You love going fishing on the weekends. You grew up going fishing with your father and now you love taking your own kids out to fish. You always pack a cooler with your catch to take home and fry up for dinner. You read somewhere that there might be mercury in fish and you’re wondering if it’s safe to keep eating the fish you catch.
This article will tell you everything you need to know about mercury in fish. You’ll learn which fish have the most mercury and how to avoid mercury poisoning.
So, does freshwater fish have mercury?
Yes, freshwater fish do have mercury. Mercury is found in most freshwater and saltwater fish, and larger, older fish tend to have more mercury than younger fish. Fish that eat other fish have the most mercury.
Let’s dig into it and see what secrets it holds.
What Are The Dangers Of Mercury In Fish?
Mercury is a naturally occurring heavy metal, and can build up in the bodies of fish in the form of methylmercury. This is a highly toxic form of mercury, and can cause health problems, especially for fetuses and young children. Pregnant women and small children should avoid eating fish that may be contaminated with mercury. Symptoms of mercury poisoning include hearing and vision changes, personality changes, memory problems, seizures, and paralysis. In severe cases, mercury poisoning can be fatal.
Freshwater fish are not typically as high in mercury as saltwater fish, but can still contain traces of the metal. For most people, the risk from mercury by eating freshwater fish is not a health concern. However, pregnant women and small children should still avoid eating fish that may be contaminated.

How Can I Tell If A Fish Has Mercury In It?
The best way to tell if a fish has mercury in it is to check for fish advisories in your area. Health Canada has identified certain fish as being of more concern when it comes to mercury contamination, and these include shark, orange roughy, swordfish, and tilefish. In general, larger fish and fish that are high on the food chain are more likely to contain higher levels of mercury.
If you are concerned about mercury exposure, the best thing to do is to limit your consumption of fish and shellfish, and to choose smaller, younger fish which are lower on the food chain. Checking for fish advisories in your area is the best way to determine which fish are safe to eat and which should be avoided.

What Are Some Common Sources Of Mercury In Fish?
Some of the most common sources of mercury in fish are larger fish species, dental amalgams, and industrial processing. Mercury is a neurotoxin that can adversely affect a baby’s developing brain, so it is important to be aware of the potential sources of mercury in fish before consuming it. Larger fish species tend to accumulate more mercury in their bodies because they live longer and eat smaller fish that may contain mercury. Dental amalgams are another common source of mercury exposure, as they often contain mercury vapor. Industrial processing can also release mercury into the environment, which can then end up in fish.

How Can I Avoid Mercury In Fish?
As mentioned in the blog post, most people are concerned about mercury in fish, but don’t realize that freshwater fish can also contain mercury. While the levels are usually lower than in saltwater fish, they can still be harmful if you consume too much.
There are a few things you can do to avoid mercury in fish:
– Choose lower-mercury fish and seafood, such as salmon, shrimp, and canned light tuna.
– Eat 8 to 12 ounces (two to three meals) a week of a variety of fish and shellfish that are lower in mercury.
– Avoid large, predatory fish. To reduce your exposure to mercury, don’t eat shark, swordfish, king mackerel or tilefish.
– Skip uncooked fish and shellfish.
– Check fish consumption advisories before eating any fish.

What Are The Symptoms Of Mercury Poisoning?
The symptoms of mercury poisoning can vary depending on the level of exposure and the amount of mercury in the body. However, some common symptoms include tremors, impaired vision and hearing, muscle weakness, and emotional changes. Mercury poisoning can be treated with chelation therapy, but it is important to get medical help if you think you have been exposed to too much mercury.

Is Freshwater Fish Lower In Mercury?
Freshwater fish do contain lower levels of mercury than saltwater fish, but they are still a potential source of mercury exposure. Mercury is a heavy metal that can accumulate in the food chain, and it is particularly harmful to the developing nervous system. Pregnant women and young children are advised to avoid fish that are high in mercury, including freshwater species like pike, walleye and bass.
What Freshwater Fish Has Mercury?
The freshwater fish most likely to contain harmful amounts of mercury are smallmouth bass, walleye, largemouth bass, lake trout and Northern pike. These fish tend to be at the top of the food chain in freshwater ecosystems, and as such, they tend to accumulate mercury in their bodies. Mercury is a neurotoxin that can cause a variety of health problems, including brain damage, so it is important to avoid eating fish that may be contaminated with it.
Can You Get Mercury Poisoning From Freshwater Fish?
Yes, you can get mercury poisoning from freshwater fish. Methylmercury is a highly toxic form of mercury that can remain in soil or water for decades. It can accumulate to very high levels in the tissues of freshwater fish, and when people eat these fish, they can be exposed to harmful levels of mercury. Mercury poisoning can cause a range of health problems, including neurological damage, heart problems, and kidney damage.
How Does Mercury Get Into Freshwater Fish?
Mercury can enter freshwater fish in a few different ways. First, mercury can be deposited directly into lakes and rivers from the atmosphere. Once in a lake or river, mercury is converted to methylmercury by bacteria and other processes. Fish absorb methylmercury from their food and from water as it passes over their gills. Methylmercury is a highly toxic form of mercury that can accumulate in fish tissue over time. When people eat contaminated fish, they can be exposed to mercury and suffer from health effects, such as neurological damage.
Why Does Fish Have Mercury?
Mercury is a highly-toxic chemical that bioaccumulates in seafood. Exposure to mercury – even in small amounts – can cause serious health problems.
What Are The Benefits Of Eating Low Mercury Fish?
The benefits of eating low mercury fish are many. Fish is a healthy dietary choice for women in their reproductive years, with health benefits for both mother and child. Fish provides key nutrients that support a child’s brain development. Eating fish can also provide other health benefits, such as reducing the risk of heart disease.
What Fish Is High In Mercury?
Some fish are high in mercury and should be avoided, especially by pregnant women and young children. These include swordfish, shark, king mackerel, and bigeye tuna. Eating a variety of fish that are lower in mercury is the best way to reduce your exposure to this element.
- What Are The Levels Of Mercury In Salmon?: The levels of mercury in salmon are low, which is good news for those who consume this fish regularly.
- What Are Mercury In Fish Side Effects?: The side effects of mercury in fish can be serious and include neurological problems, gastrointestinal issues, and immune system problems.
- What Are The Benefits Of Eating Low Mercury Fish During Pregnancy?: Eating low mercury fish during pregnancy has many benefits, including improving brain function in children, reducing the risk of preterm birth, and improving the quality of breast milk. Low mercury fish is also a good source of omega-3 fatty acids, which are important for fetal development.
- Is Cod High In Mercury?: Cod is a smaller fish and is relatively low in mercury. In general, a good rule of thumb when it comes to mercury content is to consider the size of the fish. Smaller fish such as salmon, scallops, sardines and cod are safer to eat in larger quantities, while larger, predators such as shark, swordfish and tilefish should be avoided or eaten only in moderation.
Final Word
So, does freshwater fish have mercury? The answer is a resounding yes! But it’s important to remember that not all fish are equal when it comes to mercury content. Larger, older fish tend to have more mercury than younger fish, and fish that eat other fish have the most mercury. So, when choosing which fish to eat, it’s important to consider these factors.
