If you're wondering how much fish to serve, a two to three ounce portion of cooked fish provides an adequate amount of protein for one serving. However, many people prefer a somewhat larger portion.
Whole fish refers to fish just as it comes from the water.
The fish must be scaled or skinned and the entrails must be removed. The head, tail and fin can also be removed if desired. Drawn fish are whole fish with only the entrails removed. Dressed fish is commonly sold at fish markets. The fish is scaled, then the entrails and usually the tail, head and fins are removed.
