Resumo: | Using Using SCUBA diving, surveying the coral reef communities at four sites, Red Sea Egypt was done. These sites are: Ras El Behar (polluted by petroleum oil), El-Hamraween (impacted by phosphate shipping), Shabrour Umm Gam’ar (harmed by recreational activities and has been suffering from the outbreak of Acanthaster planci during 1998) and Kalawy (a control site). The skeletal growth of the coral Stylophora pistillata was promoted greatly at the expense of other corals, in presence of chronic oil pollution (Ras El-Behar). In contrast, this species was completely suppressed in presence of phosphate and sulphur enrichment. Petroleum oil led to coral scarcity, space monopolization by one coral and increased sea urchins and algae. Coral reefs enriched with phosphate in the field, surprisingly was accompanied by extraordinary well flourishing corals. El-Hamraween was the only site having as higher number and abundance of Acropora as the control site. The abundance of Porites and Pocillopora was higher than the control site. Shabrour Umm Gam’ar, the site suffering from Acanthaster planci outbreak during 1998, was characterized by soft corals which were more abundant than stony corals, indicating that soft corals have higher rate of growth and recovery than stony corals after Acanthaster planci attack. Hydrocorals were abundant in the control site (kalawy).
