This study is trying to assess the types and frequencies of occurrence of coral diseases. Are these diseases due to the impacts of global warming or tourism on coral reefs alongthe Red Sea coast off Hurghada? Resultsindicated that there is a high disease prevalence (46 %) with the presence of fourcoral diseases/ syndromes; White Syndrome (21.6%), Bleaching (16.2 %), BlackBand Disease (8.2%) and overgrowth of sponge were near the sampling transects. Dataof the Coral Reef Watch about the Sea Surface Temperature (SST) anomaly producedby National Oceanographic and Atmospheric Administration (NOAA) indicated that there was 1°C increase in SST in 2009 and 1.5°Cincrease in 2010 in the northern Red Searegion. The increased prevalence of coral diseases in the Red Sea coast off Hurghada might be attributed to sea surface temperature(SST) anomaly due to global warming. Itmight be also due to activities associated with tourism such as exaggerated coastaldevelopment through construction of hotels and increased sewage run off and unregulatedrecreational activities such as SCUBA diving, snorkeling, and reef walking. Coralreefs must be considered and incorporated into management plans. To conservethese valuable marine resources, we have to adopt the sustainability concept ofecotourism instead of mass and random tourism activities. |
