First Inventory of the Biodiversity of Aquatic Macroinvertebrates of Lake Sidi Boudaroua Ouazzane, Morocco

Natural lakes are a strategic reservoir for water resources and are also a bank for species in aquatic environments. Macroinvertebrates are considered the best bioindicators reflecting the state of these lakes. The objective of the current study was to inventory the aquatic macro-invertebrates of Lake Sidi Boudaroua Ouazzane, Morocco. Based on the observations under the microscope and the identification of species using identification keys, a clear idea of the trophic state of the environment was attained. From the results of these analyses, a results matrix was assessed. Consequently, descriptive statistical analyses were applied with the SPSS analysis software. These results showed that a distribution of species has made it possible to highlight a seasonal temporal variation. A number of 237 individuals collected at the 3 sampling sites distributed in 11 orders, 22 families, and 26 genera testify to a good diversity of the Lac Sidi Boudaroua. The most abundant family is the Scarabaeidae (Coleoptera). The biodiversity of macroinvertebrates reflects a significant floristic richness in the case of macrophytes and phytoplankton. Further taxonomic studies of all the biodiversity would make this site a real zoological and botanical garden that would attract not only researchers but also tourists and investors.
