García-Arteaga Biología Cuba coral reefs fish community trophic relations anthropic impacts Changes in fish communities of coral reefs at Sabana-Camagüey Archipelago, Cuba. A comparisonof fish community structure in the Sabana-Camagüey Archipelago (1988-1989 and 2000) using visualcensus surveys (eight belt transects 2x50 m in each site) suggests a notable decrease on species richness, and atwo thirds reduction in fish density and biomass on coral reefs. This decrease in fish populations may be relatedto the alarming decrease of scleractinian coral cover, and an enormous proliferation of algae, which currentlycovers 70-80% of the hard substrate, impeding the recovery of corals and other benthic organisms. High coralmortalities occurred between the study periods, which correlate with the high temperatures caused by the ENSOevents of 1995, 1997 and 1998. These events caused massive bleaching of corals and subsequent algae overgrowth.Evidence of nutrient enrichment from the inner lagoons and overfishing are also present. Collectively,these effects have provoked a marked degradation of reef habitats. These changes appear to have affected theavailability of refuges and food for fishes, and may be constraining individual growth potential and populationsize. Rev. Biol. Trop. 55 (2): 537-547.
