Última Effets directs et indirects de la pêche sur des groupes trophiques de poissons démersaux, définis par une approche écomorphologique ArchiMer Reecht, Yves. Functional groups dynamics in marine communities help understanding how perturbations impact the functioning of an ecosystem. It is notably expected that functional groups respond differently to fishing pressure owing to their direct exposure to fishing and interactions between groups (indirect effects). A method was developed, based on an ecomorphological approach focusing on predation functions, to define size- and taxonomy-driven functional groups in demersal fish communities from the Celtic Sea and the North Sea. Eleven functional traits were used to define 12 functional groups in Celtic Sea (based on measurements on 930 individuals from 33 species) and seven groups in North Sea (710 individuals from 22 species). In the Celtic Sea, the functional...

The development of an ecosystemic approach to fisheries management requires the clear formulation of management objectives that make it possible to develop criteria to evaluate indicators. For an ecosystem, targets and limits are a matter of societal choice. Work to formulate these objectives is necessary. Within this perspective, this report presents a survey of the perceptions of Eastern English Channel fishing professionals on the state of the "marine ecosystem" resource. 29 people were polled during the month of June 2006 about their perceptions of the ecosystem as it was at a baseline time in the past, as it is today, and as it should be in future. Diagrams made it possible to formalise these perceptions. The people who were polled noticed a...
