Fish = poison?

For those of you (like me) who are fans of fish for dinner, you may not have been very happy to hear the news of high levels of mercury in commercially sold fish (thanks to our water pollution). As it turns out, it's okay to eat fish as long as you eat the right kind at the right quantities. I was talking to a friend who is doing his PhD research in mercury removal from wetlands about what type of fish he would recommend. He recommended Tilapia, which he said not only has low mercury levels, but also has less impact on the environment because they are generally tank farmed (versus commercial fishing operations that make a mess of our natural waters). I decided to check up on what he said, and I found this website from the FDA that gives a list of the mercury levels found in fish. In general, you want to stay away from shark and swordfish, except on very rare occasions (these fish live longer, so there is more time for mercury to bioaccumulate). Salmon and tuna is okay, but you shouldn't eat it too often. Tilapia seems to be the best way to go, so that’s what I recommend. Here is a website with some tilapia recipes :-).
