Contraintes du milieu sur les populations de Donax trunculus L. et Donax venustus Poli du littoral atlantique marocain ArchiMer
Guillou, Jacques; Bayed, A.
Populations of Donax trunculus and Donax venustus were sampled along the Moroccan Atlantic coast from Tanger to Tarfaya (Cape Juby) in 1986 and 1987. All the investigated beaches are surf-exposed and belong to the dissipative system. The geographical distribution of the dominant species D. trunculus appears to be obviously influenced by swell-related hydrodynamics. This phenomenon is controlled by the slope on the nearshore side of a critical 30 m depth, and can be expressed in terms of the distance from the coast of the corresponding isobath. A model of adult density distribution is based on this parameter. When the distance in question is less than 2 km, Donax are absent. The maximal densities observed are on the whole weak and suggest the limiting...

Spatial organisation of macrozoobenthic communities in response to environmental factors in a coastal lagoon of the NW African coast (Merja Zerga, Morocco) ArchiMer
Bazairi, H; Bayed, A; Glemarec, M; Hily, C.
Merja Zerga lagoon, located on the Moroccan Atlantic coast, is a site of international value (Ramsar Site) in terms of its ornithological diversity. However, the lagoon is heavily exploited for its clams and fishes. In an effort to further understanding of lagoon ecosystems, and thus to facilitate the management and conservation of their resources, an ecological survey of its benthic component was carried out. Benthos is a valuable food source for birds, fishes and humans. This work involved identifying the macrozoobenthic communities in the lagoon and assessing their spatial distribution. The study was based on monthly sampling of the intertidal zone and seasonal sampling in subtidal zone, over a one-year period. In the intertidal zone, salinity and...
