Evaluation du stock de palourdes roses Paphia rhomboïdes en baie de St Brieuc

A drop in the performance of banded carpet shell Paphia rhomboïdes fishing in the Saint Brieuc Bay has been witnessed by the Saint-Brieuc Bay banded carpet shell professional fishermen since 2002. The Ifremer has been asked to assess the state of the banded carpet shell deposit in this fishing area. This mission report presents the results of the banded carpet shell stock evaluation campaign carried out in collaboration with professional fishermen in May 2006 on board the "Narval Bretagne". The results of the direct local small bivalve evaluations of the "Bivalve 2002" campaign conducted in May 2002 on board the research vessel Thalia in the same area are provided as a benchmark.
