Fouling in the southern region of the Suez Canal

Fouling in the southern region of the Suez Canal 1. The area investigated embraces Suez harbour, El Shalloufa, Geneva, Kebret (at the Bitter Lakes), Devresoir and Tossoum pilotage stations. It extends about 75 km along the Suez Canal. 2. The Suez-Geneva section is poorly fouled, mainly due to the high silt content of the water. At Suez the standing crop of fouling reached its lowest value in the Canal (0.02 g/cm2/month). 3. Settlement was much greater on the long-term panels than on the panels exposed for one month, but reached a constant weight after about two months of exposure, apparently due to the accumulation of silt which prevented the attachment of many organisms. 4. Fouling was equally poor at all depths down to 5.5.m below the water surface, but a small increase was noticed at the uppermost 1.5 m of the water column. 5. The standing crop of fouling steadily increased northward and was found 0.14 g/cm2/month in Tossoum. 6. Kebret, representing the Bitter Lakes, was found densely fouled with calcarious animals, particularly bryozoans. 7. Ascidians and the amphipods are very common in Tossoum and Devresoir. 8. The presence of a local, southward current in the Canal, even after damming of the River Nile, is discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aquatic Ecology Springer Journals

Abstract

1. The area investigated embraces Suez harbour, El Shalloufa, Geneva, Kebret (at the Bitter Lakes), Devresoir and Tossoum pilotage stations. It extends about 75 km along the Suez Canal. 2. The Suez-Geneva section is poorly fouled, mainly due to the high silt content of the water. At Suez the standing crop of fouling reached its lowest value in the Canal (0.02 g/cm2/month). 3. Settlement was much greater on the long-term panels than on the panels exposed for one month, but reached a constant weight after about two months of exposure, apparently due to the accumulation of silt which prevented the attachment of many organisms. 4. Fouling was equally poor at all depths down to 5.5.m below the water surface, but a small increase was noticed at the uppermost 1.5 m of the water column. 5. The standing crop of fouling steadily increased northward and was found 0.14 g/cm2/month in Tossoum. 6. Kebret, representing the Bitter Lakes, was found densely fouled with calcarious animals, particularly bryozoans. 7. Ascidians and the amphipods are very common in Tossoum and Devresoir. 8. The presence of a local, southward current in the Canal, even after damming of the River Nile, is discussed.
