckily, Atlantic mackerel is high in omega-3s, low in mercury and is rated a top choice in terms of health and sustainability. In 2015, an investigation found that more than a third of 19 restaurants in Atlanta sold fantasies (also known as “Vietnamese catfish”) as grouper.
In addition to being rich in heart-healthy fats, salmon is a great source of protein, B vitamins, potassium and selenium. Atlantic mackerel This oily fish is also high in health omega-3 fatty acids, along with protein, niacin, selenium and vitamin B12.
Finding safer seafood can be challenging and requires you to consider many factors, including sustainability, nutritional value, mercury levels and the risk of contamination with pollutants, pesticides or harmful chemicals. Finally, when you do eat fish, opt for things like wild-caught Alaskan salmon, Pacific sardines and Atlantic mackerel.
Join today and experience primary care designed for real life, in-office and in-app. Fish are a lean, healthy source of protein–and the oily kinds, such as salmon, tuna, and sardines–deliver this heart- and brain-healthy omega-3 fats that you should also be getting in your diet.
Fortunately, Seafood Watch, the program run by the Monterey Bay Aquarium, has combined data from leading health organizations and environmental groups to come up with “Super Green: Best of the Best,” their list of seafood that’s good for you and good for the environment. These fish have much lower mercury and contaminant ratings and those caught in colder northern waters often have higher omega-3 counts.
The challenge: You need to do your homework to know how your fish was caught or look for the Marine Stewardship Council (MSC) blue eco label. This close monitoring, along with strict quotas and careful management of water quality, means Alaska’s wild-caught salmon are both healthier (they pack 1,210 mg of omega-3s per 3-ounce serving and carry few contaminants) and more sustainable than just about any other salmon fishery.
Farmed oysters are good for you (a 3-ounce serving contains over 300 mg of omega-3s and about a third of the recommended daily values of iron). One health caveat: Raw shellfish, especially those from warm waters, may contain bacteria that can cause illnesses.
The tiny, inexpensive sardine is making it onto many lists of superfoods and for good reason. In the US, rainbow trout are farmed primarily in freshwater ponds and “raceways” where they are more protected from contaminants and fed a fish meal diet that has been fine-tuned to conserve resources.
All other farmed salmon still falls on Monterey Bay Aquarium’s Seafood Watch “avoid” list for a few reasons. Coho, however, are raised in closed freshwater pens and require less feed, so the environmental impacts are reduced.
In December 2009, the World Wildlife Fund put the blue fin tuna on its “10 for 2010” list of threatened species, alongside the giant panda, tigers, and leather back turtles. Though environmental groups are advocating for protected status, the blue fin continues to command as much as $177,000 a fish.
Slow-growing and prized for its buttery meat, Chilean sea bass has been fished to near depletion in its native cold Antarctic waters. The methods used to catch them–trawlers and longlines–have also damaged the ocean floor and hooked albatross and other seabirds.
High mercury levels in these giant fish have caused EDF to issue a consumption advisory. Groupers can live to be 40 but only reproduce over a short amount of time, making them vulnerable to overfishing.
This strange fish resembles a catfish in that it has whiskers and is a bottom-dweller, but its light, fresh taste made it a staple for gourmets. The fish is recovering some after being depleted, but the trawlers that drag for it also threaten the habitat where it lives.
Like grouper, this fish lives a long life but is slow to reproduce, making it vulnerable to overfishing. As Seafood Watch puts it: “Orange roughly lives 100 years or more–so the fillet in your freezer might be from a fish older than your grandmother!” This also means it has high levels of mercury, causing EDF to issue a health advisory.
Farmed salmon are fed fish meal, given antibiotics to combat diseases and have levels of PCs high enough to rate a health advisory from EDF.
