Monitoring of Seahorses in Cozumel: Signs of Ecological Recovery

As part of an ongoing monitoring effort with the Coral Reef Restoration Program (CCRRP) in Cozumel, Mexico, a team of students and researchers is studying seahorse populations (Hippocampus spp.) in the shallow reef area of Villa Blanca, within the CCRRP coral restoration site.

This project was born from a collaboration between CCRRP and Sand Dollar Sports Cozumel, combining science and the diving community, to better understand and protect local marine biodiversity.

This project aims to characterize the local populations of Hippocampus species and their habitats. Through underwater surveys and photographic identification, we collect data on species presence, life stages (juveniles vs. adults), and microhabitat characteristics.

The presence of seahorses in the area has now been definitively confirmed, particularly Hippocampus reidi, but their population density remains unknown. Our goal is to track recolonization trends and understand how are they interacting with the restored environment, especially following the destruction caused by Hurricane Wilma in 2005.

In addition to characterizing the ecosystem, we are also documenting seahorse behavior, noting whether individuals are observed swimming, remaining static, found in pairs, alone, or even pregnant, as has been recorded in recent sightings. Observing seahorses at different life stages provides key information about their reproductive success, population health, and the suitability of the habitat, offering valuable insight for future restoration efforts in the Villa Blanca Shore reef.

This monitoring effort is important not only for informing conservation strategies, but also for guiding responsible management of the reef and its surrounding human activities.
