Albacore (white) tuna tends to have more mercury in it than light tuna, and the FDA recommends eating up to 6 ounces of albacore tuna in a week. Fish usually low in mercury are salmon, canned light tuna, shrimp, pollock, and catfish. If you have no information about how much mercury might be in fish caught locally, the FDA recommends eating up to 6 ounces of that fish, but then do not eat any more fish that week.
