“Explore Isla Contoy’s Fish Diversity with Latest CICY Study”

The Yucatan Scientific Research Center (CICY) is currently conducting a study to analyze the diversity of fish species in Isla Contoy. Led by researcher Adán Caballero Vázquez and the Water Sciences Unit, the project's purpose is to compare the species recorded a decade ago with those found today. This comparison will help evaluate the ecological health of the island.

The previous study identified 93 species and 41 families of fish. Vázquez is optimistic that the new analysis will yield similar results. Species that may be observed include the chopa, southeast mojarra, Spanish mojarra, mulatto snapper, and black pipefish. Dominant families such as snappers, mojarras, and mosquito fish have also been identified. These findings underscore the island's importance as a crucial area for marine biodiversity conservation.

So far, two samplings have been conducted, recording 47 species. A final sampling is scheduled for November, at the end of the rainy season, to gather data during the dry period. Preliminary results suggest a predominance of juvenile specimens, indicating a healthy conservation status of the island's ecosystems. Vázquez emphasized the significance of the comparative analysis, noting that the diversity of fish can reveal the extent of any ecological damage or deterioration on the island.

The study, funded by Amigos de Isla Contoy A.C., is carried out in collaboration with the National Commission for Protected Natural Areas (Conanp). It aims to assess whether Isla Contoy remains stable amid potential threats from tourism, boat pollution, and surrounding fishing activities.

The research also seeks to confirm if the island continues to serve as a recruitment center for commercial and ecological species, particularly in lagoon systems, mangroves, and reefs. As a potential refuge for small fish that disperse to other areas as they mature, the island's conservation could hold even greater value.
