Le programme de repeuplement de coquille Saint-Jacques : finalité, résultats et perspectives

The king scallop (Pecten maximus L.) has been the object of some in-depth studies since 1973 with the double aim of natural resources management and extensive aquaculture in mind. The results obtained during the first ten years enabled the launch of a pluri-annual 1983-1987 program which aims to demonstrate the re-populating of the roadsted of Brest and the introduction of new management methods in the Bay of Saint-Brieuc. The technical results of the resource management and of the aquaculture operations are described. They enabled the stabilisation of the annual production of the Saint-Brieuc deposit as well as to foresee a new biomass of 80-100 tonnes of spawners per year in the roadsted of Brest. However, the implementation of all these developments is not yet possible because of the human context of fisheries. The economic, social and legal data are important constraints that are currently discussed.
