They provide food for millions of people and fishermen enjoy catching them for sport.
Fish are also important in the balance of nature.
They eat plants and animals and, in turn, become food for plants and animals. This is called the food chain. The next step in the chain is a small fish, like a bay anchovy or a menhaden, which eats the small organisms. The next step is a larger fish like a spotted sea trout eats the smaller fish. The next link in the chain is the fisherman who catches the sea trout and eats him for dinner.
