It is advisable not to eat mercury-rich fish such as these during pregnancy.. Look out for fish that taste especially metallic, a sign of high mercury levels. Medium-mercury fish include Chilean sea bass, grouper, cod, Mahi Mahi, monkfish, and snapper. Low-mercury fish are the safest for pregnant women.
