| The ecosystem model Atlantis was used to investigate the key dynamics and processes that structure the Eastern English Channel ecosystem, with a particular focus on two commercial flatfish species, sole (Solea solea) and plaice (Pleuronectes platessa). This complex model was parameterized with data collected from diverse sources (a literature review, survey data, as well as landings and stock assessment information) and tuned so both simulated biomass and catch fit 2002–2011 observations. Here, the outputs are mainly presented for the two focus species and for some other vertebrates found to be important in the trophic network. The calibration process revealed the importance of coastal areas in the Eastern English Channel and of nutrient inputs from... |

| Une analyse statistique multivariée a été entreprise sur la base de 11 caractères métriques et 10 caractères méristiques de 3 échantillons de Soleidae appartenant à 2 espèces différentes en provenance de 3 localités distinctes : S. aegyptiaca de Sfax et de Djerba et S. senegalensis de Bizerte. Cette étude a montré une différence significative de certains caractères entre les deux espèces d’une part et au sein de la même espèce péchée dans 2 localités différentes. Le recours aux fonctions canoniques a permis d’élaborer des équations pouvant classer un échantillon dans l’espèce adéquate et dans la localité de sa capture. Une étude complémentaire intégrant toutes les espèces de cette famille, morphologiquement très semblable, pourrait être une méthodologie de... |

| Catch records of flatfishes obtained in exploratory cruises and in the existing literature in the geographical area between 34°S and 55°S in the Western SOuth Atlantic were analyzed to elaborate maps of the distribution of the most common flatfish species in this area. Data from commercial fleet landings at Mar del Plata Harbor were used to analyze the distribution and areas of resource concentration. The flatfish most frequently found in this study area belong to three families: 1. Paralichthidae, with the species: Thysanopsetta naresi, Paralichthys orbignyanus, Paralichthys patagonicus, Paralichthys isoceles, Xystreurys rasile. 2.-Pleuronectidae, with the species: Oncopterus darwini. 3. Achiropsettidae with: Mancopsetta maculata, Mancopsetta milfordi,... |
