Bivalve farming is in France a major economical activity, which development was initiated in the mid of last century. It occupies nowadays 24 000 ha of seabottom, leased from the French State, and production figures are above 100 000 tonnes for cupped oyster and 40 000 tonnes for mussel ; these made a gross value of 1 300 millions francs in 1983. Moreover, it shows potential for promising development, by expanding to new areas, especialy in deep sea, or by introducing new species, such as the short neck clam, which production has just reached significant level (300 T in 1984). Long age and success of this cultivation activity come from the important advantages related to the biology and ecology of bivalves: food naturaly available, and of no use by another... |

France is presently one of the leading countries in Europe for shellfish production with 152,000 metric tonnes of the Pacific cupped oyster C. gigas, 2,500 tonnes of flat oyster O. edulis, and more than 60,000 tonnes of mussels M. edulis and M. galloprovincialis. Moreover, species like the pearl oyster Pinctada margaritifera in French Polynesia, and on the Atlantic coastline the scallop Pecten maximus and the Manila clam Tapes philippinarum contribute significantly to the overall landings. . Since traditional rearing areas are now almost overloaded, new management practices are currently under review to optimise and develop shellfish culture. Besides the products resulting from genetic research (e.g. triploids, tetraploids and disease resistant strains),... |

Historically, research involvement in shellfish industry appeared as soon as the 19th century with studies on oyster sanitary quality and nutritive values. Those aspects were developed to satisfy consumer's demand and public health issues. Later on, rearing technologies were developed to ensure optimization of the characteristics of shellfish population dynamic such as recruitment, growth, and mortality. In a third step, management of leasing grounds allocation required studies on ecosystems' functioning. It integrated over space and time relationships between environment (as a trophic resource) and shellfish production. Presently, new challenges regarding environmental protection and consumer's satisfaction have involved studies on optimized uses of... |
