Abstract

In this study, phytoplankton abundance, community structure, and physicochemical parameters were investigated for the most famous harbors in Egypt subjected to various anthropogenic wastes. The five studied harbors had > 5mg L─1 for dissolved oxygen and El-Dekhaila harbor was the most oxygenated (6.62mg L─1). The higher significant values of nitrate, nitrite, and total phosphorus were observed in the Western Harbor. While, the highest significant BOD concentration was recorded at El-Dekhaila Harbor. Altogether, 117 species of phytoplankton were identified. Diatoms were the best-represented group, followed by dinoflagellates. Shannon Wiener's (H) diversity index of phytoplankton ranged from 0.203 to 2.872. Additionally, the species richness index (d) ranged between 1.046 and 1.996, and the evenness index (J) was between 0.295 and 0.761. Phytoplankton density showed a wide range between 27.33 × 103 cells L-1 in Damiatta Harbor and 3.06 × 106 cells L-1 in the Western Harbor. The composition and density of the dominant species in the two latter harbors differed compared to the results obtained 30 years ago, showing an increase in the density of winter phytoplankton compared to the formerly recorded data. In conclusion, environmental control assessment studies should be mandatory for upcoming projects at the harbors, with law enforcement, monitoring, and increased awareness being necessary for the coastal administration.
