Huilua Fishpond

Huilua Fishpond is a large historical water enclosure in Kahana Bay built with a substantial rock seawall stretching roughly 500 feet. Two sluice gates control water movement between the ocean and freshwater sources, allowing the pond to maintain conditions suited for raising mullet and young fish.

The fishpond was built between 1200 and 1600 and represents one of the few surviving examples of large Hawaiian aquaculture installations. Of the original 97 fishponds once lining Oahu's coast, only six remain today, highlighting how rare and significant this structure has become.

The fishpond served as a shared resource where a local keeper oversaw fish distribution and maintained traditional practices central to community life. Local residents depended on the regular harvest, making this an important part of how neighbors worked together and fed their families.

The fishpond is easily visible from the public shoreline along Kahana Bay, making it simple to spot from the main access points. Visiting in the early morning offers the best experience, as the water is usually calmer and fewer people are around.

Stone shrines called ko'a were positioned near the pond where people left offerings to encourage fish reproduction and abundance. These sacred sites reveal how fishing and spiritual beliefs were deeply connected in daily life.
