Cancún Launches Operation to Protect Blue Land Crabs During Migration to the Sea

Cancún, Quintana Roo — Municipal officials, environmental agencies and volunteers have launched an operation to protect blue land crabs at three sites in Cancún as the crustaceans make their annual migration from the mangroves to the sea.

Fernando Haro Salinas, director general of ecology for Benito Juárez, said the effort runs Sept. 25 to 27, a period tied to the lunar phase in which the crabs leave mangrove areas and head for the coast to deposit their eggs. Patrols are concentrated at Playa del Niño, Playa Las Perlas and Punta Nizuc, where the largest numbers of crabs have been recorded during the migration.

Volunteers Help Crabs Cross Roads

During the three-day program, staff from the participating agencies and volunteers walk the routes to spot crabs heading toward the beaches and help them move safely. The greatest risk comes when the animals must cross roads or areas with vehicle traffic, where they can be struck and killed.

Haro Salinas stressed the importance of protecting every crab because of its reproductive capacity, noting that a single crab can release up to 800,000 eggs once it reaches the sea.

“Every crab is fundamental to our ecosystems,” the official said.

Agencies and Volunteers Join the Effort

The operation involves agencies from all three levels of government, including the Federal Attorney’s Office for Environmental Protection (Profepa), federal environmental authorities, the Traffic and Public Services Department and staff from the Benito Juárez city government.

They are joined by citizen volunteers who take part in the patrols and help carry crabs to safety when necessary. As part of the campaign, preventive banners were also installed at the identified sites to warn drivers about the presence of crabs on the roads.

Drivers Asked to Slow Down

Authorities urged motorists traveling near Playa del Niño, Playa Las Perlas and Punta Nizuc to reduce their speed and drive cautiously in the coming days. They called on drivers to stay alert for crabs on the roadway and avoid running them over, especially during the periods of heaviest movement toward the sea.

Monitoring will continue throughout the three days covered by the program to reduce risks and help the crabs complete their journey to the coast.
