Moliʻi Fishpond is an ancient Hawaiian fishpond on Oahu near Kaneohe, within the ahupuaa of Hakipuu and now part of Kualoa Ranch. Covering about 125 acres, it is one of only four original Hawaiian fishponds still remaining on Oahu. Native Hawaiians used such ponds for ocean husbandry, controlling seawater and fish movement through openings in enclosing walls. Moliʻi is especially known for its roughly 4,000-foot wall separating it from Kaneohe Bay, a structure traditionally attributed to the Menehune and noted for careful stonework. The pond has long supported fish cultivation and commercial harvesting, and more recently oyster production, linking ancient aquaculture with continued use.
