A Word of Caution on Mercury
While it is recommended to eat one to two fish meals a week, it is wise to avoid fish high in mercury. Excess mercury appears to affect the nervous system, causing: numb or tingling fingers, lips and toes; developmental delays in walking and talking in children; muscle and joint pain; increased risk of heart attack.
Fish high in mercury include shark, swordfish (broadbill) and marlin, ray, gem fish, ling, orange roughy (sea perch) and southern blue fin tuna. Pregnant women, nursing mothers, women planning pregnancy and children up to six years old should avoid these fish.
If catching and eating your own fish, don't fish in polluted waters. Bottom feeder species, such as catfish, may ingest more pollutants.
