Abstract The Suez Bay is the connection area between Suez Gulf and Suez Canal and it is important to the Egyptian fisheries. It is subjected to pollution from three main sources: i 1 industrial waste products which come from great factories viz: two oil refineries, a fertilizer company and power station, ii) domestic drai.nage of Suez city and iii) ships’ oil spills and refuses. The most subtle pollution source on the plankton, which constitute the main food for fishes is the oil refineries including El- Nasr and Suez petroleum companies which discharge about 7.44 tons/year of heavy petroleum fractions, as well as the contaminated ballast water discharged in the Bay from vessels awaiting berth at the post and oil docks or in transit through the Suez Canal. So that, the study of effect of oil pollution on the quantity and quality of free floating microphytes (phytoplankton) in the oil polluted sites is very important for comparing the result with a control region which is far away from the pollution sources. Water and phytoplankLon samples were monthly collected at three stations from January to December 1992, and the locations of this stations can be described as follows. |
