Monitoring and Identification of Planktonic Genera/Species and Determination of the Physicochemical Factors Favoring the Growth of These Species in Cape 7 (Aftissat) Zone, South of Morocco

The research was carried out in the region of Cape 7 (Aftissat), south of Morocco, 232 km south of Laayoune. The goal is to define the planktonic genera/species and species 62 km south of Boujdour region. Determination of the physicochemical factors that favour these species’ development. The research was carried out by Carried out on 427 samples, 57.2% (n = 245) of the samples were therefore distributed as follows during the course of the samples. The year 2016 and 42.5 percent in the year 2017 (n = 182). Furthermore, 32.8 percent and 27.6 percent of the samples In winter and fall, respectively, 24.4 percent of the samples were taken in summer and 15.2 percent of all samples were taken in summer. Samples that were taken in spring. A total of 30 species of phytoplankton have been described, of which 70% have been identified. Diatoms are (n = 21), dinoflagellates are 26.67 percent, and silicoflagellates are one species. Additionally, the The most common diatomic species are Navicula sp. (69), Nitzschia sp., Licmophora (47), Pseudo nitzschia spp. (35), (31) and Scrippsiella spp. in the Dinoflagellates class, Protoperidinium spp. (24), Oh. (11). It has also detected several toxic organisms, but with very low frequencies, below the standard. Cape d’Afissat plays a very important role in the economic life of the region, so we must step up our efforts to conserve it and enhance the quality of the water, if possible.
