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.

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.

U.S. wild-caught black grouper is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations. Fishing gears used to harvest black grouper have minimal impacts on habitat.

The groupers complex is not subject to overfishing based on 2019 catch data. Black grouper grow up to five feet long and can weigh up to 180 pounds.

Black grouper take advantage of other species’ reproductive aggregations for feeding. They are particularly associated with the southern Gulf of Mexico, Florida Keys, Cuba, the Bahamas, and throughout the Caribbean.

Annual catch limits are used for black grouper in the commercial and recreational fisheries. These fisheries are closed when their annual catch limit is projected to be met.

Both the commercial and recreational fisheries have size limits to reduce harvest of immature black grouper. The commercial and recreational fishing seasons are closed from January through April to protect black grouper during their peak spawning period.

Minimum size limits protect immature black grouper. Year-round and/or seasonal area closures for commercial and recreational sectors to protect spawning groupers.

Groupers are managed separately by commercial and recreational sector in Puerto Rico. Seasonal closure for black, red, tiger, yellow fin, and yellow edge groupers from February 1 through April 30.

And even though most freshwater and saltwater fish are generally considered safe to eat, there are some saltwater fish that contain varying levels of contaminants like mercury, PCs, and dioxins, which they acquire from the water they live in and from the food they eat. Though the amount of mercury in fish greatly varies depending on the type of fish, their size, weight, and age, it is still noteworthy to learn how these pollutants may pose potential health risks among us as consumers if we eat too much of it.

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. Because swordfish is up at the very top of the list in terms of mercury content for saltwater fish.

We’d love to hear from you… Let us know of any other saltwater fish high in mercury that we missed in the comment section. Grouper is available year-round with peak catches in the Atlantic and Gulf of Mexico occurring during the summer and fall.

Species Habitat Black grouper are found in the western Atlantic Ocean with ranges extending from Massachusetts to Brazil. They are particularly associated with the southern Gulf of Mexico, Florida Keys, Cuba, the Bahamas, and throughout the Caribbean.

Juveniles can occur in seagrass and oyster rubble habitat in the Carolina's, and along reefs in the Florida Keys and in Brazil. Adults prefer rocky bottoms, drop-off walls and ledges, caves, crevices, and coral and artificial reefs.

While they are relatively sedentary and can remain in one particular site for some time, black grouper move to progressively deeper waters as they age. They used passive acoustic recorders to monitor sound production indicative of spawning habitat use by groupers at Riley’s Hump in the Tortuga's South Ecological Reserve in Florida, the first known US spawning site for black grouper.

This study illustrated the importance of the Tortuga's South Ecological Reserve and called for continued research in order to understand its role in the recovery and sustainability of managed fish populations. Because of the vulnerability to overfishing associated with large aggregations and the biodiversity therein, it is important to consider spawning locations in the establishment of marine protected areas and seasonal closures.

Limiting the number of available permits (both transferable and nontransferable) available to commercial fishers; Establishing annual catch limits for both commercial and recreational fishers; Establishing overall species quotas; Commercial and recreational size limits to reduce harvest of immature grouper ; Seasonal closures to protect spawning aggregations; Gear restrictions to protect habitat and reduce by catch; and, Eight deep-water marine protected areas closed to fishing and possession of snapper and grouper. Established in 1984, the Reef Fish FMP and its amendments were designed to end historic overfishing for shallow water groupers and to rebuild populations.

Establishes and allocates annual species-specific catch limits between commercial and recreational fishers for groupers and tile fish; Sets gear restrictions; Sets minimum size restrictions to protect immature grouper ; and, Establishes year round and seasonal area closures for both commercial and recreational fishers to protect spawning stock and essential fish habitat. 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.

Red and black grouper are among the most important species caught in Mexico in terms of volume and economic value. Most grouper, particularly those caught in the Mexican industrial bottom longline fishery, is imported to the US.

Numerous entities are involved to some degree with creating, implementing, and enforcing fishery management strategies in Mexico. Under SAGA RPA, the National Aquaculture and Fishing Commission (Coalesce) is charged with developing and carrying out fisheries management regulations.

Wild Black grouper are found in the Atlantic from Massachusetts to Brazil, including the Gulf of Mexico. Unlike red grouper, black grouper in the United States is considered to be one stock across both the South Atlantic and Gulf of Mexico regions.

Grouper in generally are fairly long-lived and come together to spawn in large numbers, characteristics that make them vulnerable to fishing pressure. A May 2014 Seafood Watch report stated that according to the most recent stock assessment in 2010, black grouper is not considered overfished.

Grouper fisheries have high impacts on nontarget species, the Monterey Bay Aquarium reported. The black grouper fisheries use hooking devices and circle hooks to reduce by catch.

Venting tools are also employed to make it easier for reef fish to survive when released. 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.
