Oily fish are fish that contain at least 10% fat, most of which are the healthier omega-3 oils. In Australia, the oiliest fish include: canned salmon and sardines, some varieties of canned tuna, salmon, gemfish, blue-eye trevalla, blue mackerel, oysters and arrow squid.
The Dietary Guidelines for Americans states that to consume those higher amounts, children should only be fed fish from the “Best Choices” list that are even lower in mercury – these fish are anchovies, Atlantic mackerel, catfish, clams, crab, crawfish, flounder, haddock, mullet, oysters, plaice, pollock, salmon, ...
Choose fish and shellfish that are lower in mercury such as salmon, trout, tilapia, cod, sole, sardines, shrimp, oysters, and other shellfish. For the most health benefits, choose fatty fish such as salmon, trout, herring, chub mackerel, and sardines. o These fish have healthy omega-3 fatty acids.
Fish that contain high levels of mercury include shark, ray, swordfish, barramundi, gemfish, orange roughy, ling and southern bluefin tuna. Mercury is a naturally occurring element that is found in air, water and food.
You can also contact your local health department for information about local advisories. You need to check local advisories because some kinds of fish and shellfish caught in your local waters may have higher or much lower than average levels of mercury.
The traditional treatment for mercury poisoning is to stop all exposures. In many cases, chelation therapy is also used. This involves giving a medication (the chelator) which goes into the body and grabs the metal (chelos is the Greek word for claw) then carries the metal out of the body, usually into the urine.
White fish has at least as much protein as meat but much less fat. Good choices include King George whiting, flathead and snapper. Plus: It's official – all Australian fish species have now been analysed and every variety has enough omega-3s to be a 'good source'.
Packed with nutrients for a healthier you
With half the calories of salmon, Barramundi is still packed with Omega-3 fatty acids (known to promote both brain and cardiovascular health) and boasts 21 grams of lean protein in a four-ounce serving.
Actually, there is no such thing as a wild caught mercury free fish! All fish caught in their natural environment (wild caught) contain some level of toxin, including mercury. Now, this toxin level can vary due to first, the area of fishing and second, the species of fish.
Golden snapper is also known as white snapper or tilefish and has a mean mercury level of 1.45 which is too high to consume during pregnancy, and is probably best avoided (source: Perinatology).
Some seafood, however, can be dangerous for your growing baby. Certain fish – such as king mackerel, tilefish, swordfish, shark, albacore tuna and red snapper – contain large amounts of mercury that can be harmful to fetal brain and nervous system development.
Symptoms of organic mercury poisoning from long-term exposure include: Feeling numb or dull pain in certain parts of your body. Tremors (uncontrollable shaking). Unsteady walk.
Mercury and PFOS cannot be removed through cooking or cleaning -- they get into the flesh of the fish. You can reduce the amount of other contaminants like PCBs by removing fat when you clean and cook fish.
The FDA recommends eating 8 ounces of salmon per week. So you *can* eat it every day but in smaller servings. If you're pregnant, the FDA recommends eating 8 to 12 ounces of seafood per week from sources that have lower mercury levels — including salmon!
Worst: King Mackerel
But king mackerel -- especially ones caught in the Pacific Ocean -- are high in mercury. Doctors say young children and women who are pregnant or nursing should avoid them completely.
Eat low on the food chain.
Smaller fish—sardines, anchovies, farmed trout, fresh tilapia, arctic char—and bivalves such as scallops, clams, and oysters don't build up as many contaminants as do the large carnivores.
Healthy Heart and Brain
Our bodies don't produce omega-3 fatty acids so we must get them through the food we eat. Omega-3 fatty acids are found in every kind of fish, but are especially high in fatty fish. Some good choices are salmon, trout, sardines, herring, canned mackerel, canned light tuna, and oysters.
