| Between 1980 and 1986, some Arcachon oyster farmers took up breeding the Japanese clam on the foreshore (Robert et Deltreil, 1990). This production was short lived. The steep fall in prices due to economic competition from Spain, Portugal, Italy and Tunisia, predator action such as the trigger fish (Popovsky et al., 1999), added to the significant amount of mortality that occurred in the summer and autumn of 1992 that affected two-thirds of the total stock, led to clam farming being abandoned at the end of the 1980s. In the Arcachon basin, the Japanese clam (Ruditapes philippinarum) population, now natural to the area, has found favourable conditions for development and is expanding rapidly there. This species has been supplanting the local species... |

| Introduction: With the objective of diversifying current fishing and at the request of professionals in Aquitaine, the Regional Commission of Maritime Fishing and Marine Breeding (CRPMEM) of Aquitaine has started a discussion about the possibilities of opening a shellfishery. In the context of this course of action, and because of the absence of information on the presence and size of the resource, the CRPMEM of Aquitaine asked IFREMER's Halieutic Resources Laboratory of Aquitaine (LRHA) for assistance in acquiring information on the subject. At the same time, a prospective analysis study of the exploitation of shellfish off the coast of Aquitaineregulation and business sectionwas performed by the CRPMEM of Aquitaine (Coiffec, 2006). At that same time,... |

| Scampi (Nephrops norvegicus) is traditionally fished with bottom trawls on muddy grounds. Some trawlers from Bayonne fish it from May to August in the south of the Bay of Biscay. The Capbreton area is partly forbidden to trawling and net fishing (see appendix 1) In spring and summer, it is frequented by a fleet of about fifteen vessels, among which are some lining vessels, fishing hake, and a few pot vessels, targeting crabs. Some of these vessels could be interested in using scampi traps in this area in order to be more versatile and, to a certain extent, to diminish their economical vulnerability through a diversification of the revenues generated by another high market value species. Ifremer offered to assess a new tool: scampi trap, on the Basque and... |
