Última A new innovated and cheep model in building artificial reefs OceanDocs Mahmoud, M.A.; Ammar, M.S.A.. A novel and cheep approach for building artificial reefs was designed in such a way that sediments in an area of high sedimentation rate will be utilized in building the artificial substrate with no further sediment accumulation afterwards. The model consists of several steel cylinders which are soldered together in such a way to form a reef flat, a gentle slope and a steep slope, with two layers of narrow opening meshes (a lower plastic and an upper metallic one). Within a short periode (3 months), a substrate layer of a total of ~ 1 cm was formed between the two meshes, this layer increased to ~2 cm after 9 months. Transplants of the three species Stylophora pistillata, Echinopora gemmacea and Montipora spongiosa grow better when the attaching surface is...

Using SCUBA equipment and the line intercept transect (LIT), the effect of physical factors and human impacts on coral distribution were studied in two Red Sea sites (Sharm El Loly and Tobia Kebir) throughout the period from September, 2003 to October, 2004. The percentage cover of coral species in Northern Sharm El Loly was higher than in Tobia Kebir which might be attributed to optimum temperature and better light intensity. Diving, swimming, boat anchoring and fish feeding by divers are the main human impacts decreasing the percentage cover of corals at Tobia Kebir but fishing seems to have no role due to its limited level. The lower recorded amount of dead corals at Sharm El Loly though it is highly affected by fishing boats, is due to the fact that...
