Abstract
This study allows us to have an overall idea about the qualitative and quantitative status of macrozoobenthos that is rich and diverse. It is highly endangered due to human activities. The development of actions to promote conservation, including the establishment of a monitoring system and monitoring of key species is essential. The inventory macrobenthic species of the subtidal zone during 4 years 2009 to 2012 of follow-up shows the distribution uneven in different taxa by a dominance of sponges presented by 25 species, molluscs represented by 20 species then cnidarians by 15 and echinoderms by 9, crustaceans are the least represented, these fig.s reflect the strength from our quantifications and not reality. The results obtained after prospecting the sub-littoral different stations show a clear qualitative and quantitative difference between sites close to human actions (settlements, infrastructure, industry and pollution) and those far to the east and the West on the one hand and between sites hard or soft substrate on the other. The most represented groups correspond to sponges, cnidarians, echinoderms, crustaceans and mollusks bivalves and gastropods.
