[Bacterial pollution of the littoral waters of the north of Tunisia (Tabarka and Bizerte regions) and of Lake Bizerte].

The inshore areas of Tabarka and Bizerte are not submitted to the bacterian pollution. The "Old Port" of Bizerte is mainly contaminated all the year round and sometimes polluted the neighbouring urban beach. The lagoon of Bizerte presents any bacterian pollution and could be adapted to the conchyliculture and to the stabulation of Bivalves, with before some important precautions.
