Kalepolepo Fishpond

Kalepolepo Fishpond is an ancient Hawaiian fishpond estimated to have been built between 1400 and 1500 CE.
The fishpond is located in Kalepolepo Park in Kihei, Maui. In 1996, the Aoao O Na Loka Ia O Maui began renovating Koieie, working closely with the Hawaiian Islands Humpback Whale National Marine Sanctuary.
Koieie is classified as a loko kuapa, a type of fishpond that uses lava rock and coral walls to keep water circulating while a wooden sluice gate allows small fish to enter the pond to feed, but prevents them from leaving after they grow too large to slip between the gate's gaps. Species of fish once farmed by ancient Hawaiians include the awa, amaama, and the aholehole.
The fishpond was listed on the National Register of Historic Places in 1996, as Kalepolepo Fishpond with alternate names Koieie Fishpond and Kaonoulu Kai Fishpond.
