What is the American national fish?

Because Americans come from such a wide range of various countries, there are many many different cultures co-existing. And because North and South America cover so many different bodies of water, the types of fish that Americans eat can be almost as many as actually exist in the world. But the Average American is mostly of German decent, and tends to eat Cod, Flounder, Salmon, Tilapia, Catfish, Haddock, Tuna, Crab, Lobster, shark, mahi mahi (simple minded dolphin). McDonalds uses a small simple white fish that is known for reproducing faster than it can ever possibly be consumed. But those are just the most commonly consumed. Americans find it taboo to eat fish that are higher level thinking, or intelligent. Because it's like eating a person. We don't eat Flipper like dolphins.

First, most Americans are not of German descent. Secondly, lobster, crab, and dolphins are not fish. But the other species mentioned above are eaten in great quantities by Americans.
