‘Ai’ai was the son of the Fisherman God, Kuʻula. Many of the fishing grounds and some of the ko‘a (shrines) that were named and created by ‘Ai’ai still remain. The ko‘a are usually circular piles of rock or coral along the shore, visible to fishermen at sea. They were used to give prayer and thanks to the fishing gods. These shrines are still used in ceremonies for abundance and good harvests of fish. It is common to find offerings of shells, ti leaf, seaweed lei and flowers on the ko’a.
