State Diagnosis of Macrozoobenthic Biodiversity in the Intertidal Zone of the Sandy Coast of Taghazout (Southwestern of Morocco)

The region of Agadir has experience considerable development for a few years with numerous anchor projects for the various sectors (fishing, tourism, industry, agriculture etc.). Large parts of these development projects are located on the coast. As an example, a new large sea resort called Taghazout Bay (615 ha) is located on the shoreline of Taghazout, about fifteen kilometers from the Agadir city. This tourist project may provoke disturbances on the faunal and floral organizations, as well as on the physico-chemical quality of the seawater and the sediment. Besides the recent study on the microbiological quality of the Taghazout seawater (Lamine et al., 2019) and the study of Donax trunculus dynamics (Lamine et al., 2020), to our knowledge, no ecological study was realized at the coasts of Taghazout. In fact, the studies on the sandy beaches at the regional and national level are still rare. Otherwise, one
