Hervé Le Bris


Ma thématique de recherche actuelle est centrée sur les habitats benthiques et l'écologie trophique des communautés bentho-démersales des zones côtières et estuariennes abritant des nourriceries de poissons et des fermes aquacoles. L'objectif général est d'évaluer la qualité écologique et le fonctionnement de ces ésosystèmes.
Cette recherche repose sur l'étude de communautés de poissons benthiques et démersaux et leurs relations trophiques (prédation, compétition) avec les communautés d'invertébrés benthiques (macro- et mégafaune). Cette recherche a aussi pour but de définir les limites des apports terrestres de nutriments dans les chaînes trophiques benthiques du littoral au talus continental (-200 m).
D'un point de vue plus appliqué, cette recherche explore, à partir de l'analyse des réseaux trophiques, la réponse d'écosystèmes aquatiques aux pressions anthropiques liées à l'aquaculture (poissons ou coquillages) et l'agriculture (marées vertes).
