At the end of this study we have shown that the study of oualidia to azemmour zone contains a very large algal diversity. However, species of economic interest such as Gelidium Sesquipedale (Clemente) Thuret were about to be degraded unconsciously and replaced by other harmful species such as Sargassum muticum (Yendo) Fensholt. An important part of this degradation is from direct discharges into the sea (Domestic and Industrial), without any pretreatment and also the intensive grubbing species on the Atlantic coast. These direct or indirect impacts are not without effect on populations of algae; their effects on our resources are very strong and broad.
