Abstract


The relationship between climate variability and the small-scale fishery (SSF) of the Albuquerque Cays was studied from 2004 to 2018. The environmental variables analyzed were: sea surface temperature (SST), wind magnitude, and chlorophyll (Chl-α). The fishery is multi-species; 410 individuals were identified, belonging to 4 orders, 15 families, and 62 species, of which 38.7% are reef, 35.5% demersal, and 25.8% pelagic. The most dominant species were Caranx latus, Elagatis bipinnulata, Coryphaena hippurus, Lutjanus vivanus, Ocyurus chrysurus, Thunnus atlanticus, Sphyraena barracuda, Canthidermis sufflamen, Etelis oculatus, Acanthocybium solandri, Lutjanus jocu, Balistes vetula, Lutjanus buccanella, followed by Rhomboplites aurorubens and Mycteroperca bonaci. The pelagic species that contribute the most in biomass and commercial importance are S. barracuda, A. solandri, T. atlanticus, and E. bipinnulata, the most important due to their high market value. A significant correlation was found among SST, Chl-α, wind magnitude, and catch per unit effort (CPUE) anomalies. The highest CPUE values occurred in January, March, June and September were associated with the passage of cold fronts and hurricanes, giving way to new fishing opportunities and conservation of some resources.
