A survey of detailed quantitative assessment of the vulnerability of El Mex Bay along Alexandria Mediterranean Coast to the impacts of physical-chemical pollution is presented. GIS tools are used together with many environmental parameters to assess the vulnerability of the most economical and industrial resources along the coast. The coastal bay of El Mex is an important ecological and economical resource whose physical characteristics and location make it particularly vulnerable to the effect of climate changes and pollutants. The ecological study of many planktonic groups such as rotifer assemblages indicated that some rotifers have the ability to exist in polluted waters and are considered as pollution bio-indicators, like Brachionus species and Polyarthra species, several other species considered a mark to certain type of pollution (water acidity, water quality….) as cleared inthis work. El- Mex Bay during the present study involved several types of pollution bio-indicator organisms and it is water contained high chlorophyll concentrations, thus confirming their classification as highly eutrophic and polluted waters and have great impact on the surroundings aquatic system and biological resources.
