Resumo:
Scleractine corals (Cnidaria: Anthozoa: Scleractinia) are invertebrate organisms and
major builders of coral reefs and reef environments, marine ecosystems of
important ecological relevance. In view of the threats and environmental damage suffered by these
ecosystems, monitoring the health of reef environments is a global goal of
conservation and preservation. The objective of this work was to describe the quali
quantitatively the diversity of stony corals and monitor the health status of the coverage
coralline of the reef environment of Cabo Branco beach João Pessoa – PB, during the
anthropogenic interventions in the works to contain the Cabo Branco barrier. The collections
of abiotic data (salinity, precipitation, dissolved oxygen, surface temperature of the
seawater and atmospheric temperature) and biotics occurred in the period between October 2020
to August 2021, following adaptations of the Agrra protocols version 5.5, and using
the Coral Health Chart for measuring the level of whitening of colonies. The data were
worked according to descriptive statistics in the Excel® program. Among the main
results, there was an investigation that covered 800m2 of the studied reef environment.
accounted for 183 colonies of Siderastrea stellata, of which 36 were recruits (all
healthy) and 147 adults. In this last category, 87.76% were considered healthy, 10.8%
showed a degree of whitening and 1.36% were dead (old events). The data
found in this study demonstrate that the Cabo Branco reef environment is susceptible to
environmental variations and anthropogenic interactions.
