Im curious. I wont eat Seafood often but I will eat Seafood if I find it is safe to eat. Do Freshwater fish have a percentage of Mercury in them? or do all fish have mercury in them?

Yes, some fresh water does contain mercury, even Lake Tahoe has a tiny amount of naturally existing mercury.
Never eat farm raised fish, they do not have the resistance to mercury that wild fish do, and you should trim the darker colored bits between the skin and meat, that is the fat, and that is where mercury will be in the fish. Farm raised fish also have parasite problems and the pesticides that are used are not safe for the water, the fish, or humans.

Some fish do contains small amounts of mercury in them. I know in Lake Michigan it has be recommended not to eat the bigger lake trout because they contain quite a bit of mercury.

Big Macs are nasty anyways, 3-5 lbs. is perfect, any bigger and there's no guarantee on the quality of the meat, best to release or mount. My buddy caught an unofficial lake record and it was half rotten inside. Do you get lakers with red and white meat out there? We had both in Tahoe. It's the diet they have that does that I believe.

Yes why not, many rivers now have become dumping of industrial waste which aims profits. They deliberately throw waste without a waste treatment or waste water treatment plant are not eligible.
There must be mercury content that leach into the water and contaminate fish, plants and other organisms.

A nutrient powerhouse, seafood is not only safe to eat but should be consumed as part of a healthy diet. As a registered dietitian who counsels individuals and the fish industry, I understand your desire to ensure that your food is safe. Seafood provides many nutrients that are hard to come by in other food sources?such as omega-3 fatty acids and vitamin D?with no concern for mercury. In fact, the latest Dietary Guidelines for Americans states that ?the benefit of consuming seafood far outweigh the risks.? Americans should aim to eat a variety of seafood at least 2-3 times a week for its high omega-3 fatty acid content, which helps to reduce the risk of heart disease. For sport-caught fish, check your local advisories to ensure safety.
