A decade ago, the overfishing of sea cucumber (Isostichopus badionotus) was the center of controversy in Celestún, a small community in the state of Yucatán, Mexico.

In 2019, the community established the 324-square-kilometer (125-square-mile) refuge zone, the largest in the Gulf of Mexico. The goal was to help recover the sea cucumber — permanently banned from capture — and other species that sustain the local fishing industry, including the red grouper (Epinephelus morio), Mexican four-eyed octopus (Octopus maya) and the Caribbean spiny lobster (Panulirus argus). But the effort wasn’t easy. It required dialogue, organization and the support of local fishing cooperatives, as well as collaboration with the Secretariat of Sustainable Fisheries and Aquaculture of Yucatán (SEPASY) and the Mexican Institute for Research in Sustainable Fisheries and Aquaculture (IMIPAS).
