Aquaculture
History

The Gunditjmara, a local Aboriginal Australian people in south-western Victoria, Australia, may have raised short-finned eels as early as about 4,580 BCE. Evidence indicates they developed about 100 km (39 sq mi) of volcanic floodplains in the vicinity of Lake Condah into a complex of channels and dams, and used woven traps to capture eels, and to preserve them to eat all year round. The local Budj Bim Cultural Landscape, a World Heritage Site, is one of the oldest known aquaculture sites in the world.

Oral tradition in China tells of the culture of the common carp, Cyprinus carpio, as long ago as 2000–2100 BCE (around 4,000 years BP), but the earliest significant evidence lies in the literature, in the earliest monograph on fish culture called The Classic of Fish Culture, by Fan Li, written around 475 BCE (c. 2475 BP). Another ancient Chinese guide to aquaculture, wriiten by Yang Yu Jing around 460 BCE, shows that carp farming was becoming more sophisticated. The Jiahu site in China has circumstantial archeological evidence as possibly the oldest aquaculture locations, dating from 6200BCE (about 8,200 years BP), but this is speculative. When the waters subsided after river floods, some fish, mainly carp, were trapped in lakes. Early aquaculturists fed their brood using nymphs and silkworm faeces, and ate them.

Ancient Egyptians might have farmed fish (especially gilt-head bream) from Lake Bardawil about 1,500 BCE (about 3,500 BP), and they traded them with Canaan.

Gim cultivation is the oldest aquaculture in Korea. Early cultivation methods used bamboo or oak sticks; newer methods utilizing nets replaced them in the 19th century. Floating rafts have been used for mass production since the 1920s.

Japanese people cultivated seaweed by providing bamboo poles and, later, nets and oyster shells to serve as anchoring-surfaces for spores.

Romans bred fish in ponds and farmed oysters in coastal lagoons before 100 CE.

In medieval Europe, early Christian monasteries adopted Roman aquacultural practices. Aquaculture spread because people away from coasts and big rivers were otherwise dependant on fish which required salting in order to be preserved. Fish was an important food source in medieval Europe, when in average 150 days per year were days of fasting and abstinence, and meat was prohibited. Improvements in transportation during the 19th century made fresh fish easily available and inexpensive, even in inland areas, rendering aquaculture less popular. The 15th-century fishponds of the Trebon Basin in the present-day Czech Republic are maintained as a UNESCO World Heritage Site.

Samoans practised "a traditional form of giant clam ranching".

Hawaiians constructed oceanic fish ponds. A remarkable example is the "Menehune" fishpond dating from at least 1,000 years ago, at Alekoko. Legend records its construction by the mythical Menehune dwarf-people.

In the first half of the 18th century, German Stephan Ludwig Jacobi experimented with external fertilization of brown trout and salmon. He wrote an article " Von der künstlichen Erzeugung der Forellen und Lachse " (On the Artificial Production of Trout and Salmon) summarizing his findings, and earning him a reputation as the founder of artificial fish-rearing. By the latter decades of the 18th century, oyster-farming had begun in estuaries along the Atlantic Coast of North America.

The word "aquaculture" appeared in an 1855 newspaper article in reference to the harvesting of ice. It also appeared in descriptions of the terrestrial agricultural practise of sub-irrigation in the late-19th century before becoming associated primarily with the cultivation of aquatic plant- and animal-species. (The Oxford English Dictionary records the common modern usage of "aquaculture" from 1887; and that of "aquiculture" from 1867.)

In 1859, Stephen Ainsworth of West Bloomfield, New York, began experiments with brook trout. By 1864, Seth Green had established a commercial fish-hatching operation at Caledonia Springs, near Rochester, New York. By 1866, with the involvement of W. W. Fletcher of Concord, Massachusetts, artificial fish-hatcheries operated both in both Canada and in the United States. When the Dildo Island fish hatchery opened in Newfoundland in 1889, it was the largest and most advanced in the world. The word "aquaculture" was used in descriptions of the hatcheries experiments with cod and lobster in 1890.

By the 1920s, the American Fish Culture Company of Carolina, Rhode Island, founded in the 1870s, was one of the leading producers of trout. During the 1940s, they perfected the method of manipulating the day- and night-cycle of fish so that they could be artificially spawned year-round.

Californians harvested wild kelp and attempted to manage supply around 1900, later labeling it a wartime resource.
