The amount of fish in a meal depends on your body weight. A person's weight is important, because body size affects how the body processes contaminants.

If you weigh 150-pounds, you could safely eat one-half pound/8 ounces of fish in a meal (precooked weight) to stay within the MDH fish consumption guidelines.

• To adjust the meal size for a lighter or heavier weight - subtract or add 1 ounce of fish for every 20 pounds of body weight. For example, one meal would be:
  
  7 ounces for a 130-pound person, and
  9 ounces for a 170-pound person.
  
  
• 8 ounces of uncooked fish is to equal about 6 ounces of cooked fish.
  
  
• One piece of sushi is about 1 ounce.
  

Spacing meals
Be sure to space out meals throughout the month.  For example, don't eat all of your fish meals for the entire month within a few days. Give your body time to handle the contaminants in-between fish meals.
