Illegal Crab Trapping Menace in Cancún: Urgent Conservation Needed

Residents living near lagoons in Cancún have been illegally trapping blue crabs, particularly during their migration period.

The illegal trapping of blue crabs has been identified in Cancún and the continental area of Isla Mujeres. The rains between June and July triggered the movement of these crustaceans, providing an opportunity for locals to trap them.

Gonzalo Aldana Pech, the head of protected natural areas in the northern zone of the Institute of Biodiversity and Protected Natural Areas of Quintana Roo, reported that they rescued around 500 trapped blue crabs last month. However, it's estimated that another 500 were removed from lagoon areas within the protected natural zones of Manatí and Chacmochuch. This was done by individuals who found unguarded fishing sites.

Pech described the trapping area as a 2.5-kilometer strip, extending north from the jetty to the old municipal landfill, and about 500 meters wide. This is where the blue crabs were emerging.

People from Rancho Viejo, primarily from Tabasco and Veracruz, are the main culprits. They consider crab trapping a regular activity and are active both during the day and at night.

Pech explained that trapping was only prevented in June. The issue extends beyond this, however, as authorities can't maintain surveillance at night and in the early morning.

In response, Pech suggested supporting programs that aid in the nesting of these crustaceans to ensure their full migration in the coming months. He emphasized the need for more staff to monitor the protected areas in the northern zone, including Chacmochuch, Manatí, Kabah Park, Selvas, Wetlands of Cozumel, and Laguna Colombia.

Pech also highlighted the importance of blue crab conservation. These creatures consume decaying matter, branches, leaves, fruits, and animal remains. Their burrows help oxygenate the soil, and they are a significant species in the region.

The environmental sanitation program implemented by Ibanqroo, in collaboration with the community guardians of Chacmochuch and the National Commission of Natural Protected Areas, has achieved some success in returning the blue crabs. However, Ibanqroo data reveals that the blue crab population in the Manatí lagoon is almost non-existent, while in the Chacmochuch reserve, it has declined by over 90%.
