For reference, a meal is generally considered to be a 3 to 4 ounce cooked portion of fish or shellfish.

  • A 3 ounce portion of boneless fish or shellfish meat is about the size of a deck of cards.
  • A small can of drained tuna is approximately 3 to 4 ounces.
  • A salmon steak about 4 to 6 ounces.
  • The number of shrimp for a 3 to 4 ounce portion will vary depending on their size or the number per pound. If there are about 20 shrimp per pound, then a 3 to 4 ounce portion would be about 4 cooked shrimp, 6 cooked shrimp at 30 per pound, or 8 cooked shrimp at 40 per pound.
