The 'Ai'opio Fishtrap is a 1.7-acre pond, consisting of a stone and coral wall forming an artificial enclosure along a naturally curving shoreline. The fishtrap had a variety of uses well into recent history, and it remains as a material signature of native Hawaiians' interactions with the sea. Over time, the wall has slowly collapsed. The NPS Submerged Resources Center comprehensively mapped the seawall as an initial measure in restoring the fishtrap wall.

NPS Submerged Cultural Center divers gps surveyed and photographed every part of the 'Ai'opio Fishtrap wall.  This is just one of the many dozens of photopoints used to construct the wall map in the diagram above.
