consists of the social behaviour and norms found in human societies and transmitted through social learning. Cultural universals in all human societies include expressive forms like art, music, dance, ritual, religion, and technologies like tool usage, cooking, shelter, and clothing. The concept of material culture covers physical expressions such as technology, architecture and art, whereas immaterial culture includes principles of social organization, mythology, philosophy, literature, and science. This article describes the roles played by fish in human culture, so defined.
For food
Throughout history, humans have utilized fish as a food source. Historically and today, most fish protein has come by means of catching wild fish. However, fish farming, which has been practiced since about 3,500 BC in China, is becoming increasingly important in many nations, and by 2016, more than 50% of the seafood brought to market was produced by aquaculture. Overall, about one-sixth of the world's protein is estimated to be provided by fish. Fisheries provide income for millions of people.
In recreation
Fish have been recognized as a source of beauty for almost as long as used for food, appearing in cave art, being raised as ornamental fish in ponds, and displayed in aquariums in homes, offices, or public settings. Some smaller and more colourful species, and sometimes painted fish, serve as ornamental fish in ponds and aquariums, and as pets. Angling is fishing for pleasure or competition, with a rod, reel, line, hooks and bait. It has been practised for centuries, providing pleasure and employment.
In science
and zebrafish are used as research models for studies in genetics and developmental biology. The zebrafish is the most commonly used laboratory vertebrate, offering the advantages of similar genetics to mammals, small size, simple environmental needs, transparent larvae permitting non-invasive imaging, plentiful offspring, rapid growth, and the ability to absorb mutagens added to their water.
In literature and film
Fish feature prominently in literature and film, as in books such as The Old Man and the Sea. Large fish, particularly sharks, have frequently been the subject of horror films and thrillers, most notably the novel Jaws, which spawned a series of films of the same name. Piranhas are shown in a similar light to sharks in films such as Piranha.
Fish themes have symbolic significance in many cultures and religions. In-and-Out Fish Design is a constant theme in the prehistoric and historical art of Iran, which demonstrates two swinging fishes named Kar-Mahi. Ahura Mazda sets these fishes on guard of roots of the tree of life, named Gukaran, so they are eternal sentries of worldly life, in Persian culture. In ancient Mesopotamia, fish offerings were made to the gods from the very earliest times. Fish were also a major symbol of Enki, the god of water. Fish frequently appear as a filling motif on cylinder seals from the Old Babylonian, usually in close proximity to malevolent forces, such as demons. Neo-Assyrian cylinder seals sometimes show fish resting on tables, which may be altars. The Assyrian King Sennacherib is recorded as having thrown a golden fish into the sea along with another golden object to accompany an offering of a golden boat to Ea. Starting during the Kassite Period, healers and exorcists dressed in ritual garb resembling the bodies of fish. This continued until the early Persian Period. During the Seleucid Period, the legendary Babylonian culture heroOannes, described by Berossus, was said to have dressed in the skin of a fish. Fish were sacred to the Syrian goddess Atargatis and, during her festivals, only her priests were permitted to eat them. In the Book of Jonah, a work of Jewish literature probably written in the fourth century BC, the central figure, a prophet named Jonah, is swallowed by a giant fish after being thrown overboard by the crew of the ship he is travelling on. The fish later vomits Jonah out on shore after three days. This book was later included as part of the Hebrew Bible, or Christian Old Testament, and a version of the story it contains is summarized in Surah 37:139-148 of the Quran. Early Christians used the ichthys, a symbol of a fish, to represent Jesus, because the Greek word for fish, ΙΧΘΥΣ, could be used as an acronym for "Ίησοῦς Χριστός, Θεοῦ Υἱός, Σωτήρ", meaning "Jesus Christ, Son of God, Saviour". In the dhamma of Buddhism the fish symbolize happiness as they have complete freedom of movement in the water. Often drawn in the form of carp which are regarded in the Orient as sacred on account of their elegant beauty, size and life-span. Among the deities said to take the form of a fish are Ika-Roa of the Polynesians, Dagon of various ancient Semitic peoples, the shark-gods of Hawaii and Matsya of the Hindus. Legends of half-human, half-fish mermaids are common in folklore, retold in the stories of Hans Christian Andersen. In British folk tales, mermaids both predict and bring ill fortune. The astrological symbolPisces is based on a constellation of the same name, but there is a second fish constellation in the night sky, Piscis Austrinus.
In art
Fish have been frequent subjects in art, reflecting their economic importance, for at least 14,000 years. They were commonly worked into patterns in Ancient Egypt, acquiring mythological significance in Ancient Greece and Rome, and from there into Christianity as a religious symbol; artists in China and Japan similarly use fish images symbolically. Teleosts became common in Renaissance art, with still life paintings reaching a peak of popularity in the Netherlands in the 17th century. In the 20th century, different artists such as Klee, Magritte, Matisse and Picasso used representations of teleosts to express radically different themes, from attractive to violent. The zoologist and artist Ernst Haeckel painted teleosts and other animals in his 1904 Kunstformen der Natur. Haeckel had become convinced by Goethe and Alexander von Humboldt that making accurate depictions of unfamiliar natural forms, such as from the deep oceans, he could not only discover "the laws of their origin and evolution but also to press into the secret parts of their beauty by sketching and painting".
