The objectives of the SEMER project were to establish prospects for the evolution of seeding practices of shells exploited in the Bay of Brest by exploring the possibilities of extension of these practices (spatial, specific, regulatory). The various facets of these coastal activities, of biological, ecological, socio-economic and legal nature, are being investigated during field surveys. From these surveys, a series of workshops will be organized between scientists and professionals of these activities as well as managers of the coastal zone in order to co-construct scenarios for the adaptation and/or the transformation of these activities in the context of global change. Also, this project aimed (i) to conduct interviews with all the actors directly or indirectly related to these activities (professionals, scientists, local authorities) and (ii) to organize workshops bringing together these actors to launch the co-construction of scenarios regarding the evolution of these activities in the Bay of Brest. These workshops were organized by a group of Master students from the EGEL Master programme.
The Bay of Brest
For several decades, the Bay of Brest has been seeded with shellfish juveniles produced at the Tinduff cooperative hatchery in order to increase the stocks exploitable by the local fishery, following the decline of natural populations since the 1960s. Technically this practice is intermediate between fisheries and aquaculture but falls under fisheries regulations. The increase in temperature with climate change as well as the deterioration of the quality of the water in relation to toxic micro-algae blooms, endanger this fishery and raise many questions about the evolution of the activities of fisheries and aquaculture in this environment. The question of the diversification of the species to be exploited sustainably arises and requires the development of scenarios of evolution of these activities in the short and medium term. Restocking actions could be envisaged, but their success would require the definition of management and exploitation methods allowing both the restoration of the populations and habitats to which they are associated and a reasoned exploitation.
