Oneisomw Island

June 2019

Conservation benefit: Five no-take marine zones, totaling 10,403 acres, for 10 years

Community benefit: Community resource center

Chuuk Lagoon, one of the largest lagoon systems in the world, is filled with an amazing variety of sea life. More than 250 species of reef fish are found there. Mantas, sharks (gray, blacktip, and whitetip reef shark), and green and hawksbill sea turtles are common.

The reefs around Oneisomw, a volcanic island in the westernmost part of the lagoon, were once full of large fish. But now, because of overfishing, all that has changed. Fish are scarcer; sea cucumbers, sea snails, and giant clams have nearly vanished.

To reverse this trend, the people of Oneisomw will ban fishing in five areas of the lagoon, totaling more than 10,000 acres. These areas contain mangrove forests, seagrass, and reefs. Closing a reef, sometimes for years, is a traditional practice (mechen) in Chuuk.

Four of the five proposed no-take areas are visible from land, making enforcement relatively easy. Community members will patrol the fifth area, with government support once the legislature makes the reserve part of the Chuuk Protected Area Network.

The communities are working with the mayor, the Micronesia Conservation Trust, the Oneisomw Resource Management Committee, and Director of Chuuk Marine Resources. A fisheries management plan for areas outside the no-take area includes gear bans, size restrictions and species bans, and limits on where and when commercial fishing can take place.

A Seacology grant will fund a community center on the main island of Weno, a 90-minute boat ride from Oneisomw. Women from Oneisomw go there to sell produce, and teenagers go to Weno for high school. The center will give women a place to sell their wares and a venue for youth activities: studying, tutoring, and a safe place to congregate as they wait for boats home.
