The FDA publishes a list of approved market names for food fish in The Seafood List: FDA Guide to Acceptable Market Names for Food Fish Sold in Inter-state Commerce 2002.

Adding confusion are the various colloquial names given to the same fish or the same name given to different fish in different localities. Identifying fish and shellfish properly can be difficult because of the vast number of similar- appearing fish and shellfish that are separate species within each family.

Fish such as cod and haddock contain very little fat and are referred to as lean fish. Fish containing a relatively large amount of fat, such as salmon and mackerel, are known as fatty or oily fish. However, the amount of fat a fish does contain affects the way it responds to cooking. (The orange color of salmon and some trout comes from pigments found in their food.) Compared to meats, fish do not contain large amounts of intermuscular fat. The absence of the oxygen-carrying protein myoglobin makes fish flesh very light or white in color. Fish, as well as most shellfish, are naturally tender, so the purpose of cooking is to firm proteins and enhance flavor. Fish flesh is composed of short muscle fibers separated by delicate sheets of connective tissue. The flesh of fish and shellfish consists primarily of water, protein, fat and minerals.
