This paper presents the evolution of aquaculture in North Africa during the 20 last years, and the assets and bottlenecks for each country. This work uses the results of the European project Aquamed (2011-2013). The analysis of the evolutions of this sector, including research and development allows to establish a diagnosis on the strengths and the weaknesses in the four countries (Morocco, Algeria, Tunisia and Egypt). The retrospective analysis helps in identifying solutions for a more sustainable development. It also contributes to select priorities for action in a long-term vision (2035). This double overview, on the past and the future, should help decision-makers and experts to identify the best politics for a sector, which has a high potential in the...

Understanding the factors explaining the observed patterns of genetic diversity is an important question in evolutionary biology. We provide the first data on the genetic structure of a Mediterranean octocoral, the yellow gorgonian Eunicella cavolini, along with insights into the demographic history of this species. We sampled populations in four areas of the Mediterranean Sea: continental France, Algeria, Turkey, and the Balearic and Corsica islands. Along French coasts, three sites were sampled at two depths (20 and 40 m). We demonstrated a high genetic structure in this species (overall F-ST = 0.13), and most pairwise differentiation tests were significant. We did not detect any difference between depths at the same site. Clustering analyses revealed...
