In an ocean state that now imports half of its seafood, a determined group of activists is restoring the age-old aquaculture practices of Native Hawaiians.

Despite the hurdles, including many stints in jail, Walter Ritte remains committed to the goal of Native Hawaiian sovereignty · Mickey Pauole
Ritte is a living legend in Hawai‘i’s native rights movement, known across Moloka‘i and beyond as “Uncle Walter.” He radiates an iron core of intensity and conviction that initially intimidates — until he flashes a sudden, crinkly smile so genuine that it brings the sun.

Sources of fresh water such as springs and streams are integral to the Hawaiian fishpond system, providing nutrients that young ocean fish seek out as they develop · Mickey Pauole

In the early 1800s, more than 450 fishponds were dotted around the coastlines of the Hawaiian Islands · Mickey Pauole
Each fishpond is a unique system that requires nearly constant attention from its caretakers · Mickey Pauole
A 12-year study of He‘eia Fishpond correlated two periods of fish die-offs with these weather events. As climate change intensifies, these extremes could happen more often.

Like a living, breathing jewel attached to the shore, the Kupeke fishpond promises a sustainable source of fish · Mickey Pauole
But most important, for fishpond activists, are the connections they have made through this work to an ancient culture stripped from Native Hawaiians over the past two centuries.

Hui o Kuapā

Hawaiian fishpond restoration

Education is the “kua” or backbone of the Hui o Kuapā mission. Hui o Kuapā, founded in 1989, educates the local and global community about Native Hawaiian resource management and innovations through hands-on experience in the fishponds or “loko iʻa” as well as through advocacy of native rights and issues. The organization has been instrumental in raising awareness about the need to care for our planet and food security in rural communities. It proudly continues to carry out that mission today.
