Since the time of their settlement in the Hawaiian Islands, the ancient Hawaiians utilized the practice of fishponds and fish farming to supplement their other fishing activities. Rock walls were constructed at strategic points to allow for fresh water flow in to the pond, but not allow fish to escape. On the southeastern end of Kaua‘i is one of the best examples of an inland fishpond built over 1,000 years ago.

Along the Hule‘ia River is the ‘Alekoko Fishpond with a 5-foot tall lava rock wall that runs an impressive 900 feet in length. The ‘Alekoko Fishpond is fabled to have been constructed by the Menehune—a mischievous race of people who, despite their tiny stature, were capable of performing extraordinary feats such as building the ‘Alekoko Fishpond in only one night.
