Resumen en inglés

The spotted eagle ray is an iconic species for the recreational diving and snorkeling industry in the Mexican Caribbean although it is heavily fished in nearby waters of the southern Gulf of Mexico and in Cuba. This species is listed on the IUCN Red List of Threatened Species as ‘Near Threatened’ with a decreasing population trend. Few studies have reported on the populations and migrations of spotted eagle rays in the Atlantic Ocean, Gulf of Mexico and Caribbean Sea, and no regulations currently exist for the fishery or tourism industries in Mexico. Photographic identification techniques were used to produce the first photo-ID catalog of spotted eagle rays in the Mexican Caribbean using 1096 photographs submitted by researchers and divers between 2003 and 2016. In total, 282 individual spotted eagle rays were identified through photographs at nine sites across the Mexican Caribbean. Of these individuals, 14.9% were resighted at least once at the same site. The longest period between re-sighting events was 342 days. This is the first study evaluating freeswimming spotted eagle rays in the Mexican Caribbean and highlights the value of using photo-ID for monitoring populations of this ray. Because a targeted subsistence fishery for spotted eagle rays exists in nearby waters, management efforts to monitor and prevent overexploitation at key diving locations should be a priority for local government agencies.
