Resumo: | The lagoon of Thau is the most important center for the production of cultured shellfish in the South of France. At regular intervals during the Summer, a distrophic crisis happens , locally called "malaïgue"; it can destroy a more or less important part of the livestock . Different ways of reducing this risk have been considered, one of them being the removal of the bottom mud under the rearing structures which is the object of the present study undertaken under IFREMER ' s initiative in Sète. Four experimental sites were observed after the intervention of different types of mechanical appliance used for the removal of a layer of mud. The parameters studied concerned sediment, water and cultured shell- fish, in order to compare the results under mud-cleared structures and check- structures. According to the technical and biological conclusions obtained, the intervention under consideration on all the rearing structures in the lageon seems to be, not only benefic but technically feasible.
