Before contact with Europeans, the Hawaiian people practiced aquaculture through development of fish ponds (Hawaiian: loko iʻa), the most advanced fish-husbandry among the original peoples of the Pacific. While other cultures in places like Egypt and China also used the practice, Hawaii's aquaculture was very advanced considering the much smaller size of the area of Hawaii compared to other aquacultural societies.[1] Hawaiian fishponds were typically shallow areas of a reef flat surrounded by a low lava rock wall (loko kuapa) built out from the shore. Several species of edible fish (such as mullet) thrive in such ponds, and Hawaiians developed methods to make them easy to catch.
"The full-scale development of loko i‘a (fishponds) from mauka (the mountains) to makai (the ocean) dates back over half a millennium. Cultivation and propagation centered on many different fresh and salt-water plants and animals, with the primary species being the prized ‘ama‘ama (mullet) and ‘awa (milkfish). An inventory in the early 1900s found 360 loko i‘a in the islands and identified 99 active ponds with an estimated annual production total of about 680,000 pounds, including 486,000 pounds of ‘ama‘ama and 194,000 pounds of ‘awa. Loko i‘a were extensive operating systems that produced an average of 400–600 pounds per acre per year, a significant amount considering the minimal amount of fishpond 'input' and maintenance effort apparent by that time."

The Hawaiian fishpond was primarily a grazing area in which the fishpond-keeper cultivated algae; much in the way cattle ranchers cultivate grass for their cattle.[3] The porous lava walls let in seawater (or sometimes fresh or brackish water, as in the case of the "Menehune" fishpond near Līhuʻe, Kauaʻi), but prevent the fish from escaping. Fishponds were located next to the mouth of a stream, so by opening a sluice gate the pondkeeper provided the fish with water rich in nutrients that had passed through inland, terraced pondfields and returned to the stream.[3] At the time of Captain James Cook's arrival, there were at least 360 fishponds producing 2,000,000 pounds (900,000 kg) of fish per year.[4]
