| This study is concerning benthic macrofauna of the bay of Tunis. It permitted to list 214 species distributed into 9.13 % molluscs, 16.8 % crustaceans, 63.5 % polychaeta, etc. Statistic analysis of the data defined four communauties and described them with some synthetic parameters. The heterogenous sediments are extended on a large area and present the higher specific richness (149 species). The communauty is dominated by 2 polychaeta, Glycera convoluta and Lumbrineris fragilis. The muddy sediments are limited to a small area in the center and characterized by a high abundance (4685 ind./m²). The leader species are the polychaeta Melinna palmata and the isopod Apseudes talpa. However, the sandy sediments wich are limitted to the harbor area of Rades,... |
