Farmed freshwater fish such as catfish, barramundi, and trout and bivalves such as oysters and clams are some of the most important sources of nutrition for people in developing countries. States, the average daily intake of fish and shellfish is less than one-third of the recommended daily allowance (RDA) for protein.
RDA for fish is 0.8 g protein per kilogram of body weight per day for men and 1.2 g for women, based on the body mass index (BMI) of 25 to 29.9 kg/m(2). U.S.

Is it safe to eat any fish?
Eat up to 12 ounces (two average meals) a week of a variety of fish and shellfish that are lower in mercury. Low-mercury fish include shrimp, canned light tuna, salmon, pollock, and catfish. White tuna has more mercury than canned light tuna.
Limit your intake of albacore tuna to once or twice a month. If you are pregnant, talk to your health care provider about the best way to reduce your exposure to mercury during pregnancy.
What fish is lowest in mercury?
Children should only be fed fish from the “best choices” list that are lower in mercury, according to the Dietary Guidelines for Americans. In addition, the FDA recommends that children under the age of 6 months should not be given any fish at all.
This is because of the high levels of mercury that can be found in these foods. FDA also advises that pregnant women and women of childbearing age should limit their consumption of fish to no more than two servings per week.
What is the most toxic fish?
Pufferfish (some species are also called toadfish) have been given the title ‘Most Poisonous Fish’ and have also been labeled the second most poisonous vertebrate in the world. The neurotoxin produced by the stomachs of the puffer fish is what makes this fish so high in the danger zone.
This toxin is known to cause a wide range of symptoms in humans, including nausea, vomiting, diarrhea, abdominal pain, dizziness, weakness, and even death. (Carcharhinus carcharias) is the most venomous fish on the planet. It is capable of killing an adult human with a single bite. In fact, black snappers are the only species of fish that can kill a human in one bite!
The venom of this species is so potent that it has been used as an antivenom for the treatment of a variety of diseases, such as rabies, envenomation from snakebites, as well as as a painkiller and an anti-seizure agent. However, it is not known if this venom has any effect on humans.
Why you shouldn’t eat tilapia?
This toxic chemical has been known to cause inflammation and weaken the immune system. It can increase the risk for asthma and allergies. Dioxin, a toxic chemical in tilapia, has been linked to cancer and birth defects in humans. Tilapias are not the only fish to be affected by toxic chemicals.
States alone, the Environmental Protection Agency (EPA) estimates that more than 1,000 chemicals are used in the production of fish, shellfish, and other seafood. These chemicals include pesticides, herbicides, heavy metals, flame retardants, dyes, perfluorooctanoic acid (PFOA), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). In addition, some of these chemicals have been shown to have adverse effects on human health and the environment.
PCBs are known carcinogens that can cause liver and kidney damage, as well as reproductive and developmental problems in children and fetuses.
Is tilapia the dirtiest fish?
It is lower in mercury than other popular fishes due to its diet and place in the hierarchy of the aquatic environment. It’s also a good source of omega-3 fatty acids, which have been shown to reduce the risk of heart disease, cancer, and Alzheimer’s disease.
It’s a great choice for vegetarians and vegans, too, as it’s low in fat and high in protein, making it ideal for those who don’t want to eat meat or fish at all.
Which fish has the most mercury?
Larger and longer-lived fish tend to have the most mercury. These include shark, swordfish, fresh tuna, marlin, king mackerel, tilefish from the Gulf of Mexico, and northern pike. Smaller fish with small amounts of mercury in their tissues are more likely to be eaten by larger fish.
Mercury is a naturally occurring element that occurs naturally in the earth’s crust and in seawater ( 1 ). It is also a byproduct of the breakdown of organic matter ( 2 ).
