Diversity and Structure of the Ichthyologic Communities in the Diving Sites in Holguin (Cuba)

This study is aimed to determine the diversity and structure of the ichthyologic communities in the coral reefs of Holguín, Cuba. A total of 85 fish species were recorded, including in 32 families and 53 genera. Low species richness and equitability were estimated at different sampling sites throughout the reef system. Cadena de Vita and Canto Chiquito are the sites with the highest number of species 47 and 46 respectively. Cueva 1 and Punta Naranjo were the places with the highest equitability 0.76. Replacement of fish species among the reef sites studied is poor. Canto Azul with Canto Pionero and La Llanita, sharing 29 species. These results reflect a poor state of conservation of the marine fish communities in Holguín.
