| The Blue Plan scenarios, published in 19891, showed that the protection of the Mediterranean Sea, its shores and coastal regions, could not be achieved through action carried out on the sea or on the coastal regions alone. On the contrary, it depended mainly on the overall development, environment and physical planning policies followed by the Mediterranean countries at the national level. “ Decisions on the bulk of environmental protection will be made (or not) largely at the level of the state. Essential legislation and standards will have to be established at this level, as well as the necessary mechanisms and institutions with the financing and competence to apply them... ”. The Blue Plan then invited the neighbouring countries to change direction and... |

| Several marine campaigns aiming to collect marine demosponges for specific research projects on their taxonomy and biogeography and to study the phenology and distribution of Posidonia oceanica a long the Tunisian coasts were conducted these last 10 years. They allowed a scuba diving prospecting of the infra and circalittoral zones of 555 marine stations. This field work was an occasion to describe some bottom’s associations, to highlight the general state of the main communities, specially the Posidonia and the coralligenous formations, and to draw up a list of their mega benthic species. In general, both biota are well preserved along the Tunisian coasts. except for some black spots, mainly the one of the gulf of Gabes, where detailed analysis showed... |

| La revue des travaux réalisés jusqu’en 2003, relatifs à la systématique des spongiaires, à la bionomie benthique et aux inventaires de la biodiversité marine en Tunisie, ainsi que les nombreuses signalisations récentes, nous ont permis de dresser une liste de 143 espèces de démosponges en Tunisie. Elles se répartissent dans 65 genres, 37 familles et 13 ordres (dont 3 sous ordres), et sont représentées de façon non homogène dans les régions Nord, Sud et Est de la Tunisie. La région Sud est la plus riche aussi bien au niveau générique que spécifique. Ces espèces sont classées en trois groupes différents. Le premier groupe est composé de 33 espèces à large répartition géographique s’étalant du Nord au Sud de la Tunisie ; le second groupe est composé de 37... |
