Human uses of fish

People interact with fish in multiple ways, whether practically, in folklore and religion, or in art. They have economic importance in the fishing industry and fish farming; these industries provide some people with an income, and the general population with fish as food. Other practical uses of fish include recreational fishing and their use in biological research. Fish play symbolic roles in religion, mythology, folklore, and fairy tale, where stories about fish have been told in cultures around the world for thousands of years. Fish have similarly been depicted in art, literature, film, and music in many cultures. Academic study of fish in culture is called ethnoichthyology.
