Cayo Alcatraz


Conservation benefit: New 939-acre no-fishing area for five years  (then subject to renewal)

Community benefit: Lobster shelters to promote sustainable fishery; composting toilets

Date Approved: 06.2020


This project protects mangroves, which trap more CO2 than any other kind of forest and as a result, slow global warming.


This project protects ocean ecosystems, making coastal communities more economically and physically secure in the face of climate change.


This project protects seagrass, which traps more CO2 than any other marine ecosystem, slowing global warming.

This project will bam fishing in a large area of mangroves, coral, and seagrass around Cayo Alcatraz, a small island off the Yucatan Peninsula. Many species of local and migratory birds (ospreys, flamingos, and yellow warblers, just to name a few) are found in these wetlands. There are also many kinds of  sharks, rays, fish, and lobsters.

The idea for the no-fishing zone came from the Mar de las Antillas fishing and tourism cooperative. Its members dive to catch spiny lobsters near the island, but poachers have overfished the area. That has forced the cooperative members to go out into deeper water, where it is more dangerous to dive.

A no-take area will give lobsters a place to grow and reproduce before spreading beyond the protected area. The fishers also want to preserve the natural beauty of the area to attract tourists. They have already reduced their reliance on fishing by embracing ecotourism, highlighting the mangroves and wildlife.

The fishers will patrol the new no-take area and report any violations. Working with our nonprofit partners, they will also ask the government to officially recognize the no-take restrictions.

The cooperative will use a Seacology grant to support tourism and sustainable fishing. They will build restrooms with composting toilets, for local people and tourists. Rainwater collection tanks will store water to irrigate small vegetable gardens. In the protected area, they will install 10 to 15 lobster casitas. These are low shelters that keep small lobsters safe from predators, so that more can reach adulthood. These shelters have been successful in other parts of Quintana Roo, and our project partners will work with experienced installers.

Our local partners are Coral Hero, which has worked with the cooperative on several projects exploring sustainable livelihoods, and Manta Mexico Caribe, which protects manta rays in the Mexican Caribbean.

Project Updates

June 2021

Our project partners have worked on the design of the rainwater harvesting systems and have settled on a composting toilet design. Pandemic restrictions on travel have kept progress slow.

February 2021

The caribeñas (lobster houses) have been designed, and the fishers’ cooperative will buy them once the weather allows construction and transport. Our project partners have made several trips to the site, confirming the coordinates of the no-fishing area and filming the first part of a video.
